What is the gap between two processes when the CPU executes a process and then switches into another?
CPU switching from process to another
What is process switching?
Process switching is an operation that provides full route evaluation and per-packet load balancing across parallel WAN links. Process switching involves the transmission of entire frames to the router CPU, where they are repackaged for delivery to or from a WAN interface, with the router making a route selection for each packet. Process switching is the most resource-intensive switching operation that the CPU can perform.
Explain the steps taken by the CPU when switching from process to process?
starts off with the information heading from the HDD/SDD to the RAM then to the cache through the CPU and onto the RAM
What is a Process switch?
In process switching the CPU is required to be personally involve with every forwarding decision. Process switching is similar to doing long math versus doing it the quick way.
What is context schedulling?
Context switching is the process of saving the state of a process or thread, and then restoring the state of another process or thread for execution. Context switching enables multitasking by allowing multiple processes or threads to share a single CPU. It involves saving and restoring CPU registers, program counter, and stack pointers.
What is Non-preemptive algorithms?
Under non-preemtive scheduling ,once the CPU has been allocated to process ,the process keeps CUP until it release CPU either terminating or switching to the waiting state . Bharat Rawal

What is the use of time-sharing in unix?
Time-sharing is designed so that rapid switching between tasks allows the users to believe they have sole use of a scarce resource (CPU). If there is only 1 CPU present then only 1 task can run at a time. With rapid switching it occurs so quickly that it appears as though multiple jobs (tasks) are being serviced.
Describe the action taken by a kernel to context switch between kernel level threads?
Context switching between kernel threads typically requires saving the value of the CPU registers from the thread being switched out and restoring the CPU registers of the new thread being scheduled.
What is a context switching?
Context switching is how the computer's operating system multitasks different processes. It lets one process run for a while and then saves a copy of the process' run state (such as register values) off to the side, restores the run state of the next process back into the processor, and runs it for a while. Context switching is this process of swapping one program out of the CPU and replacing it with another process.
WHAT IS EACH INPUT AND OUTPUT PRT CONNECTED TO THE CPU THROUGH AN OPTOISOLATOR CHIP SUCH AS THE 4N32?
In a system using an optoisolator chip like the 4N32, each input typically connects to the LED side of the optoisolator, allowing the input signal to control the LED, which is isolated from the CPU. The output side, which consists of a phototransistor, interfaces with the CPU by switching based on the input signal's LED activation. This configuration provides electrical isolation between the CPU and the input signals, protecting the CPU from voltage spikes or noise. Overall, the input signal triggers the optoisolator, and the output signal relays this information to the CPU.
What should be the effect of size of the time quantum in round robin CPU scheduling?
The size of the time quantum in round robin CPU scheduling significantly affects system performance. A smaller time quantum can lead to improved responsiveness for interactive tasks but may increase context switching overhead, reducing overall CPU efficiency. Conversely, a larger time quantum can decrease context switching and improve throughput, but may lead to longer wait times for shorter tasks, negatively impacting responsiveness. Therefore, choosing an optimal time quantum is crucial for balancing responsiveness and system efficiency.
