Network Protocols

What is a Network Protocol

A method is a set of regulations that controls the marketing and sales communications between pcs on a system. These regulations include suggestions that control the following features of a network: access method, granted physical topologies, types of electrical circuitry, and pace of information.

Types of Network Protocols


The Ethernet technique is by far the most widely used. Ethernet uses an accessibility technique called CSMA/CD (Carrier Sense Several Access/Collision Detection). This is a system where each personal pc concentrates to the cord before giving anything through the system. If the system is clear, laptop will send. If some other node is already shifting on the cord, laptop will wait and try again when the line is clear. Sometimes, two pcs attempt to give at the same fast. When this happens an impact takes place. Each personal pc then supports off and stays a unique period before seeking to retransmit. With this accessibility technique, it is normal to have accidents. However, the delay due to accidents and retransmitting is very small and does not normally affect the pace of indication on the system.

The Ethernet technique allows for straight line bus, celebrity, or pine topologies. Data can be given over wifi accessibility points, complicated pair, coaxial, or fiber content optic cord at a pace of 10 Megabyte per second up to 1000 Megabyte per second.

Local Talk

To allow for a greater pace of indication, the Ethernet method has designed a new normal that can handle 100 Megabyte per second. This is generally known as Quick Ethernet. Quick Ethernet demands the use of different, more expensive system concentrators/hubs and system screen credit cards. In addition, group 5 complicated couple or fiber content optic cords is necessary. Quick Ethernet is becoming common in universities that have been lately sent.

Token Ring

The Small Band method was developed by IBM in the mid-1980s. The access method used involves token-passing. In Small Band, the computers are connected so that the signal travels around the network from one personal pc to another in a logical gemstone. A single electronic token moves around the gemstone from one personal pc to the next. If a personal pc does not have information to give, it simply passes the token on to the next workstation. If a personal pc wishes to give and receives an empty token, it attaches information to the token. The token then proceeds around the gemstone until it comes to laptop for which the information is meant. At this point, the information is captured by the receiving personal pc. The Small Band method requires a star-wired gemstone using twisted pair or fiber optic cable. It can operate at transmission speeds of 4 Megabyte per second or 16 Megabyte per second. Due to the increasing popularity of Ethernet, the use of Small Band in school environments has decreased.


Fiber content Allocated Information Screen (FDDI) is a system method that is used mainly to interconnect two or more community systems, often over large ranges. The accessibility method used by FDDI includes token-passing. FDDI uses a double band actual topology. Indication normally takes place on one of the rings; however, if a bust takes place, the system keeps information shifting by instantly using servings of the second band to make a new total band. A significant benefit of FDDI is pace. It performs over fiber optic cord at 100 Megabyte per second.


Asynchronous Transport Method (ATM) is a system method that sends information at a pace of 155 Megabyte per second and greater. ATM works by shifting all information in small packages of a resolved size; whereas, other methods transfer diverse measurements packages. ATM can handle a range of press such as video, CD-quality music, and image. ATM has a celebrity topology, which can work with fiber content optic as well as complicated couple cord.

ATM is most often used to interconnect two or more community systems. It is also regularly used by Web Service Companies to use high-speed use of the Web for their customers. As ATM technological innovation becomes more cost-effective, it will provide another option for developing quicker community systems.
