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...
