Hardware - (ANSWER)The physical components of a computer system.
Internal Hardware Devices - (ANSWER)Processor (CPU)
Motherboard
Random Access Memory (RAM)
Read Only Memory (ROM)
Video and Sound Card
Internal Hard Disk Drive
Motherboard - (ANSWER)Central component of any computer system through
which every other component communicates. Components are plugged into it
directly or indirectly.
Processor (CPU) - (ANSWER)The brain of the computer. It controls everything
that the computer does and processes the data, moving it in and out of the
memory.
Random Access Memory (RAM) - (ANSWER)It stores the information currently in
use, which is constantly changing.
A fast, volatile memory since when the computer is turned off the data is lost. The
more RAM you have the faster your computer works.
, 2
Read Only Memory (ROM) - (ANSWER)Used to store instructions for the
computer to work. The information cant be changed and when the computer is
turned off, it wont be lost. The data can be accessed very fast.
Video Card - (ANSWER)Allows images to be displayed on the monitor. Along with
its installation, software is installed so it tells the computer how to use it.
Sound Card - (ANSWER)Allows the computer to produce and input sounds to and
from the computer by turning analogue data into digital and vice versa.
Internal Hard Disk Drive - (ANSWER)Stores data that is not instantly needed for
an indefinite time. It also stores programmes and is used commonly to back up
data.
External Hardware - (ANSWER)Inputs
Outputs
Peripherals
Input Devices - (ANSWER)Used to get data into the computer system.
They are manual or automatic.
Output Devices - (ANSWER)Used to transfer data out of the computer system.
They are temporary or permanent.
, 3
Peripheral Devices - (ANSWER)Non-essential hardware that connect to the
computer externally.
Software - (ANSWER)Programmes used for controlling the operation of a
computer or processing of electronic data.
(Applications S. and System S)
Applications Software - (ANSWER)Software used in particular situations, which
can be used either in general purpose or in one particular situation.
i.e. Word processing, spreadsheet, data manipulation...
Systems Software - (ANSWER)Files and programmes that make up a computer.
i.e. Compilers, linkers, device drivers...
Secondary/Backing Storage - (ANSWER)Storage devices and media that are not
constantly accessible by a computer system.
Operating System - (ANSWER)Software program that manages computer
resources. They allow components to communicate with each other and enable
the computer to run software applications.
They are CLI and GUI.
, 4
Command Line Interface (CLI) - (ANSWER)The user types in instructions and
commands.
It is fast but complicated to use.
It uses very little RAM.
Used in batch processing.
Advantages of CLI - (ANSWER)1. User communicates directly with the computer.
2. There's a wide range of commands.
3. Needs very little computer power.
Disadvantages of CLI - (ANSWER)1. User must remember complex commands.
2. Lots of typing involved.
3. High chance of errors.
Graphical User Interface (GUI) - (ANSWER)The user points at and clicks objects on
a screen with a mouse.
It is easy to use but needs a large amount of RAM and disk space.
It uses Windows, Icons, Menus,and Pointers (WIMP)
Advantages of GUI - (ANSWER)1. Quick and easy to enter commands.
2. Less chance of errors.
