Difficulty: Medium
Correct Answer: 10,000 B frame
Explanation:
Introduction / Context: In token ring networks, a station may transmit only while it holds the token, bounded by a token holding timer. The maximum frame length is limited by link rate and token hold time.
Given Data / Assumptions:
Concept / Approach: Maximum bits sendable = data_rate * time_window. Convert bits to bytes by dividing by 8 to get frame size in bytes.
Step-by-Step Solution: 1) Compute bits in 10 ms: bits = 8 x 10^6 * 0.01 = 80,000 bits.2) Convert to bytes: 80,000 / 8 = 10,000 bytes.3) Therefore, the longest frame size is 10,000 B (ignoring headers).
Verification / Alternative check: Cross-check units: Mbps is bits/s; multiplying by seconds yields bits; dividing by 8 yields bytes. No other constraints given, so 10,000 B stands.
Why Other Options Are Wrong: 8000 B: Corresponds to 64,000 bits, which would require only 8 ms at 8 Mbps; underestimates the maximum.
80,000 B: Equals 640,000 bits, exceeding what can be sent in 10 ms at 8 Mbps. 8 x 10^5 bit frame: 800,000 bits; also too large. 1000 B: Only 8,000 bits; far below the limit.Common Pitfalls: Confusing Mbps (bits) with MBps (bytes) and forgetting to divide by 8; mixing milliseconds and seconds.
Final Answer: 10,000 B frame
