Modulation is the process of varying a carrier signal's properties to transmit information.

• Modulation involves changing one or more properties of a high-frequency carrier signal in accordance with the information being transmitted.

• Common modulation techniques include Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM).

• Modulation allows multiple signals to share the same transmission medium without interfering with each other.

• It is essential in tele...read more

Wavelength is the distance between two consecutive peaks or troughs of a wave.

• Wavelength is commonly used to describe electromagnetic waves such as light and radio waves.

• It is measured in units such as meters, nanometers, or angstroms.

• Shorter wavelengths correspond to higher frequencies and higher energy, while longer wavelengths correspond to lower frequencies and lower energy.

There are two main versions of IP addresses: IPv4 and IPv6.

• IPv4 addresses are 32-bit numerical addresses, expressed in four octets separated by periods (e.g. 192.168.1.1).

• IPv6 addresses are 128-bit hexadecimal addresses, expressed in eight groups of four hexadecimal digits separated by colons (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
