Calculate the required bit rate of a channel if we need to download a text document at the rate of 100 pages per second. Assume that a page has 24 lines, each line has 80 characters, and one character is represented using 8 bits.
- A.
1.53 Kbps
- B.
240 Kbps
- C.
2.1 Mbps
- D.
1.536 Mbps
Attempted by 267 students.
Show answer & explanation
Correct answer: D
Data per page = 24 lines × 80 characters per line × 8 bits per character = 15,360 bits.
Download rate = 100 pages per second.
Required bit rate = 15,360 × 100 = 1,536,000 bps.
Since 1 Mbps = 10⁶ bps, 1,536,000 bps = 1.536 Mbps.
Hence, Option D is correct.
