Question

If a file consisting of 50,000 characters takes 40 seconds to send, then the data rate is ______
1. 1 kbps
2. 1.25 kbps
3. 2 kbps
4. 10 kbps

Answer 1

Correct Answer - Option 4 : 10 kbps

CONCEPT:

The data rate is the number of bits per second transferred.

DATA:

File size =  50,000 characters

1 character = 8 bits

1 kb = 1000 b

CALCULATION:

40 seconds = 50,000 characters

40 seconds = 50,000 ×  8 bits

÷ by 40 on both sides

1 second =  10,000 bits

1 second =  10 kb

Therefore the date rate is 10 kbps
