Bridge
It is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart.
Wide Area Network (WAN)
Local Area Network (LAN)
Metropolitan Area Network (MAN)
The following are fact about NETWORK except one.
A network consists of two or more computers that are linked in order to share resources (such as printers and CD-ROMs), exchange files, or allow electronic communications.
The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.
There are three basic types of networks.
Network is the arrangement or set-up of the hardware and software that make up a computer system.
It is a contraction of the terms modulator and demodulator. Modems perform a simple function: They translate digital signals from a computer into analog signals that can travel across conventional phone lines. It modulates the signal at the sending end and demodulates at the receiving end. What do you call this networking device?
Router
Switch
Hub
Modem
It is an internetworking system capable of joining together two networks that use different base protocols.
Network Gateway
Network firewall
Bridge
Hub
This refers to a networking device that is small that join multiple networks together.

What is the difference between router and modem?
The modem connects your home to the Internet, while a router creates the network inside your house.
Modem has public IP address while Router assigns IP address.
Modem uses a WAN while Router creates LAN
All of the above
The following are true about network and networking devices except one.
Because both bridges and routers connect networks together, they can be interchangeable to a degree. A router could replace a bridge, connecting two networks. But it does not make sense to replace a router with a bridge because routers can forward non-local traffic and bridges will simply drop traffic for addresses not in their local tables.
A router also connects two LANs and moves traffic via IP addresses.
Hub is a device that gathers the signals from devices that are connected to it, and then regenerates a new copy of each signal
A bridge connects two LANs within a single domain, using Media Access Control addresses to determine destinations.
It is a small, simple, inexpensive device that joins multiple computers together.
