Part 1 Computer applications
1. Read the text and discuss with your partners each speaker’s job and what each speaker uses their computer for.
electrical engineer secretary librarian composer |
A. I write music mainly for videos and plays. I work on a keyboard connected to a computer. I use the computer in two ways really; first of all, to record what I play on the keyboard, in other words, to store what I play on the keyboard. Secondly, the computer controls the sounds I can make with the different synthesizers. The computer is the link between the keyboard which I play and the synthesizers which produce the sounds.
B. I use my computer to do the usual office things like writing memos, letters, faxes and so on, but the thing which I find really useful is e-mail. We are an international company and we have offices all over the world. We are linked up to all of them by e-mail. With e-mail I can communicate with offices around the world very efficiently. It has really changed my life.
C. Well, I use computers for almost every aspect of my job. I use them to design electrical installations and lighting systems: for example the program will tell you how much lighting you need for a particular room, or how much cable you need, and it will show where the cable should go. I also use the computer to make drawings and to keep records. We have to test our installations every five years and the information is stored on computer.
D. I use computers to find information for people. Readers come in with a lot of queries and I use either our own database or the national database that we are connected to find what we want. They might want to know the name and address of a particular society or last year’s accounts of a company and we can find it for them. Or they might want to find a particular newspaper article but they don’t know the exact date it was published so we can find it for them by checking on our online database for anything they can remember: a name or the general topic. And we use computers to catalogue the books into the library and to record the books that readers borrow.
2. Give English equivalents
Решать сложные проблемы, погодные условия, база данных, полагаться на, хранить информацию, высокая скорость, выполнять, соединять.
3. Write a list of as many uses of the computer, or computer applications, as you can think of.
4. Now read the text below and underline any applications that are not in your list.
What can computers do?
Computers and microchips have become part of our everyday lives: we visit shops and offices which have been designed with the help of computers, we read magazines which have been produced on computer, we pay bills prepared by computers. Just picking up a telephone and dialing a number involves the use of a sophisticated computer system, as does making a flight reservation or bank transaction. We encounter daily many computers that spring to life the instant they're switched on (e.g. calculators, the car's electronic ignition, the timer in the microwave), all of which use chip technology.
What makes your computer such a miraculous device? Each time you turn it on, it is a “tabula rasa” that, with appropriate hardware and software, is capable of doing anything you ask. It is a calculating machine that speeds up financial calculations. It is an electronic filing cabinet which manages large collections of data such as customers' lists, accounts, or inventories. It is a magical typewriter that allows you to type and print any kind of document — letters, memos or legal documents. It is a personal communicator that enables you to interact with other computers and with people around the world. If you like gadgets and electronic entertainment, you can even use your PC to relax with computer games.

Part 2. What is a computer?
Exercise 1. Read the text and translate it into Russian.
What is a computer?
Computers are electronic machines which can accept data in a certain form, process the data and give the results of the processing in a specified format as information.
Three basic steps are involved in the process. First, data is fed into the computer's memory. Then, when the program is run, the computer performs a set of instructions and processes the data. Finally, we can see the results (the output) on the screen or in printed form.
Information in the form of data and programs is known as software, and the electronic and mechanical parts that make up a computer system are called hardware.
A standard computer system consists of three main sections: the central processing unit (CPU), the main memory and the peripherals.
Perhaps the most influential component is the central processing unit. Its function is to execute program instructions and coordinate the activities of all the other units. In a way, it is the 'brain' of the computer.
The main memory holds the instructions and data which are processed by the CPU. The peripherals are the physical units attached to the computer. They include storage devices and input/output devices. Storage devices ( hard or optical disks) provide a permanent storage of both data and programs.
Input devices enable data to go into the computer's memory. The most common input devices are the mouse and the keyboard. Output devices enable us to extract the finished product from the system. For example, the computer shows the output on the monitor or prints the results onto paper by means of a printer.
On the rear panel of the computer there are several ports into which we can plug a wide range of peripherals - modems, sound systems, optical drives and scanners. These are the main physical units of a computer system, generally known as the configuration.
Exercise 2. With the help of the text match the terms with the definitions.
a. software | 1. The brain of the computer. |
b. peripheral devices | 2. Physical parts that make up a computer system. |
с. monitor | 3. Programs which can be used on a particular computer system. |
d. central processing unit | 4. The information which is presented to the computer. |
e. hardware | 5. Results produced by a computer. |
f. input | 6. Hardware equipment attached to the CPU. |
g. port | 7. Visual display unit. |
h. output | 8. Any socket or channel in a computer system into which an input/output device may be connected. |

Types of computers
1. Before reading, answer these questions.
-
Have you got a computer at home, or work? What kind is it? -
How often do you use it? What do you use it for? -
What are the main components and features (the configuration) of your computer system?
Digital computers can be divided into five main types, depending on their size and power: they are mainframes, minicomputers, desktop PCs, laptops and handheld computers.
'Mainframes' are the largest and most powerful computers. The basic configuration of a mainframe consists of a central system which processes immense amounts of data very quickly. This central system provides data information and computing facilities for hundreds of terminals connected together in a network. Mainframes are used by large companies, factories and universities.
'Minicomputers' are smaller and less powerful than mainframes. They can handle multi-tasking, that is, they can perform more than one task at the same time. Minicomputers are mainly used as file servers for terminals. Typical applications include academic computing, software engineering and other sophisticated applications in which many users share resources.
PCs carry out their processing on a single microchip. They are used as personal computers in the home or as workstations for a group. There are two classes of personal computer: (a) desktop PCs, which are designed to be placed on your desk, and (b) portable PCs, which can be carried as a tiny notebook. This is why they are called 'netbooks' and 'laptops'. The latest models can run as fast as similar desktop computers and have similar configurations. They are ideal for business executives who travel a lot.
2. Choose the correct answer.

-
a mainframe computer is less powerful than a minicomputer -
a mainframe is more powerful than a minicomputer -
a mainframe is not very powerful but can execute jobs very rapidly
2 Mainframe computers are used by:
-
students and teachers -
executives and businessmen -
large organizations processing enormous amounts of data
3 'Multitasking' means:
-
access to a minicomputer through terminals -
doing a number of tasks at the same time -
connection to a 'host' computer network so that many users have access to data and programs
4 The most suitable computers for home use are:
-
mainframes -
minicomputers -
microcomputers (PCs)

5. Study these details of different types оf computer. Find the answers to these questions. Which type of computer is:
-
the most common? -
small enough for a pocket? -
the most common portable? -
used by many people at the same time? -
used like mainframes -
the most powerful? -
not suitable for a lot of typing?
Types of computer | Notes |
Mainframes | Large, powerful, expensive. Multi-user systems - used by many people at the same time. Used for processing very large amounts of data. The most powerful mainframes are called supercomputers. |
Minicomputers | Used like mainframes. Not as big, powerful, or expensive as mainframes. Less common now because microcomputers have been improved. |
Microcomputers or Personal computers (PCs) | The most common type of computer. Smaller, cheaper, and less powerful than mainframes and minicomputers. |
Type of portable | Notes |
Laptop | About the size of a small typewriter. Less common now because smaller and lighter portables are available. |
Netbook | About the size of a piece of writing paper. The most common type of portable. |
Smartphone | Small enough to fit into the palm of one hand. Not easy to type with because of their size. Often used as personal organizers. |
-
Compare three types of computer.
| Mainframes | Minicomputers | Microcomputers |
Size | +++ | ++ | + |
Power | +++ | ++ | + |

Microcomputers are small enough to sit on a desk. They are the (common) (4) … type of computer. They are usually (powerful) (5) … than minicomputers.
Portable computers are (small) (6) … than desktops. The (large) (7) … portable is a laptop. (Small) (8) … portables, about the size of a piece of writing paper, are called netbook computers. Tablet computers are (small) (9) … than netbooks. You can hold the (small) (10) … computers in one hand. They are called smartphones.
9. Decide what sort of computer is best for each of these users.
-
John Smith spends a lot of time visiting customers. He wants a computer to carry with him so he can access data about his customers and record his sales.
-
Kate Nye is a personnel officer. She needs a computer to keep staff records and to keep a diary of appointments. She also needs a computer for writing letters.
-
The University of the North needs a computer to look after its accounts. Its network, the records of all students and staff, and to help with scientific research.
-
The James family wants a computer for entertainment, writing letters, the Internet, and for calculating tax.
-
I work as a salesperson. I travel a lot and have to keep in touch with my office headquarters. I need to send my colleagues in the office my customers' orders and budgets. I also need a device to organize all my appointments. I don't want to carry much weight.”
10. Translate into Russian.
Let’s compare smartphones and laptops. Smartphones are smaller in size and easier to carry. They weigh less than laptops so they're a better option if you travel a lot and don't want to have a briefcase with you. They fit in a pocket. The batteries in smartphones last longer, which is another advantage for travelers. They are usually cheaper and more versatile.
On the other hand, laptops have a keyboard which is easier to use. The processor and memory are more powerful so working with a laptop is more efficient and faster. They offer the possibility of working with highly-demanding applications (multimedia, graphics, etc.).

Introduction to Computer Software
For as long as there has been computer hardware, there has also been computer software. But what is software? Software is just instructions written by a programmer which tells the computer what to do. Programmers are also known as 'software developers', or just plain 'developers'.
Software programs can have millions of lines of code. If one line doesn't work, the whole program could break! Even the process of starting software goes by many different names in English. Perhaps the most correct technical term is “execute”. Some other common verbs used to start a software program you will hear are “run”, “launch”, and even “boot” (when the software in question is an operating system).
Software normally has both features and bugs. When software has a bug there are a few things that can happen. The program can crash and terminate with a confusing message.
Sometimes when software stops responding you are forced to manually abort the program yourself by pressing some strange combination of keys such as ctrl-alt-delete.
Software programs are normally written and compiled for certain hardware platforms. It is very important that the software is compatible with all the components of the computer. For instance, you cannot run software written for a Windows computer on a Macintosh computer or a Linux computer. Actually, you can, but you need to have special emulation software or a virtual machine installed. Even with this special software installed, it is still normally best to run a program on the kind of computer for which it was intended.
There are two basic kinds of software you need to learn about as an IT professional. The first is closed source or proprietary software, which you are not free to modify and improve. An example of this kind of software is Microsoft Windows or Adobe Photoshop.
The other kind of software is called open source software, which is normally free to use and modify (with some restrictions of course). Examples of this type of software include most popular programming languages, operating systems such as Linux, and thousands of applications such as Mozilla Firefox and Open Office.
But what is the real difference between open source and closed source software? Is open source software just about saving money? Let's investigate. Let's say for instance you find a bug in the latest version of Mozilla Firefox. The bug is causing a major project to fail and you need to fix it right away. This is not very likely to happen, I realize, but it's just an example. You might take the following steps:
Step 1. Download and unzip (or uncompress) the source code from Mozilla.
Step 2. Use an Integrated Development Environment (IDE) and a debugger to find and fix the bug in the source code. Please note that you will need to know a little C++ to debug applications such as this.
Step 3. Test the fix and then use a compiler to turn the source code into a binary file. This can take a long time for big programs. Once the source code is compiled then the program should work!
Step 4. You are almost done. Now send the bug fix back to the Mozilla Firefox team. They may even use your bug fix in the next release!

Learning About Operating Systems
An operating system is a term for the multitasking software that lets you perform a wide range of 'lower level tasks' with your computer. By low-level tasks we mean the ability to:
-
log on with a username and password; -
log off the system and switch users; -
format storage devices and set default levels of file compression; -
install and upgrade device drivers for new hardware; -
install and launch applications such as word processors, games, etc.; -
set file permissions and hidden files; -
terminate misbehaving applications.
A computer would be fairly useless without an OS, so today almost all computers come with an OS preinstalled. Now it is common for an OS to run on many different hardware configurations.
At the heart of an OS is the kernel, which is the lowest level, or core, of the operating system. The kernel is responsible for all the most basic tasks of an OS such as controlling the file systems and device drivers. The only lower-level software than the kernel would be the BIOS, which isn't really a part of the operating system.
The most popular OS today is Microsoft Windows, which has about 85% of the market share for PCs and about 30% of the market share for servers. But there are different types of Windows OSs as well. Each Windows OS is optimized for different users, hardware configurations, and tasks. There are many more operating systems out there besides the various versions of Windows, and each one is optimized to perform some tasks better than others. Solaris, Linux and Mac OS X are some good examples of non-Windows operating systems.
Geeks often install and run more than one OS on a single computer. This is possible with dual-booting or by using a virtual machine. Why? The reasons for this are varied and may include preferring one OS for programming, and another OS for music production, gaming, or accounting work. An OS must have at least one kind of user interface. Today there are two major kinds of user interfaces in use, the command line interface (CLI) and the graphical user interface (GUI). Typically speaking, GUIs are intended for general use and CLIs are intended for use by computer engineers and system administrators. Although some engineers only use GUIs and some geeks still use a CLI even to type an email or a letter.
In recent years, more and more features are being included in the basic GUI OS install, including notepads, sound recorders, web browsers and games. This is another example of the concept of 'convergence'. A great example of an up and coming OS is Ubuntu. Ubuntu is a Linux operating system which is totally free, and ships with nearly every application you will ever need already installed. Even a professional quality office suite is included by default. What's more, thousands of free, ready-to-use applications can be downloaded and installed with a few clicks of the mouse. This is a revolutionary feature in an OS and can save lots of time, not to mention hundreds or even thousands of dollars on a single PC.

Exercise 4. Read the text and make a list of questions to it in writing.
GUI operating systems
The term user interface (UI) refers to the standard procedures that the user follows in order to interact with a computer. In the late 1970s and early 80s, the way users accessed computer systems was very complex. They had to memorize and type a lot of commands just to see the contents of a disk, to copy files or to respond to a single prompt. In fact, it was only experts who used computers, so there was no need for a user-friendly interface.
A GUI makes use of a WIMP environment: windows, icons, menus and pointer. The background of the screen is called the desktop, which contains labeled pictures called icons. These icons represent files or folders. Double-clicking a folder opens a window which contains programs, documents, or more nested folders. When you are in a folder, you can launch a program or document by double-clicking the icon, or you can drag it to another location. When you run a program, your PC opens a window that lets you work with different tools. All the programs have a high level of consistency, with similar toolbars, menu bars, buttons and dialog boxes. A modern OS also provides access to networks and allows multitasking, which means you can run several programs - and do various tasks - at the same time.
The most popular operating systems are:
- The Windows family - designed by Microsoft and used on most PCs. The most recent versions are Windows Vista and Windows 7.
- Mac OS - created by Apple and used on Macintosh computers.
- Unix - a multi-user system, found on mainframes and workstations in corporate installations.
- Linux-open-source software developed under the GNU General Public License. This means anybody can copy its source code, change it and distribute it. It is used in computers, appliances ' and small devices.
- RIM- used on BlackBerry communication devices. Developed by Research In Motion.
- The Symbian OS- used by some phone makers, including Nokia and Siemens.
These computer platforms differ in areas such as device installation, network connectivity or compatibility with application software.

Inside a computer.
IT professionals can divide hardware into two main classes: components and peripherals.
Components are primarily core internal devices of a computer which help define what type a computer is, what it is capable of doing, and how well it is capable of doing it. Nothing affects the overall quality of a computer more than its components.
Components must be compatible with each other in order to function correctly. Certain components can be upgraded to attain increased performance. For example, a video card (or graphics card) can be upgraded to improve the graphics for a CAD/CAM application or 3D gaming experience.
At the heart of the computer lies several key components sitting on the motherboard including the microprocessor: the chipset, RAM and a ROM firmware instruction set called the BIOS. These core components are connected by several "busses" made to carry information around the system and eventually out to display devices and other peripherals.
The CPU is another name for the 'brain' of the computer and normally includes the microprocessor and RAM. This is what does all the calculations. RAM is the memory which allows your computer to hold the operating system and all running programs while your computer is in use. On the contrary, ROM is a kind of permanent memory which is still in tact even when the computer is off. The BIOS is a good example of an application using ROM. The BIOS controls very low-level access to the hardware.
Busses and ports are general terms for connectivity components with connect the different parts of the PC together. These include the serial port, parallel port, PCI and PCIe busses, and the Universal Serial Bus (USB) controller. These devices allow communication between different parts of the system. Also network interface cards are now standard on most motherboards, although USB and PCI versions of the devices are also available.
Your optical drives and hard disk drives are also components in your computer.
The core multimedia components include the sound card and graphics card. They make computing more fun and useful for creative professionals such as designers, gamers, and musicians. Multimedia is definitely a place where high-quality components really matter.
Feeding all these components with a steady supply of energy is another component called the power supply. A low quality power supply can cause havoc in a computer system. On the other hand a bigger than necessary power supply can increase system heat, waste power, and make a lot of noise.
At the most exterior of the computer we see the computer case. This is meant to protect the components, and provide an easy interface to plug in peripherals. If you are buying or building your own computer, make sure it has a good case. Beware of computers with cheap looking plastic cases. If a computer manufacturer uses a cheap case, it's very likely they are also using other cheap components inside as well. Cheap components equal a slow computer which will break after moderate use.
