Application software
A set of computer programs designed to carry out specialized tasks for the user.
For example:
Database programs, electronic mail, word processors, media players, and spreadsheets.

Communication device
A device that assists in data transmission.
For example, microphones, speakers, cameras, mouse, modems, cables, and ports.

Computer
An electronic device which responds to a specific set of instructions in a well-defined manner.
For example:
Laptops, personal digital assistants (PDAs)

Desktop computer
A personal computer (PC) in a form intended for regular use at a single location. The term 'desktop' refers specifically to a horizontally-oriented case, usually intended to have the display screen placed on top to save space on the desk top.Today the phrase usually indicates a particular style of computer case. Desktop computers come in a variety of styles ranging from large vertical tower cases to small form factor models that can be tucked behind an LCD monitor. Most modern desktop computers have separate screens and keyboards.

Embedded computer
A special-purpose computer system designed to perform one or a few dedicated functions, often with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts.The system uses a CPU chip, but that is not a general-purpose workstation, desktop or laptop computer. Such systems generally use microprocessors, or they may use custom-designed chips or both.
For example:
Intelligent controllers for televisions, cameras, cell phones, personal digital assistants (PDAs), traffic light, robot, trains, planes, machine tools, space vehicles, automobile engines, consumer and office appliances, etc.

Graphical user interface
A type of user interface which allows people to interact with electronic devices like computers, hand-held devices (such as MP3 Players, portable media players, gaming devices), household appliances and office equipment. A GUI offers graphical icons, and visual indicators as opposed to text-based interfaces, typed command labels or text navigation to fully represent the information and actions available to a user. The actions are usually performed through direct manipulation of the graphical elements.

Hardware
The physical components of a computer system, in the form of computer hardware. They are touchable.
For example:
Disks, disk drives, display screens, keyboards, printers, boards, soundcard, motherboard, mouse, and chips.

Installing
To connect or set in position and prepare for use. In computer terminology, install refers to putting software on a computer (install the software), or adding hardware components to computer (install the hardware).

Internet
A global network connecting millions of computers that transmit data by packet switching using the standard Internet Protocol (IP). More than 100 countries are linked into exchanges of data, news and opinions and carry various information and services, such as electronic mail, online chat, file transfer.

Network
A collection of computer systems linked together as a transmission and devices media. There are many types of computer networks, including:
· local-area networks (LANs) : The computers are geographically close together (in the same building).
· wide-area networks (WANs) : The computers are farther apart and are connected by telephone lines or radio waves.
· campus-area networks (CANs): The computers are within a limited geographic area, such as a campus or military base.
· metropolitan-area networks MANs): A data network designed for a town or city.
· home-area networks (HANs): A network contained within a user's home that connects a person's digital devices.
