BASICS
Operating System Functionalities
Security:
The operating system uses password protection and other appropriate safeguards to secure user data. Additionally, it shields user data and programmes from unauthorised users.
Control over System Performance:
In order to maximise performance, the operating system keeps an eye on the system's general health. Keep track of the intervals between system responses and service requests to acquire a complete view of the system's health. This can improve performance by giving important information for resolving problems.
Job Accounting:
The operating system keeps track of how much time and resources are spent by various tasks and users, and this information can be used to calculate how well a user or group of users is using their resources.
Error Detecting Aids:
The OS continuously inspects the hardware to look for issues and keep a computer system from breaking down.
Coordination between Users and Other Software:
Additionally, operating systems organise and distribute other software to computer users, such as compilers, assemblers, and interpreters.
Memory Management:
The primary memory, also referred to as the main memory, is managed by the operating system. The main memory is made up of a huge number of words or bytes, each of which has a unique address. The CPU can access main memory, which is quick storage, directly. Before a programme can be executed, it must first be loaded into main memory.
Process Management:
In a multiprogramming environment, the operating system controls which programmes have access to the processor and how much processing time each process receives. This operating system function is known as process scheduling.
Device Management:
Directories are used to organise files in a file system to improve usage and navigation. These directories may include additional files and directories. An operating system manages files by, among other things, keeping track of the locations where data is stored, user access preferences, and the state of each file. All of these capabilities are collectively referred to as the file system.
