  THE CENTRAL PROCESSING UNIT (CPU) DEFINITION, COMPONENTS OF CPU- CONTROL UNIT (CU), ARITHMETIC AND LOGIC UNIT (ALU), REGISTERS AND  FUNCTIONS DEFINITION OF THE CPU The Central Processing Unit (CPU) also known as the microchip or the microprocessor (or processor for short) is the electronic circuitry within a computer that carries out the instructions of a computer program. This is the brain or heart of the computer. The main objective of the CPU is to perform mathematical calculations on binary numbers. Most modern CPUs are microprocessors, meaning they are contained on a single integrated circuit (IC) chip. Some computers employ a multi-core processor, which is a single chip containing two or more CPUs called "cores". COMPONENTS OF CPU The major components of the CPU are: 1. Control Units (CU) 2. Arithmetic Logic Unit (ALU) 3. Registers. 4. Cache. 5. Clock. 1.  Control Unit (CU) : This  handles all processor control signals. It directs all input and output fl...

 ALGORITHM AND FLOWCHART 1 -  MEANING, CHARACTERISTICS AND FUNCTIONS MEANING OF ALGORITHM Algorithm can be defined as a set of rules and sequential steps that define how a particular problem can be solved in finite and ordered sequences.  An algorithm is a procedure used for solving a problem or performing a computation. Algorithms act as an exact list of instructions that conduct specified actions step by step in either hardware- or software-based  routines .  Algorithms are widely used throughout all areas of IT.   CHARACTERISTICS OF ALGORITHM 1. They are written in sequence. 2. They are written in English like statements. 3. Finite, it must have a beginning and an end. 4. An Algorithm should be effective  Because each instruction in an algorithm affects the overall process,  it should be adequate. 5. It must be unambiguous ( clear, precise)  and consistent. 6. Input :  An algorithm requires some input values. An algorithm can be ...
