Home Networks

A network of multiple computers at home is a home network. There are different types of home networks which are explain below,

1. Ethernet network

In Ethernet is a wiring network which was started in early 80’s with coaxial cable. Now it’s upgraded and successfully works with twisted pair cables and fiber optic cables.

Ethernet twisted pair use RJ- 45 pin connector to either end of the cable and fiber optic use SFP or SC connectors.

It works in either half or full duplex mode.   

Ethernet devices are consisting of computers, printers or any device having internal or external network interface card (NIC).

Switches, Hub or routers are the director of the network which are use to connect multiple computers and devices in the network

Gateway and bridges are used to connect multiple Ethernet networks together.

Gateway connects to different networks together but Bridge connect connects two similar networks.


It follows any topology to connect multiple devices in the network. An example of start topology in Ethernet network,.


  • Easy to install
  • Reasonable cost
  • Wide speed
  • Highly acceptance

2. Home Power Line cable (PLC) Network

It uses the lines that used in electricity. If in any reason, there is no possibility of internet via Ethernet or wifi then we use PLC to connect with internet.

Home Power Line cable (PLC) Network

How to setup PLC

  • Plug the one end of power line adaptor to modem or router and other end with electricity board.
  • Plug the Ethernet cable from modem or router to computer.

For additional devices connectivity just a power line adopter is required to connect via Ethernet cable.

Data transfer speed in earlier standards is 14Mbps but in the latest versions it speed is up to 200 Mbps.

3. Phone line networks

It is inexpensive and easy to install. It uses telephone lines.

Data transfer speed is 10 Mbps.

4. Home RF Network

RF stands for radio frequency. It uses the radio waves to transmit data. It sends signals through the air.
