Can you define protocol networks

Security protocols implement security over network communications by guaranteeing that data transferred over a network cannot be accessed by unauthorized users. Security is established through various means, such as via the use of passwords, authentication protocols, or data encryption.

Data can be cryptographed and protected during transportation between devices, and access can be denied to unknown or unauthorized devices or users. Network management protocols provide network governance and maintenance by defining the procedures required to operate a network. They are applied on all devices operating in a given network — such as servers, routers, and computers — to coordinate them in an efficient way. Network management protocols ensure that each device is connected to the others and to the network itself, and guarantee the stability of these connections.

They are often used for troubleshooting purposes and to assess the quality of the network connection. By: Justin Stoltzfus Contributor, Reviewer. By: Satish Balakrishnan.

Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.

Network protocols are the reason you can easily communicate with people all over the world, and thus play a critical role in modern digital communications. Neither local area networks LAN nor wide area networks WAN could function the way they do today without the use of network protocols. Network protocols take large-scale processes and break them down into small, specific tasks or functions. This occurs at every level of the network, and each function must cooperate at each level to complete the larger task at hand.

The term protocol suite refers to a set of smaller network protocols working in conjunction with each other. Network protocols are typically created according to industry standard by various networking or information technology organizations. We achieved interoperability! Like us on. Share on. What is a Network Protocol. Do you have any suggestions? With this access method, it is normal to have collisions. However, the delay caused by collisions and retransmitting is very small and does not normally effect the speed of transmission on the network.

The original Ethernet standard was developed in and had a maximum speed of 10 Mbps phenomenal at the time over coaxial cable. The Ethernet protocol allows for bus, star, or tree topologies, depending on the type of cables used and other factors.

This heavy coaxial cabling was expensive to purchase, install, and maintain, and very difficult to retrofit into existing facilities. The current standards are now built around the use of twisted pair wire. Fiber cable can also be used at this level in 10BaseFL. The Fast Ethernet protocol supports transmission up to Mbps. In addition, category 5 twisted pair or fiber optic cable is necessary. Fast Ethernet standards include:.

Gigabit Ethernet standard is a protocol that has a transmission speed of 1 Gbps Mbps. It can be used with both fiber optic cabling and copper. The Ethernet standards continue to evolve. Several very popular network protocols, commonly used in the 90's and early 21st century have now largely fallen into disuse. While you may hear terms from time to time, such as "Localtalk" Apple or "Token Ring" IBM , you will rarely find these systems still in operation.
