Setting Up or Customizing a Computer

When a Computer Arrives
What shpul;d be done before using a new computer? This depends very much on where the computer came from and what software was alread installed. If a computer project receives new computer complete with an operating system and all prodectivity software, little needs to be done before using the computer. The computer lab manager should check, however, to make sure the computer is fully set up to meet the needs of the project. Some items to investigate are listed here:

• Does the computer already have all of the programs that are desired for the project? Thuis could include, for example, an internet browser, productivity (pffice) software, antivirus software or perhaps some educational software.
• Does the computer already have all the files that are desired for the project? For example, an educational project might want to have an encyclopedia or same educational loaded on all of the computers.
• Does the computer have user accounts with password? This is a good way to control what access some users have to particular programs, files or setting and many more things.....

A system unit has several important sub-components

•System Board

•Central Processing Unit

•Memory

•System Bus

•Storage Devices

•Power Supply

•Cooling Systems

•Adapter Cards

•Riser Cards

 

 

The system board is the personal computer component that acts as the backbone for the entire computer system.

 

 

Memory is the personal computer component that comprises the electronic storage areas in the  computer.
Memory can be considered either volatile or non-volatile.

 

 

The system bus is the main communication path between the  CPU and memory.

A storage device is a system unit component, such as a hard drive that enables users to save data for reuse at a later time, even after the personal computer is shut down and restarted.

A power supply is an internal  computer component that convert AC power from an electrical outlet to the DC power needed by system components.

• A cooling system is a system unit component that prevents damage to computer parts by dissipating the heat generated inside a computer chassis.

Computer system contain the following components that require cooling:  

          

          ØThe CPU

          ØThe Power Supply

          ØSome Adapter Cards

          ØSome Hard Disk Drives
