A protocol is a set of rules governing an operation or application. It is usually an agreed upon or standardized method for transmitting data and/or establishing communications between different devices.
Different protocols play different roles on Internet. Some examples are as follows:
- Hypertext Transfer Protocol — HTTP is a system for transferring information over the internet without any security feature. It is used to send non-sensitive information.
- Hypertext Transfer Protocol Secure — HTTPS is a system for transferring information with Secure Socket Layer (SSL) that encrypts and send information over a secure connection, making it hard to steal. It is used to send sensitive information.
