Web protocols

In the world of technology, a large number of users communicate with different devices in
different languages. This also includes the many ways they transfer data along with the
different programs they implement. Therefore, worldwide communication would not be
possible if there were no fixed “standards” that would govern the way the user communicates
for data as well as the way our devices handle this data, we are talking about protocols. Internet
protocols are a set of rules that control communication and exchange of data over the Internet.
Both sender and receiver must follow the same protocols to communicate data.

Types of protocols:

• HTTP (Hyper Text Transfer Protocol)
• HTTPS (Hyper Text Transfer Protocol Secure)
• FTP (File Transfer Protocol)
• SMTP (Simple Mail Transfer Protocol)

HTTPS (Hyper Text Transfer Protocol Secure) :

HTTPS It is a secure version of the http protocol that uses SSL/TLS for authentication and
encryption. It uses port 443 by default instead of port 80 in HTTP. Sensitive data such as
banking information, credit card numbers, and login data to https are transferred securely via
https. Internet. This protocol is especially essential when securing online activities such as
banking, remote work, and shopping, and given the importance that https represents, all sites
have come to rely on it, whether to exchange sensitive data with users or not.
