Other Components
UPS (Uninterruptible Power Supply):
It stands for Uninterruptible Power Supply. It is a small battery which is used to giving a power supply. When electricity is absence. This battery or PC and data and properly shutting down the computer.
Motherboard
A motherboard is the main circuit board inside a computer
that connects the different parts of a computer together. It has sockets for
the CPU, RAM and expansion cards (Example- discrete graphics cards, sound cards, network cards, storage cards etc) and
it also hooks up to hard drives, disc drives and front panel ports with cables
and wires.
Card, Port, Slot:
Cards are the printed circuit board which are use to hold the chips. There
are many type used in a PC like memory cards, graphics cards, sound cards, network cards, storage cards.
Many type of Port is serial port, parallel port.
SMPS (Switch Mode Power
Supply)
It stands for switch mode power supply use
to like a transformer of computer to give the power supply for all
compensates.
SMPS
converts the input AC voltage to the DC voltages needed by the personal
computer. In older computers, AT SMPS were used. Currently ATX 12V SMPS are
dominant.
Peripheral Devises:- Input and output devises combined called peripheral
devises.
Computer Software
The branch of computer
science in which we study about the use of computer and, developing the program
to perform desired task/job is called computer software.
Software is the set of
programmer which is flows in sight the wire just like a current.

Software
Type of Software: Computer software is memory classified into to
broad categories:
1. System Software
2. Application Software
System
Software: System software also known
as system package control and operate computer system. This software is
directly works for computer hardware components.
System Software can be further classified into
three parts.
(i) Language Translator
(ii)Operating system
(iii) Utility Software
(I) Language
Translator: This type of
programmer which are used to convert high level language to low level language
and low level language to high level language.
Assembler: - this programe is convert assembly language (Gnomic Code and Address
code language) to machine language and machine language to assembly language.
Compiler: - it is also a compiler compile the whole programe and shows the total
errors at the last. It checks the programe at the time and takes very less time
to excide any programe.
Interpreter: This Translator converts the programe line by line and checks errors
line by line. So it takes very long time to execute any programe.
(II) Operating
System:
v
An operating
system is an integrated set of program that controls the resources (CPU,
Memory, Input/Output devices etc.) of a Computer system and provides its users
with an interface.
v
The OS is the
computers master control program. The OS provides us with a command that
enables us to interact with the PC. When we issue a command, the OS translate
it into code that the machine can use.
Some
popular operating system are- Unix, Ms –Dos, Microsoft Windows, Microsoft
Windows NT, Linux.
Function
of the Operating System:
- It displays the on screen
elements which we interact.
- It loads programs into the
computers memory so that we can use them.
- It coordinates how programs
work with the computers hardware and other software.
- OS manage the way how
information is stored on and retrieved from disk.
Types of Operating system
1.
Real time operating system
2.
Single user /single tasking OS
3.
Single user /Multitasking OS
4.
Multi user / Multitasking OS.
1. Real time operating system:
A real
time operating system is a very fast, relatively small OS.
It is
needed to run real – time applications.
It may
support multiple simultaneous tasks or it may support only single tasking.
Real time
applications are needed to run medical diagnostics equipment, life – support
system, scientific, instruments & industrial system.
2. Single user /single tasking OS
An
operating system that allows a single user to perform just one task at a time
is a single user single tasking operating system.
To a user
a task is a function such as printing a document, writing a file to disk,
editing a file or downloading a file from a network server.
Ms-Dos is
an example of a single OS.
3. Single user /Multitasking OS
A single
user – multitasking operating system is one that allows a single user to
perform two or more functions at once.
The most
commonly used personal computer usually run such Oss
4. Multi user / Multitasking OS.
A multi
user – multi tasking operating system is an operating system that allows
multiple users to use programs that are simultaneously running on a single
network server called terminal server.
In a
multi user – multi tasking operating system environment all or most of the
computing occurs at the server.
Examples
of Multi user – Multi tasking Oss
User Interface
When we
work on a computer we see and use a set of items on the screen Taken together,
theses items are called the user interface.
The User interface provided by the OS can be character based
or graphical.
The two
most common types of user interface are:
CUI - Character user
Interface/Command Line User Interfaces
GUI - Graphical user
Interface.
(III) Utility Software
Utility software is the software
that helps to manage and tune the computer hardware, operation systems, and
application software by running small tasks. Examples of utility software is an
Anti-virus, disk cleaner, registry cleaner and data compression to name a few.
(2) Application Software
This
type of software which is develops according to the requirement of user and
full fill the needs of user.
