Question

The topology of Ethernet system is

• A. Ring
• B. Star
• C. Mixed
• D. Bus

Hint:

When you see "Ethernet" in a modern context, think "Star topology" with a central switch. The older bus topology is now mostly of historical interest.

Answer 1

The Correct Option is B

Step 1: Understand the evolution of Ethernet. Early Ethernet standards (like 10BASE5 and 10BASE2) used a bus topology, where all devices shared a single coaxial cable.
Step 2: Understand modern Ethernet. Contemporary Ethernet standards (like 10BASE-T, 100BASE-TX, 1000BASE-T) use a star topology. Devices are connected to a central switch or hub using twisted-pair cables. This is the dominant topology in use today.
Step 3: Evaluate the options. While legacy Ethernet used a bus, virtually all modern Ethernet installations use a star topology. In the context of a current exam, "Star" is the expected answer. Bus is historically correct but outdated.
