What is the difference between network protocols?

Networks are set up with a protocol hierarchy that divides the communication task into several layers. A protocol is a set of rules for communication within a layer. A service is what the layer provides to the layer above it through an interface. Protocols at one layer are unaware of issues at another layer.

Why are protocols important in network communication?

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.

How many protocols are there in networking?

Generally speaking, there are three types of protocols in networking — communication, such as Ethernet; management, such as Simple Mail Transfer Protocol (SMTP); and security, such as Secure Shell, or SSH.

Why are there different network protocols?

Communication. Communication protocols allow different network devices to communicate with each other. They are used in both analog and digital communications and can be used for important processes, ranging from transferring files between devices to accessing the internet.

What is protocol and different types of protocol?

There are three main types of network protocols. These include network management protocols, network communication protocols and network security protocols: Communication protocols include basic data communication tools like TCP/IP and HTTP.

What is the difference between protocol and architecture?

Protocols define how diverse modules interact, and architecture defines how sets of protocols are organized. Architecture usually involves specification of protocols (rules of interaction) more than modules (which obey protocols).
