............................................... data transmission is where multiple bits of data are sent at the same time along different
channels in the same cabling.

............................................... data transmission is where multiple bits of data are sent at the same time along different
channels in the same cabling.
serial
parallel
half-duplex
full-duplex
simplex
This type of data transmission occurs when a computer or device is connected to another computer
or device using a single data channel. Data is transmitted one bit at a time, sequentially, down
the channel.

............................................... transmission is a one-directional (or unidirectional) mode of data transmission. The data will
only go one way, and the receiver of the data does not send any data back to the sender.

In .......................................... transmission, two-way communication is possible because both devices can send and
receive data packets. With half-duplex transmission, although the direction of the data flow can be
reversed, transmission cannot be sent in both directions simultaneously.

full-duplex
simplex
This method of data transmission is bi-directional, and data can flow simultaneously to and from
sender to receiver simultaneously. This transmission is made up of two simplex channels,
one flowing in one direction, and the other flowing in the opposite direction. It is the fastest
method of transmitting data.

This type of error checking first requires a protocol to be agreed upon between the sender device
and receiver device. A protocol is a set of rules that both devices will follow. When .............................. is
used as the method of error detection, the protocol can either be even or odd parity.
Whichever type of protocol is used, a ..................................... involves adding an additional binary bit (a 1 or a 0)
to the end of a 7-bit byte to ensure that the number of 1 bits is either even or odd.

The ................. check also recognises that timeouts may occur, in that no acknowledgement is received at
all. In this case, after a set period of time waiting, the data will be sent again, and this will continue
until an acknowledgement comes back to the sender.
