A MAN is a means for sharing resources at Telecommunications network high speeds within the network. In a central server environment one host server maintains all active connections and shared information.
A CAN or Campus Area Network is a network that is restricted to a small geographic area such as a building complex or a college campus. Many large Telecommunications network businesses and government agencies use WANs to keep their employees and citizens connected as well as provide a quick and effective way to send and receive information.
These include wide area networks (WAN), local area networks, (LAN), virtual private networks (VPN), client/server networks, network computing, and peer-to-peer networks. Any Telecommunications network network that encompasses a large geographic area is referred to as a WAN or Wide Area Network. It typically incorporates ad hoc connections to other PANs or directly to BlueTooth devices. Virtual Private Networks or VPNs are a type of network that builds on the concept of a WAN however relies Telecommunications network upon the internet and an encrypted connection mechanism to establish a secure environment for internal or external employees or customers.
The CAN incorporates several LANs and usually has connections to a MAN or WAN. Similar in many ways to WANs; Local Area Networks or LANs are responsible for connecting computers in a much smaller limited physical area. In a network computing architecture a computer uses its web browser to connect to another network computer that actually is running the application.
PC) relies on a LAN to connect with a back office network server that is responsible for the connection, retrieval, and storage of data and other critical company or personal information. When information is requested the central server informs the user where they can receive the file and allows the connection directly to the other PC to download.
Examples include IEEE 802.3 (Ethernet), IEEE 802.11 (Wi-Fi) or ITU-T G.hn (using existing home wires, such as power lines, phone lines and coaxial cables). A Personal Area Network (PAN) is a network that is restricted to the area of a person s body. Network computing is a network architecture that has grown with the Internet and resulting connection speeds.
A telecommunications network is a network of telecommunications links and nodes arranged so that messages may be passed from one part of the network to another over multiple links and through various nodes. Telecommunications network links (including their endpoints or nodes ) may in turn be built out of hierarchical transmission systems. Examples of telecommunications networks are: All telecommunication networks are made up of five basic components that are present in each network environment regardless of type or use. A good example of a LAN would be a hotel s wireless Internet offering which is self-contained within their own facility.
A good example of this type would be BitTorrent software which allows small parts of information to be pulled from many sources which once completed compiles into the one file that is being downloaded. In general, every telecommunications network conceptually consists of three parts, or planes (so called because they can be thought of as being, and often are, separate overlay networks): . It is much smaller than Local Area Network.
The MAN will have a physical area between 5 and 50 km in diameter. 2. A MAN or Metropolitan Area Network is a network that covers a region, often a metropolitan area that is bigger than a Local Area Network and smaller than a Wide Area Network and consists of several interconnected LANs.
Peer-to-peer networks can be separated into two major types: Central Server and Pure. A good example of this architecture in use is Google Docs, or Microsoft Office online.
Both services allow users the ability to login to Google or Microsoft servers respectively and work similarly to how it would be performed on their own computing environment. It often provides connections to WAN networks for access to resources outside the scope of the MAN.
The Client-Server network architecture continues to be the main architectural choice for most enterprise network computing. The area of the network size is between LANs and WANs.
With this configuration, a MAN often is then connected to larger WAN networks. There are three features that differentiate MANs from LANs or WANs: 1. The best example of this type was the original Napster file sharing service. A pure peer-to-peer network type has no central server to maintain active users relies instead on the individual computers to seek out all other computers offering the same information being requested.
MANs do not generally belong to a single organization. The equipment that interconnects the network, the links, and the MAN itself are often owned by an association or a network provider that provides or leases the service to others. 3.
In a client/server environment the client (i.e. It is smaller than a Metropolitan Area Network but larger than a Local Area Network.
There are multiple standards for Local Area Networks. This network often serves regional businesses that have several locations throughout the region or entire cities.
