Nowadays, everyone needs to wear a computer to do any work or find information. It does not matter any normal laptop or computer, everyone needs to have a computer. Therefore, we will see important parts of computers and need to be known to everyone. This knowledge can help the public to know good actions if there are computer parts that are damaged or unusable.
5 important components
A computer must have 5 major components to complement its system so that it can work and can join the effectiveness of its use. With these components, the compilers can function properly and run smoothly.
1) Monitor ( Display)
- A type of output peripheral device capable of displaying characters and / or images, both silent or moving, generated by the computer and processed by the graphics card.
- Tedat four types of monitors, monitor monitors, color monitors, multiple synchronous monitors, and ELD monitors (Electro LumineScent Display).
- Showing the results of processes from computers in the form of text, pictures, or videos visually.
- Devices displaying data or information.
2) CPU (system unit)
- CPU is a hardware that has a large part in computer system operations.
- Hardware connected to the monitor screen to get the system command.
- To process all calculations, instructions and perform arithmetic and logical operations of data taken from memory or from information entered through other hardware to support computer operations.
- Carry out programs stored in the main memory by translating instructions to implement it one by one according to the order flow.
- Contains components such as Central Processing Unit-CPU, Master Board, Memory, Power Resources and Storage.
- As a "computer brain".
3) Keyboard
- Have a modest function, ie implement data in the form of numbers, letters, and symbols pressed for its users.
- Works to send orders that have been typed by users who then reach CPU (Central Processing Unit), then the order will be a digital signal that will eventually be captured by the processor.
- The main tapboard which contains the alphabet letters from A to Z, then there is a punctuation, and the figures from 1 - 0 used by the user to tap the text into the same computer on MicroSFT Word or others.
- The device used to enter data and instructions into the computer.
4) Mouse
- Input device to a computer that works to control the indicator or cursor movement on the display screen.
- Facilitate a user to handle animated software, graphics, and table publishing programs.
- When the mouse is moved, the indicator on the display screen will move in the same direction and it will change according to the location where the mouse is located.
- Used to give instructions to the computer.
5) Speaker
- Works to manufacture process results from CPU in the form of voice or audio.
- Computer speakers have a very diverse shape, some have a small, medium size or large size. The power to make sounds also varies depending on the voltage amount used.
- Tool to convert an electrical wave originally from an audio amplifier device or sound into the vibration wave in the form of a joint sound.
- The speakers will make the sound played on the computer either from the music player or video sound.
