compromising emanations of electrical devices. Basically when electrical devices operate, they generate electromagnetic signals that can be intercepted and used to reconstruct sensitive information. “Listening” for these signals is known as “eavesdropping”. With the right equipment an eavesdropper can be hundreds of feet from the signal. This presents a real problem when a computer is processing classified information. The NSA (National Security Agency) has developed the TEMPEST standard which consists of

drivers two way radio, only able to receive while not transmitting. Full Duplex .A full duplex circuit is divided equally. A telephone is a full duplex as it can send your voice signal and receive a voice signal at the same time. 3) Describe how FDM is different from TDM .FDM divides the circuit in a way that the signals can be sent at the same time, each on its own frequency so they do not interfere with one another. TDM makes the connected computers take turns in order to transmit data which wastes
