Communications and Networks EOU Test

What is a symbol in communication?

• A range of frequencies
• A type of device
• A set of rules
• A type of signal

What is Baud rate?

• The difference in time between an action being initiated and its effect being noticed
• The number of bits transmitted per second
• The range of frequencies a medium can transmit
• The number of signal changes in the medium per second

What is the relationship between bit rate and bandwidth?

• Bandwidth and bit rate are inversely related
• Bandwidth and bit rate are not related
• Higher bit rate results in a higher bandwidth
• Higher bandwidth results in a higher bit rate

What is latency?

• The range of frequencies a medium can transmit
• The difference in time between an action being initiated and its effect being noticed
• The number of bits transmitted over the medium per second
• The number of signal changes in the medium per second

What is a protocol?

• A type of signal
• A range of frequencies
• A type of device
• A set of rules relating to communication between devices

What is serial data transmission?

• Data is sent one bit at a time over multiple communication lines
• Data is sent multiple bits at a time over one communication line
• Data is sent one bit at a time over one communication line
• Data is sent multiple bits at a time over multiple communication lines

What is parallel data transmission?

• Sends data one bit at a time over one communication line
• Sends data one bit at a time over multiple communication lines
• Uses numerous parallel communication lines to send multiple bits between components in a computer simultaneously
• Sends data multiple bits at a time over one communication line

What is skew?

• The leaking of signals from one communication line to another
• The use of multiple communication lines
• The overlapping of bits from different pulses
• The time difference between one bit being transferred and another

What is crosstalk?

• The time difference between one bit being transferred and another
• The use of multiple communication lines
• Signals from one communication line can 'leak' into another
• The overlapping of bits from different pulses

What is bit rate?

• The range of frequencies a medium can transmit
• The number of signal changes in the medium per second
• The number of bits transmitted over the medium per second
• The difference in time between an action being initiated and its effect being noticed
