What do you know about Protocols? Explain Different types of Protocols?

Question

Accepted Answer

Protocols are a set of rules that govern the communication between devices or systems.

Protocols define the format, timing, sequencing, and error checking of messages exchanged between devices.
Different types of protocols include network protocols (TCP/IP, HTTP, FTP), communication protocols (RS-232, USB, Bluetooth), and application protocols (SMTP, POP3, IMAP).
Network protocols govern the communication between devices on a network, while communication protocols govern the communication between devices connected by a cable or wireless link.
Application protocols are used by specific applications to exchange data, such as email or file transfer.
Protocols can be proprietary or open standards, and can be implemented in hardware or software.
Examples of protocols include TCP/IP for internet communication, Bluetooth for wireless communication, and SMTP for email communication.
