1 Computer Part 1 25 Question(s) Test ID: Name: Date: 1) Match the term with the definition Output s Storage How to tell it what to do Allows the user to enter information into a system, such as a computer. How it shows you what it is doing Machines or devices capable or representing information from a computer. How it saves data and programs that receive data and retain it for subsequent retrieval. 2) Printer: You can print out information that is in the computer onto paper. By printing you create what is known as a 'hard copy'. There are different kinds of printers which vary in their speed and print quality. 3) Zip Disk/Drive: A Zip disk/drive is a small, portable disk drive used primarily for backing up and archiving personal computer files. Originally it had a capacity of 100 MB, but later versions increased this to first 250 MB and then 750 MB. 4) Keyboard: The Keyboard is the standard data input and operator control device for a computer. It consists of the standard QWERTY layout with a numeric keypad and additional function keys for control purposes 5) Mouse: As it moves across the desk, its movement is shown on the screen by a marker known as a 'cursor'. You will need to click the buttons at the top of the mouse to select an option. 6) Monitor: Visual Display Units (VDU) or monitors are used to visually interface with the computer and are similar in appearance to a television. Visual Display Units display images and text which are made up of small blocks of colored light called pixels. The resolution of the screen improves as the number of pixels is increased. Most monitors have a 4:3 width to height ratio. 7) Compact Disk (CD): A CD is an optical disk impressed with a series of spiral pits in a flat surface which can be read optically by laser. CD-ROM stands for Compact Disk - Read Only Memory. It is now possible to have CD-ROMs where extra tracks of information can be written onto them by the user. These are called read/writable CD-ROMs and these are becoming a popular and cheap method for storage. 8) Speakers: Computer speakers are external speakers. Computer speakers are usually a simplified stereo system without a radio or other media sources built in.
2 9) Joystick: The joystick is a rotary lever. Similar to an aircraft's control stick, it enables you to move within the screen's environment, and is widely used in the computer games industry. 10) Touch Screen: A Touch Sensitive Screen is a pointing device that enables the user to interact with the computer by touching the screen. 11) Projector: An LCD projector is a device for giving presentations generated on a computer. They are the modern equivalent to the slide projector and overhead projector used in the past. Imagery is provided by an attached computer or other video source such as a VCR, DVD, or a cable box. 12) Hard Drive: The hard disk is a direct-access storage medium with a rigid magnetic disk. The data is stored as magnetized spots arranged in concentric circles (tracks) on the disk. Each track is divided into sectors. The number of tracks and sectors on a disk is known as its 'format'. 13) Light Pen: A Light Pen is a pointing device shaped like a pen video display unit.the tip of the light pen contains a light-sensitive element which, when placed against the screen, detects the light from the screen enabling the computer to identify the location of the pen on the screen. Light pens have the advantage of 'drawing' directly onto the screen. 14) Plotter: A peripheral used to draw high-resolution charts, graphs, layouts, an other line-based diagrams. Draws data on paper with a pen held in a mechanical arm. 15) Floppy Disk: A floppy disk is a thin magnetic-coated disk contained in a flexible or semi-rigid protective jacket. Data is stored in tracks and sectors. Once data is stored on a floppy disk it can be 'write protected' by clicking a tab on the disk. This prevents any new data being stored or any old data being erased. 16) Digital Camera: Digital Cameras capture an image which is stored in memory within the camera. When the memory is full it can be erased and further images captured. The digital images can then be downloaded from the camera to a computer where they can be displayed, manipulated or printed. 17) Barcode Scanner: Bar codes are sets of parallel bars of varying thickness and separation that are read optically by transverse scanning. A barcode scanner reads bar codes and converts them into digital character code. 18) Earphones: Earphones (also known as headphones, stereophones, or headsets) receive an electrical signal from a media player or receiver and use speakers placed in close proximity to the ears (hence the name earphone).
3 19) Webcam: A real time camera whose images can be accessed using the Word Wide Web, Instant Messaging, or a PC video calling application. 20) Scanner: Scanners allow information such as a photo or text to be input into a computer. Scanners can be flatbed or hand-held to scan a much smaller area. If text is to be scanned, you would use an Optical Character Recognition (OCR) program to recognize the printed text and then convert it to a digital text file that can be accessed using a computer. 21) Microphone: This system accepts the spoken word as input data or commands. Human speech is very complex, involving emphasis and facial expressions, so complete voice recognition will not be developed for some time. Simple commands from one user can be used to control machines. In this way a paralyzed person can operate a wheelchair or control heating and lighting. 22) SmartBoard: This system accepts the spoken word as input data or commands. Human speech is very complex, involving emphasis and facial expressions, so complete voice recognition will not be developed for some time. Simple commands from one user can be used to control machines. In this way a paralyzed person can operate a wheelchair or control heating and lighting. 23) USB Flash Drive: USB flash drives are compact and easy-to-use flash memory data storage devices that plugs into the USB port. The term "USB flash drive" is a generic term used to describe these products without specifying a particular manufacturer. 24) Robot: Robots are able to perform a variety of tasks as a result of executing instructions contained within a program. Robots in a business sense mean automated machines designed to perform mundane operations which require accuracy, such as assembling cars. 25) SD Card:
