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.
Tell me which queue having present queue depth should be greater than zero? Ans) Event queues Open MQ Explorer by selecting Start > Programs > IBM WebSphere MQ > WebSphere
How does the system handle roll areas for external program components? Transactions run in their own roll areas. Reports run in their own roll areas. Dialog modules run
RISC-Means Reduced Instruction Set Computer. A RISC system has decreased number of instructions and more significantly it is load store architecture were pipelining can be executed
Determine the Example of timescale 'timescale 10ns / 1ps Indicates delays are in 10 nanosecond units with 3 decimal points of precision (1 ps is 1/1000ns which is .001 ns).
What is a spanning Tree? A spanning tree is a tree associated with a network. All the nodes of the graph appear on the tree once. A minimum spanning tree is a spanning tree
In the statement Write:/15(10) lfa1-lifnr. The values 15 and 11 can also be defined by variable. No, the value of 11 nad 15 is not described by variable.
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
How many AND gates are required to realize Y = CD+EF+G ? Ans. Y = CD + EF + G for realize this two AND gates are needed (for CD and EF).
State how Shared Memory is used for inter process communication. Define how ptrace is used by debuggers. What are modules? Explain how data mapping takes place among modules
The NAND gate. The NAND gate is equivalent to an AND gate followed by a NOT gate so that the output is 0 when all of the inputs are high, otherwise the output is 1. There may
