once it is turned on
Baud –
Data transmission speed
Bit rate –
The amount of bits that pass in given amount of time
bit/sec –
bits per second
BOOTP –
Bootstrap Protocol. Allows for computers to be booted up and given an IP address with no user
intervention

A time during processes when something causes the process to slowdown or stop all together
Broadband –
