Computer hardware (computer hardware) is the physical components that make up an integrated system of Personal Computer (PC).
Typically these devices are assembled and mostly incorporated into a computer case and some others are outside the casing.
The hardware inside the casing generally consists of:
Motherboard (main board)
Motherboard / mainboard is the main component of which is to build a computer. Shaped square board with slots for inserting other components. Its function is to connect all components of the PC. Other computer hardware are all attached directly to the motherboard slot or at least connected using a cable.
Central Processing Unit (CPU)
Also commonly known as "processor" or "brain" of the computer. This is a function of the CPU processing and process all the calculations and commands that make the computer can be operated. Because of the heat it generates, the CPU is always equipped with a fan and heat sink to reduce the temperature. In the latest CPU types, already equipped with Graphic Processing Unit (GPU) that is integrated into the CPU, the graphics data processing.
Random Access Memory (RAM)
RAM serves as a transit point for temporary data operations being executed by the CPU. RAM is volatile, meaning that this device does not store data permanently, only for the required operation alone. The capacity of the RAM on a PC that often we find quite diverse, ranging from 256 MB (megabytes) - 16 GB (GigaBytes)
Video Graphics Array (VGA)
VGA graphics card or the card serves as a link that allows the sending of data between the PC and the graphics display devices such as a monitor or projector. Most computers have a separate VGA card expansion slot mounted on the motherboard. But there is also a computer that has an integrated VGA on the motherboard or the CPU.
Hard Disk Drive (HDD)
Hard-disk serves as the main data storage in a computer system. Operating systems, applications, and documents stored on the hard disk. In the latest PCs, there are also new hardware called Solid State Drives (SSD). Functions the same as the hard-disk, but offers speeds faster data transfer.
Optical Disc Drive
Optical drives are also commonly known as a CD Drive, DVD Drive or ODD. The function of this device is to read and also store data to and from optical disc media such as CD, DVD, or Blu-Ray Disc.
Power Supply Unit (PSU)
Power Supply serves as a converter and distributor of electrical energy from the power outlet (eg, of electricity) to the form of electrical energy that can be used to run the computer components inside the casing. Typically, this PSU is placed at the back of the casing.
Aside from computer hardware contained within the casing, there are also common components that we see outside the casing:
Monitor
Also called a screen or display. The function of the monitor screen is for displaying video and graphics information generated from a computer through a device called a graphics card (VGA Card). This monitor physical form similar to the television, the television is usually only capable of displaying graphical information with higher resolution size.
Keyboard dan Mouse
Keyboard and mouse input serves as a tool to enter text commands, character, or move objects on a graphical interface for processing by a computer. The size and shape of both the tool is quite diverse, but its function is the same.
Beyond the components that we have already mentioned above, there are also computer hardware that not all computers have it:
Uninterruptable Power Supply (UPS)
Often referred to as the battery backup, UPS main function is to store and provide power reserve to be used when the primary power source goes out. In addition as a backup electricity, most UPS also serves as a "stabilizer" that regulates the flow of electricity to match the needs.
Printer dan Scanner
Printer serves as a print output of electronic documents both text and graphics . At home computers typically use paper as the print media . While the scanner function is the opposite of printers that scan the input data from outside the computer into an electronic form that can be processed digitally .speakerThe function of the speaker as the output device is a computer-generated voice . In addition to the speakers , too often we find people who use headphones / headset as the sound output device .Sound Card ( Sound Cards )Function as a liaison between the computer and audio output devices such as speakersmodemThis tool is used to connect computers to the InternetLAN CardFunction as a liaison computer in a network .Thus already explained an overview of computer hardware and diverse functions . For a more in one - by one of the components of this please see the Article Index . May be useful for you all .
