There are different types of network protocols utilized for proper communications between computers. Network protocols are rules and guidelines that regulate the access method, data transfer, physical typologies, and other characteristics of computer networks.
Common types of Network Protocols
* Token Ring
* Local Talk
This is the most common of all types of network protocols for the connection of local network. It can transmit data as high as 200 mega bytes per second (Mbps). While other network protocols can transmit data in large packages of varying sizes, the ATM transmits its own data in small bits of equal sizes. It works with a wide range of media types like imaging, CD quality audio, and videos. Its transfer medium is equally compatible with both twisted pair cables and fiber optics. ATM is most frequently used to connect local networks and is also used by ISPs who want to provide high speed internet access to their clients. It’s decreasing installation costs means that the network will soon become the Go-to network for people seeking for high speed local area network connections.
Ethernet networks are the most common types of network protocols available today. It makes use of an access network known as CSMA/CD which ensures that each of the connected computers listen to the command prompt of the cable before sending ionformation.
The computer transmits only when there are no modes on the network. There are cases where two computers will try to transmit simultaneously. When this occurs, each of the network computers pulls back and waits for a certain period of time before trying to access the cable. Collusion of computers is normal with these types of network protocols, and it doesn’t necessarily affect the network’s transmission speed. The Ethernet protocol works well in tree, star, or bus topologies. Transmitted data can pass through fiber optic, coaxial, twisted pair, or wireless access point at more than 500 Mbps.
These types of network protocols are primarily used to connect local area networks that have long distances between them. FDDI makes use of token passing and transmits networks data through physical topology. 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.
Token ring as the product of IBM technology was developed in the 1980s and uses token-passing as its access method. In these types of network protocols, a logical ring is used to transmit signals from one computer to the other. In a situation where, a computer doesn’t readily have information, the token ring moves on to other computers. The token can transmit at a speed of 5Mbps to 15Mbps, and is increasingly becoming less popular as a result of the increasing use of the Ethernet network protocol.
This one was introduced by Apple computer and uses a transmitting method known as CSMA/CD. It was developed to be used with the Macintosh operating systems and have uses twisted cables for connecting computers.
