 What is Internal Communication?

INTERNAL COMMUNICATION:

Although the computer is an electronic device all the communication are done electronically signal, so there are required some wire form electronically pulses. Digital code of information inside the computer one unit to another.

CPU of the computer system communicates with the memory and the I/O devices in order to transfer data between them. The method of communication of the CPU with memory and I/O devices in different. 

The CPU may communicate with the memory either directly or through the Cache memory. 

What is BUSSES?

BUSSES:

In computing, is a set of physical connection (capable, printed circuits) which can share by multiple hardware components in order to communicate with one another is called busses. 

There are three types of busses given bellow👇 

1.   Address Busses
2.   Control Busses
3.   Data Busses

 

 

 ADDRESS BUSSES:

Each I/O unit of the computer system is given an address and each information location in memory is given an address, by the wires which carry those types of signals is called address busses.

In order to perform the memory read or write operation from the main memory RAM, the CPU sends either read or write control signal on the control bus and address of the memory location along the Address Bus from where the operation is to be performed.

CONTROL BUSSES:

Other digital cords representing control are send on the control busses to tell the memory what to do either to read or write going on the memory from CPU tom be right memory location is called control busses.

The control bus is a part of  system Bus in addition to Data bus and Address Bus.

DATA  BUSSES:

The information coming to the CPU from the memory is read or going to the memory from the memory location is called data busses.

The width of a Data Bus refers to the number of bits(electrical wires) that the bus can carry at a time. A 16 Bit wide data bus can carry 16 bits of data simultaneously between the CPU and the system component such as main memory RAM.
