MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Routers are intelligent devices, and they store information about the networks they’re connected to.

Detailed explanation-2: -Examples: A network switch works in a similar way to a hub in that it allows network devices to connect to each other. Switches are similar to hubs in that they connect computers/devices to form a LAN. However, switches are ‘intelligent’ devices and transmit data around the network more efficiently.

Detailed explanation-3: -A router can link both LAN as well as WAN. Device Type: The hub is the least intelligent device as it simply passes a received data packet to all the devices connected to it. Both, the switch and router are considered as the intelligent devices as they send the received data packets to appropriate devices.

Detailed explanation-4: -A router is the most intelligent and complex of the three network connection devices listed in this article. Rather than just forwarding data packets to other devices in a single network, routers are designed to forward data packets between two or more networks, as well as direct traffic between them.

Detailed explanation-5: -The primary piece of hardware you need is a modem. The type of Internet access you choose will determine the type of modem you need. Dial-up access uses a telephone modem, DSL service uses a DSL modem, cable access uses a cable modem, and satellite service uses a satellite adapter.
