Bus Lines In Computer

What is Bus Lines?

It's a electronic communication system. Just like a passenger bus that carries people, the computer bus carries lots of information using numerious electronic pathways called circuit lines.

Now I will discuss about three types of Buses

Data bus.
Address bus.
Control bus.

Control bus Is used to transmit different commands or control signals from one component to another component. Many components are connected to one another through buses. Each component is assigned a unique ID. This ID is called the address of that component.
Address bus carries address of memory location from microprocessor to the main memory.
Data bus is the most common type of bus. It is used to transfer data between different components of computer. The number of lines in data bus affects the speed of data transfer between different components.

System bus in computer architecture

A standard CPU system bus is comprised of a control bus, an address bus and a data bus.
The FSB can range from speeds of 66 MHz, 133 MHz, 100 MHz, 266 MHz, 400 MHz and up.
Most CPU today add a third bus known as an Expansion bus.

Expansion bus Crystal

Is an extension to the external data bus.
The chipset acts as a divider between the two buses, compensating for the speed difference with wait state and special buffering areas.
All integrated circuits must be regulated by a clock crystal.
Every device soldered to the motherboard is designed to run at the speed of the system crystal.
