Text B. Three basic steps in the computer

Input

A program provides the basic instructions the computer must follow in order to do a specific job. Like the basic rules of a game, the program is only the beginning, however. In order to do a job, the computer and the program must also have input (вхідні дані). Input is the data and additional instruction you give to a computer to enable it to do a specific job. The input may be in the form of numbers, letters, words, or pictures.

The computer may receive input through a keyboard (клавіатура), which looks very much like the keyboard on an ordinary typewriter (друкарський пристрій). It may also receive input from a disk or cassette. Until a computer receives input, it can do nothing.

Processing

What does a computer do with the information it receives? Like the human brain, it sorts information, puts it into usable form, and does calculations. This step is called processing.

Output

Finally, the computer does something with the information it processes. It usually displays the results, often on a screen or on paper. The product of computer processing is called output (вихідні дані). Output is the information the computer produces as a result of its work.

You are likely to see this three-step process – input, processing, output – in many day-to-day (повсякденний) activities, such as when you use a pocket calculator. In a calculator the input consists of numbers that you press on its keypad (додаткова цифрова клавіатура) – let’s say the numbers 3 and 7. The processing occurs after you tell the calculator what you want it to do for example, multiply. The output – 21 – appears on a little screen at the top of the calculator.

The calculator can process the same information in different ways. You might have asked it to add the two numbers, in which case “10” would have appeared on the screen.

Text A. INTERNET AND MODERN LIFE

The Internet has already entered our ordinary life. Everybody knows that Internet is a global computer network, which embraces hundreds of millions of users all over the world and helps us to communicate with each other.

The history of Internet began in the United States in 1969. It was a military experiment, designed to help to survive during a nuclear war, when everything around might be polluted by radiation and it would be dangerous to get out for any living being to get some information to anywhere. Information sent over the Internet takes the shortest and safest path available from one computer to another. Because of this, any two computers on the net will be able to stay in touch with each other as long as there is a single route between them. This technology was called packet switching.

Invention of modems, special devices allowing your computer to send the information through the telephone line, has opened doors to the Internet for millions of people.

Most of the Internet host computers are in the United States of America. It is clear that the accurate number of users can be counted fairly approximately, nobody knows exactly how many people use the Internet today, because there are hundred of millions of users and their number is growing.

Nowadays the most popular Internet service is e-mail. Most of the people use the network only for sending and receiving e-mail messages. They can do it either they are at home or in the Internet clubs or at work. Other popular services are available on the Internet too. It is reading news, available on some dedicated news servers, Telnet, FTP servers, etc.

In many countries, the Internet could provide businessmen with a reliable, alternative to the expensive and unreliable telecommunications systems its own system of communications. Commercial users can communicate cheaply over the Internet with the rest of the world. When they send e-mail messages, they have only to pay for phone calls to their local service providers, not for international calls around the world, when you pay a good deal of money.

But saving money is only the first step and not the last one. There is a commercial use of this network and it is drastically increasing. Now you can work through the Internet, gambling and playing through the net.

However, there are some problems. The most important problem is security. When you send an e-mail, your message can travel through many different networks and computers. The data is constantly being directed towards its destination by special computers called routers. Because of this, it is possible to get into any of the computers along the route, intercept and even change the data being sent over the Internet. But there are many encoding programs available. Notwithstanding, these programs are not perfect and can easily be cracked.

Another big and serious problem of the net is control. Yes, there is no effective control in the Internet, because a huge amount of information circulating through the net. It is like a tremendous library and market together. In the future, the situation might change, but now we have what we have. It could be expressed in two words – an anarchist dream.

VIII. Translate the text using a dictionary.

Text B. ROM (read-only memory)

A computer has to have a built-in set of instructions. It has to know what to do when it is turned on. Different computers have different kinds of instructions in ROM (ПЗП – постійно запам’ятовувальний пристрій), but some instructions are standard and necessary for all computers. For example, all computers have to know how to do various mathematical computations. The computers can “read” or follow the instructions in ROM but it cannot change them. That’s why the memory is called “read-only”.

RAM (random-access memory)

RAM (ОП – оперативна пам’ять) is the memory that holds the software and other input data while you are working on them. This kind of memory is called random access (довільний доступ) because you can instantly go right to any part of the stored data or program. You do not have to run through all the data stored up to the part that you want to see.

You can easily change input data that is stored in RAM. For instance, you can add a missing name or correct a misspelling. However, many commercial software producers write their programs in such a way as to make it very difficult for you to change them.

RAM is temporary memory. When you turn off the computer, everything that has been stored in RAM disappears. If you want to save data that is stored in RAM, you have to store it externally – that is, outside the computer.

The amount of RAM varies from one computer model to another. But no matter how much RAM your computer has, it is not unlimited. At some point, the memory will be filled. When that happens (or even before it happens) you will need to transfer data from the filled internal storage to some form of external storage.

Text A. THE FUTURE OF THE INTERNET

Everywhere we go, we hear about Internet. It’s on television, in magazines, newspapers, and in schools. One might think that this network of millions of computers around the globe is as fast and captivating as television, but with more and more users logging on everyday and staying on longer and longer, this “Information Superhighway” could be perhaps more correctly referred to as an expressway of big city center at rush hour.

It is estimated that thirty five to forty millions users currently are on the Internet. According to a recent statistics, an average Internet call lasts five times as longer as the average regular telephone call. 10 percent of the Internet calls last 6 hours or longer. This can cause an overload and, in turn, cause telephone network to fail. The local network was designed for short calls which you make and then hang up, but Internet calls often occupy a line for hours. With so many users in the Internet and their number is growing by 200 percent annually, it certainly provides new challenges for the telephone companies. The Internet, up to the beginning of the 90s, was used only to read different texts. Then in the early 90’s, a way was made to see pictures and listen to a sound on the Internet. This break-through made the Internet to be most demanded means of communication, data saving and transporting.

However, today’s net is much more than just pictures, texts, and sound. The Internet is now filled with voice messages, video conferencing and video games. With voice messages, users can talk over the Internet for the price of the local phone call. Nowadays we no longer have to own a computer to access the Internet. Now, devices such as Web TV allow our television to browse the Web and use Electronic Mail. Cellular phones are now also dialing up the Internet to provide E-mail and answering machine services. The telephone network was not designed and built to handle these sorts of things. Many telephone companies are spending enormous amounts of money to upgrade the telephone lines.

K. Kao and G. Hockman were the first to come up with the idea of using fiber optic cables, as opposed to copper wire, to carry telephone signals. Fiber optics uses pulses of light to transmit binary code, such as that used in computers and other electronic devices. As a result the amount of bandwidth is incredibly raised. Another solution for the problem is fast modems which satisfy the need for speed.

By accessing the Net through the coaxial cable that provides television to our homes, the speed can be increased 1,000 fold. However, the cable system was built to only send information one way. In other words, they can send stuff to us, but we can’t send anything back, if there is no modem available.

Yet another way is being introduced to access the Internet, and that is through the use of a satellite dish just like the TV dishes currently used to deliver television from satellites in space to your home. However, like cable connection, the information can only be sent one way.

Faster ways of connecting to the Internet may sound like a solution to the problem, but, just as new lanes on highways attract more cars, a faster Internet could attract many times more users, making it even slower than before.

To help solve the problem of Internet clogs, Internet providers are trying new ways of pricing for customers. So, in business time any connection to Net cost more than your connection in the night.

In conclusion, I should add that if we want to keep the Internet usable and fairly fast, we must not only improve the telephone lines and means of access, but also be reasonable in usage.

Text B. Storage methods

You lose any program and data stored in RAM when you turn off the computer. The only way to save a program and data is to store them externally – that is, outside the computer. Once you’ve stored data externally you can load it back into RAM. In this way the storage medium is also a form of input.

Programs and data are stored on disks or flash-memory in the form of magnetic impulses. When you load a program or data into the computer, these impulses are “read” and the data are sent into RAM. The procedure is somewhat like playing a record. When you put a record on your turntable (опорний диск елекропрогравача) the grooves are “read” by the stylus (відтворювальна голка) and the impulses are sent to the system’s amplifier and speakers (гучномовець). The grooves containing the music remain on the record; they do not have to be recaptured and stored again.

Cartridge

A cartridge is a small plastic box that contains a permanent program, somewhat like ROM. The box, about the size of a pocket calculator, plugs into a slot in a microcomputer. Cartridges are often called ROM cartridges because they have read-only memory. As a user, you cannot store anything new on a cartridge. You can only use what is put there by the manufacturer.

Cartridges are fully enclosed (у закритому виконанні) and sturdy (міцний).

Cassette

A cassette is a small reel of magnetic tape in a plastic case – exactly like a music cassette but containing a computer program instead of music. By attaching a simple, fairly inexpensive cassette recorder to some microcomputers, cassette tapes can be used to store programs and data.

Since information must be stored in sequence on the tape, the material stored at the end of the tape can be reached only by running through the whole tape up to that point.

The main advantage of a cassette over other kinds of storage is its comparatively low cost. The main disadvantage is that there is slower access to data with a cassette than with some other storage devices.

Text A. DATA PROCESSING AND DATA PROCESSING SYSTEMS

The necessary data are processed by a computer to become useful information. In fact, this is the definition of data processing. Data are a collection of facts – unorganized but able to be organized into useful information. Processing is a series of actions or operations that convert inputs into outputs. When we speak of data processing, the input is data, and the output is useful information. So, we can define data processing as a series of actions or operations that convert data into useful information.

We use the term “data processing system” to include the resources that are used to accomplish the processing of data. There are four types of resources: people, materials, facilities, and equipment. People provide input to computers, operate them, and use their output.

The need for converting facts into useful information is not a phenomenon of modern life. Throughout history, and even prehistory, people have found it necessary to sort data into forms that were easier to understand. For example, the ancient Egyptians recorded the ebb and flow of the Nile River and used this information to predict yearly crop yields. Today computers convert data about land and water into recommendations to farmers on crop planting. Mechanical aids to computations were developed and improved upon in Europe, Asia, and America throughout the seventeenth, eighteenth, and nineteenth centuries. Modern computers are marvels of an electronics technology that continues to produce smaller, cheaper, and more powerful components.

Five basic operations are characteristic of all data processing systems: inputting, storing, processing, outputting, and controlling. They are defined as follows.

Inputting is the process of entering data, which are collected facts, into a data processing system. Storing is saving data or information so that they are available for initial or for additional processing. Processing represents performing arithmetic or logical operations on data in order to convert them into useful information. Outputting is the process of producing useful information, such as a printed report or visual display.

Controlling is directing the manner and sequence in which all of the above operations are performed.

It is known that data, once entered, are organized and stored in successively more comprehensive groupings. Generally, these groupings are called data storage hierarchy. The general groupings of any data storage hierarchy are as follows.

1. Characters, which are all written language symbols: letters, numbers, and special symbols.

2. Data elements, which are meaningful collections of related characters. Data elements are also called data items or fields.

Text B. Operating systems

An operating system provides the basic instructions that tell the computer how to handle certain tasks necessary for it to work. The operating system of a large computer can be very complicated, because it has to control so many functions. A microcomputer’s operating system is simple by comparison.

Suppose you had a computer with no operating system. (Yes, there are such machines.) You would have to write a program – a very complex program – in order to get the computer to do anything. Among other things, you would have to explain in your program how the computer should interpret the pressing of each key. Such a computer provides good training for a computer scientist, but it is of little value to most ordinary users.

An operating system gets you over that hurdle (перешкода). It consists of a set of prewritten instructions. The operating system is the program that makes it possible for you to run all other programs that are available or can be written for your computer. The operating-system program may exist just in ROM. Or it may exist partly in ROM and partly on a disk or tape.

Disk operating systems

A disk operating system (дискова операційна система), or DOS is a program that controls the storage of information on disks. DOS also makes it possible for the computer to use various programs that are already stored on disks. Most packaged programs for computers are available on disks, and the DOS is what gets these programs started. Obviously, the system requires a disk drive (дисковод).

Text A. ADVANTAGES OF COMPUTER DATA PROCESSING

Computer-oriented data processing system or just computer data processing systems are not designed to imitate manual systems. They should combine the capabilities of both humans and computers. Computer data processing systems can be designed to take advantage of four capabilities of computers.

1) Accuracy. Once data have been entered correctly into the computer component of a data processing system, the need for further manipulation by humans is eliminated, and the possibility of error is reduced. Computers, when properly programmed, are also unlikely to make computational errors. Of course, computer systems remain vulnerable to the entry by humans of invalid data.

2) Ease of communications. Data, once entered, can be transmitted wherever needed by communications networks. These may be either earth or satellite-based systems. A travel reservation system is an example of a data communication network.

3) Capacity of storage. Computers are able to store vast amounts of information, to organize it, and to retrieve it in ways that are far beyond the capabilities of humans. The amount of data that can be stored on devices such as magnetic discs is constantly increasing. All the while, the cost per character of data stored is decreasing.

4) Speed. The speed, at which computer data processing systems can respond, adds to their value. For example, the travel reservations system mentioned above would not be useful if clients had to wait more than a few seconds for a response. The response required might be a fraction of a second.

Thus, an important objective in the design of computer data processing systems is to allow computers to do what they do best and to free humans from routine, error-prone tasks. The most cost-effective computer data processing system is the one that does the job effectively and at the least cost. By using computers in a cost-effective manner, we will be better able to respond to the challenges and opportunities of our post-industrial, information-dependent society.
