Data Transmisson

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

• True

• False

• None

• Both

Parallel transmission is used

• for long distance communication

• for convert the parallel data into serial data

• for short distance communication

• None

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

• Parallel

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

• Check Digit

• Checksum

• Echo check

• Parity check

Which is a disadvantage of parity checking?

• We cannot locate where the error is

• It takes a long time to calculate

• It can only be done once

  
  

• It is expensive to design

USB stands for:

• Universal Serial Bus

• Unified Serial Bus

• Unique Serial Bus

• Unqualified Students Busk

Full Duplex transmission is where:

• Data can only be transmitted in one direction

• Data can be transmitted in one direction at a time

• Data can be sent both ways at the same time

• A made up term to confuse us

Connecting a phone to a computer would use a serial or parallel connection?

• Serial

• Parallel
