Q. Explain Frequency-division multiplexing?
Frequency-division multiplexing (FDM) is a technique for data transmission widely used in telephone, radio, and cable TV systems in which the transmission frequency spectrum (i.e., bandwidth) is divided into smaller bands known as subchannels.
Data transmission between two stations can be achieved in either simplex, half-duplex, or full-duplex mode. In a simplexmode,mainly used in radio and TV broadcasts, information travels only in one direction. Thismode is rarely used in data communications. In half-duplexmode, used by radio communications, information may travel in both directions, but only in one direction at a time. The transmitter becomes the receiver and vice versa. In a full-duplex mode, information may travel in both directions simultaneously. This mode, used in telephone systems, adopts two different carrier frequencies.
Q. Explain about Deadlock Avoidance? To prevent deadlocks two kinds of techniques are used: 1) Static prevention: It employs P and V operators in addition to Semaphores to
Is it possible to pass data to and from include programs explicitly? No. If it is needed to pass data to and from modules it is needed to use subroutines or function modules.
If the throughput scales upward as time progresses and the number of Vusers enhance, this showing that the bandwidth is sufficient. If the graph were to remain relatively flat as t

Proof by Contradiction: Now for forward chaining and backward chaining both have drawbacks. But another approach is to think about proving theorems by contradiction. So we can
