Five Basic Block Diagram Of Digital Computers
Computers that we have now today are perfectly designed as digital or called digital computers. Because of the digital computer our environment changes through digital computing. The most common purpose is data processing. Government, Industries, and business use computers to preserve records, perform accounting tasks, keep and track the records of inventory, and provide a widely diversity of other data processing functions.


Talking with the invention of digital computers, these are consisting of five basic block diagram or sectors. They are control, arithmetic logic unit abbreviated as ALU, memory, input and output unit. This input and output blocks are a single block, we called as I/O or input and output unit. Or referring to the devices of computers connected externally to the CPU. Precisely, the control unit and the arithmetic logic unit are intimately associated and cannot be separated. Therefore, they are collectively called as the Central Processing Unit, the chip or the microchip that we called as the process or the Micro Processor Unit (MPU). (see the image shown above of this post)

  1. Control Unit- this is the device or a part of computer responsibly or performs such regulating functions. A memory controller chip, for example, is the controller to access the computer’s memory. Therefore, it is the controlling unit of that memory.
  2. Arithmetic Logic Unit- this is the part or a circuitry of the Microprocessor chip for arithmetic operations, proportional and related functions, and logical functions. The common term that the processor's ability of the system of the computer is to fetch, decode, and execute the data.
  3. Memory- this is a part of a computer or a card or modules that inserted into the motherboard’s slot. This is a circuit that allows the information to be stored and retrieved. In other functions, it also refers to the disk drives that stored permanently, the information or the data.
  4. Input Devices- this refers to the devices of computers that externally connected to the System Unit that the system of computer feeds or decode first the data before to display using the output devices of a computer.
  5. Output Devices- this refers to the devices of computer that have an ability to display the information or can produce a hardcopy of a document. The main output device of the computer, example is the monitor or the display screen, that commonly called as Cathode Ray Tube (CRT), Liquid Crystal Display (CRT), and the new LED or the light emitting diode that the fluorescent lamp inside the LCD panel was replaced by an LED light.
That’s it!
