Vocabulary exercises

Exercise 1. Find English equivalents:

Оперативная память, постоянная (которую нельзя изменить) память, материнская плата, системный блок, временная память, выключение питания, слот расширения, терять данные, обеспечивать дополнительные функции, снижать энергопотребление.

Exercise 2. Match the following terms with thier explanations.

1. Core

2. Core Duo processor

3. Hyper Treading

a) The more powerful processor. Two cores increases the data flow into the processor and the command flow out of the processor doubling the processing power.

b) It is a technology that uses one core but adds a virtual processor to an additional thread (цепочка выполняемых задач) at the same time.

c) The place where the data is processed and turned into commands directed at the rest of the computer.

Exercise 3. Try to guess what kinds of computer components we speak about.

• Some may argue that this component is the most important part of a computer, because it provides computer with needed energy.

• It carries the CPU.

• This is a cover for almost all the components that are integral to the function of the computer.

• It is the so-called ‘brain’ of computer.

• It is the place where the data we are working with is stored for a while.

• Exercise IV. Guess whether the following statements are right or wrong. Try to explain your choice.

• All the MBs have LAN controller, onboard sound and graphics.

• The motherboard keeps an embedded RAM.

• When a software application is launched, the executable program is loaded from hard drive to the RAM.

• All the content you are working with will be lost at power-down.

Exercise 4. Discuss with your group-mates the following statements. Try to prove your point of view.

1. The power supply is one of the most important components, that’s why it is worth spending the money to get a good one.

2. The expansion slots (PCI, AGP, ISA, etc.) allow additional functions.

3. UPS can prevent your from the data loss at power-down.

Read and translate the text Class 2 Components. Storage

Sometimes one can distinguish between "fixed media" (the hard drive) that is more or less permanently mounted inside the computer case, and "removable media" (just about every other kind of media) that is easy to pull from one computer and put into another computer.

Floppy Disk drives. The first 8-inch floppy disk design was invented in the late 1960s by IBM, but these floppies were used only by a very limited group of people. Some time later 5.25" floppy disc was introduced and used in the 1980s. And only 3.5" floppies are supposed to be the most commonly used storage media. They hold from 400KB up to 1.44 MB. Floppy disks have largely been superseded by flash drives as a transfer medium, but are used as backup storage in our country. At the beginning of 2006 it was announced that all the floppy manufacturers would stop to produce such a product.

A hard drive (often called HDD) consists of one or more magnetic disks and a read arm with two electromagnetic coils for each disk. Each hard disk is divided into many sectors, each containing a certain amount of data. It is the cheapest and most common way to store a lot of data in a small space.

CD-ROM drive is a standard format for storing a variety of data. A CD-ROM holds about 700 MB of data. The media look like a small, somewhat flexible plastic disc. Any scratch or abrasion on the data side of the disc can lead to it being unreadable.

CD-RW drive supports the creation of CD-R and CD-RW discs, and also function as CD-ROM drives. These drives use low-powered lasers to 'burn' data into the active layer of the disc. Many CD writers (also known as 'burners') are now combination drives which also function as DVD-ROM drives. Most DVD-RW drives also have CD-RW capabilities.

DVD-ROM drive. This optical drives work on a similar principle to the CD-ROM, with a laser being used to read data stored in pits on the surface of a reflective disk. DVDs are read using a shorter wavelength of light. Besides a greater data-density, DVDs may be double sided and may be "dual layer".

DVD-RW drive works with DVD-discs and dual-layer disks (dual layer equipment and disks are now becoming more affordable).
