Five Basic Block Diagram of Digital Computer

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!

Basic Operation of Computer and its General Functions

Computer design with the composition of hardware and software, therefore we need to understand the basic operations how the computer works of the system. Through the logic of both the hardware and software. It’s understood that we need to apply care to our computer unit. We should understand and identify how to use it. And how it works after you press the power button on the computer monitor and the power button on the front panel of the system unit of the computer. Remember, if we don’t know how to use our computer, it’s understood that you will contribute error to the system. And through this, it will bring serious damage of both the hardware and software of the computer.

This lesson is the most basic at all, we do this always once we use the computer. This would mostly apply to the beginner of the computer and those other users that didn't know how to operate the computer properly.

  1. POWER UP SYSTEM- This involved with turning on the computer properly, which of the devices turning on first. We know that there are plenty of hardware or peripherals connected to the system unit. They are monitor screen, system unit (CPU), printer, speaker, and scanner. And this computer may connect to the AVR (Auto Voltage Regulator) or a UPS (Interrupted Power Supply). Just turn on first the AVR or UPS and turn on the monitor screen and then turn the CPU (Central Processing Unit) on.
  2. SELF TEST- After turning on the computer properly, the computer will conduct a Power On Self Test(POST) at around 5 seconds depending on the amount of the memory. This POST through the BIOS(Basic Input Output System) will check the condition of the main hardware connected internally, such as the HDD(Hard Disk Drive, CD/DVD ROM, RAM capacity, Processor) and the keyboard. And responsible in mounted or loading up the operating system’s startup file through the first boot of the BIOS. And if there are failure of the main hardware or such the HDD it will halt on then it will display on the POST information (Display).
  3. LOAD PROGRAM DISK- Once the POST is successful, the computer will load the Operating System (OS) and initialize all the peripherals and device driver connected to the CPU. In this operation there are tendencies the computer will create a serious error such as BSOD (Blue Screen Of Death). This error commonly causes by the processor overheat or the failure of the OS startup files during bootup. Or cause by a virus loaded in the OS startup files. When this occurs, your computer subject for repair.
  4. USE PROGRAM COMMANDS- When the POST is successful and the OS is normal you can press F8 during bootup of the OS. It will bring you to the Advance Menu of the computer OS. And you can select either Run in command mode, so that you can use the MS-DOS (Microsoft Disk Operating System) and either you can run the recovery files or run the diagnostic and repair command of the computer. This you need a knowledge in using the DOS command line on the computer both internal and external command.
  5. KEYBOARD AND VIDEO MONITOR SCREEN- Running the computer both windows environment and MS-DOS you should have enough knowledge using the 5 major functions of the keyboard. Because the keyboard use to enter commands in the computer and the CPU will response on the monitor screen. The 5 major function of the keyboard are:
      • Function keys
      • Alphanumeric Character
      • Special Keys
      • Cursor Keys
      • Numeric keypad
    • Composition of the Alphanumeric Character
      • Letters
      • Numbers
      • Punctuations
      • Symbols
      • Special Keys
  6. GET/SAVE FILES- This operation of the computer used to retrieve and save files on the disk both the target and source procedure. This involve with the HDD, USB flash drive. That you can use it to retrieve large amount files or not. You can save or retrieve the files on a compact disk or DVD because the memory on this are read only. Either you can use a software, example NERO so that you can write it in the compact disk or DVD.
  7. PRINTOUTS-  This is to provide a hard copy of the document, using your printer either a DOT metrics or a colored printer.
  8. SHUTDOWN OR TURN OFF PC- When your computer is unattended or not use, just shut down or turn off the PC. Don’t forget to turn off the monitor screen and other peripherals and also turn off the AVR. If you are using UPS turn it off to prolong the lifespan of the battery backup inside of your UPS.

Most Common Parts Inside the Computer System Unit

System Unit

SYSTEM UNIT OR CPU Under the three fundamental devices of the computer as one unit, they are input devices, output devices, and the System Unit. System Unit or CPU (Central Processing Unit). Act as the main device of the computer which controlled the main processing of the computer that accepts signal coming from both input/output devices. And those devices of the computer externally connected to the CPU. And processing it according to its series of instructions through the logical program. Therefore, inside of this System Unit, there is hardware installed and connected together to perform the processing of the instructions (Data) of both different applications of the program.

I collected different pictures of the hardware and I posted them here in this post below. Just study this in order to familiar this hardware and let you know the inside of the System Unit.

Motherboard or MOBO

MOTHERBOARD or MOBO- act as the main assembly of a computer mounted a variety of chips. It is a hardware of computer task to hold and control other hardware inside the System Unit both Input/Output devices. The hardware is the processor, memory card or RAM, Video Card or VGA (PCI, AGP, PCI ‘e), CMOS/BIOS battery, Power Supply Unit(PSU), Hard Disk Drive(HDD) SATA or PATA, CD/DVD ROM, WIFI card, LAN Card, Cooling System (Air Block), Sound Card, Internal Modem Card, and USB card. The motherboard has a different form factor according to its generation through processor type. Such as the ATX Socket 775 of Dual Core and Core2duo processor, Socket 478 of Intel P4 1.5- 2.0, AM2 of AMD processor Sempron 64 and Athlon, and the Obsolete Motherboard Slot I and II and the Socket 370 of Pentium 3 processor.
