NT1110: Computer Structure and Logic Components of motherboards: The CPU (Central Processing Unit) component of the computer acts as the brain which is responsible for decoding, fetching and executing program instructions. The motherboard contains two major buses, the system bus and the I/O bus. These buses carry all the information between different parts of the computer. The motherboard also has memory slots which temporarily stores data when working on computers, it also increases computer’s total resources. The motherboard also has expansion slots most commonly used by audio and video cards, although the slots can be utilized by many other types of cards. You also find mass storage ports for hard drives, CD-ROMs, and DVD-ROMs on the motherboard. Functions of motherboards: The motherboard is where all the major component of the computer is held. It is the central meeting point of all technologies in the computer. It serves as a circuit board that connects and communicates to all devices and components attached to it. It also provides connection to various parts of the computer and helps them work together. Importance of System Bus and I/O Bus The data bus portion of the system bus carries information between RAM and the CPU. Wider data buses enable more “lanes” of data to flow at the same time promote faster system performance. The power lines in the system bus transfer power from the motherboard’s connection to the power supply to the integrated circuits (ICs or chips) and expansion boards connected to the motherboard. The control lines in the system bus controls the transmission and movement of information between devices connected to the motherboard. The address bus is used to “pick up” information from the correct memory location among the gigabytes of RAM in computer systems and “deliver” new programs and changes to the
