Kernel follows Round Robin scheme choosing a swap device among the multiple swap devices in Unix System V.

The time complexity of sequential search is O(n)

It returns -1

Long term scheduler determines which programs are admitted to the system for processing. It controls the degree of multiprogramming. Once admitted, a job becomes a process.

Medium term scheduling is part of the swapping function. This relates to processes that are in a blocked or suspended state. They are swapped out of real-memory until they are ready to execute. The swapping-in decision is based on memory-management criteria.

Short term scheduler, also know as a dispatcher executes most frequently, and makes the finest-grained decision of which process should execute next. This scheduler is invoked whenever an event occurs. It may lead to interruption of one process by preemption.

The description of a data base is called the database schema , which is specified during database design and is not expected to change frequently . A displayed schema is called schema diagram .We call each object in the schema as schema construct.

Yes... so if 8529 gives interrupt then it will be serviced immediately but since INTA pin is left hanging the INSR bit will never be set.. and so whenever my interrupt occurs depending upon priority it will be serviced.. also the ISR address for all interrupts will be same ie 0024H..

Interrupt via trap is nonmaskable, so it will be serviced immediately.

Every line has an upper limit and a lower limit on the frequency of signals it can carry. This limited range is called the bandwidth

Hubs regenerate electrical signals, which are specified at the Physical layer.
