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.

Memory Management Paper POS355 Jun 2nd, 2014 Memory Management Paper With each passing day computers are becoming more and more important to the world around us. Computers allow people to perform many tasks that once used to be much more difficult, and even allows a user to perform many tasks at once. When computers are running multiple programs at a time it is important that memory is allocated in a way that accommodates all of the processes that are involved. This concept of allocation and division is known as memory management and is comprised of five key requirements which are relocation, protection, sharing, logical organization, and physical organization. Today we will be examining these five requirements and why they are important.
