What makes the mouse especially useful is that it is a very quick way to move around on a screen. The mouse also issues instructions to the computer very quickly. Point to an available option with the cursor, click on the mouse, and the option has been chosen.

People so widely use mice in graphics applications because they can do things that are difficult, if not impossible, to do with keyboard keys. For example, the way you move an image with a mouse is to put the pointer on the object you want to move, press the mouse button and drag the image from one place on the screen to another. When you have the image where you want it, you release the mouse button and the image stays there. Similarly, you use mouse to grab one corner of the image (say a square) and stretches it into another shape (say a rectangle). Both of these actions are so much more difficult to perform with a keyboard that most programs require a mouse.

The buttons on the mouse are used to select items at which the mouse points. You position the pointer on an object on the screen, for example, on a menu or a tool in a paint program, and then you press the button ‘to select’ it. Mice are also used to load documents into a program: you put the pointer on the file name and double-click on the name - that is, you press a mouse button twice in a rapid succession.

1. Translate into Uzbek:Five Types of Printers (1)

Printing is the final stage in creating a document. That is the purpose of the printers joined to your computing equipment. Since the results you can obtain with different types of printers will vary-substantially, here is a guide to help you decide which one is most suitable for your needs. To begin with, it must be taken into account that printers vary in cost, speed, print quality and other factors such as, noise or compatibility. In fact, printing technology is evolving so quickly that there is always a printer for every application or personal requirement.

Daisywheel printers were very common a few years ago. They used a sort of wheel with solid characters which rotated and hammered against the ribbon, but they couldn't print pictures or diagrams, and were very slow and noisy. Dot-matrix printers use pins to print the dots required to shape a character. They print text and graphics and nowadays some of them can print up to 450 characters per second (cps); however, they produce relatively low resolution output — 72 or 144 dots per inch. This level of quality, while suitable for preliminary drafts, is not recommended for reports or books that have a wide audience. They are slower than laser printers but much cheaper.

Five Types of Printers (2)

One common type of non-impact printer is an ink-jet printer. It operates by projecting small ink droplets onto paper to form the required image. This type of printer is quite fast, silent and not so expensive as a laser printer. Nevertheless, you can expect high quality results because The first 32 codes are reserved for characters such as the Return key, Tab, Escape, etc. Each letter of the alphabet, and many symbols (such as punctuation marks), as well as the ten numbers, have ASCII representations. What makes this system powerful is that these codes are standard. Kilobytes, megabytes and gigabytes. In order to avoid astronomical figures and sums in the calculation of bytes we use units such as kilobytes, megabytes and gigabytes. One kilobyte is 1,024 bytes (2¹⁰) and it is represented as KB, or more informally as K. One megabyte is equivalent to 1,024 kilobytes, and one gigabyte is 1,024MB.

We use these units (KB, MB, GB) to describe the RAM memory, the storage capacity of disks and the size of any application or document. For instance, the text of this book contains roughly 1 MB of information.

What we see on the screen is created and stored in an area of RAM, so that there is a memory cell allocated to each pixel. This type of display is ailed bit-mapped. On monochrome monitors, bits 0 are visualized as white dots, and bits 1 as black dots.

On color displays, there are three electron guns at the back of the monitor's tube. Each electron gun shoots out a beam of electrons; there is one beam for each of the three primary colors: red, green and blue. These electrons strike the inside of the screen which is coated with substances called phosphors that glow when struck by electrons. Three different phosphor materials are used - one each for red, green and blue. To create different colors, the intensity of each of the three electron beams is varied. The monitor is controlled by a separate circuit board, known as the display adaptor, which plugs into the motherboard of the computer. Different boards drive different types of displays. For example, the VGA (Video Graphics Array) card has become a standard for color monitors.

Portable computers use a flat Liquid-Crystal Display, instead of a picture tube. An LCD uses a grid of crystals and polarizing filters to show the image. The crystals block the light in different amounts to generate the dots in the image.

THE MOUSE IS THE MAIN PART OF THE SYSTEM

The mouse

The mouse works by sliding it around (ball down) on a flat surface. The mouse does not work if you hold it in the air like a remote control! 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 a 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. Then:

Click - position the mouse pointer over an element and press and release the left mouse button one time.

Double-click - same as above except press the mouse button twice in quick succession without moving the mouse between clicks. It may take a little practice to not twitch the mouse when you first start double-clicking. 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,

An excellent way to practice using the mouse is to play the Solitaire game that comes with Windows.

1. Translate into Uzbek:PartitionMagic

With PartitionMagic, you can quickly and easily create partitions, which act as "file drawers," on your hard disks for storing valuable information such as data files, applications, and operating systems. Storing information in separate partitions helps you organize and protect your data, safely run multiple operating systems, and reclaim wasted disk space.

PartitionMagic enables you to secure your data by physically separating it from other files. Separate partitions also make backups to networks and removable drives easy.

PartitionMagic helps you reliably run multiple operating systems on the same computer. Some versions of PartitionMagic also include BootMagic, a powerful boot manager that helps you safely install new operating systems and lets you choose which operating system you want to use when starting your computer.

Because of limitations with the FAT file system which is DOS, Windows 95, and Windows 98, as much as 40 percent of your hard disk space can be wasted. PartitionMagic reclaims wasted space quickly and safely by using more efficient partition sizes. It can also convert FAT partitions to FAT32 and vice versa.

The United Kingdom of Great Britain and Northern Ireland (1)

The United Kingdom of Great Britain and Northern Ireland (the U.K.) has been the official name of the British Kingdom since 1922. It includes England, Scotland, Wales, Northern Ireland and a number of smaller islands. Other names for the U.K are Great Britain and the British Isles. A poetic name for Britain is Albion. It is an ancient name given to Britain by the Romans. The Romans associated this term with albus, which means white, and identified it with the Dover chalk cliffs.

Not long ago Britain was the home country of a huge colonial empire. Almost 500 million people were subjects of the British Empire. The term the British Commonwealth of Nations was used starting in 1931 to describe the relations between Great Britain and its colonies. Now the days of colonialism are over. The former colonies have become politically independent. But they still have some links with Great Britain. These countries are associated under the British Crown. The British Queen is proclaimed to be the head of state and is represented by a governor general.

The flag of Britain is called the Union Jack. It has the red cross of St. George of England, the white cross of St. Andrew of Scotland and the red cross of St. Patrick of Ireland, all on a blue background.

“God save the Queen/King” is the British national anthem. The words and tune probably date to the 16th century. The tune has also been used for patriotic songs in the USA and Germany.

The British currency is the pound sterling. One pound consists of 100 pence.

DATA (INFORMATION) PROCESSING

The volume and complexity of business and scientific data proces­sing has been growing in the last few decades at an almost spectacu­lar rate, and shows no signs of slacking. Along with the growth in volume of clerical operations, there has been an increased complexity in the management of Business. The commonest solution of this problem in the past was to hire more clerks, but it has often been pointed out that the amount of the paper work has been growing much faster than clerical productivity. Most computer applications are directed towards a combination of paper work reduction and impro­ved management control.

The term «Data processing» encompasses the whole range of ope­rations from input of data to output of results. The word «processing» alone is usually restricted to the operations not included in data origination, rearrangement and output. Processing thus involves the following kind’s operations updating files for inventory receipts and issues; computing gross and net pay making decisions based on quan-titave criteria; estimating sales based on predictions of market beha­viour, etc.

There are a number of functions which must always be carried out in data processing. Whether done by manual, mechanical or elec­tronic methods. 1. Most business information must initially be recor­ded. 2. Information must be stored. 3. Information must usually be processed to put it in more useful form. 4. The processed informa­tion must be made available to the ultimate users. These functions are very general and apply to entirely different data processing sys­tems.
