Works of Operating systems
The operating system does many works but the first work it did when we On the computer is to load the ram and allocate the user software. Other works are given is below list.
1. Memory Management
3. File Management
4. Processor Management
5. Device Management
7. Software and user interface
8. system performance
Now let’s talk about these all works of Operating system one by one in the detail.
Memory Management – Operating system Manage both the memories that are Primary and Secondary memory. Main memory is the memory that is used by CPU Directly and RAM is handled by the Operating system.
The operating system handles all parts of the main memory that which part is being used and which is not. To run or process any program Operating system gives Memory for it and takes it back when the program is done.
Security – When we start our mobile or computer if you had set a password to unlock it then the operating system first asks for the password.The main work in the security of the operating systems to block unauthenticated access.

File Management – The files are the storage of a lot of directories and with the help of File management, we can find our data easily. File management is managed by the Operating system.
File management does Resource allocation and De-allocate. it manages the resource and also information, locations, and status of all the files stored in your computer or laptop.
Processor Management – When it comes to doing multiprogramming tasks then the Operating system decides which task needs to be done first and how much resource and time it takes. its also called process scheduling in the Operating system.
All the process is allocated by CPU and after the first task done the second task will automatically start. you can check the running tasking in Task manager.
Device Management – Every Computer use drivers like video drivers, Sound driver, Graphics driver, wifi driver, Bluetooth driver and many more. it all comes in device management.
Device Management tracks all the computer drivers’ performance which is also called I/O Controller. Devive Management gives output like Video playing or printing and after the work done it Deallocate the device.
Error – Operating system find errors in Computer or laptop and show then to use by a computer screen. The Operating system also can fix these errors by your command.
These errors can be Shown at any time and in Any program like playing a video or staring a software.
Software and User interface – Compiler, Interpreter and assembler these all assign the tasks. The operating system does communication between user and system.
The operating system creates user-friendly tasks and takes command from the user to give these commands to the software.
System Performance – As the name is describing itself it Checks the system performance and also manages it. System performance gives the timing that how much time one task takes to complete.
These all are the main works of the Operating system and without an operating system, these programs cant be done.
Types of Operating Systems
1. Batch Operating system
2. Multiprogramming Batch Operating system
3. Simple Batch Operating System
4. Network Operating System
5. Multiprocessor Operating system
6. Time-Sharing Operating system
7. Distributed Operating System
8. Real-Time Operating System
What you have learned today?
Today if you have read this full article then you have learned about what is the operating system and for what reason we use it. we also have discussed the names of operating systems and works of Operating systems.
As per new and updated operating systems are coming there are more easy to access, user-friendly and fast in use. for example windows 10 is the latest operating software of windows and it’s much better and faster than the all old windows versions.
Which operating system you guys think is user-friendly and used more than others. Let us know by commenting down below and if you have any queries related to OS then you can ask us.
