100
Define the term computer
An electronic device that accepts data, processes the data, stores the information and produces an output.
100
Define the term Word processor
A program used to create, edit format word documents
100
Define the terms Input, input device
Input - data that is entered into the computer Input device - device used to enter data into the computer
100
Define the terms output, output device
Output - data generated out of the computer Output device - a device used to generate data out of the computer.
100
Differentiate between Primary and Secondary storage
Primary - temp storage of data Secondary - Permanent storage of data
200
differentiate between data and information
data is raw facts and figures; information is processed data
200
Define the term word processing
the act of using a computer to create, edit, format print word documents
200
List four input devices
joystick mouse trackball touchpad
200
List the two main types of output and differentiate between the two.
hardcopy - permanent output softcopy - temporary output
200
List the two types of Primary Storage; give one difference
RAM - volatile ROM - non volatile
300
Give two advantages and two disadvantages of using a computer.
Advantages: does repetitive task well accuracy disadvantage: Can cause redundancy in the workplace introducing computers can be expensive
300
Give four uses of word processors
edit, create, save, print. format
300
List the two main categories if input device and give two examples of each
pointing - mouse, joystick scanning - barcode reader, scanner
300
List three output devices
speaker printer projector monitor
300
Differentiate between random/direct and serial/ sequential data access
random - goes directly to required file whereas serial starts from the beginning of the file to access required file.
400
List the four types of computers from smallest to largest
micro, mini, mainframe, super
400
Look at the following and list any three formatting features.
bold, underline, italics
400
Expand the following Acronyms: OMR OCR MICR
OMR - optical mark reader OCR - optical character recognition MICR - magnetic ink character recognition
400
Define the terms resolution and pixel
resolution - the sharpness and clarity of an image pixel - tiny dots that make up the image on a screen
400
Compare and contrast the CD and DVD giving similarities and differences.
Both are optical devices; CD more suitable for data and music files DVD more suitable for movies they both use random data access.
500
With the aid of a diagram explain how data flows in a computer.
Input------process---output Storage
500
Look at the following and explain how to move line three and make it line five.
Select cut and paste at line five.
500
Name the input device that can be used to enter large amounts on data into the computer.
What is a scanner
500
List the two main types of printers; differentiate and give one example of each type
Impact - Makes contact with paper while printing e.g dot matrix Non Impact - little or no contact is made during printing e.g laser printer
500
Compare and Contrast the magnetic tape and Hard Disk
they both store large amounts of data; Magnetic uses serial data access whereas hard disk uses random data access.
