Operating systems are software that manages hardware resources and provides common services for software applications. They are found on personal computers, servers, game consoles, smartphones, and other devices. Operating systems perform important functions such as managing the processor and memory, controlling storage devices, providing a user interface, and managing files. They allocate time and memory to processes and enable processes to communicate and share system resources while protecting each process's memory space. Device drivers allow the operating system to communicate with hardware and virtual memory uses the hard drive to supplement physical RAM, allowing for more efficient memory management and multitasking.

1. Operating Systems!By Dhiren Mardania.

2. Definition of operating system?OS(operating System) is the most important program that runs on any type of system.

3. Where will you find OS?Personal computers.SAT NAV.Network server.Games Consoles.Cars.

4. Functions of an OS?Processor Management.

5. Memory Management.

6. Device Management.

7. Storage Management.

8. User Interface.What role does the os play in the managing processor?The OS controls the system for and example if you put in a input such a click on the mouse the OS will process that and give you an output.

9. What is Virtual Memory?Virtual memory uses hardriveas a part of the system memory.virtual memory is a memory management technique made for multitasking. This technique makes a computer architecture's some forms of computer data storage such as RAM (random access memory)

10. What is a file allocation table?A table that operating system uses the locate files on a disk. Due to fragmentation, a file may be dived into many sections that are scattered around the disk.

11. How does Buffer work?Buffer lets information/data to come through. The OS will instruct on buffer to continue taking input from the devices stop sending data to CPU.

12. What is a device driver?Drivers are translation programs which count the messages from OS into messages that the hardware device can understand.

13. File Management.A file manager or file browser is a computer program that makes a user interface to work with file system. The most known operations performed on files or groups of files are create, open, edit, view, print, play, rename, move, copy, delete, search/find , properties and file permissions. Some file managers contain features created by web browsers, including forward and back navigational buttons.Some file managers provide network connectivity.

14. Processor Management.Process management is an important part of any operating system (OS). The OS must allocate resources to processes, enable processes. Also to share and exchange information, protect the resources of each process from other processes and enable. To meet these requirements, the OS must maintain a data structure for each process.
