Explanation:

• Networking is the exchange of information and ideas among people with a common profession or special interest, usually in an informal social setting. Networking often begins with a single point of common ground.
• Wide area network (WAN), a computer communications network that spans cities, countries, and the globe, generally using telephone lines and satellite links.
• There are two main types of twisted pair cables, unshielded twisted pair (UTP), and shielded twisted pair (STP), which contains each pair of wires within an aluminium foil shield for further isolation.Ethernet is the traditional technology for connecting devices in a wired local area network (LAN) or wide area network (WAN). It enables devices to communicate with each other via a protocol, which is a set of rules or common network language.
• Modem (abbreviated from MOdulation/DEModulation) is a translating device that can convert signals from digital to analog and back. A modem is a device that translates digital signals from a computer into analog form so that they can be transmitted over analog telephone lines.
