FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the “brains” of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program.

Detailed explanation-2: -The central processing unit (CPU) guides the computer through the various steps of solving a problem. Data enters the computer through an input unit, is processed by the central processing unit, and is then made available to the user through an output unit.

Detailed explanation-3: -central processing unit (CPU), principal part of any digital computer system, generally composed of the main memory, control unit, and arithmetic-logic unit.

Detailed explanation-4: -The actual mathematical operation for each instruction is performed by a combinational logic circuit within the CPU’s processor known as the arithmetic–logic unit or ALU. In general, a CPU executes an instruction by fetching it from memory, using its ALU to perform an operation, and then storing the result to memory.

Detailed explanation-5: -Cache memory is faster than the system RAM, and it is closer to the CPU because it is on the processor chip. The cache provides data storage and instructions to prevent the CPU from waiting for data to be retrieved from RAM.
