Across
- 1. A bit sent at the end of an asynchronous data transmission to indicate the end of the data. Always different from the start bit
- 4. Type of data transmission where data can be sent both ways along the communications channel but only one way at a time
- 9. Data Transmission where single bits are sent one after another along a single wire.
- 10. Transmission system in which the sender and receiver have separate clocks which are not kept synchronised. Instead, the clocks are synchronised temporarily at the start of a transmission.
- 11. Data Transmission where multiple bits are sent down several wires simultaneously.
- 12. For a transmission medium, the range of signal frequencies it may transmit.
- 13. Type of data transmission where data can be sent both ways along the communications channel at the same time
Down
- 2. The rate at which signals on a wire may change.
- 3. The sending and receiving devices exchange signals to establish that they are each ready to initiate data transfer.
- 5. In an 8 bit byte 7 bits are used to send the data and last - the parity bit - is used to ensure there are either an odd or even number of 1's in the byte.
- 6. Type of data transmission where data can be sent one way along the communications channel only
- 7. The number of bits transmitted per second
- 8. A set of agreed signals, codes and rules to be used for data and information exchange between computers.
- 9. A bit sent at the beginning of an asynchronous data transmission to indicate the start of the data. Always different from the stop bit
