... Author: James Leong Mook Seng Education Officer Control Unit, Memory Unit, and Arithmetic Logic Unit The CPU or Central Processing Unit, is the central part of a computer. Because the CPU performs many different functions, there is a need to divide it up into its components. There are 3 components namely Arithmetic & Logic Unit (ALU), the Control Unit and the Immediate Access Store (known as the IAS or primary memory) ==> Arithmetic Logic Unit (ALU) The ALU is where things are actually done in the processor. 1 It can perform arithmetic calculations on data. For example, it can add two numbers together (in binary) 2. It perform logic decisions to be made on data (If the value is negative then ..., the part of the processor that makes the decision is the ALU). These are computations that involve the use of AND, OR, NOT,>,<,>=,<=,<>, = 3. The third task of the ALU is to act as
