Computer Proficiency Test UPDATED
Exam Questions and CORRECT Answers
Four Basic Operations of A Computer - Correct Answer- Input, Processing, Output, Storage
Input - Correct Answer- provide data to process. Devices used are keyboard and mouse.
Performs arithmetic or comparison operations on data.
Processing - Correct Answer- processes data at CPU.
Output - Correct Answer- processes data and outputs it as information. Devices used are
monitors, printers, speakers.
Storage - Correct Answer- allows to recall previous data. Common devices is hard drive.
Others are CD, memory flash, etc.
Hardware Components - Correct Answer- Input, Output, Storage, Memory, Central
Processing Unit (CPU)
Input (Hardware component) - Correct Answer- any resource required for the functioning of a
process, in the course of which it will be transformed into one or more outputs. Devices: the
devices that allow data and instructions to enter a computer (keyboard, mouse, scanner..)
Output (Hardware component) - Correct Answer- the product of the transformation of inputs
by a process. Devices: the devices that allow information to be presented (that is, given out)
to the user, such as a display screen or printer.
Storage (Hardware component) - Correct Answer- the place where a computer puts data.
Memory (Hardware component) - Correct Answer- an area within a computer system that
holds data waiting to be processed.
Central Processing Unit, CPU (Hardware component) - Correct Answer- the chip or chips at
the heart of a computer that enable it to process data. Also known as a processor.
, System Software - Correct Answer- refers to the operating system and all utility programs
that manage computer resources at a low level. The most important program that runs on a
computer is the operating system.
System Software Types - Correct Answer- Operating System (OS), Utilities, Assembler,
Debugger, Compilers, File Management Tools
Applications Software - Correct Answer- An Application is a program, or group of programs,
that is designed for the end user.
Applications Software Types - Correct Answer- Games, Spreadsheets, Word processors,
Databases, Graphics, Communications.
Network - Correct Answer- is a group of two or more computer systems linked together.
Network Types - Correct Answer- Local-area networks (LANs), Wide-area networks
(WANs), Campus-area networks (CANs), Metropolitan-area networks (MANs), Home-area
networks (HANs)
LANs - Correct Answer- Local-area network. The computers are geographically close
together (that is, in the same building)
WANs - Correct Answer- Wide-area network. The computers are farther apart and are
connected by telephone lines or radio waves.
CANs - Correct Answer- Campus-area network. The computers are within a limited
geographic area, such as a campus or military base.
MANs - Correct Answer- Metropolitan-area network. A data network designed for a town or
city.
HANs - Correct Answer- Home-area network. A network contained within a user's home that
connects a person's digital devices.
