Computer Architecture

Computers can be divided into External Components and Internal Hardware.

Computer Consist of 3 main items

• CPU
• Main Memory
• Input and Output

This is called Neumann Architecture

Processor

 This Is responsible for  executing and supervising the functions of the other parts of the system.

Main Memory aka Immediate Access Store(IAS)

It can be divided into 2

RAM and ROM

Simplest part of the computer

This is where all the data is stored and this data is stored onto a  byte which can be referred to as a memory location.

RAM

Random Access Memory

Data Stored on this memory is Volatile which means that any data stored on this section of the memory is wiped when the power is switched off

ROM

Read Only Memory 

Data Stored on this Section does the opposite to what RAM does it stores the data and does not wipe it 

Another Type of memory is 

EEPROM

Electrically Erasable Programmable Read only Memory

It does not allow the content to be altered
