1. Computer generation and their classification Computer architecture and working principles

4. Computer fundamental and around the device and their characteristics

The present time at the computers in all spheres of development great contribution methodology’shmoqda. This is why your computer, from use to many users programming, algorithm language faster adopters trying are. Dynamic surstlar with developing and growing science and technique in front standing issues of the solution in very large is out come and them just computers using calculate that the users understanding of the reach.
Personal computers (Sh -K) , mainly following the main device up and finds:

• 
  systematic block (the processor, the memory, mikroprotsessor, adapters located in is, output device (monitor);
  
• 
  input device (keyboard, mouse);
  
• 
  The monitor (display, screen) - user text and graphics data production for serve will.
  

The computer with which direct communication on the screen, see to monitor service will. Monitor two: monochrome and colour types available, become, them video adapter device in the management of two different mode, text or graphics position in one of they work. They from each other in size with differ. Text mode monitor screen is conditional on the basis of 80 than superior, to 25 bar is. The same area is voluntary in the place the characters are described. This of characters large and small Latin letters, numbers , and auxiliary characters be can. Graphics mode screen text information in addition to pictures and graphic images also are removed. This character is optional font and size able be. In this mode, the on-screen dots (pixels) from the collection is. For example, 640 x 400 imkoniyatli monitor screen to horizontal 640, vertical to 400 point describes. Dots is the number of an increase in the with the image quality will increase. VGA Color 80x25, units, 16 color 640x480, 16 color units, mwf to Color 80x25, 16 color units 800x600, 256 color units to the computer monitor to connect to special videoadapter needed.
