Batch processing system
In
batch processing system environment, all the programs from various users are
connected and fed into the computer later by the operator one after the other
and are executed in sequence with this arrangement, programmers do not have to
run their own programs themselves. Hence, the user may have to wait for hours
or even days before getting computer respond.

The computer has to run a compete programme without
stopping to that the other programs have to wait for long period before gaining
access to the computer. If there is bug (mistake), in the programme, the job
may be aborted and will have to be resubmitted after correction.

Online Process System
The
term on – line pertains to equipment or devices that are in direct
communication with the CPU. On – line processing system may therefore be
defined as a computer base system capable of processing information through
peripheral devices under the control of the CPU. Also it is a system in which
information reflecting current activity is introduced into the system as soon
as it occur. In essence, it is system that requires immediate processing.

Single User Operating System
This
is the operating system for personal computers. This is an operating system
that allow just one person to work on a computer at a time, it can run just one program at a time. A
specific example of such operating system is MS- DOS. MS-DOS is acronym for
micro- soft Disk operating system, it is an application package it is designed
for single user application and cannot make use of the terminals. It can run
one program at a time.

Multi User Operating System
This
is an operating system that allows more than one user to work on the computer
system through the help of terminal at any particular time. In other word, it
allows a number of users consisting of various people in different department
to process their own particular requirement. Each of the users is connected to
the computer by a terminal which is under the control of the CPU. A specific
example of multi user operating systems is UNIX.

Real Time Operating System
A
real time processing system is an on- line system with quick response
capability such system has the capability of accessing and upholding computers
files using terminals equipment quickly enough to affect decision making. Here
input data are processed as it becomes available, regarding of the order in
which the data arise.

A typical example of real – time system is an
air-line reservation system. This is a real time application where customers
can request air-line information and receive response quickly enough to make
decision concerning the reservation of an air – line seat. The primary
objectives of the system are to provide instant information on demand and to
prevent double, or over booking of seats on Air Craft

Time Sharing Processing System
This
is a situation in which many users has interaction with the computer system.

Job Control Language
The
purpose of the job control language is to control the running of job on a
computer system. And this is as result of several jobs that run concurrently on
a large computer e.g. main frame.

Network Operation System
This
is another operating system that is on network basis, it service many computers
on net activity, two or more computers may be connected by selected cables.

Local Area Network (LAN)
Is
the process whereby two or more computers are connected within a building
office or campus.
the process whereby two or more computers are connected within a building

Wide Area Network (WAN)
This
warrants connection of many computers together but in a wide range i.e. the
distance above 10 mile. This is possible with the use of modern,
Telecommunication, satellite etc. satellite are relay or repeater station
launched into orbit for the purpose of communication.
