TCP/IP - The Internet protocol suite is the computer
networking model and set of communications protocols used on the Internet and
similar computer networks. It is commonly known as TCP/IP, because it’s most
important protocols.
TCP/IP provides end-to-end connectivity specifying how data
should be packetized, addressed, transmitted, routed and received at the
destination. This functionality is organized into four abstraction layers which
are used to sort all related protocols according to the scope of networking
involved
HTTP - The Hypertext
Transfer Protocol (HTTP) is an application protocol for distributed,
collaborative, hypermedia information systems. HTTP is the foundation of data
communication for the World Wide Web. Hypertext is structured text that uses
logical links (hyperlinks) between nodes containing text.
HTTPS – HTTPS is a
protocol for secure communication over a computer network which is widely used
on the Internet. HTTPS consists of communication over Hypertext Transfer
Protocol (HTTP) within a connection encrypted by Transport Layer Security or
its predecessor, Secure Sockets Layer. The main motivation for HTTPS is
authentication of the visited website and to protect the privacy and integrity
of the exchanged data.
SMPT - Simple Mail Transfer Protocol (SMTP) is an Internet
standard for electronic mail (e-mail) transmission. First defined by RFC 821 in
1982, it was last updated in 2008 with the Extended SMTP additions by RFC 5321
- which is the protocol in widespread use today. SMTP by default uses TCP port
25.
