5. Why is Windows so popular?

A GUI, the Graphic User Interface, makes use of a Wimp environment: Windows, Icons, Menus and Pointer. This type of interface is user-friendly, where system functions are accessed by selecting self-explanatory icons (pictures representing programmes or documents) and items from menus. A drop-down menu, or pull-down menu, is a list of options that appear below a menu bar when you click on an item.

The pointer is the arrow, controlled by the mouse, which lets you choose options from menus.

The background screen that displays icons, representing programmes, files and folders (directories) is called the desktop. Double-clicking a folder icon opens a window which shows the programmes, documents and other folders contained within the folder.

Peripherals

A peripheral is a device connected to a host computer, but not part of it, and is more or less dependent on the host. These are also input/output devices. It expands the host’s capabilities, but does not form part of the core computer architecture.

It is any auxiliary device such as a mouse, keyboard, hard drive, etc. that connects to and works with the computer in some way. Usually, the word peripheral is used to refer to a device external to the computer, like a scanner, but the devices located inside the computer case are also technically peripherals.

Examples: “Many of the external peripherals I own, such as my scanner and printer, connect to the peripheral ports on the back of my computer.”

There are three different types of peripherals: Input, Output, Storage.

An output peripheral is an external device that provides input and output for the computer. For example RAM has a peripheral output. Some peripherals, such as the external hardrive, provide both input and output for the computer. Usually for every external device there are input and output peripherals. An example of only input peripherals, a keyboard and a mouse are input and peripherals. An example of an output peripherals are hard drives disk. The storage peripherals are also considered to be used to store information on the computer for future use.

Examples are Expansion cards, RAM, graphics cards, computer printers, image scanners, tape drives, microphones, loudspeakers, webcams, and digital cameras.
