Show answer & explanation
Correct answer: D
Answer: 10 kbps
Explanation:
Step 1: Convert characters to bits. Assume 1 character = 1 byte = 8 bits, so 50,000 characters × 8 = 400,000 bits.
Step 2: Compute the data rate by dividing bits by time: 400,000 bits ÷ 40 s = 10,000 bits/s.
Step 3: Convert to kilobits per second: 10,000 bits/s = 10 kbps (using 1 kbps = 1,000 bits/s).
Note: The calculation assumes 1 character = 1 byte (8 bits). If a different character encoding is used, adjust the bits per character accordingly.
Therefore the data rate is 10 kbps.
