Question

Explain all the functions of operating system

Answer 1

Answer:

Hey guys here is your answer

There are Many Functions those are Performed by the Operating System But the Main Goal of Operating System is to Provide the Interface between the user and the hardware Means Provides the Interface for Working on the System by the user. The various Functions those are Performed by the Operating System are as Explained below:-

Operating System as a Resource Manager

Operating System Also Known as the Resource Manager Means Operating System will Manages all the Resources those are Attached to the System means all the Resource like Memory and Processor and all the Input output Devices those are Attached to the System are Known as the Resources of the Computer System and the Operating system will Manage all the Resources of the System. The Operating System will identify at which Time the CPU will perform which Operation and in which Time the Memory is used by which Programs. And which Input Device will respond to which Request of the user means When the Input and Output Devices are used by the which Programs. So this will manage all the Resources those are attached to the Computer System.

Storage Management

Operating System also Controls the all the Storage Operations means how the data or files will be Stored into the computers and how the Files will be Accessed by the users etc. All the Operations those are Responsible for Storing and Accessing the Files is determined by the Operating System Operating System also Allows us Creation of Files, Creation of Directories and Reading and Writing the data of Files and Directories and also Copy the contents of the Files and the Directories from One Place to Another Place.

1) Process Management : The Operating System also Treats the Process Management means all the Processes those are given by the user or the Process those are System ‘s own Process are Handled by the Operating System . The Operating System will Create the Priorities foe the user and also Start or Stops the Execution of the Process and Also Makes the Child Process after dividing the Large Processes into the Small Processes.

2) Memory Management: Operating System also Manages the Memory of the Computer System means Provide the Memory to the Process and Also Deallocate the Memory from the Process. And also defines that if a Process gets completed then this will deallocate the Memory from the Processes.

3) Extended Machine: Operating System also behaves like an Extended Machine means Operating system also Provides us Sharing of Files between Multiple Users, also Provides Some Graphical Environments and also Provides Various Languages for Communications and also Provides Many Complex Operations like using Many Hardware’s and Software’s.

4) Mastermind: Operating System also performs Many Functions and for those Reasons we can say that Operating System is a Mastermind. It provides Booting without an Operating System and Provides Facility to increase the Logical Memory of the Computer System by using the Physical Memory of the Computer System and also provides various Types of Formats Like NTFS and FAT File Systems.

Operating System also controls the Errors those have been Occurred into the Program and Also Provides Recovery of the System when the System gets Damaged Means When due to Some Hardware Failure , if System Doesn’t Works properly then this Recover the System and also Correct the System and also Provides us the Backup Facility. And Operating System also breaks the large program into the Smaller Programs those are also called as the threads. And execute those threads one by one

hope it help you ☺️

Functions of Operating system:

• Memory Management - Manages memory of computer system and try to keep the memory clear and clean always. Cache is also removed automatically by OS.

• File Management - OS Manages the different files and documents in computer system.

• Device Management - OS brings complete, proper control and co-ordination in different tasks of system. In short, it manages device.

• I/O management - Operating system helps user to input the data. The output formed inside the CPU is given to user with the help of Operating system only.

• Networking -  Operating system manages the internet and network connection inside the computer system. Operating system creates interface between our computer and to network to which are connected.

• Security - Operating system plays very important role in security of computer system. As it has it's inbuilt security function, This function helps us to browser more secure.

• Processor Management - Operating system also manages the processor. It sends the input given by user, send it to user in the form of output; Also, Manages the different operations according to their intensity.

Operating system is a system software that manages the software resources, Hardware devices and provides the common application services for computer system. Operating system installs the connection between Humans and Computers. Because of operating system only, we can perform work and give instructions to the computer.

In short, Operating system is a system software that creates the interface between computer and user. Operating system helps us to communicate with computers without knowing their language. It is not easy to use a computer system, mobile, TV any digital device without having operating system in it.

Operating system provides common services to computer system like File search, Calculator, Various in built apps, Word, PowerPoint and excel etc. Due to which, it becomes easy to use a computer system. If we use a computer system without OS, then we will just seeing Binary codes on our screen. Which aren't easy to get understood.

Features of Operating system:

1. Resource the allocation of memory
2. Protects the information and data inside the computer system
3. Manages the memory
4. Virtual multitasking
5. Program execution
6. Allows computer system with network
7. Installs the connection between User and Computer.

Types of Operating system:

• Multiprocessing OS

• Multitasking OS

• Batch OS

• Mobile OS

• Network OS

• Distributed OS

• Real Time OS

What is 32 Bit and 64 Bit ?

32 Bits system can handle ram only 3.2 GB of ram. 32 Bits system processes the data simultaneously and output in given in seconds. This systems required 32 bit CPU and OS.

64 Bits systems can handle ram up to 17 Billion GB. This systems processes the data in the bit of second. This are very simultaneous systems. This systems 64 bit CPU and OS.

Popular Operating systems for computer system:

• Windows - Versions: Windows 10, 8, 7, XP, 98...

• Apple OS - Versions: Mojave, Catalina, Mac OS X

• Linux - Versions - Red Hat, KDE....

• Ubuntu

• Chrome OS

• Fedora
