Wired Network

As we know "wired" is the term refers to any physical medium consisting of cables. 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. Mostly in wired network one internet connection is being taken using T1 line, cable modem or using any other means. This connection is shared among multiple devices using wired network concept.

EXAMPLE 1: LAN (Local Area Network): This network consists of ethernet cards housed in PCs or laptops. These cards are connected using ethernet cables. The data flows between these cards. For small wired network router is used to connect few number of desktop or laptop computers. In order to increase the network coverage for more number of systems multiple switches and routers are used. 

Wireless Network

As we know "Wireless" is the term refers to medium made of electromagnetic waves (i.e. EM Waves) or infrared waves. All the wireless devices will have antenna or sensors. Typical wireless devices include cellular mobile, wireless sensors, TV remote, satellite disc receiver, laptops with WLAN card etc. Wireless network does not use wires for data or voice communication; it uses radio frequency waves as mentioned above. The other examples are fiber optic communication link and broadband ADSL etc.

EXAMPLES: 
1. Outdoor cellular technologies such as GSM, CDMA, WiMAX, LTE, Satellite etc.
2. Indoor wireless technologies such as Wireless LAN(or WiFi), Bluetooth, IrDA, Zigbee, Zwave etc.
