Scheduler deals with the problem of deciding which of the process in the ready queue is to be allocated the CPU. Short Term Schedulers, Long Term Schedulers

High-density n-type Complimentary Metal Oxide Silicon field effect transistor.

Main Boot Record is located is sector 0, track 0, head 0, cylinder 0 of the primary active partition.

A blocking assignment is one in which the statements are executed sequentially, i.e., first statement is executed and variable is assigned  a value then second is executed and so on. A non blocking assignment is  one in which statements occurs conturrently, only non blocking assignments should be used in sequential circuit.

e.g.

initial

begin

a=b; //blocking

c<=a; //nonblocking

d=c; // blocking

end

In this example firstly the value of b is assigned to a and this value is assigned to c only after execution of first statement. the second and the third statements are executed simultaneously, i.e. value a ais assigned to c and previous value if c is assigned to d.

Level 1 cache is internal to the chip, Level 2 is external.

Mutual exclusion

Hold and wait

No preemption

Circular wait

The processes that are residing in the main memory and are ready and waiting to execute are kept on a list called the ready queue.

Hard real-time systems required to complete a critical task within a guaranteed amount of time.
Soft real-time computing requires that critical processes receive priority over less fortunate ones.
