slots into the motherboard and is where all of the information being used by the processor is stored.so that the processor can access all the information related to it quicker than a Hard Drive. When the computer is switched off, the information stored in memory is lost.
any device that can easily be carried and are battery powered with base computing resources in the form of a processor, memory, storage and network access.
a powerful and usually large program that controls and manages the hardware and other software on the computer.
Single-user, multi-tasking (sumt) operating system
used on desktop and laptop computers. (Microsoft Windows and Apple's Mac OS)
Multi-user, Multitask (mumt) Operating system
allows many different users to take advantage of computer's resources simultaneously. Examples are: Unix, VMS and mainframes such as MVS.
Single-user, single task (sust)
Only one user can effectively do one thing at a time. The Palm OS for Palm handheld computers is a good example of a modern single-user, single-task operating system.
CPU (Central Processing Unit) the brain of your computer and is arguably (maybe) the most critical component, as a slow processor will always result in a slow computer.
There are 2 manufacturers of mainstream processors, _____ and AMD. _____ dominates both the mid and high end of the market with its 'core2'processor, while AMD's offerings currently only compete in the lower end of the market.
It provides the 'hub' of your computer that everything else plugs into. It also provides the first level of management, so when the computer is switched on, the motherboard figures out what components are where and how to get them all up and running.
Graphic Card Unit
takes information from the processor and calculates how to display it on the screen. Each card has its own processor and its own memory referred to as Video RAM (VRAM). It processes the information and then passes the result to the VRAM where it is stored ready to send to the monitor.
Hard Disk Drive
is where all the data in a computer is stored when not in use by the processor. Unlike memory, data stored on a HDD remains intact when the computer is turned off. It is an Internal device used for storage of data by the user & also data that is used by the computer's operating system.
computer cooling system
It keeps the components inside your PC cool. Heat is the number one killer of components and even if it doesn't kill them immediately, too much heat will shorten their life as well as making the whole PC unstable.
It is your window to the computer, so it makes sense to choose a good one both in terms of function and quality. It usually have higher resolutions giving you more room to work and a larger area to immerse yourself
Flash drive (usb drive)
is lightweight and can be carried in your pocket. It has large storage capacity than many other removable memory devices and can hold most types of media, which can be edited, rewritten, and deleted multiple times
external hard drive
has a large storage capacity ideal for backing up the computer's hard drive
connects your computer to a network.
allows you to easily connect a keyboard, mouse, scanner, flash drive and any other USB device to your computer
enables your computer to transfer data at high speeds from recording devices such as camcorders and digital cameras
connects your computer to the printer.
one billion cycles in one second
one million cycles in one second
used to connect a computer to the Internet
USB (universal serial bus)
allows you to quickly and easily connect devices to a computer
