04 - Definitions (baud rate, bit rate, bandwidth e

 1. A long-distance data transmission system transmits data signals as electrical voltages using copper wire. What is the relationship between the bandwidth of the copper wire and the bit rate at which the data can be transmitted?

  All of the given answers are valid in this case

  A positive correlation

  Directly proportional

  Greater the bandwidth, the higher the bit rate

 2. This is the time required for one bit to be transferred from one end to another. It is also called the 'delay' between the sender and the recipient. Measured in milliseconds.
Note: ______ is usually related to the length of the connection and the speed of any packet routing/forwarding that is taking place. 

  latency

  baud rate

  bit rate

  protocol

 3. This is the rate at which the signal changes (per second) in the communication medium. 2 kBd means 2000 signal changes per second.

  bandwidth

  bit rate

  baud rate

  broadband

 4. This is the number of bits that can be transmitted per second. 9,600 bps means that 9,600 bits of data can be transferred per second.

  baud rate

  bit rate

  broadband

  baseband

 5. This refers to the set of rules that need to be established before transmission can take place.

  latency

  bit rate

  baud rate

  protocol

 6. A ______ of 2 Mbps indicates that there is 2 megabits of information lying in the communication medium.

  bandwidth

  baseband

  broadband

  baud rate

 7. a time delay between the moment something is initiated and the moment its effect begins is called ____________

  protocol timing

  baud reduction

  circuit timing

  latency

 8. In this transmission, more than one series of data bits can be transmitted at the same time by using several cables in place of a single cable.

  parallel transmission

  asyncronous transmission

  serial tranmission

  synchronous transmission

 9. As wires or cables get longer, parallel transmission can suffer from this effect:

  bew

  skew

  dew

  new

 10. _______ can operate either in synchronous mode (with a mutual clock) or asynchronous mode (no mutual clock)

  synchronous transmission

  serial tranmission

  asyncronous transmission

  parallel transmission

 11. _____ = baud rate x bits per baud

  bandwidth rate

  bit rate

  serial rate

  baud rate squared

 12. The unit of measurement used for bit rate is vs (volts per second)

  TRUE

  FALSE

 13. Baud rate is essentially the exact same thing as bit rate.

  TRUE

  FALSE

 14. Bandwidth is also known as the 'useful' bit rate, also known as the information rate.

  FALSE

  TRUE

 15. The bit rate and the bandwidth are NOT directly proportional to each other.

  FALSE

  TRUE
