What is the content PCB in operating system?
A Process Control Block (PCB, also called Task Controlling Block or Task Struct) is a data structure in the operating system kernel containing the information needed to manage a particular process. The PCB is "the manifestation of a process in an operating system".[1]Included informationImplementations differ, but in general a PCB will include, directly or indirectly:The identifier of the process (a process identifier, or PID)Register values for the process including, notably, the program counter and stack pointer values for the process.The address space for the processPriority (in which higher priority process gets first preference. eg., nice value on Unix operating systems)Process accounting information, such as when the process was last run, how much CPU time it has accumulated, etc.Pointer to the next PCB i.e. pointer to the PCB of the next process to runI/O Information (i.e. I/O devices allocated to this process, list of opened files, etc)During context switch, the running process is stopped and another process is given a chance to run. The kernel must stop the execution of the running process, copy out the values in hardware registers to its PCB, and update the hardware registers with the values from the PCB of the new process.
What are the 5 major activities of an operating system with respect to process management and briefly describe why each is required?
1. process creation: to create a process. 2. process termination: to terminate the process. 3. process abort: in case of abnormal execution of process,it is used to abort the process. 4. process load: to load the process in memory. 5. process execute: to execute the process.
What is an example of process?
A running instance of Notepad is a process.
What is difference between foreground process and background process?
Foreground process has access to the terminal standard i/osBackground process typically run with little or no user interaction at all, they interact with the system.
What is the difference between process switch and mode switch?
Process switch is switch the process state between the status like read, blocked ,suspend. Mode switch is the switch the process privilege between the mode like use mode, kernel mode. Generally a mode switch is considered less expensive compared to a process switch.
What are the steps involved in a switch installation process?
The steps involved in a switch installation process include planning the placement of the switch, preparing the installation area, mounting the switch, connecting the necessary cables, configuring the switch settings, and testing the switch to ensure proper functionality.

In computing what is the purpose of a context switch?
Context switching allows for a computer to multitask. It can suspend one process in order to switch over and run another process. The first process can be brought back up by suspending the second one.

Why context switch must be atomic?
Context switch must be atomic to ensure that the state of the system remains consistent during the switch. This is important because a context switch involves saving the state of the current process and loading the state of the next process. If the switch is not atomic, it could lead to data corruption or inconsistencies in the system, resulting in unpredictable behavior.
