Subject: Computer Networks

Topic: OSI Layer Model

Options:

1. Option A: coaxial cable
2. Option B: twisted pair cable
3. Option C: optical fiber
4. Option D: electrical cable

Correct Answer:

Option C: optical fiber

Explanation:

Fiber optics is considered to have the highest transmission speed among the all mentioned above. The fiber optics transmission runs at 1000Mb/s. It is called as 1000Base-Lx whereas IEEE standard for it is 802.3z. It is popularly used for modern day network connections due to its high transmission rate.
