Modem provides bi-directional data communication Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet. Modem is a device which convert the digital signal to.

Analog single and Analog signal to digital. The use of.

Modem in networking is to connect your computer to internet.

Using telephone line.

Routers are small physical devices that join multiple networks together. Technically, a router is a Layer 3 gateway device, meaning that it connects two or more networks and that the router operates at the network layer of the OSI model.

Network repeaters regenerate incoming electrical, wireless or optical signals. With physical media like Ethernet or Wi-Fi, data transmissions can only span a limited distance before the quality of the signal degrades. Repeaters attempt to preserve signal integrity and extend the distance over which data can safely travel. A network repeater is a device used to expand the boundaries of a wired or wireless (WiFi) local area network (LAN).

A bridge has a foot in each network and acts on the link layer (level 2). It is able to pass frames from one network to another in an intelligent manner. A bridge, after a period of learning, is able to identify MAC addresses of nodes on each side of the bridge. It prioritizes the frames that actually need to be transferred, so that the traffic on each side is best. A bridge is very effective if the two networks A and B hardly communicate with each other; otherwise, it is best to communicate with an Ethernet cable for example.

Data link layer makes frames and error detection and work with physical layer (wire, wireless) , bridge (use to join two similar networks) operates on this layer so bridge the answer.

You haven't mentioned that whether they are same type of LANs or two dissimilar LANs.

If they are similar then the answer is Bridge
or if they are Dissimilar then answer is Router.

Bridge, router, gateway, everything in network link similar or dissimilar types of network. But the decision of correct device always confused me. I can't differentiate them.

Router is wrong because asking for frames and frames are developed in data link layer, in which bridge or switch works while router is working on network layer(packet).

Bridge is basically used to connect two topological different type of LAN segments. It also works on L2 layer. So Bridge is right answer.

The main work of bridge is to convert the protocol from one LANs to another. Means support the different interface to work.

Bridges operate in datalink layer and are used to connect LANs. More or less they are obsolete now.

Bridge provide LANs. To LANs connectivity. Because they are operate in data link layer.

Bridges working in data link layer and bridges are used to connects the LAN segments.
