Used by higher-layer protocols like TCP/IP. The data unit is divided into equal segments, added together using one's complement, and the complement of the sum is sent as an error-checking value. 7. Finding J.S. Katre Computer Network Resources
Noise is unwanted thermal, induced, or crosstalk energy that blends with the transmitted signal. Examples include: Random motion of electrons in a conductor. Crosstalk: Effect of one wire on another.

Attenuation means a loss of energy. When a signal travels through a medium, it loses some of its energy due to the resistance of the medium. Amplifiers are used to compensate for this loss by boosting the signal. Distortion
