Networking 2 - Essay Example A deeper comparison is as shown in the table below. The radio infrastructure will require 4 satellites which will be established at four points whereby one will be in the line of sight of the next satellite.This infrastructure will use Hertzian Insurgency frequency since the normal FM frequency is not applicable over satellites. The orbits for the satellites should be contradictory to that of the moon so as to defy the interference that the moon causes to them as a result of the lunar gravitational pull. A signal in a connection is like water in a river only that the destination of the signal is defined. In addition to the message carried by the signal, there isalso the destination address and the origin address. The signal is broken down into smaller segments called data packets and these packets are allocated numbers according to the segment of the signal in which they belong. For example the first segment will be allocated the first number and the last segment will be allocated the last number. These packets use different pathways in the network specifically the shortest route to the destination and when they all get to the destination they are assembled according to the segment number hence making the original signal. The network selected employsthe use of twisted pair cables. This network’s structure has an additional device that is the hub. The network uses a topology called the star topology whereby all the components are connected to the hub. This includes the gateway which refers to the computer connected to the internet which provides connection to all the other computers. The hub acts as the central switching device that controls how the messages and signals are relayed within the network. It is also the location whereby signals are kept whenever a transmission medium (cable) is in use since two signals cannot be transmitted over the same cable. Another alternative device that can be used in place of the hub is the switch (also
