operating system
Today we are learning What is the operating system in this post today? And what are its features? To read, let's start:
The operating system can be easily understood on the basis of the following points: -
1: - The operating system (OS) is a software that functions like a computer and user interface between the user. This is called system software.
2: - The operating system is a set of instructions that store the storage device. And it's a group of programs that manage the resources and operations of computers.
3: - This is the first program to load into the OS computer. It is also called program of programs.
4: - OS manages all the operations of the computer.
5: - There are two types of operating system: -
- character user interface (CUI)
- Graphical user interface (GUI)
character user interface (CUI)
CUI is not user-friendly and & nbsp; always need to type the command to run this OS.
Such as: - DOS is a CUI operating system.
Graphical user interface (GUI)
The GUI operating system is user-friendly and commands are not required to run this operating system, but the program to open it has to be clicked with the mouse.
Like: - Windows is a GUI operating system.
6: - OS work is to run other programs and applications and it functions like a bridge between computer hardware and software.
7: - Without a computer OS is useless (useless).
8: - Multitask operating system runs very short programs at the same time. And the operating system determines which program will run when and how long it will run.
Characteristics of Operating System
1. Memory management: ManageOS memory, it keeps complete information of primary memory and sees which part of the memory is used by which program. Whenever a program requests, it allocates memory.
processor management: This program allocates the processor (CPU) and when a program needs cpu to finish it also deallocate it.
2. Device management: - OS keeps track of all devices, it is also called I / O controller. And the OS also decides which device to be given which device to be given, when and how long it will be given.
3. File Management: - It allocates and deallocate resources and decides which programs to be given the resources, that is to be allocated.
Security (security): -This protects any program or data from unauthorized access. In this, password and other techniques are used.
4. reliability (reliable): -It is very reliable because it can detect any virus and harmful codes.
5.cost: - The operating cost of the operating system is determined based on its features such as: - The cost of windows is around 100 $, while DOS and UNIX operating systems are free.
6.Ease of use: - It can be easily used because it also has a GUI interface.
advantage of operating system (operating system benefits)
The benefits are as follows: -
- It can be easily used because it has a graphical user interface. & Nbsp; And new users can run computers easily by this.
- Through this, we can share one data with a lot of users.
- Through this, we can share resources like: - Printer.
- They can be easily updated.
- It is safe such as: - windows have windows defender which detects any type of harmful files and removes them.
- Through this, we can install any game or software and run them.
- Some operating systems (like: - LINUX) are open source, we can run them on free on my computer.
disadvantage of operating system
- Some operating systems are free but some are expensive such as: - windows costs around 5000 ₹ to 10000 की.
- Running linux is a bit harder to compare than Windows.
- Sometimes it does not support any hardware,
- The risk of viruses in mac OS is high.
