Two very common types of networks include: Local Area Network (LAN) Wide Area Network (WAN) You may also see references to a Metropolitan Area Networks (MAN), a Wireless LAN (WLAN), or a Wireless WAN (WWAN). In this tutorial we will learn about LAN, MAN and WAN networks along with knowing more about Communication Networks can be of following 5 types. A computer network is a group of two or more computer systems linked together. There are many types of computer networks, including the following.

If this sounds familiar to you, you likely have a PAN in your house without having called it by its name.
Local Area Network A local types of network network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, types of network as data storage and printers. LANs can be built with relatively inexpensive hardware, such as hubs, network adapters and Ethernet cables.
A LAN typically relies mostly on wired connections for increased speed and security, but wireless connections can also be part of a LAN.
High speed and relatively low cost are the defining characteristics of LANs. Local Area Network — This is often used types of network a computer network with a wired connection.
Types of Communication Networks
This is perfect for internet cafes and homes. Wide Area Network — Types of network is the wireless version of a shared network. The internet is a well-known wide area network connection. Also called as Wi-Fi.
Types of Network Protocols Protocols are used as a medium to access the network with the right credentials. Types of network is needed to make the connection possible and is often used as an identifier for the devices that are connected within the network.
You can control these protocols if you wish. Here are the well-known protocols for network connections: The computers are geographically close together that is, in the same building. The computers are types of network apart and are connected by telephone lines or radio waves.
The computers are within a limited geographic area, such as a campus or military base.

Different network topologies can affect throughput, but reliability is often types of network critical. With many technologies, such as types of network networks, a single failure can cause the network to fail entirely. In general the more interconnections there are, the more robust the network is; but the more expensive it is to install.
Common network topologies Common layouts are: This is still a common topology on the data link layeralthough modern physical layer variants use point-to-point links instead.
This is the typical layout types of network in a Wireless LANwhere each wireless client connects to the central Wireless access point.
A fully connected network: Note that the physical layout of the nodes in a network may not necessarily reflect the network topology.
As an example, with FDDIthe network topology is a ring actually types of network counter-rotating ringsbut the physical topology is often a star, because all neighboring connections can be routed via a central physical location. Overlay network[ edit ] A sample overlay network An overlay network is a virtual computer network types of network is built on top of another network.
Nodes in the overlay network are connected by virtual or logical links. Each link corresponds to a path, perhaps through many physical links, in the underlying network. The topology of the overlay network may and often does differ from that types of network the underlying one.
