What is Operating System? An operating system (OS) is the software that manages the hardware and software resources of a computer. It acts as an intermediary between the computer's hardware and the applications that run on it.  The main functions of an operating system include managing the computer's memory, processing power, and input/output operations (such as reading and writing files, connecting to the internet, and managing peripherals like printers and keyboards). An operating system also provides several important services such as: Memory management: Allocating and de-allocating memory to the running processes Process management: Creating and scheduling the processes. File management: organizing and maintaining files on storage devices. Security: implementing security features such as access control and process isolation Networking: implementing protocols and interfaces for communication over networks. Linux OS architecture: Linux V/s Unix: Unix is a proprietary operatin...

Major Functionalities of Operating System:

  Major Functionalities of Operating System:  Resource Management:  When parallel accessing happens in the OS means when multiple users are accessing the system the OS works as Resource Manager, Its responsibility is to provide hardware to the user. It decreases the load in the system. Process Management:  It includes various tasks like  scheduling and termination  of the process. It is done with the help of  CPU Scheduling  algorithms. Storage Management:  The  file system  mechanism used for the management of the storage.  NIFS ,  CFS ,  CIFS ,  NFS , etc. are some file systems. All the data is stored in various tracks of Hard disks that are all managed by the storage manager. It included  Hard Disk . Memory Management:  Refers to the management of primary memory.

Basic of Operating System

What is Operating System ? Operating system is an interface between user and the computer hardware. The hardware of the computer cannot understand the human readable language as it works on binaries i.e. 0's and 1's. Also it is very tough for humans to understand the binary language, in such case we need an interface which can translate human language to hardware and vice-versa for effective communication. Types of Operating System:  Single User - Single Tasking Operating System  Single User - Multitasking Operating System  Multi User - Multitasking Operating System Single User - Single Tasking Operating System In this type of operating system only one user can log into system and can perform only one task at a time. E.g.: MS-DOS Single User - Multi tasking operating System This type of O/S supports only one user to log into the system but a user can perform multiple tasks at a time, browsing internet while playing songs etc. E.g.: Windows -98,Xp,vista,Seven etc. Multi User ...
