difference between wireless and wired communication and define semiconductors

Question

Accepted Answer

Wireless communication uses radio waves to transmit data while wired communication uses physical cables. Semiconductors are materials with electrical conductivity between conductors and insulators.

Wireless communication is convenient but can be affected by interference and distance limitations.
Wired communication is more reliable and secure but can be less flexible.
Semiconductors are used in electronic devices such as transistors, diodes, and integrated circuits.
Semiconductors have properties that can be controlled to create electronic components that can amplify, switch, or store electrical signals.
Examples of semiconductors include silicon, germanium, and gallium arsenide.
