Basic Network Types – LAN/WAN
Basic Network Types:
Network types are often defined by function or size. The two most common categories of networks are:
• LANs (Local Area Networks)
• WANs (Wide Area Networks)
A LAN is generally a high-speed network that covers a small geographic area, usually contained within a single building or campus. A LAN is usually under the administrative control of a single organization. Ethernet is the most common LAN technology.
A WAN can be defined one of two ways. The book definition of a WAN is a network that spans large geographical locations, usually to connect multiple LANs. This is a general definition, and not always accurate. A more practical definition of a WAN is a network that traverses a public or commercial carrier, using one of several WAN technologies. A WAN is often under the administrative control of several organizations (or providers), and does not necessarily need to span large geographical distances.
A MAN (Metropolitan Area Network) is another category of network, though the term is not prevalently used. A MAN is defined as a network that connects LAN’s across a city-wide geographic area. An internetwork is a general term describing multiple networks connected together. The Internet is the largest and most well-known internetwork.
A VPN (Virtual Private Network) allows for information to be securely sent across a public or unsecure network, such as the Internet. Common uses of a VPN are to connect branch offices or remote users to a main office.
So it’s a little bit about Basic Network Types, My next blog topic is Network Architectures .

Rather Be disagree, Trust the science. Rather, the question should be cutting stone. Let the intellect sharpened fingernails, tax protest. Whatever I do, at least, do not agree all the words effortlessly. For all those who accept spontaneously, they do nothing, they would clear the way for self.
