FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -CPU performs all types of data processing operations. It stores data, intermediate results, and instructions (program). It controls the operation of all parts of the computer.

Detailed explanation-2: -Often referred to as the brain and heart of all digital systems, a CPU is responsible for doing all the work. It performs every single action a computer does and executes programs.

Detailed explanation-3: -The clock speed is measured in cycles per second, and one cycle per second is known as 1 hertz. This means that a CPU with a clock speed of 2 gigahertz (GHz) can carry out two thousand million (or two billion) cycles per second. The higher the clock speed a CPU has, the faster it can process instructions.

Detailed explanation-4: -The four primary functions of a processor are fetch, decode, execute and write back. Fetch-is the operation which receives instructions from program memory from a systems RAM. Execute-is where the operation is performed.

Detailed explanation-5: -At a time, an 8-bit CPU can process 8 bits of data. Depending on the type of microcomputer, the word length might range from 4 to 64 bits. The largest amount of data that a processor’s accumulator/working register can handle at a given time instant is the data bus width.
