When a computer is first turned on or restarted a special type of absolute loader is executed called a bootstrap loader. A bootstrap loader is a program that resides in the computer's EPROM, ROM, or other non-volatile memory. It is automatically executed by the processor when turning on the computer

The four necessary conditions for a deadlock situation are mutual exclusion, no preemption, hold and wait and circular set. There are four methods of handling deadlocks - deadlock avoidance, deadlock prevention, deadline detection and recovery and deadlock ignorance.

See lessA partitioned data set is most used for
Partitioned data sets are often called libraries. Programs are stored as members of partitioned data sets. Generally, the operating system loads the members of a PDS into storage sequentially, but it can access members directly when selecting a program for execution.

See lessIf you do not know which version of MS-DOS you are working with, which command will you use after having booted your operating system?
In computing, ver (short for version) is a command in various command-line interpreters (shells) such as COMMAND.COM , cmd.exe and 4DOS/4NT. It prints the name and version of the operating system, the command shell, or in some implementations the version of other commands.

See lessWhat is the initial value of the semaphore to allow only one of the many processes to enter their critical section?
So, in order to allow only one process to enter the critical section, binary semaphore is initialized to 1. Because after entering critical section, semaphore values become 0.

See lessRound-robin scheduling
Round-robin scheduling (Figure 7.151) allocates each task an equal share of the CPU time. In its simplest form, tasks are in a circular queue and when a task's allocated CPU time expires, the task is put to the end of the queue and the new task is taken from the front of the queue.
