If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?
Think about a difficulty that arises as a consequence of the fact that the operating system of a computer uses several processing threads at the same time.
Discuss a problem that occurs as a result of concurrent processing in an operating system.
A process of allocating memory to a process is defined as follows: Describe in layman's terms how the distinction between logical address and physical address can be distinguished. However, I'm not aware how this is handled, and I'd be interested in learning how it is done and what hardware is used to expedite the process. Could you please elaborate?
Create a state machine diagram of operating system processes according to the following description: In general, processes are created and are then waiting to be scheduled if they are able to run. They might be blocking on some external condition (IO, semaphores, other synchronization,...) and might be therefore not able to run. If they are scheduled they are running. At any point they can become blocked due to some external condition. Processes can also be swapped out to the page file / swapping space, which can happen when they are waiting for some external condition or when they are waiting to be scheduled. We are assuming that processes can be terminated at any time.
Describe one problem that arises as a result of concurrent processing in an operating system.
assuming that there are two processes in secondary memory that are prepared to run. The first process is the most crucial, whilst the second is the least crucial, in terms of the processes. One process can only be active at once in the main memory. Describe how the CPU carries it out. You have the choice to describe the procedure utilizing any part of the CPU.
When it comes to process execution, what is the advantage of first allocating it to the I/O queue and then pushing it to the CPU when it is ready? What, in your opinion, will happen if the I/O is not completed correctly? Is the CPU burst going to be affected? What do you mean?
Talk about how an issue with concurrent processing in an operating system is being handled.
Because a) each address generated by the CPU is compared to the relocation and limit registers; b) they use a protection algorithm; c) they are in distinct memory spaces; and d) they use distinct logical addresses, the operating system and other processes are protected from modification by an already running process. Write a comprehensive study of each of the fourteen key NCS programs.
Within the context of an operating system, a discussion should take place on an issue caused by concurrent processing.
Describe what an operating system uses Process Control Block for and why? Explain 4 reasons why a process is created in a computer system Explain 3 reasons why a process may be terminated from a computer system Distinguish between short-term scheduling and long-term scheduling of the processor. Suppose 5 processes A, B, C, D and E arrive at the times indicated, and each of them is executed for the amount of time specified in the table below: Process Arrival Time Service Time (Ts) A 0 4 B 2 3 C 5 6 D 8 4 E…
