Physical Network Setup

1.  Two or more than two systems with Ethernet Controller (LAN card) and its proper driver must be installed.2.  If you have to establish the network in only 2 systems then have a crossover cabling and if you have to establish the network in more than 2 systems with the help of central connectivity device (Switch / Hub) then have parallel cabling for it.3.  Connect the one end of cable to the switch/hub and another end of cable to the system NIC.4.  Now start the system and assign the computer name, workgroup, IP address, and...

Cabling

Cabling is a process of connecting the cables with its connectors. There are different kinds of cabling:1.  Parallel cabling: - Parallel cabling is done for the different devices. When we have to establish the connection via the different connectivity devices then we make this type of cabling. The different kinds of devices can be From Switch to computer or From Hub to computer.2.  Crossover Cabling: - The crossover cabling is done if we...

Cable

Cable is a bunch of wire which is used to transmit data or information within the network from one host to another host or from one network to another network. There are different kinds of cable but more importantly we use twisted pair cable.1.  Coaxial Cable: - The coaxial cable is outdated now. This cable was used in prior with the BUS topology or Ring topology to establish the network. In this cable there lie two wires. One is the Copper...

IP address can be assigned in 2 ways

1.  Dynamic IP: - Dynamic IP is the changeable IP address which is automatically accepted by the hosts in two cases:     a.  In case of configuring the DHCP server when we use the client server network.     b.  In case of if we do not define the manual IP. If the NIC and its driver are installed and proper configuration is done then in the properties of TCP / IP, the radio button “Obtain an IP address automatically” is selected.2.  Static IP: - This is the constant IP address. This IP...
