Detailed explanation-1: -In computer architecture, a bus (shortened form of the Latin omnibus, and historically also called data highway or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)
Detailed explanation-2: -There are three types of bus lines: Data bus, Address bus, and Control bus. Communication over each bus line is performed in cooperation with another. The data bus is a signal line for exchanging the data between the CPU and the memory, and between the CPU and I/O, and handles the data stored in the specified location.
Detailed explanation-3: -The Motherboard Your computer’s brain is the CPU: that’s where all of the programming and computing happens. But its nervous system is the motherboard, which uses circuits to connect the CPU to the other pieces of hardware, including the memory, the hard drive, the CD/DVD drive, and all of your peripherals.
Detailed explanation-4: -An 8-bit bus carries data along 8 parallel lines. A 16-bit bus, also called ISA (Industry Standard Architecture), carries data along 16 lines. A 32-bit bus, classified as EISA (Enhanced Industry Standard Architecture) or MCA (Micro Channel Architecture), can carry data along 32 lines.
Detailed explanation-5: -The FSB (front side bus) connects the CPU to the motherboard components. The FSB is considered the speed of the motherboard.
