Some major CPU brands are Intel, AMD, and Cyrix.

 

The average price of a CPU is about 100- 1000.

 

CPU- Central Processing Unit

 The central Processing Unit is the brain of the computer, without it there is no computer. It has a thousand transistors.

  • Transistors are tiny microscopic pieces of material.
  • It blocks weak charges of energy but leys in strong charges of energy.

Modern CPU's are called integrated chips.

CPU Components

  • Execution Core
  • Data Bus
  • Address Bus
  • Math co-processor
  • Instruction sets/Microcode
  • Multimedia extensions
  • Registers
  • Flags
  • Piplining
  • Memory Controller
  • Cache Memory  

 

RAM- Random access memory

 The RAM is the storage location of a computer. It also has the memory of the computer. The memory can be eased when the computer is turned off. Its easier to access data in a computer then a hard drive.

 The two different types of RAMs are dynamic RAM and Static RAM. 

 

Some major RAM brands are Crucial, G. Skill, Kingston Value RAM. The price ranges for PAMs are around $20- $100.

 

Mother board

The mother board is the center of the computer system.  The mother board contains controllers for electrical devices such as hard drives. DVD's, Keyboard and mouse. It also contains chipsets which are a collection of chips. The mother board is attached to the CPU, ROM, memory RAM expansion slots, PCI slots, and USB ports. Its can also be called main circuit board, main board or logic board.

 

The speed of a motherboard is maximum FSB(Front Side Bus) Speed.

 

The price range for a mother board is about $80- over $100.

 

Some motherboard brands are Dell, Acer, AMD, Lexar, and Foxconn.
