Memory management technique in which system stores and retrieves data from secondary storage for use in main memory is called: RAID Questions and Answers 1.
The systems which allows only one process execution at a time, are called: Processes Questions and Answers 2.
In operating system, each process has its own: Processes Questions and Answers 3. One is that it is designed to make sure a computer system performs well by managing its computational activities.
Another is that it provides an environment for the development and execution of programs. With an increased number of processors, there is a considerable increase in throughput. It can also save more money because they can share resources. Finally, overall reliability is increased as well. A kernel is the core of every operating system.
It connects applications to the actual processing of data. It also manages all communications between software and hardware components to ensure usability and reliability. Real-time systems are used when rigid time requirements have been placed on the operation of a processor.
It has well defined and fixed time constraints. Virtual memory is a memory management technique for letting processes execute outside of memory.
This is very useful especially is an executing program cannot fit in the physical memory. The main objective of multiprogramming is to have a process running at all times.
With this design, CPU utilization is said to be maximized. In a Time-sharing system, the CPU executes multiple jobs by switching among them, also known as multitasking. This process happens so fast that users can interact with each program while it is running.
It is the most common type of multiple-processor systems. In this system, each processor runs an identical copy of the operating system, and these copies communicate with one another as needed.
Server systems can be classified as either computer-server systems or file server systems. In the first case, an interface is made available for clients to send requests to perform an action.
In the second case, provisions are available for clients to create, access and update files. In asymmetric clustering, a machine is in a state known as hot standby mode where it does nothing but to monitor the active server.
A thread is a basic unit of CPU utilization. In general, a thread is composed of a thread ID, program counter, register set, and the stack. FCFS stands for First-come, first-served. It is one type of scheduling algorithm.
Implementation is managed by a FIFO queue. RR round-robin scheduling algorithm is primarily aimed for time-sharing systems. A circular queue is a setup in such a way that the CPU scheduler goes around that queue, allocating CPU to each process for a time interval of up to around 10 to milliseconds.
Deadlock situations occur when four conditions occur simultaneously in a system: Mutual exclusion; Hold and Wait; No preemption; and Circular wait.
