Protocol Testing:-
What is Protocol in a software industry?
When computer communicates with each other, there is a common arrangement of rules and conditions that every computer needs to follow. As such, protocols decide how data/information are transmitted between computing devices and over networks.
Protocols are characterized into two categories routed protocols and a routing protocols.
Routed Protocols: Routed protocols can be utilized to send the user information/data starting with one network to another network. It carries user traffic like messages, web-activity, file transfers, e-mails etc. These protocols are IP, IPX, and AppleTalk.
Routing Protocols: Routing protocols are network protocols that decide routes for switches. It is just utilized between switches/routers. For instance RIP, IGRP, EIGRP, and so on.
In basic terms, router is similar to a transport utilized for transportation while directing/routing protocols are signs out and about on the road.
Based on the sort of communication different protocols are utilized.
Types/Sorts of computer protocols:-
Types/Sorts of Protocols |
Purpose of Protocols |
TCP/IP |
It is utilized to send data/information in little packets over Internet |
UDP/ICMP |
It is utilized to send little amount of data/information in data-packets over web/internet |
POP3 and SMTP |
It is utilized for sending and receiving mail |
Hypertext Transfer Protocol |
It is utilized to transfer HTML page in encrypted structure to give security to delicate data |
FTP |
It is utilized for transporting records over a network starting with one hub/node to another |
* TCP/IP-Transmission Control Protocol/Internet protocol, UDP/ICMP-User Datagram Protocol/Internet Control Message Protocol, POP3/SMTP-Post Office Protocol/Simple Mail Transfer Protocol, HTTP-Hyper Text Transfer Protocol, FTP-File Transfer Protocol
Different sorts of network Protocols (L2 and L3):-
The OSI model has all out 7 layer of system/network communication, in which layer 2 and layer 3 are exceptionally crucial.
Layer 2: It is an data join/link layer. Macintosh address, Ethernet, Token Ring, and Frame Relay are all examples of Data connection/link layer.
Layer 3: It is a network layer that decides the best available way in the network for communication. IP location is an example of layer3.
