Communications

Communications

• Communication is the activity of conveying information.

• Communication requires a sender, a message, and an intended recipient.

• Thus communication can occur across vast distances in time and space.

• Applications– AM and FM radio, television, wireless communications,

satellite communications, deep-space communications, telephony, data storage, Internet, and quite a few others
