Front

What unit is used to measure network speed?

Back

Bits per second

Front

Which of the following is the fastest data transmission rate? 100 Kbps, 1 Mbps, 1 Gbps, 100 Mbps

Back

1 Gbps

Front

How many bits are in a kilobit (Kb)?

Back

1000

Front

Which of these best describes bandwidth?

• The speed at which packets are received
• The maximum rate of data transfer in a network
• The time delay in data transmission
• The total size of a file being transmitted

Back

The maximum rate of data transfer in a network

Front

What is the relationship between transmission rate and file size when calculating download time?

Back

Larger file size increases download time

Front

What is the correct way to convert a file size from bytes to bits?

Back

Multiply by 8

Front

What affects the actual network speed a user experiences?

Back

All of the above (Signal interference, Number of users on the network, Network congestion)

Front

Back

50,000,000 bits per second

Front

What happens when network bandwidth is exceeded?

Back

Network congestion occurs

Front
