Digital computers are able to solve issues by processing data in discrete forms.

Key Points

  • The four fundamental functional components of a digital computer system are the Input device, Output device, Main memory and Central Processing Unit. 
  • Central Processing Unit is the brain of the computer. 
  • The Central Processing Unit have Six main Components: 
    • Control unit (CU)
    • Arithmetic logic unit (ALU)
    • Registers
    • Cache
    • Buses
    • Clock
  • All processing for any attached peripheral devices was likewise finished by the central processing unit.

Thus, ALU (Arithmetic-Logic Unit), CU (Control Unit) and Processor Registers are the principal components of the CPU of a computer system. 

Additional Information

  • Solid-State Drive is a non-volatile storage media that stores constant data on solid-state flash memory. 
  • VRAM (Video RAM) is RAM that is used to store image data for a computer display.
