Operating Systems Quiz

The functions of an operating system include managing computer hardware and software resources, providing a user interface, facilitating communication between hardware and software, handling system security, and managing file systems.

Operating system is a software that acts as an intermediary between computer hardware and user applications, and manages computer resources and provides common services for computer programs.

An example of an operating system is Microsoft Windows, macOS, Linux, or Unix.

An operating system manages computer hardware and software resources and provides common services for computer programs.

An operating system is important because it allows users to interact with the computer and coordinates the use of the hardware among the various application programs for various users.

Windows, macOS, and Linux are examples of popular operating systems used on personal computers.

Process synchronization is the coordination of multiple processes to ensure they do not interfere with each other while accessing shared resources, such as memory or files. This is important for maintaining data consistency and avoiding issues like race conditions and deadlocks.

Process synchronization aims to address common problems such as race conditions, where the output of the processes depends on the timing or order of execution, and deadlocks, where processes are unable to proceed because they are waiting for each other to release resources.

Some common techniques for process synchronization in operating systems include the use of semaphores, mutex locks, monitors, and atomic operations like test-and-set or compare-and-swap.
