WHAT IS AN OPERATING SYSTEM:
OPERATING SYSTEM:
Operating system is a collection of set of programs, which manages all the resources of the computer system.It is an intermediate between the user and hardware.An operating system is a set of programs that manages all computer components and operation.A computer can not do anything without operating system operating system must be installed on every computer.Users interact with the computer through operating system most important operating systems Microsoft windows, Linux, Unix.This is system of software that manage computer hardware and software.
TYPE OF OPERATING SYSTEM:
- Batch operating system.
- Distributed operating system.
- Multitasking operating system.
- Network operating system.
- Real operating system.
- Mobile operating system.
BATCH (OS):
Batch operating system process data in the form of batches.The user of a batch operating system never directly interacts with the computer.The batch operating system will work to submit similar kinds of job together in this operating system,user do not intact directly with our computer system.
DISTRIBUTED (OS):
Distributed operating system Failure of one system will not affect the other system because all the computers are independent of each other.the load on the host system is reduced with resource sharing facility,a user at one site may be able to use the resources available at another.
MULTITASKING (OS):
Multitasking operating system Each task gets equal time of execution .The time allotted to execute one task is called a quantum,and as soon as the time to execute one task is complete,the system switches over to another task.
NETWORK (OS):
Network operating system are the system that run on a sever and manage all the networking function.They allow sharing of various files, application, printers, security, and other networking function over a small network of computer like LAN or any other private network.
REAL(OS):
Real operating system in advanced operating system and serve real time system.The response time between input,processing and response is tiny,which is beneficial for processes that are highly sensitive and need high precision.These operating system are useful when may events occur in a short time or within certain deadline,such as real time simulations.
MOBILE (OS):
Mobile operating system is a mobile operating system for smartphone,tablets,and PDA,s.It is a platform on which other applications can run on mobile devices.Example of mobile operating system,Android operating system ,ios operating system, Symbian operating system and windows mobile operating system.
ADVANTAGES OF OPERATING SYSTEM:
Operating system provides a graphical user interface for the users in the form of menu,icons and bottom. Operating system also allow us to sharing the resources with other user it help user to understand the function of a computer it is very easy to use.It can be easily update ensuring correct and efficient use of the computer, hardware providing a platform for software development.
DISADVANTAGES OF OPERATING SYSTEM:
If the operating system is corrupted than it will affect entire system of the computer system will not work.Only some task run at a time they can be complex and difficult to use they can be expensive to purchase and maintain they can be vulnerable to attacks from malicious users.
