- The main components of the Operating System are:
- File Management.
- Process Management.
- I/O Device Management.
- Network Management.
- Main Memory management.
- Secondary-Storage Management.
- Security Management.
File Management
A file is a set of related information which is should define by its creator. It commonly represents programs, both source and object forms, and data. Data files can be numeric, alphabetic, or alphanumeric.
The function of file management in OS:
The operating system has the following important given activities in connections with file management:
- File and directory creation and deletion.
- For manipulating files and directories.
- Mapping files onto secondary storage.
- Backup files on stable storage media.
Process Management
The process management component is a procedure for managing the many processes that are running simultaneously on the operating system. Every software application program has one or more processes associated with them when they are running.
For example, when you use a browser like Google Chrome, there is a process running for that browser program. The OS also has many processes running, which performing various functions.
All these processes should be managed by process management, which keeps processes for running efficiently. It also uses memory allocated to them and shutting them down when needed.
The execution of a process must be sequential so, at least one instruction should be executed on behalf of the process.
Functions of process management in OS:
The following are functions of process management.
- Process creation and deletion.
- Suspension and resumption.
- Synchronization process
- Communication process
I/O Device Management
One of the important use of an operating system that helps you to hide the variations of specific hardware devices from the user.
Functions of I/O management in OS:
- It offers a buffer caching system
- It provides general device driver code
- It provides drivers for particular hardware devices.
- I/O helps you to knows the individualities of a specific device.
Network Management
Network management is the process of administering and managing computer networks. It includes performance management, fault analysis, provisioning of networks, and maintaining the quality of service.
A distributed system is a collection of computers/processors that never share their own memory or a clock. In this type of system, all the processors have their local Memory, and the processors communicate with each other using different communication lines, like fiber optics or telephone lines.
The computers in the network are connected through a communication network, which can be configured in a number of different ways. With the help of network management, the network can be fully or partially connected, which helps users to design routing and connection strategies that overcome connection and security issues.
Functions of Network management:
- Distributed systems help you to various computing resources in size and function. They may involve microprocessors, minicomputers, and many general-purpose computer systems.
- A distributed system also offers the user access to the various resources the network shares.
- It helps to access shared resources that help computation to speed-up or offers data availability and reliability.
