2. Computer is a general-purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

3. Monitor is a device intended for visual display of information. Modern Monitor consists of a housing, power supply, motherboard and screen control. Information (video) to output to the monitor comes with the computer via a video card or other device that forms the video signal

4. Motherboard - a complex multi-layer printed circuit board, which sets out the basic components of a personal computer or an entry- level server (CPU, memory controller and the actual memory, boot ROM, controllers, basic input-output interfaces). That motherboard integrates and coordinates the work of such diverse in nature and functionality of components as CPU, memory, expansion cards, and all kinds of drives.

5.  The Central Processing Unit (CPU, or central processing unit - CPU, Eng. Central processing unit, for short - CPU, literally - central processing unit) is an electronic module or chip - singer machine instructions (program code), the main part of the computer hardware or a programmable logic controller. Sometimes referred to as a microprocessor or simply processor. Originally, the term central processing unit describes a specialized class of logic machines designed to perform complex computer programs. Due to a fairly exact match of the destination features then existing computer processors, it was naturally transferred to the computers themselves

6. AT Attachment is a parallel connection of storage devices (hard drives and optical drives)to your computer

7. Memory is a part of the volatile computer memory, which, as the name suggests, temporarily stores data and commands necessary for the performance of the processor operation. It is imperative addressability (each machine word has an individual address)of memory

8.  Video Card is a device that converts an image that is in the computer's memory into a video signal to the monitor. Modern graphics cards are not limited to simply finding images. They have a graphics microprocessor that can perform additional processing load off the CPU

9.  Sound card - an expansion card that converts audio from analog to digital. Main opportunity to sound card - digital audio and video files stored on your computer. Audio Adapter allows you to record sound, play it, contains the ADC, DAC and digital signal processor, which performs calculations. Professional sound cards allow you to perform complex processing of sound, have their own ROM

10. Network Interface Card is an expansion card that allows a PC to communicate with other devices on the network (currently integrated on the motherboard). AC adapter, along with his driver performs two functions: receiving and transmitting the frame. In the client PC is usually a considerable part of the work shifted to the driver that allows to reduce the cost of the adapter, but the CPU load. Adapters are designed for servers, usually have their own processors, which perform most of the work on the transfer of frames from memory to the network and vice versa

11. Computer power supply is a secondary power source (power supply unit, PSU), intended to supply the host computer's electrical power DC and AC voltage conversion to specified values

12. Disk drive is computer device that allows you to implement read / written information to the media. The main purpose of the drive, under the concept of memory hierarchy is the organization of long-term memory. The main characteristic of the drive is the amount of disk space (memory), measured in bytes

13. The hard disk drive or hard drive, hard disk, in computer lingo "hard drive" is a storage device (storage device) of random access based on the principle of magnetic recording. Is the main storage of data in most computers

14. The standard computer keyboard, the keyboard also known as PC / AT or AT- keyboard (since it is supplied with the beginning of a series of computers, IBM PC / AT), has 101 or 102 keys. Keyboard that shipped with the previous series - IBM PC and IBM PC / XT, - had 86 keys. [Citation needed 964 days] The key layout on the AT- keyboard submits a single common scheme designed based on the English alphabet

15. Manipulator "mouse" - a mechanical arm, which converts mechanical motion into cursor movement on the screen

16. 1. Computer 2. Manipulator "mouse“ 3. The hard disk drive 4. Computer power supply A. a mechanical arm, which converts mechanical motion int o cursor movement on the screen B. a general-purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem C. a secondary power source (power supply unit, PSU), intended to supply the host computer's electrical power DC and AC voltage conversi on to specified values D. a storage device (storage device) of random access based on the principle of magnetic recording.
