Q.Differentiate between wired and wireless communication media, giving two examples of each.

The core difference is whether the signal travels through a physical cable or through the open air.

Businesses use wired media for fixed, high-speed links and wireless media where mobility or hard-to-cable areas make cabling impractical.

As Section e explains, communication media are the paths along which data signals travel, and they fall into two groups.

Wired (guided) media send the signal through a physical cable. They are generally faster, more secure, and more reliable, but they are fixed in place and need cabling. Examples: twisted-pair cable, coaxial cable, and optical-fibre cable (any two).

Wireless (unguided) media send the signal through the air as waves, with no cable. They allow mobility and suit places where cabling is difficult, but they are more open to interference and eavesdropping. Examples: radio waves, microwaves, infrared, and satellite communication (any two).

Do not give a device (like a router) as an example of a medium — a medium is the path the signal travels on (a cable or a type of wave). Also keep wired examples (cables) separate from wireless examples (waves).
