20 Kinds of Computer Hardware and its definition

On this occasion, I will review the understanding and assorted computer hardware or hardware.
Computer itself has been used by many people. Physically, the computer also has components called hardware.
In the computer world, the understanding of the hardware or the hardware is the physical components that make up a computer system.
Hardware themselves have different properties with software that can be seen, touched and shaped real. The types of hardware on the computer is not only focused on the inside of the computer only, but any device that supports the computer's performance.
Various Kinds of Computer Hardware
1. Motherboard

The motherboard is the circuit board that serves as the computer components such as processor, hard drive, RAM and others. The motherboard itself in the form of a main board PCB-shaped and has a BIOS chip, lines and connectors that serves to connect each device.
2. Processor

Processor is an IC that controls the entire operations of a computer system. Processor or CPU (Central Processing Unit) can be regarded as the brains of a computer, as well as commanding duty calculating program that will be run by a computer.
3. Hard Disk

Hard disk or hard disk drive (HDD) is a computer hardware that serves as a storage medium. In a hard disk, there are more than one dish which serves to enlarge the capacity of data that can be accommodated by the hard disk.
4. PC Cooler / Heatsink

PC cooler / heatsink is a computer device that serves to reduce the heat generated by the computer. Given the heat on a computer can damage other hardware in it, then the role of the PC cooler / heatsink is essential.
5. Monitor

Monitor is one of the hardware that is classified as an output device which display the results of data processing in the form of graphics. Each brand has a monitor sizes and resolutions vary. The types of monitors are most common today is a CRT (Cathode Ray Tube) monitors and LCD (Liquid Crystal Display).
6. SSD

SSD or Solid State Drive is the latest innovation from its predecessor the hard disk. SSD is a storage medium that uses a type of solid state memory for data storage. SSD also has the same function as a hard disk, but a little different from the hard disk.

The data on the SSD is stored on-chip flash memory chips are connected. These chips have the speed and reliability higher than USB Thumb Drive (UFD). In terms of pricing, SSDs are more expensive than HDD although with the same capacity.
7. VGA Card

VGA or Video Graphics Adapter is a hardware device that functions to process data graphics to be displayed by the monitor. VGA also has a processor which is called GPU (Graphic Processing Unit). Typically the hardware is sorely needed, especially for gamers and designers.
8. Optical Drive

Optical drives are one atu hardware that serves to read (read) and write (write) data from CDs / DVDs. There are several types of optical drive that you need to know, such as: CD ROM drive, CD RW drive, DVD ROM drive and others.
9. Power Supply

Power Supply is hardware that functions as a power supply to other components such as motherboard, processor, VGA, etc. Power supply is arguably the heart of the computer, so the computer is impossible to live without this device.
10. RAM

RAM or Random Access Memory is the hardware that hold data and instructions performed by the processor. In contrast to the hard disk, storage in RAM is temporary. So when the computer is turned off, the data and instructions stored by RAM is lost / emptied except the computer in hibernate mode.
11. Keyboard

The keyboard is a key plank classified as input devices. The keyboard itself consists of a row of letters and numbers. There are different types of keyboards, among others: QWERTY keyboard, the Dvorak keyboard, keyboard KLOCKENBERG, Maltron keyboard, keyboard alphabetik, and Numeric keyboard.
12. Mouse

As with the keyboard, the mouse is also classified as input devices. Mouse function moves the cursor or refer the application to run. This device is called a mouse, because its shape resembles a mouse. There are many types of mouse, among other things: a serial mouse, PS2 mouse, USB mouse and wireless mouse.
13. Printer

Similarly, monitor, printer hardware is classified as a tool output. Printer function to print the data processing in the form of text / image on paper (hard copy). Based on the technology used today, the types of printers that were encountered are Dotmatrix printer, Inkjet printer and Laserjet printers.
14. Sound Card

Sound Card is a hardware device that functions to process data in the form of audio or voice. At first, only a complement to the computer sound card, but this time the sound card is a device that must be owned by the user of the computer.
15. Scanner

Scanner is a hardware that has a way of working that is almost the same as photocopying. In contrast to the workings of the copier, scanner function to change the hard file into digital files that can be processed in a computer.
16. LCD Projector

LCD projector is one type of projector that is usually used to display video and pictures from a computer on a screen or on a field that has a flat surface. To view a video / picture, LCD projectors send light from the metal halide and then forwarded to the prism through which light will be scattered on three polysilikon panel, which is a component of red, green, and blue on the video signal.
17. Modem

 

 The modem has an extension Modulator Demodulator. Modem functioning to convert the digital signal into an analog signal. Data from the computer in the form of digital signal converted by the modem into data in the form of analog signals, when the modem receives data from outside in the form of analog signals, the modem will turn it back into digital form so that the data can be processed by computers.
18. NIC / LAN Card

NIC or Network Interface Card is a card that serves to connect a computer to the Internet network. There are currently two types of NIC are known, among which are physical NIC (example: NIC Ethernet, Token Ring, etc.) and logical NIC (example: Loopback Adapter and Dial-up Adapter).
19. Speaker

Speaker is a device made of metal, membranes, coils and magnets. Speaker has an important role in releasing the results of the processing in the form of sound. Speaker function properly if it is supported by a device called a sound card.
20. Webcam

Webcam is a digital camera connected to a computer. Most webcam is currently integrated with laptop screen. Webcams are also commonly used to take pictures and video through the Internet.

Actually there are many kinds of hardware that I have not mentioned above. But Hopefully if there's time, I will update it immediately. Well, I hope today's post helpful, Thanks
