There are several different types of computer networks. Socalled routing protocols are the family of network protocols that enable computer routers to communicate with each other and in turn to intelligently forward traffic between their respective networks. The internet protocols are the worlds most popular opensystem nonproprietary protocol suite because they can be used to communicate across any set of interconnected networks and are equally well suited for lan and wan communications. Frame type this is the format of the packet that is used by the network. Networks using the ip and ipx protocols assign logical addresses which are made up of the mac address and the network address to the devices on the network, this can all become quite complex suffice it to say that the network layer takes care of assigning the correct addresses via ip or ipx and then uses routers to send the data packets. A protocol is a set of rules that governs the communications between computers on a network. Lan, man and wan are the three major types of the network designed to operate over the area they cover.

The protocols used currently were developed many years ago, and are similar in concept to the rules of diplomatic interaction that dictate who speaks first, who bows to whom and so forth. Three typical types of routing protocol are chosen. Network protocols are the languages and rules used during communication in a computer network. Introduction to networking protocols and architecture. Principles, protocols and practice, release techniques allow to create pointtopoint links while radiobased techniques, depending on the directionality of the antennas, can be used to build networks containing devices spread over a small geographical area.
In the next several paragraphs we will look at these different types of packets and what they do. Every lan uses a protocol a set of rules that governs. Also, you will learn about the most common types of protocols used by the network models while communicating one system with another. Network security is one of the tough job because none of the routing protocol cant fully secure the path. For a network between 2 and 254 hosts, the fourth octet falls on a multiple of the number of host. Transmission control protocol tcp internet protocol ip user datagram protocol udp post office protocol pop simple mail transport protocol smtp. There are many types of computer networks, the common types of area networks including those five. Top 5 network routing protocols explained lifewire. Understanding these basic network protocols with functions will help you in managing network effectively. This chapter highlights internet of things iot protocols that are operating at different layers of the networking stack, including medium access control mac layer, network layer, and session. There are several different protocols used by the internet.
Fddi makes use of token passing and transmits networks data through physical topology. This ensures optimum utilization of expensive resource and time. They can identify other routers on the network and manage information sent between different routers. These standards are developed without any formal planning. It is important to make sure that all systems on the network are configured. However, there are many other types of networks commonly found in the business world, including.

Dont forget about the pots plain old telephone system connected by. Types of area networks lan, man and wan geeksforgeeks. This tutorial explains types of network protocols and their functions in details.
A definition its worthwhile to begin by defining protocol. Computer networks can be characterized by their size as well as their purpose. This course also discusses networks in some detail. The ohio state university raj jain 2 9 layering protocols of a layer perform a similar set of functions all alternatives for a row have the same interfaces choice of protocols at a layer is independent of those of at other layers. Different types of routing protocols are applied to specific network environment. When you send a message over a wireless network, the network routing protocols are used to determine where the message is to be sent. In a computer network, the transmission of data is based on the routing protocol which selects the best routes between any two nodes. Lan local area network, wan wide area network, wlan wireless local area network, man metropolitan area network and can campus area network.
Types of virtual private network vpn and its protocols vpn stands for virtual private network vpn, that allows a user to connect to a private network over the internet securely and privately. Multiplexing is a method to combine multiple digital or analog signals into one signal over the data channel. A network is defined as a group of two or more computer systems linked together. Each packet transmitted and received over a network contains binary data ones and zeros that encode the contents of each message. Addresses, protocols, and ports this appendix provides a quick reference for ip addresses, protocols, and applications. Most protocols add a small header at the beginning of each packet to store information about the messages sender and its intended destination. One very good advantage of the fddi over some other types of network protocols is their fiber optic transmission speed of more than 100 mbps. Layering is a design principle which divides the protocol design into a number of smaller parts, each accomplishes a particular subtask, and interacts with the other parts of the protocol only in a small number of well.
