Higher bandwidth
Fibre optic cable an support dramatically higher bandwidths than either twisted pair or coaxial cable currently data rates and bandwidth utilization over fiber optic cable are limited not by the medium but by the signal generation and reception technology available.
Routing Information Protocol (RIP) is a distance vector routing protocol that used hop count as its metric. The maximum hop count is 15, 16 hops are considered unreachable. RIP upd
Consider the following network example. With the indicated link costs along each link in the figure, use Dijkstra's shortest-path algorithm to compute the shortest path from x to a
What is the difference between a hub and a switch? A hub acts as a multiport repeater. Though, as more and more devices connect to it, it would not be able to efficiently manag
Triggers are special user defined actions usually in the form of stored procedures, that are automatically requested by the server based on data related events. It can perform diff
Q. Advantages of Fiber Optics? - Higher bandwidth in comparison to twisted-pair and coaxial cable is not limited by medium but by equipment used to generate and receive signals
Consider a simple wireless data link using channel bandwidth of 40 kHz. The transmit power level is 20 dBm, the link attenuation is 40 dB and the SNRdB at the receiver is 20 dB.
Internet addresses are divided in five distinct types of classes. The classes were designated A by E. class A address space lets a small number of networks although a large number
