Define Multiprogramming.
Multiprogramming: A multiprogramming operating system is system which allows extra than one active user program or part of user program to be stored into main memory simultaneously. These operating systems are fairly sophisticated. Each job which enters the system is kept in the job pool. Its pool contains all processes residing upon mass storage awaiting allocation of main memory. If some jobs are about to be brought in memory, and there is not sufficient room for all of them, so the system should choose between them. A time-sharing system is a type of multi-programming system.
Q. Illustrate about Compact Disk Rewritable? CD-RW optical disk can be repeatedly written and overwritten same as with a magnetic disk. Even though a number of techniques have
A sequential circuit is signified by a time sequence of external inputs, external outputs and internal flip-flop binary states. So firstly a state diagram and state table is used t
Clocked SR flip flop A clock pulse is a sequence of logic 0, logic 1, and logic 0 occuring on the CLK input. Time t n occurs before the clock pulse and time t n+1
1. Solve the following grouping problem using the DCA method. 2. Use the ROC methodfor the previous problem. 3. Use the MIP method for the problem above assuming a tota
solve the primal problem using duality and determine the primal and dual solution P= 300x1 + 300x2 S.T. 2x1 + 3x2 => 13 3x1 = 2x2 => 15 x1,x2 => 0
A circuit can be designed to perform manydifferent functions e.g.a circuit has 3 inputs A, B and C and 3 outputs:Output X is logic level 1 (or 'high') if one or moreinputs are at l
Program 'preemption' is? Ans. Forced de allocation of the CPU from a program that is executing on the CPU is called preemption program.
Define clock rate? The clock rate is given by, R=1/P, where P is the length of single clock cycle.
The main benefits of CD-ROMs are: These are removable disks, thus they are suitable for archival storage mass replication is cheap and fast large storage capacity
