CompTIA A+ Core 1 (220-1101) — Question 45

Which of the following describes the operational difference between hubs and switches when transmitting data to a specific computer inside the network?

Answer options

• A. Switches only send data to the specific computer, while hubs send data to all computers inside the network.
• B. Switches compress data, while hubs send uncompressed data.
• C. Switches receive data and route it to all computers inside the network, while hubs receive data and do not route.
• D. Switches scramble data, while hubs send data in the original form.

Correct answer: A

Explanation

The correct answer is A because switches intelligently direct data specifically to the intended recipient, while hubs indiscriminately broadcast it to all devices in the network. Options B, C, and D contain inaccuracies about the functions of switches and hubs, as hubs do not route data or alter its form, and switches do not compress or scramble data.
