- 17Half-duplexData travels in both directions, but not simultaneously
- 18Full-duplexData travels in both directions simultaneously
- 19Bandwidthis the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth data bandwidth,or digital bandwidth.
- 20Bit rateIn telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time.
