5.What is Networking?
networking is a group of computers that are interconnected by electronic circuits or wireless transmissions of various designs and technologies for the purpose of exchanging data or communicating information between them or their users. Networks may be classified according to a wide variety of characteristics. This article provides a general overview of types and categories and also presents the basic components of a network.

6.Example of Networking, Post at least 5 examples with picture.

1. A Local Area Network (LAN) is a computer network covering a small physical area,
like a home, office, or small group of buildings, such as a school, or an airport.
The defining characteristics of LANs, in contrast to wide-area networks (WANs), include
their usually higher data-transfer rates, smaller geographic area, and lack of a need for
leased telecommunication lines.

2. A Metropolitan Area Network (MAN) is a large computer network that usually spans a city
or a large campus. A MAN usually interconnects a number of local area networks (LANs) using
a high-capacity backbone technology, such as fiber-optical links, and provides up-link
services to wide area networks and the Internet.

3.Wireless Network refers to any type of computer network that is wireless, and is commonly
associated with a telecommunications network whose interconnections between nodes is
implemented without the use of wires.[1] Wireless telecommunications networks are generally
implemented with some type of remote information transmission system that uses
electromagnetic waves, such as radio waves, for the carrier and this implementation
usually takes place at the physical level or "layer" of the network.

4. A Wide Area Network (WAN) is a computer network that covers a broad area
(i.e., any network whose communications links cross metropolitan, regional,
or national boundaries [1]). This is in contrast with personal area networks
(PANs), local area networks (LANs), campus area networks (CANs), or metropolitan
area networks (MANs) which are usually limited to a room, building, campus or specific
metropolitan area (e.g., a city) respectively.


5. Personal Area Network
A personal area network (PAN) is a computer network used for communication among computer devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and even video game consoles. Such a PAN may include wired and wireless connections between devices. The reach of a PAN is typically at least about 20-30 feet (approximately 6-9 meters), but this is expected to increase with technology improvements
