Text A BUILDING MATERIALS
In order to build a house the civil engineer must consider many important factors: the choice of materials, their physical properties, availability, cost, etc. Materials to be used for structural purposes should meet a number of requirements. In most cases they should be strong, durable and fire-resistant.
Steel, concrete, stone, timber and brick are the most commonly used building materials. Timber is the oldest structural material known to mankind. It is light, cheap and easy to work with. But timber has certain disadvantages: it burns and decays. Timber used for building purposes is divided into two groups: softwoods and hardwoods. Softwoods are chiefly used in construction, while hardwoods are generally used for decorative purposes.
Bricks were known many thousands of years ago. They are molded from clay into the required shape. Bricks are usually rectangular in shape. They are hardened by being fired in a kiln.
Concrete is one of the most important building materials. It is difficult to imagine modern structures without concrete. Concrete is made by mixing together a proportion of fine and coarse aggregates with cement and water. Crushed stone, broken brick and gravel are considered to be coarse aggregates. Sand is the best fine aggregate. Both quarry and river sands are extensively used.
Reinforced concrete is a combination of two of the strongest structural materials available — concrete and steel. There are two kinds of reinforced concrete: with ordinary reinforcement and concrete with prestressed reinforcement. Concrete is reinforced by the incorporation of steel rods.
Plastics and glass reinforced plastics are comparatively new building materials, but they have already found many uses in modern construction. Plastics combine all the best characteristics of building materials with good insulating properties. Plastics are produced from chemicals. Glass-reinforced plastics are produced from polyester resins reinforced with glass fibres. Plastics and glass-reinforced plastics are the materials to be used in modern construction on a large scale.

Text C. REINFORCED CONCRETE
Reinforced cocrete is a combination of two of the strongest structural materials, concrete and steel.
This term is applied to a construction in which steel bars or heavy steel mesh are properly embedded in concrete. The steel is put in position and concrete is poured around and over it, then tamped in place so that the steel is completely embedded. When the concrete hardens ans sets, the resulting material gains great strength. This new structural concrete came into practical application at the turn of the 19th century. The first results of the tests of the reinforced concrete beams were published in 1887. Since that time the development of reinforced concrete work has made great progress. And the reasons of this progress are quite evident. Concrete has poor elastic and tensional properties, but it is rigid, strong in compression, durable under and above ground and in the presence or absence of air and water, it increases its strength with age, it is fireproof.
Steel has great tensional, compressive and elastic properties, but it is not durable being exposed to moisture, it loses its strength with age, or being subjected to high temperature. So, what is the effect of the addition of steel reinforcement to concrete.?
Steel does not undergo shrinkage or drying but concrete does and therefore the steel acts as a restraining medium in a reinforced concrete member. Shrinkage causes tensile stresses in the concrete which are balanced by compressive stresses in the steel. For getting the best from reinforced concrete the following consideration should be kept in mind:
1. For general use the most suitable proportions of cement and aggregate are: I part cement, 2 parts sand and 4 parts of gravel.
2. only fresh water free from organic matter should be used for reinforced work. Sea water is not allowed.
3. Homogeneity of the concrete is a very important requirement.
Steel costructions with reinforced concrete have become the most important building materials invented in centuries and they have given modern architecture its peculiar features.
Exercise 5. Make up your own topic «Building Materials» on the base of the three texts.
LESSON 8PARTS OF A BUILDING
TEXT A. THE VARIOUS PARTS OF A BUILDING
A building consists of two main parts: the substructure and the superstructure. The substructure is the part of a building below ground level. It includes the footing, the basement and the foundation walls. The superstructure is the part of a building above ground level. It includes the walls, floors, roofs, beams, columns and trusses.
To build a house first the excavation must be dug for the basement, then the foundation walls are constructed. After that the framework is erected, sheathed with various finishing materials and protected by several coats of paint.
The foundation is the lowest part of the structure upon which the superstructure rests. Foundations are usually made of monolithic concrete, concrete blocks, piles or bricks. They keep the walls and floors from contact with the soil, support the superstructure and prevent the building from sinking.
Walls enclose internal spaces and support the weight of the floors and roof. Non-structural subdividing walls are called partitions. Walls also protect the interior from exposure to the weather. They are made of wood, brick, stone, concrete, concrete blocks, reinforced concrete and/or other natural or artificial building materials.
A window is an opening in the wall of a structure which lets the light and air. Doors are constructed in walls to allow access. Floors divide a building into storeys. They may be of timber or constructed from fire-resistant materials. At present floors finished in wood or linoleum are very popular.
Stairs are a succession of steps connecting two spaces located at different levels. They may be of wood, stone, reinforced concrete or metal.
A roof is the topmost part of a building. Roofs cover the building and protect it from exposure to the weather. They should tie in the walls and give strength and firmness to the whole structure. Roofs must be well framed, strong enough to resist winds, sustain snow loads and serve as insulation to prevent heat transmission.
Today every building should be beautiful in appearance, well proportioned and provided with all modern conveniences such as running water, gas, central heating, ventilation, air conditioning, waste disposal and telephone points.

But you didn’t.
TEXT B. PILE FOUNDATIONS
Pile foundations are being used on a large scale in Russia. Their use makes it possible to achieve considerable reductions in the volume of concreting and to increase the use of prefabricated elements. Piles also speed up foundation work, reduce labour costs and increase reliability. Piles enable foundations to be built in all seasons, and eliminate the need for digging frozen ground. Subsidence with pile foundations is 80 per cent less than in conventional foundations. This is particular important in the construction of buildings with large wall panels, which are highly sensitive to uneven subsidence. Pile foundations are therefore being applied extensively in this type of building. The most common type of piles is a prefabricated, reinforced concrete pile, either solid or hollow.
Research is going on into the question of reducing the amount of piling required for a given building, the reinforcement required, while simultaneously increasing the cross section and load-bearing capacity. This refers to piles with prestressed reinforcement, and hollow piles. Piles of square section with a round cavity are being used, together with tubular piles.
The hollow square piles require less concrete, and are lighter, it makes them easier to drive. The tubular piles, up to 80 cm in diameter are more economical than solid piles. Furthermore, because of their large diameter and great load-bearing capacity, the number required can be reduced. This type of pile has been found most useful where it must pass through poor soil and enter relatively strong soils.
TEXT C. ELEMENTS OF STRUCTURE
In discussing the materials in construction, we have also been considering many of the elements of architectural construction such as walls, columns (or posts), beams, openings (windows and doors), roof coverings, arches. Both the materials used and the elements of construction were clearly associated with the practical function of each building.
The wall… As an architectural element the wall may vary in thickness, height, shape (curved, straight, elliptical), completeness, manner of construction, basic function, and ultimate esthetic purpose and effect. In some styles of architecture, the wall as a wall is more important than in others, either for decorative or for functional reasons. In the chapel, e. g., the false wall is an area to be covered with ornament and is otherwise relatively functionless. In the house, the wall is a partly limiting, partly liberating surface, without ornament of any kind.
In some styles of architecture the wall is more important as a «bearing» or carrying element, that is, for functional reasons. This is seen in Romanesque, Egyptian, Renaissance, and many other traditional styles where the walls are the building, carrying themselves as well as the floors.
Ornament, in the traditional sense, is almost completely absent from the modern building, which relies on the texture and color of its walls and similar elements for decorative embellishment.
Windows and Doors. Windows and doors constitute the two chief types of openings. Their purpose is to afford ready access of light, air and entry for occupants. Different climates and purposes naturally require different types of windows and doors. Even in traditional architecture it was evident that whereas it was desirable to admit light in northern buildings where there was relatively little sun, in southern buildings it was far more advisable to keep sun out.
Windows and doors whether traditional or modern, are also important elements in the decoration of the building and its design qualities.
Doors are also part of the a esthetics of a building. In some buildings their effect is far less than in others — deliberately so. In traditional architectural forms, doorways often have a ceremonial purpose associated with a religious or royal procession and therefore carry importance in the architectural scheme together with their symbolic meaning.
Exercise 7. Make up your own topic «Parts of a Building».
LESSON 9: Heating, Ventilation and Air Conditioning
Text A. Heating, Ventilation and Air Conditioning
Ex 1. Read and translate the text. Work with the vocabulary and find Russian equivalents to the words marked out in the text.
There are two branches of engineering: heating and ventilation. They are very closely connected. Both are concerned with providing a required atmospheric environment within a definite space.
Air-conditioning is related to heating and ventilation. The most widely used system of heating is the central heating system. The term “central heating” applied to the heating of domestic and other buildings indicates that the whole of a building is heated from a central source. In the central heating system the fuel is burned in one particular place. It may be the basement of a building or a specially designed room for the purpose. Then from there steam, hot water or warm air is transmitted to all the necessary places to be heated.
Heating system has the two most common systems: the hot water system and the steam system.
The hot water system consists of a boiler and a whole system of pipes, which are connected to all the radiators in the building. The pipes are usually made of steel, but they can be made of copper too. The cooled water is returned to the boiler where it is reheated.
The steam heating system consists of the single-pipe system and the two-pipe system. In the single-pipe system the steam is conveyed to the radiator through a pipe at the bottom of one of the end sections. In the radiator forms the condensation, which flows back through the same pipe.
In the two-pipe system a separate system of piping is provided. It carry away the condensation and in some cases the air from the radiator.
Of course, ventilation of buildings is a very important factor in modern structures. It receives proper attention in housebuilding, because every person in the building should have plenty of fresh air.
ventilation – вентиляция, heating – отопление
air-condition – кондиционирование воздуха radiator – радиатор
to apply – применять, to be heated – отапливаться
to be transmitted – передаваться uel – топливо,
to be burned – сжигаться, basement – подвал
a single-pipe system – система с одной трубой pipe – труба
steam – пар ,boiler – котельная,
to be connected – быть соединенным ,
to be reheated – быть повторно нагретым ,
copper – медь, to be conveyed – передаваться
domestic building – жилое здание
central heating system – система центрального отопления
Ex. II. Answer the questions:
1. What branches of engineering are very connected?
2. Is air-conditioning related only to heating?
3. Where does the central heating apply?
4. Where is the fuel burned?
5. Call the two most common systems of heating?
6. What does the hot water system consist of?
7. How many systems does it include?
8. What can you say about the single-pipe system?
9. What can you say about the two-pipe system?
10.Why is ventilation of buildings a very important factor in modern structures?
Ex. III.. Translate the dialogue into English using words and phrases from the text and tell it in pairs.
А: Можешь ли ты мне сказать, какая система отопления наиболее широко используется?
Б: Я не специалист в этой области, но я уверен, что это система центрального отопления.
А: Правда ли, что в системе центрального отопления топливо сжигается в специальном для этого месте?
Б: Да, ты абсолютно прав. Этим местом может быть подвал здания или специально созданная для данной цели комната.
А: Затем оттуда пар, горячая или теплая вода передается во все необходимые места, чтобы они отапливались.
Б: Ты прав. Это то, что мы называем системой центрального отопления.
Ex IV. Tell about heating, ventilation and air conditioning.
Ex 5.Read and translate the text. Give the text a suitable title.
When designing a small home that is to be air-conditioned, many important factors must be considered to achieve economical installation and low operating costs. A system controlling the temperature, humidity and filtering of the air is adequate for home conditioning.
Units with very accurate controls, as used in industrial or large commercial installations, are not required for small residences.
A house to be efficiently and economically air-conditioned should be designed so that the heat gain is as low as possible. This is achieved by proper orientation, location of glass areas, and insulation and ventilation of roof. Natural elements such as trees, planting and water areas should be utilized to provide shade and cooling.
It is not necessary to have a sealed house or a square plan to air-condition efficiently. For the sake of economy and efficiency in the small home the center core plan is often advised. The central service core has the following advantages: 1. Economical structure. 2. Grouped plumbing. 3. Efficient ductwork. 4. Flexibility of plan around core to utilize orientation.
The air conditioning unit should be located in the center of the plan to minimize ductwork and insulation. Oversize units are as inefficient as undersize conditioning units. The proper unit that will operate steadily, rather than in surges of cooling periods, will provide better results, because between surges humidity builds up and destroys the comfort balance. Ideal interior humidity is 50%.
The cost and availability of electricity and water should be obtained to estimate operating costs of equipment. If supply of water is limited or expensive, conditioning systems with water saving devices are necessary.
Ex VI.a) Give synonyms to the following words:
to use home to be located
to design possible
b) Give antonyms to the following words:
important, expensive ,a small residence
Text C: “Designing a Heating System.”
In general, a heating system should be designed so that the water will circulate by gravity. In some installations, circumstances are such that a pump or accelerator must be used to achieve a satisfactory circulation. This should be avoided if possible.
When designing a heating system for a large building, it is usual – in the interests of economy and to ensure efficient heating – to first calculate how much heat will be needed to maintain the building at the desired temperature. Then the size of the boiler and the amount of pipe and radiator heating surface required to give out this heat will be estimated. For small systems, “rule-of-thumb” methods and past experience are generally a sufficient guide.
The overhead drop-feed system shows how the hot water from the boiler is carried as high as possible in the building, from where it falls in cooling, through the various branch pipes and radiators, back to the boiler. In this type of system, the maximum amount of “circulating head” or pressure, would be obtained.
Ex 7.Find out the beginning of the following sentences:
1)… will circulate by gravity.
2)… will be estimated.
3)… are generally a sufficient guide.
4)… would be obtained.
LESSON 10 LET EARTH BE SAVED
Ex. 1. Work with the vocabulary and find Russian equivalents to the words marked оut in the text " LET EARTH BE SAVED"
Text 1. LET EARTH BE SAVED
Look around you. Just think what the situation is like. People may be suffering from cholera, typhoid or dysentery. Or it could be that somebody you know has cancer, allergy or bronchitis. What is the reason for all this?
Doctors may list thousands of causes. But, if you go deep into the problem, you will understand that the atmosphere around us is severely polluted. Rather, we have destroyed the environment to such an extent that the water we drink, the food we eat, the air we breathe and the land we live and grow our food on, are no longer safe. They are a source of danger to us, as much as we are dangerous to Nature around us.
In fact thousands of animals, birds and plants which lived for millions of years, have now become extinct.
Just consider for a moment! We will exhaust all available resources of oil in about two decades. Likewise, resources like coal, iron, gold and copper may not even last our lifetime. So, by the time we die, we would have ensured that our children will never know what petrol or kerosene is like. They will probably never see any of these and many more.
It could be argued that plastics could replace metals. But are plastics and synthetic materials bio-degradable? When a leaf falls from a tree, it is eaten by insects or becomes manure for plants. Bad enough, plastics are not absorbed in the soil. Worse, they are harmful if they are allowed to remain so.
Similarly, consider a nuclear plant. We all know, that uranium [ju/ reini m] breaks down when struck with a neutron. Energy is the result. But what happens to the fission fragments and other products that are not used? You cannot throw them away as garbage is thrown away. A people in the neighbourhood are get fatal diseases. Such nuclear wastes have to be stored till such time they lose their potency. So the question of safely storing them arises. After all we would not like to be victims ourselves.
These are just superficial questions about environment before us. By all our actions, we are destroying Earth. We have to help ourselves to prevent dreaded problems such as industrial pollution, shrinking rain forests, ever expanding deserts, ozone holes, over-population, acid rain, river and ocean pollution and many more.
How do we do this? People concerned the world over have been thinking on these lines for well over 40 years. Later, well-meaning people from all round the globe came together to celebrate the «International Earth Day» on April 22 each year. And last year, people from over 134 countries participated in these celebrations. Many more countries participated this year.
The aim of «Earth Day» is to create an awareness among people to save the environment.
June 5 is World Environment Day. It marks the anniversary of the Stockholm Conference on Human Environment held in Sweden in 1972. At this historic conference, nations of the world gathered to share their concern over human progress at the expense of the environment. The meeting called upon the world community to work towards «development without destruction».
Two decades later the United Nations Conference on Environment and Development began in Brazil on Environment Day. As governments around the world are discussing regional and global environmental issues, it is a good time to educate and inform ourselves about our immediate environment and work towards improving it.
• Get to know your own neighbourhood better.
• Bring the residents together to share their concerns about local environmental problems and identify the most pressing ones.
• Organise a neighbourhood environment squad to tackle the problems. No one is too old or too young to pitch in .
On this day let us solemnly reaffirm our commitment to the Stockholm Declaration to ensure, collectively and individually, that our small planet is passed over to future generations in a condition which guarantees a life with human dignity for all.
You can make a difference too, no matter how small your contribution may seem. Add these to your New Year resolutions:
• I will switch off the lights when I am last person to leave a room.
• I will walk or cycle whenever I can, rather than use a fuelconsuming vehicle .
• I will tightly close any tap I see dripping .
• I will not litter.
These resolutions are not at all difficult to keep, but they will make a difference — not just to you, but to the earth we all share
Ex. 2. Arrange in pairs of antonyms.
healthy, polluted, destroy, global, expanding, living, deep, enrich, dangerous, shrinking, clean, sale, extinct, save, exhaust, superficial, harmful, region
Ex. 3. Do you agree or disagree with the following statements? Discuss and give your reasons. Use the following expressions of agreement and disagreement; I couldn't agree more. Absolutely. Exactly. Well, actually, I'm not sure I agree with that. I disagree entirely. Rubbish.
1. Doctors may list thousands of causes for different diseases but if you look deep into the problem, in the long run they all result from the severely polluted environment.
2. The costs of growth and development are already too high and the future is bleak.
3. Providing that development is controlled, it can do no harm.
4. We need to rethink our whole way of life and live in small communities which only produce the food and goods they need.
5. It's ridiculous to expect people to give up the benefits of civilisation and go back to the Dark Ages even if at the expense of the environment.
Ex. 4. Answer these questions (Use vocabulary from the text).
1. Which environmental problems does your town, village or city suffer from? Which are the most serious?
2. Do you think the situation in your country is better or worse than in other countries?
3. What can you do to help your local environment?
4. Can anything be done about global environmental problems? Can the world community solve them and on what conditions?

Text 2. THE ENVIRONMENTAL CRISIS
We are in an environmental crisis because human beings have broken out of the circle of life and are destroying the environment. To survive, we must learn how to restore the wealth we have borrowed from nature.
A. What does the environmental crisis mean? To understand this we must begin at the source of life itself: the earth's thin skin of air, water and soil, bathed by the radiant solar fire. Life appeared here several billion years ago and was nourished by the earth's matter. Living things formed a global network of various habitats, where everything is directly or indirectly dependent on everything. This is the ecosphere (biosphere), the home that life has built for itself on the planet.
B. In nature all processes are in constant balanced interaction. There is no waste in nature. Nothing is created, nothing is lost. Everything is recycled endlessly. The environmental crisis means that this perfect and delicate balance has begun to break down, and the relationship between life and its earthly surroundings have begun to collapse.
C. The environmental degradation continues to accelerate. The ozone layer, vital for survival, is thinning. Acid rain is destroying huge areas of forest and tens of thousands of lakes. We pollute our rivers, lakes and oceans, and the sky, forgetting that we need water and air to live and breathe. We destroy rainforests, picturesque landscapes, and slaughter the world's most beautiful animals.

LESSON 11 Modern Architecture
Ex. l. Work with the vocabulary and find Russian equivalents to the words marked оut in the text «MODERN ARCHITECTURE»
Text A. Modern Architecture
Modern architecture is the term universally applied to the style of building, which evolved in a number of countries after the First World War as the International Style, or Functionalism, and which has culminated in the current designs of glass, concrete and steel based on module construction presently being erected all over the world.
In the early 20th century an instinctive desire of architects to break away from the confusions and contrivances of the 19th century, and their efforts to introduce a style which responded to new social needs and exploited new materials led to the changed appearance of buildings; simple rectangular outlines; avoidance of symmetry as a result of the insistence of a building's function determining its form rather than some picture in the architect's mind; absence of applied ornament; flat roofs and white walls, resulting from the use of reinforced concrete, now the favourite material; large windows, which new structural techniques permitted, but which were encouraged too by the spirit of the times, which believed in opening up the interiors of buildings to light and air.
The development of the International Style was reinforced by two events: a series of exhibitions at which architects from different countries saw and were influenced by each other's experiments, and the formation of an international organization through which ideas could be exchanged and mutual support enjoyed.
Exhibitions provided opportunities to explore an environment created wholly by modem buildings; they had been experienced only as single structures against an alien background.
The international organization was the Congres Internationaux d'Architecture Modeme, known as CIAM. Founded in Switzerland in 1928, the organization lasted until 1959 and concerned itself especially with planning and the social role of architecture. During the period of ClAM's greatest influence, in the 1930s, among its members were most of the great architects of the day, including Walter Gropius, Le Corbusier and Alvar Aalto. Athens Charter is a manifesto published by the CIAM in 1933, setting out data and requirements connected with the problem of the modem city under 5 main headings: Dwelling, Recreation, Work, Transportation, Historic Buildings. The pioneers of modem design wanted to build constructions that reflected the modem age.
Until the 1930s, Germany was the main centre of the new architecture because of the presence there of another unifying institution, the Bauhaus, a college of design, established at Weimar by Walter Gropius in 1919. The Bauhaus became synonymous with modern teaching methods in architecture and the applied arts, and with a functional aesthetic for the industrial age.
In the yea's after 1945 the emphasis was on town-planning and housing, and in most countries also on legislation to control building in the public interest, in which activities Britain set the lead. This was the era of new towns, vast housing estates and attempts to gear building programmes both to social needs and to industrialized systems and techniques.
In matters of architectural style, it became less a question of conflict between period revival and modern design than between buildings designed for effect and those that aimed at the creation of a modem vernacular and a humane and harmonious environment.

Text B THE AGE OF REVIVALS
The Industrial Revolution, which introduced new materials and techniques, made the 19th century the time of the vast expansion of cities or urbanization in Europe and America. Then more buildings were constructed than in all previous ages added together.
The role of the architect was merely confined to decorating the building facades. Throughout Europe nearly every past style was re-examined and reused, but as the century wore on styles of the past were no longer imitated exactly, but were looked on as a quarry from which architects could extract whatever elements struck their fancy. A succession of rival styles came, vied with each other and went, some conforming conscientiously to historic precedent, but many more mingling reminiscences of different periods and countries. This resulted in either beautiful or graceless eclecticism. Richness of form and picturesqueness of effect were the principal aim.
Styles began to be chosen not just for fashion but for their associative qualities:
Roman for justice, Gothic for learning and churches, Byzantine mainly for churches, the Italian Renaissance for palaces and ministries, Greek for government, Venetian for commerce. Oriental for leisure, Hansetic for housing, the Baroque for theatres and opera houses, Romanesque for public architecture. Colonial for bank buildings, churches and suburban homes. Nevertheless, the 19th century revival architecture was dominated by the Classic Revival, or Neo-Classicism, and the Gothic Revival, or Neo-Gothic.
A reaction against stylizations came nearer the end of the century. It, too, was concerned with decoration more than construction, and aimed at creating a style -especially a style of ornament — that owed nothing to the past. It emerged as Art Nouveau in France and Belgium, a little later as Jugendstil in Germany, and spread throughout Europe and reached the USA.
Behind this picturesque play-acting glittered the iron and glass architecture of the engineer-experimentalist, who created the impressive array of simple, dignified and refreshingly functional buildings, the viaducts, dockyards, textile mills and railway stations. There was Paxton's Crystal Palace (1851), one of the most revolutionary buildings in the history of world architecture, and the daring towers or skyscrapers of the Chicago School (1880-1900).
The «Japonism» of the Aesthetic Movement, the Arts and Crafts movement, the preachings of William Morris against opulence and the tyranny of the machine, the stirrings of Art Nouveau and the folksy aspirations of the garden city movement can now be seen to have been the ancestors of modem architecture.

TEXT A. СOMPUTER SIENCE
Computer science is a part of an applied mathematics. Computers are intended to improve the productivity of labour or scientists, designers, engineers, managers and other specialists. Through a computer they can receive quick and optimal solutions. The specialists use computer-aided-design (CAD) and computer-aided-manufacturing (CAM). CAD and CAM help to shorten the time between designing and manufacturing.
Computer can perform many functions: they can do mathematical and logical operations, mathematical operations including arithmetic and algebraic operations, such as addition, subtraction, multiplication and division raising to a power differentiating and integrating. Logical operations include comparing, selecting, sorting and matching. Computers can be divided into simple and complex devices. Simple computers are calculators. A calculator can perform addition, subtraction, multiplication and division. Complex computers can do various logical operations and some of them even have artificial intelligence.
Complex computers can be divided into following main classes:
— minicomputers (personal computers)
A minicomputer is a computer manufactured on a single printed board which contains one or more chips. Most microcomputers are personal computers which have become so powerful through using CAD/CAM system. Microprocessors can obtain from memory and execute a limited set of instructions in order to perform addition or subtraction on a binary world and to input or output binary data.
Memory is a device for storing digital information. Memory should be small in size and large in capacity. It must take little power and work at the same speed as computer logic. All microcomputers use Random Access Memory (RAM) and Read Only Memory (ROM). Trough RAM the information can be put into or out of any single byte of memory. ROM is permanent memory for program storage . People know many types of memory units. Hard disks and floppy disks are widely used. Floppy disks (flexible plastic disks) are used in personal computers.
Thus in order to elaborate up-to-date and inexpensive programs as well as to defend them from viruses, it is important to know some programming languages: machine language (low-level programming language) and an assembly language and high-level languages such as FORTRAN, PASCAL, ADA, C, BASIC etc.
Modern personal computers are used for automation of individual labour places, information processing and training. Moreover, computers came in our life and to our houses and now we can solve our everyday problems with their help.

TEXT B GATEWAY 2000
There are many hardware pieces such as the system board, power supply, keyboard, mouse, hard drive, monitor, video card with its drivers in a computer system.
The system unit contenting power supply, system board, etc has the main part called the case. The case is a metal box that protects the delicate electronics inside, keeps electromagnetic emissions inside so your TV, cordless phone and stereo don’t go haywire when you power up the computer and can also hold the monitor. Don’t remove the case cover unless you need to do something inside the unit, and always replace the cover when you are done.
You communicate with your computer with the keyboard. You type instruction and commands for the computer with it information to be processed and stored. Many of the keys on the keyboard are like those on a typewriter; letter keys, punctuation keys, shift keys, tab and the spacebar. Your keyboard also has many specialized keys.
The instruction manuals for most software applications contain a section describing the functions of each key or combination of keys.
The mouse works by sliding it around (ball down) on a flat surface. The desktop is fine, but a ready-made mouse pad is the best surface to roll the mouse on. Its surface is flat and usually somewhat textured. If the surface is too smooth or rough, the ball inside can slip. As you glide the mouse, the ball inside moves in the direction of your movement. You will see the arrow on your screen moving in unison. The arrow is called a pointer, and the most important part is the very tip of its point. That’s the only part the computer pays attention to. To use the mouse, slide it on the mousepad until the pointer’s point is on something like a button or an icon.
Click – position the mouse pointer over an element, press and release the left mouse button one time.
Double-click – same as above except press the mouse button twice in a quick succession without moving the mouse between clicks. Usually you double-click on an icon to start the program.
Drag – position the mouse pointer over an element, press and hold the left mouse button, and drag the mouse across the screen. The pointer moves dragging the element. At the desired location, release the mouse button. The pointer lets go of whatever it was dragging.
Your computer is not complete without the monitor, a TV-like device that usually sits on top of the computer. The monitor displays text characters and graphics. It allows you to see the results of the work going on inside your system unit. The sharpness of the picture depends on the number and size of pixels (tiny dots). The more pixels, the sharper the image. This is called resolution.
There are three types of drives. The floppy drive provides a way to pass files to and from the hard drive or to and from another computer. Unlike the floppy drive, the hard disk drive is inside the computer case and you cannot see it. The smallest hard drives Gateway 2000 offers hold more information than 100 floppies! The size of a hard drive is measured in megabytes or MB for short. The CD-ROM drive is installed in the Gateway 2000. It can play music CDs as well as read software program CDs and the new Kodak photo CDs. A CD disk holds over 600MB of data. CD-ROM is just another hard drive, except that, although you can read from it, you can’t save anything to it. All of them have its drivers.
Ex. VI. Reread the text and write a short summery of it in English.
