Microphones also can be used with other applications such as a voice dictation program or a voice conference program.

The set of typewriter-like keys that enables you to enter data into a computer. Computer keyboards are similar to electric-typewriter keyboards but contain additional keys. The standard layout of letters, numbers, and punctuation is known as a QWERTY keyboard because the first six keys on the top row of letters spell QWERTY.

Monitors are sometimes called displays or screens. Information on a monitor is displayed in pixels.

Computer Webcam

A video camera that is used to send periodic images or continuous frames to a Web site for display.

Webcam software typically captures the images as JPEG or MPEG files and uploads them to the Web server.

Flash Drive

A flash drive is a small, portable flash memory card that plugs into a computer’s USB port and functions as a portable hard drive.

USB flash drives are touted as being easy-to-use as they are small enough to be carried in a pocket and can plug into any computer with a USB drive.

When a flash drive is plugged into a computer’s USB port it stores information onto its hard drive.
