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

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

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

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.
