Protocol

A set of rules that defines how data is transmitted and received over a network.

Definition

Standard

An agreed-upon specification that ensures interoperability between different systems and devices.

Note

Protocols and standards are essential for the functioning of the World Wide Web.

Key Protocols and Standards

Hypertext Transfer Protocol (HTTP):
1. Defines how web browsers and servers communicate.
2. HTTPS is a secure version that encrypts data.
Transmission Control Protocol/Internet Protocol (TCP/IP):
1. The foundational protocol suite for the internet, ensuring reliable data transmission.
Domain Name System (DNS):
1. Translates human-readable domain names into IP addresses.
File Transfer Protocol (FTP):
1. Used for transferring files between computers on a network.
Simple Mail Transfer Protocol (SMTP):
1. Handles the sending of emails.

Importance of Protocols and Standards

Interoperability:
1. Ensures that devices and applications from different manufacturers can work together seamlessly.

What is a protocol?

Introduction to Protocols and Standards

A protocol is a set of rules that defines how data is transmitted and received over a network.
A standard is an agreed-upon specification that ensures interoperability between different systems and devices.

AnalogyThink of protocols as the grammar of a language and standards as the dictionary that everyone agrees to use.

ExampleWhen you send an email, your computer follows the SMTP protocol to ensure the message is delivered correctly.
