Nota Function of the Components of the Motherboard

Central Processing Unit (CPU)

Function :-

A Central Processing Unit or CPU is a microprocessor (or processor for short). It is an integrated circuit chip that is capable of processing electronic signals. The CPU is the most important element in a computer system.

A CPU interprets instructions given by the software and carries out those instructions by processing data and controlling the rest of the computer’s components.

Random Access Memory (RAM)

Function :

• RAM is installed inside computers. RAM is also known as a working memory. 
• The data in RAM can be read (retrieved) or written (stored).
  

  RAM is volatile which means the programs and data in RAM are lost when the computer is powered off.

  
  
  • A computer uses RAM to hold temporary instructions and data needed to complete tasks. This enables the computer's CPU (Central Processing Unit) to access instructions and data stored in the memory very quickly.
  • RAM stores data during and after processing.
   
   

Read Only Memory (ROM)

Function :-

• ROM is another type of memory permanently stored inside the computer.

ROM is non-volatile. It holds the programs and data when the computer is powered off.

• Programs in ROM have been pre-recorded. It can only be stored by the manufacturer; once it is done, it cannot be changed.

• Many complex functions, such as start up operating instructions, translators for high-level languages and operating systems are placed in ROM memory.

• All the contents in ROM can be accessed and read but cannot be changed. 

Expansion Slots

Expansion slots are the sockets where the circuit boards or the adapter cards can be inserted into the motherboard. 

It is a place to fit an expansion card containing the circuitry that provides some specialized capability, such as video acceleration, sound or disk drive control.
