System Architecture

There are several parts to a computer. Each part works together to allow the computer to function properly. If one part of the computer is not working properly, the entire computer is likely not to function to the best of its ability. This essay will explain the function and purpose of the CPU, memory, bus, cache, address registers data movement instructions and multiprocessing. The essay will also explain how these components interact with one another.

The Central Processing Unit (CPU) is the brain of the computer. It is where all of the computers processing takes place. Without the CPU, the computer would not function at all. Overall, the CPU tells the other components what to do and when to complete these functions. The CPU consists of two parts; the Arithmetic/Logic Unit (ALU) and the Control Unit (CU). The ALU is where all arithmetic and logical executions are completed. For instance, all mathematical operations such as addition, subtraction, multiplication and division is taken place in the ALU (How Computers Work, 2012). On the logical spectrum of the ALU, it can perform comparison on data such as letters and numbers (How Computers Work, 2012). Comparisons in the ALU consist of equal to, greater than or less than. The other component of the CPU is the CU. The CU is responsible for directing the computer to execute stored functions (How Computers Work, 2012). The CU works hand in hand with the ALU and memory to ensure the computer functions properly. Overall, the components of the CPU are important for proper function of any computer. Without the CPU, the computer would not function.

The next journey inside of the computer is the register. The register is simply a permanent storage location for...
