A device is sending out data at the rate of 1000 bps. How long does it take to send
vredina [299]

Answer:

0.01 second ; 0.008 seconds; 800 seconds

Explanation:

Given that:

Sending rate = 1000 bps

Rate of 1000 bps means that data is sent at a rate of 1000 bits per second

Hence, to send out 10 bits

1000 bits = 1 second

10 bits = x

1000x = 10

x = 10 / 1000

x = 0.01 second

2.)

A single character 8 - bits

1000 bits = 1 second

8 bits = (8 / 1000) seconds

= 0.008 seconds

3.)

100,000 characters = (8 * 100,000) = 800,000

1000 bits = 1 second

800,000 bits = (800,000 / 1000)

= 800 seconds
