      In Relation to A Computer, What Do the Letters CPU Stand For?

      CPU stands for the central processing unit. It is part of every digital computer system. It is composed of the control unit, main memory, and arithmetic-logic unit. It’s also called the central heart of the entire computer system because it is interconnected to outer equipment like input, output devices, and additional storage units. With the advancement in technology, central processing units in modern computer systems contain microprocessors like (ICC) Integrated circuit chips.

      Composition of the central processing unit:

      With time designs, forms, and applications of CPU change but their basic operation remains unchanged. The main components include (ALU) arithmetic logic unit that performs functions like logic and arithmetic operations, processor register that store the results of arithmetic logic unit. The Control unit organizes the fetching from memory. In the modern system, it contains a microprocessor chip with many CPUs are called a multi-core processor. The processor core of individual CPUs can also be multiprocessor to create additional logical CPUs. Multiple processors that run in parallel with no central unit are called vector or array processors.

      Operation of CPU:

      The basic operation of most of the CPUs is to execute the stored information called program. The information or instruction that can be executed is stored in memory. The term instruction cycle is used in all central processing units because all CPUs can fetch, decode and execute steps during their operation. The whole process repeats after the execution of the next instruction cycle fetch the next sequential instruction. Steps for the operation of the central processing unit are.

      • Fetch
      • Decode
      • execution

      The function of the Central processing unit:

      These are the following function of the central processing unit as given below

      • The operation of the computer regulates and combine or integrate by the control unit of the central processing unit.
      • From the main memory, the CPU selects and rectifies the information’s in proper sequence and explains it, and switches on the other operational elements of the system at the correct time to perform their operations respectively.
      • For processing, all the input information is transferred to the arithmetic-logic unit by the main memory. The four basic units of arithmetic functions are
      1. Addition
      2. Substruction
      3. Division
      4. Multiplication
      • A logic operation like comparison of data and selection of procedure for solving the desired problem or a feasible alternative depends on fixed criteria.
