An interface between computer hardware and computer users is known as Operating System (OS). An Operating system is software that can perform various tasks such as memory management, file management, handling the output and input, controlling the peripheral devices like printers and disk drives, and lastly the process management. An operating system brings several benefits to software development and computer software. Here are some mentioned primary functions by the best and cheap operating system. 

Memory management: This management refers to the management of main memory and primary memory. Main memory is the giant ray of bytes and words where each byte and words has its address. Main memory offers fast storage, which can directly be accessible by CPU. The operating systems do the following activities for memory management. 

1. It keeps tracks of primary memory.
2. In the process of multi-programming, OS decides which method will get the memory how much and when. 
3. It allocates the memory.
4. It de-allocates the memory when the system has been terminated.  

Process management: In the multi-programming environment, an operating system decides which process will get the processor how much and when. This whole process is known as process scheduling. An operating system for process management performs the following activities.

1. It keeps the updated status of every process and also keeps track of processors.
2. It allocates the CPU to a process.
3. It can also de-allocate the processor whenever the process is no longer required.

Device management: The Operating system manages the communication of devices through their respective drivers, following activities performed by the Operating system for device management.

1. The program is responsible for the task call I/O controller, by which it can keep track of every device. 
2. It decides which process will get the device for how much time and when. 
3. An efficient way of allocating the devices
4. It can even de-allocate the devices.

File management: A file system is organized in the directories for easy usage and recognition. These following directories might contain other directories and files. Here are some activities performed by the Operating system for file management.

1. It keeps track of location, status, uses, information, etc. This collective system is known as a file system. 
2. It allocates and de-allocates the resource.
3. It decides who will get the resources. 

Advantages of Operating System

• Computing source

An operating system acts as the interface between computer hardware and the user. Users are allowed to input the data, process through it, and access the output. With the help of the operating system, users can communicate with the computers for performing several take-ups like arithmetic calculations and many more. Search for the best windows operating software that can offer the best service to your system. 

• Resource sharing

An operating system does allow us to share useful files and data with several other users via Modems, Fax machines, printers, and players. Besides all these, a user can share a particular file or data with other users simultaneously via email. Images, media files, and apps also can be transferred from your PC to other devices with the help of a cheap operating system. 

• User friendly 

When windows operating software came into existence, then it introduces GUI or Graphical User Interface. This made usage of computers more natural than others. It made it easier for users to communicate, interact, and understand computer machines. 

• Safeguarding of data

There are many user data stored on your computer, which can only be accessed through the operating system. Above accessing and storing data, the operating system also provides safety and security to the files and data. You will have to search for the best windows operating software that gives you access and storage and manages your data safely and securely.

• Software updates

An OS or operating system is software that needs to be updated regularly for handling great fleeting features, which are increasing continually. Along with other software and apps, the operating system must improve its benchmark to manage various essential works of the computer. An operating system can be updated easily without any complexity. 

• Multitasking

An operating system can perform several tasks at the same point in time. It helps out the users to carry off several functions at the same point in time.

Final words

The operating system is the central part of any computer system, and it manages everything in your order. So it is essential to choose the best and cheap operating system. Operating systems can perform the various tasks at the same point of time which give lots and a lot of benefits to the user. Choose wisely for getting the best service.
