Vocabulary exercises

Exercise 1. Find English equivalents:

Привод, записывать данные, жесткий диск, вмещать, устройство для резервной копии, двухслойный, плотность записи данных, двусторонний, пишущий привод.

Exercise 2. Read the following statements and name the kind of discs. You should choose only from: CD-RW, CD-R, DVD.

• These discs are 'write once' - once they have been written to, the data cannot be erased or changed.

• This disc has two layers for data storing.

• These discs can be rewritten or erased multiple times.

• Multisessions can be created and more data can be added to use this disc more than one time.

• This disc can hold about 4.7 gigabytes.

• This kind of discs is more expensive than two other ones.

Exercise 3. Read the following small text and answer the question: How can we find out the speed our data will be written on the disc?

CD-RW drives will typically have three speed ratings - one for reading discs, one for writing CD-R discs and another for writing CD-RW discs. Speed ratings vary from 1x to 52x, where 1x means that a CD is written/read in 'real time'. For example, a 52 minute audio CD would take about 52 minutes to create at 1x speed, and about 1 minute at 52x speed.

CD-drives have different speeds for any special purpose whether reading or writing discs. The specifications of any drives include the information about these speeds. Just the same situation we have with the discs of any kind. The speed on which it can be read or written is indicated on the surface of the discs.

The data can be written to the disc in a variety of formats to create an audio CD, a data CD, a video CD or a photo CD. The audio CDs should play on most standard audio CD equipment and the video and photo CDs will play on many consumer DVD players.

Read and translate the text Class 3 Components. Peripherals

There are 7 components which allow humans to interface with computers. Three of them you have studied during your previous lessons, they are printers, modems and scanners.

Display devices include computer monitors and other display devices. CRTs and LCDs are common. LCDs are a more recent development, and will replace CRTs as they become more affordable. LCD’s in addition to being lighter also use less energy and generate less heat.

Sound Output includes internal or external speakers and headphones.

Mouse is a user interface device that can enable different kinds of control than a keyboard, particularly in GUIs. Most mice (sometimes the plural is ‘mouses’ to prevent confusion with the rodent) are made from plastic, and may use a ball to track movement, an LED light, or a laser. Today you can get a wireless mouse that allows you to easily give a presentation with out being tied to a desk. And the track ball can be used as just as the optical mouse.

A keyboard is an input device which is connected to a computer and used to type instructions or information into the computer. The keyboards sold have 101 to 106 individual keys. Keyboards differ between languages. Most English-speaking people use what is called a QWERTY layout. This refers to the order of the top row of keys. Some foreign languages (i. e. German) use QWERTZ, where the Z and Y are switched. Many laptop computers do not include a number pad. Modern keyboards sometimes have extra controls such as volume, and keys that can be programmed to bring up programs of the user’s choice. The keyboards hook up to the computer with PS/2 or USB connector.
