System bus
System buses in computer are use to connect the measure component of a computer system.Information caries by data bus and address bus determine where it should be sent and a control bus to control it's operation. Simply we can say that buses are used in computer to connect it's components and transfer data between them. Buses may be serial or parallel. Parallel buses transfer data across multiple wires and serial buses transmitted data in single wires. System bus is a cable which capable of carrying signals from one place to another place a computer bus can be divided into two different types : Internal and External .
Internal bus connect the different component inside the cabin-ate for example CPU and all other components on the motherboard.
The external bus connect the different external devices peripherals, extension slots, input output codes etc.
Types of bus :
1. Address bus : A collection of wires used to identify particular information in main memory is called address bus. Address bus is also known as memory bus.
2. Data bus : Lines that carry data to and from memory are called data bus. The main work of the data bus is to carry digital information.
3. Control bus : A control bus is carries the control signal that make sour everything is flowing smoothly from one place to another.
