COMPUTER PARTS

Simply put, we can find computer parts of a device that looks, that there is a CPU, monitor, keyboard, mouse, and speakers. However, as a system, the computer has a very complex and complicated enough for those who do not understand it.

If grouped according to function, the computer elements are grouped into five sections, namely the operation of the device, storage devices, input devices, output devices, and enhancement.

1. Device Operation

Operation of the device is in the CPU (Central Processing Unit). This section is a device that serves as the brains of computers, the tasks include systems store, process data and manage computer systems work.

a. Motherboard

 







Motherboard is an important component in the completeness of a computer system. Why? Because the motherboard was all computer components are connected. The motherboard also who controls the performance, relationships, and the communication antarkomponen. Without the motherboard, the computer system will not be able to walk.

The term motherboard actually has another name, that mainboard and system board. In the IT world, the standard term used is the motherboard. In other words, the mainboard is mention of an alternative to the motherboard. Physical form of the motherboard is a printed circuit board is attached by a variety of chips, expansion slots and memory slots, as well as the processor socket. 

b. Processor 

Once the motherboard, the other main components of the computer system is the processor. The processor is the brains of any computer sophistication. Basically, technically, this component is assigned to conduct calculations, logical operations, and decision making based on the flowchart diagram that has been programmed.

In general, this component of the process data, giving instructions to other components connected to the system, and control hardware connected to the motherboard. Based on the activities undertaken, the processor is divided into three parts, namely Arithmatical Logical Unit (ALU), Control Unit (CU), and the registers. 

c. Memory 

You may often hear the term RAM. The term is often associated with memory. Not entirely wrong, and not entirely true anyway, because the two terms (RAM and memory) actually have different meanings.

Memory can be described as a temporary data storage electronic device that will be or has been processed by means of the process and have a high speed data access. As for RAM, a term often used to refer to memory, actually refers to a type of memory based on its ability to read and write again.

Objects in the form of pieces of PCB containing memory chips and are often cited as the RAM is actually referred to as the memory module. Memory functions within the computer system is to store data temporarily. While the data in question is the data to be processed to a processor or just processed from the processor.

Based on its ability to write and read, the memory is divided into two types:  

Read-Only Memory (ROM) is a memory-only memory whose contents can be read. In other words, the data stored in it can only be written once and then the memory contents can only be read without being able to be changed.

Random-Access Memory (RAM). This type of memory used as main memory in a modern computer system. Nature of this memory can be read and rewritten. In other words, data stored in memory can be re-written, readable, and be changed by one method. 
  
d. VGA Card 

  

The graphics card is an expansion card (expansion card) that serves as a data processing device which issued the video and graphics to the screen the viewer like a monitor or projector.

   

e. Sound Card

Sound Card or Sound Card also served as an introduction to the input of the processor. Sound Card delivered it to the speaker. 

2. Data Storage Devices 


By type, data storage media is divided into two parts, namely Magnetic Media (for example, diskette, hard disk, flash) and Optical Media (CD-ROM, CD-R, CDRW, DVD-R, DVD-RW). 

a. Hard Drive

Hard drive is a hardware component that functions as a store of data. The data stored in the hard disk will not be lost even if the computer dies. In a hard disk, there is usually more than one platter or plate to enlarge the capacity of data that can be stored. 

b. Diskette 

Flash diskette with the same function to store the data, the size of the circle of dishes only 3.5 inches, the way the operation is to put it into the device in that a Flopydisk. However, nowadays the use of floppy disks is rarely found, even to say is not there.

But the capacity of floppy disks are very small, even a widely circulated even just have a capacity of 1.4 MB (Megabytes). Currently diskettes are very rarely used anymore in the computer system.

 c. Flashdisk

Flash data storage media is very popular now, in addition to its slim so easy to carry everywhere also design an attractive and diverse. As we have seen, has a capacity of 1.4 MB floppy disks, while the flash has a capacity of 128 MB, 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, and so on. 

d. Disk (CD & DVD) 

  
Compact Disk or more familiarly called the CD and DVD Digital Versatile Disc or equally shaped disc or compact disc. Both media are distinguished from the capacity. CD store with a capacity between 650-700 MB of data while a DVD can store from 2 GB to 17 GB. 

3. Input Devices 

a. Keyboard 
 





The keyboard is a device used to type or to enter (insert) text, giving orders to the computer, as well as to control the operation of the computer. There are different types of layout of the buttons on the keyboard, but the most popular use is the QWERTY layout. 

b. Mouse 

Mouse serves to give commands to the computer. The mouse has two buttons on the left and right, in general the left means the "OK", while the right button is usually a choice or option. There is also a scroll that serves to raise and lower the page / display on the screen.  

c. Scanner 

Scanner is a tool to scan documents, photographs, waves, temperature and others. Scan results will be processed by computer and converted into digital data. We can process the data returned by the application of image processing or text processing application.
                                                     

d. Monitor

We often refer to the monitor or computer display screen. The term is usually depicted on a monitor screen box that can display anything from a computer device. As a monitor output media have significance as other computer devices. All are important units in a computer system where one is not then the system will not work.
Also described as a computer monitor output device that displays characters and / or images, either still or moving, which is processed / ordered from the CPU via the input media.

4. Output Device 

Output equipment can be either hard-copy device, that device used to print text or images on hard media. For example a printer. Output devices can also generate / remove soft copy, and so-called Soft-copy device for displaying text, graphics, and sound in the form of soft media, for example, monitor and speakers.

5. Enhancements
Which includes computer enhancements include:

•     LAN Card for computer networks,

•     Modem to the Internet or fax,

•     TV / FM tuner for the installation of television or radio

•     Pen tablet for drawing,

•     Web Cam for video call activity, and so forth.
