Random Access Memory is also known as the computer’s system memory. It needs power to be read; hence, when a computer turns off, the memory is lost.
Hard disk drive is the main storage device of a computer. It uses uses disks that are made of aluminum or glass to store information. Hard drives are measured in gigabytes. Sometimes a special cache is used for quick retrieval of often-used information (such as web pages).
Microprocessor functions as the central processing unit of the computer which provides computation control. Its speed is measured in megahertz. It holds info about the operating system of the computer. The microprocessor is one type of ultra-large-scale integrated circuit that consists of extremely tiny components formed on a single, thin, flat piece of material known as a semiconductor.
Compact Disk Read-Only Memory is collectively known as CD ROM. With the help of laser optics technology, CD ROM reads information from a CD. However, it is not capable of writing informatioin on the CD.
Floppy disk drive helps store and read data on a removable floppy disk.
Video Card is an expansion card that is connected to the motherboard. It serves as the visual link between the user and its computer, allowing the user to view and manage the computer’s software data.
A LAN Card or Network Interface Card is also an expansion card. Also known as the modem, it helps the computer to connect to another computer on a Network.
The Motherboard is the computer’s circuit board where all the ‘inside parts’ are connected. It contains the microprocessor; important computing components; different types of memory chips; mouse, keyboard, and monitor control circuitry; and logic chips that control various parts of the computer’s function. Having as many of the key components of the computer as possible on the motherboard improves the speed and operation of the computer.
