  Computer Network Types A computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. A computer network can be categorized by their size. A computer network is mainly of four types: LAN(Local Area Network) PAN(Personal Area Network) MAN(Metropolitan Area Network) WAN(Wide Area Network)      

A network switch (also called switching hub, bridging hub, and by the IEEE MAC bridge) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer

An optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: to perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network. to coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units). The diagram below depicts an OLT within a fiber-optic network.

A passive optical network (PON) is a fiber-optic telecommunications technology for delivering broadband network access to end-customers. Its architecture implements a point-to-multipoint topology, in which a single optical fiber serves multiple endpoints by using unpowered (passive) fiber optic splitters to divide the fiber bandwidth among multiple access points. Passive optical networks are often referred to as the "last mile" between an Internet service provider (ISP) and its customers. Components and characteristics A passive optical network consists of an optical line terminal (OLT) at the service provider's central

Network topology is the layout, pattern, or organizational hierarchy of the interconnection of network hosts, in contrast to their physical or geographic location. Typically, most diagrams describing networks are arranged by their topology. The network topology can affect throughput, but reliability is often more critical. With many technologies, such as bus 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 layouts are: Bus network: all nodes are connected to a common medium along this medium. This was the layout used in

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node. Operation When multiple routers are used in interconnected networks, the routers can exchange information about destination addresses using a routing protocol. Each router builds

Flooding is used in computer networks routing algorithm in which every incoming packet is sent through every outgoing link except the one it arrived on.[1] Flooding is used in bridging and in systems such as Usenet and peer-to-peer file sharing and as part of some routing protocols, including OSPF, DVMRP, and those used in ad-hoc wireless networks (WANETs) Types Uncontrolled Flooding: In uncontrolled flooding each node unconditionally distributes packets to each of its neighbors. Without conditional logic to prevent indefinite recirculation of the same packet, broadcast storms are a hazard. Controlled flooding: Controlled flooding has its own two

A mesh network (or simply meshnet) is a local network topology in which the infrastructure nodes that is bridges, switches, and other infrastructure devices connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from/to clients. Basic principles Mesh networks can relay messages using either a flooding technique or a routing technique. With routing, the message is propagated along a path by hopping from node to node until it reaches its destination. To ensure that all its paths are available, the network must allow for continuous

An IP Address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing. Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number. However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, was standardized in 1998. IPv6 deployment has been ongoing since the mid-2000s. IP addresses are written and displayed in human-readable notations, such as 172.16.254.1 in

Computer networking is a group of computer which shair set of common communication protocols over a digital interconneciton for sharing information from a provider or network node.The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies,based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.The node of computer can be a personal computer, server, networking hardware or general purpose node. A node is identified by hostname and network address. Hostname serves as a easy to remember label of node and network address locates and identify the node by
