Comparison Between Wired Network and Wireless Network

Comparison Between Wired network & Wireless Network

wired Network

In computing terminology, the term "wired" is used to differentiate between wireless connections and those that involve cables. A wired setup uses physical cables to transfer data between different devices and computer systems. The cables can be copper wire, twisted pair or fiber optic. Wired network is used to carry different forms of electrical signals from one end to the other. Most wired networks use Ethernet cables to transfer data between connected PCs. Ethernet works or operates in a narrow range and it is little bit difficult to configure as compared to wireless networking technologies.

Wireless Network

wireless network refers to the use of infrared or radio frequency signals to share information and resources between devices. Wireless technologies are designed to reduce the time and different type of obstacles created by the cables. Wireless network does not use wires for data or voice communication; it uses radio frequency waves as mentioned above. Many types of wireless devices are available today;for example, cellular mobile, handheld PCs, satellite receivers, laptop, PDAs, wireless sensors etc.

          

COMPARISON BETWEEN WIRED NETWORK AND WIRELESS NETWORK

Below table mention comparison between wired network and wireless network:-

Sr. No	Parameters	Wired Network	Wireless Network
1	Installation	Difficult (Because more no’s of compound are used during installation and required no’s of cables for connecting each and every computers)	Easy installation
2	Speed and Bandwidth	High (up to 100mbps)	Low (up to 54mbps)
3	Reliability	High(Due to existence of wired technology and as manufactured cable have higher performance)	Reasonably high( because if the major section like router break down the whole network will be affected)
4	Cables	Ethernet, copper and optical fibers	Works on radio waves and microwaves
5	Mobility	Limited, as it operates in the area covered by connected systems with the wired network	Not limited, as it operates in the entire wireless network coverage
6	Security	Good	Weak
7	Interference	Less (Networks are invisible to other wired networks. The presence of one wired network has no effect on the performance of another wired network)	Higher (the potential for radio interference due to weather, other wireless devices, or obstructions like walls)
8	Quality of Service	Better	Poor
9	Connection setup time	Less	More
10	Devices used	Hubs and Switches	Routers
11	Cost	Less as cables are not expensive	More as wireless subscriber stations, wireless routers, wireless access points and adapters are expensive
12	Applications	LAN (Ethernet), MAN	WLAN, WPAN(Zigbee, bluetooth), Infrared, Cellular(GSM,CDMA, LTE)
13	Standards	IEEE802.3	IEEE802.11a, IEEE 802.11b , IEEE802.11g
