16
Q

bit

A

“binary digit” and represents the smallest piece of data. Each bit can only have one of two possible values, 0 or 1.

17
Q

Electrical signals

A

Transmission is achieved by representing data as electrical pulses on copper wire.

18
Q

Optical signals

A

Transmission is achieved by converting the electrical signals into light pulses.

19
Q

Wireless signals

A

Transmission is achieved by using infrared, microwave, or radio waves through the air.

20
Q

Throughput does not usually match the specified bandwidth

A
  • The amount of data being sent and received over the connection
    • The latency created by the number of network devices encountered between source and destination
