What role does a hub play in a network?

• A. It increases the overall speed of the network
• B. It connects PCs together to share equal transfer speeds
• C. It serves as a firewall for network security
• D. It acts as a wireless connection point

Answer: (B)

A hub is a fundamental device in a network that facilitates communication among multiple computers or network devices by connecting them together. When connected to a hub, each device is part of a shared communication medium, allowing them to send and receive data with each other. This means that the devices can share equal transfer speeds because the hub broadcasts incoming data packets to all connected devices, ensuring that each device has access to the same information simultaneously. While a hub does connect devices in the network, it's important to understand that it does not increase the overall speed of the network. The speed is inherently limited by the capabilities of the hub and the devices connected to it. Additionally, a hub does not perform the functions of a firewall or serve as a wireless access point. Firewalls are dedicated devices or software designed to protect networks from unauthorized access, while wireless access points facilitate wireless connections to the network rather than simply connecting devices through wired connections.
