Key Terms 2

Question 1

Binary digits are represented and transmitted as discrete electrical pulses. Signaling allows for higher data transfer rates and high data integrity compared to analog signaling.

Answer 1

Digital signals

Question 2

Continuously varying electromagnetic wave that represents and transmits data. Carrier signals vary by amplification and frequency.

Answer 2

Analog signals

Question 3

Transmission sequencing technology that uses start and stop bits or similar encoding mechanism. Used in environments that transmit a variable amount of data in a periodic fashion.

Answer 3

Asynchronous communication

Question 4

Transmission sequencing technology that uses a clocking pulse or timing scheme for data transfer synchronization.

Answer 4

Synchronous communication

Question 5

Uses the full bandwidth for only one communication channel and has a low data transfer rate compared to broadband.

Answer 5

Baseband transmission

Question 6

Divides the bandwidth of a communication channel into many channels, enabling different types of data to be transmitted at one time.

Answer 6

Broadband transmission
