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?

  Greater the bandwidth, the higher the bit rate

  Directly proportional

  All of the given answers are valid in this case

  A positive correlation

 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. 

  protocol

  baud rate

  bit rate

  latency

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

  baud rate

  bandwidth

  broadband

  bit rate

 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

  broadband

  baseband

  bit rate

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

  protocol

  bit rate

  baud rate

  latency

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

  bandwidth

  baud rate

  broadband

  baseband

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

  latency

  circuit timing

  protocol timing

  baud reduction

 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

  synchronous transmission

  serial tranmission

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

  new

  dew

  bew

  skew

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

  serial tranmission

  parallel transmission

  asyncronous transmission

  synchronous transmission

 11. _____ = baud rate x bits per baud

  serial rate

  bandwidth rate

  bit rate

  baud rate squared

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

  FALSE

  TRUE

 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.

  TRUE

  FALSE

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

  TRUE

  FALSE
