MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -A network switch (also called switching hub, bridging hub, and, by the IEEE, MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device.

Detailed explanation-2: -The network hub is also called an active multiport repeater, ethernet, and repeater. The hubs and switches with multiple inputs and output ports that form a network, and all the connected devices act as a single network segment and work efficiently, preventing data loss.

Detailed explanation-3: -Hubs cannot provide routing capabilities or other advanced network services. Because they operate by forwarding packets across all ports indiscriminately, network hubs are sometimes referred to as “dumb switches."

Detailed explanation-4: -Hub is a networking devices which is used to transmit the signal to each port (except one port) to respond from which the signal was received. Hub is operated on Physical layer. In this packet filtering is not available. It is of two types: Active Hub, Passive Hub.

Detailed explanation-5: -Hub and Switch are the network connecting devices, both help to connect various devices. Hub works at the physical layer and transmits the signal to the port. Switch route the information and send it over the network.
