When people think about computers, they imagine the computer machine with monitor screen, keyboard, printer and “the box” which contains the electronic parts and circuits (or CPU). It is more difficult to realize, however, that the computer hardware can hardly be useful without the program or system that tells what the computer machine should do. This is also called the software.
Software
-is a program that a computer
uses to perform tasks.
-is any set of instructions
that directs a computer to perform
specific operations.
Note: Computer hardware and
software require each other and neither can be realistically used without the
other.
Two types of software:
1. Systems software- this is the
operating system that is found or bundled inside all computer machines.
Example:
Operating System – is a set of
programs containing instructions that work together to coordinate all the
activities among computer hardware recourses.
Utility Program - System
software that performs maintenance type tasks.
Device Driver - is a program
that controls a particular type of device that is attached to your
computer. There are device drivers for printers, displays, CD-ROM readers,
diskette drives, and so on. When you buy an operating system, many device
drivers are built into the product.
2. Applications software- this
contains the system that commands the particular task or solves a particular
problem.
Application Software may be:
Custom Software that is made
for specific tasks often by large corporations.
Commercial Software packaged
for personal computers that helps with a variety of tasks such as writing
papers, calculating numbers, drawing graphs, playing games and so much more.
MICROSOFT WINDOWS
Microsoft - computer software
company
Windows - any of several
microcomputer operating systems or environments featuring a graphic user
interface.
Microsoft Windows
This is also referred to as
program. Microsoft Windows or Windows for short is an operating environment
between the user and the computer operating system. Also called a shell, it is
a layer that creates the way the computer should work. Windows uses a colorful
graphics interface (called GUI- “gooee”) that can be seen on the computer
screen or monitor whenever the computer is turned on.
Instructional Software
This can be visited on the
internet or can be bought from software shops or dealers. The teacher through
his school should decide on the best computer-based instructional (CBI)
materials for the school resource collection. But beware since CBIs need much
improvement, while web-based educational resources are either extremely good or
what is complete garbage.
