Define the following concepts: computer network, network architecture, protocol, and multilayer protocol.

 Computer network:

 The computer networking is basically defined as the set of various connected computer together in the system. It is basically connected various hardware devices together for the communication that facilitates the various file and resource sharing among the users.

There are many types of computer networking that are:

Network architecture:

Network architecture can be characterized as the total structure of an association's PC arrange. Networking design it incorporates equipment segments utilized for correspondence, cabling and gadget types, organize format and topologies, physical and remote associations, actualized territories and feasible arrangements.

This design is constantly structured by a system supervisor/head with coordination of system specialists and other plan engineers.

Protocol:

 Protocol is the standard form of rules that basically allow the various electronic devices for communication. It is basically characterizes the  guidelines and shows for correspondence between system gadgets.

Conventions typically utilized for PC systems administration and all by and large use parcel changing strategies to send and get messages as bundles.

There are many types of the protocol that are:

Multi layer protocol:

 Multi layer protocol is the arrangement of the correspondence conventions give measures that enable various frameworks to speak with one another DNP3 is a lot of systems administration conventions structured explicitly for use in a class of frameworks known as supervisory control and information procurement, or SCADA framework.
