It is the transmission of data from one place to another.

• True
• False
• None
• Both

Data transfer interface could be...

• Parallel and perpendicular
  
• Parallel and serial
• Serial and Continuos

• Serial parallel and continuous

Parallel transmission is used

• for long distance communication
• for convert the parallel data into serial data
• for short distance communication
• None

All the bits of data are transmitted simultaneously on separate communication lines

• In serial transmission
• In communication transmission
• In parallel transmission
• In transfer transmission

 In serial transmission, the various bits of data are transmitted serially one after the other.

• True
• False

How many bus lines are used in serial transmission?

• 1

• 2

• 3

• 4

Why is parallel data transmission generally only used over short distances?

• It is too expensive over longer distance

• It is too complicated over longer distance

• There is a higher chance of error over longer distance

• There is a lower chance of delivery over longer distance

A 2 way police radio would be an example of what?

• Simplex Data Transmission

• Half Duplex Data Transmission

• Duplex Data Transmission

Which error checking method involves counting the number of 1s to find whether it is even or odd?

• Check digit
