TCP/IP stands for Transmission Control Protocol / Internet
Protocol. It defines how electronic devices (like computers) should be
connected over the Internet, and how data should be transmitted between them.
TCP - Transmission Control Protocol
TCP is responsible for breaking data down into small packets before they can be set over a network, and for assembling the packets again when they arrive.
IP - Internet Protocol
IP takes care of the communication between computers. It is responsible for addressing, sending and receiving the data packets over the Internet.
HTTP - Hyper Text Transfer Protocol
HTTP takes care of the communication between a web server and a web browser. HTTP is used for sending requests from a web client (a browser) to a web server, returning web content (web pages) from the server back to the client.
HTTPS - Secure HTTP
HTTPS takes care of secure communication between a web server and a web browser. HTTPS typically handles credit card transactions and other sensitive data.
FTP - File Transfer Protocol
FTP takes care of transmission of files between computers.
Names used for TCP/IP addresses are called domain names.
SMTP - Simple Mail Transfer Protocol
SMTP takes care of sending emails. Often emails are sent to an email server (SMTP server), then to other servers, and finally to its destination. SMTP can only transmit pure text. It cannot transmit binary data like pictures, sounds or movies.
MIME - Multi-purpose Internet Mail Extensions
The MIME protocol lets SMTP transmit multimedia files including voice, audio, and binary data across TCP/IP networks. The MIME protocol converts binary data to pure text, before it is sent.
POP - Post Office Protocol
The POP protocol is used by email programs to retrieve emails from an email server. If your email program uses POP, all your emails are downloaded to your email program (also called email client), each time it connects to your email server.
IMAP - Internet Message Access Protocol
The IMAP protocol works much like the POP protocol. The main difference is that the IMAP protocol will not automatically download all your emails each time your email program connects to your email server.
The IMAP protocol allows you to look through your email messages at the email server before you download them. With IMAP you can choose to download your messages or just delete them. This way IMAP is perfect if you need to connect to your email server from different locations, but only want to download your messages when you are back in your office.

IP is Connection-Less
TCP/IP Protocol for WEB
Web browsers and servers use TCP/IP protocols to connect to the Internet. Common TCP/IP protocols are:HTTP - Hyper Text Transfer Protocol
HTTP takes care of the communication between a web server and a web browser. HTTP is used for sending requests from a web client (a browser) to a web server, returning web content (web pages) from the server back to the client.
HTTPS - Secure HTTP
HTTPS takes care of secure communication between a web server and a web browser. HTTPS typically handles credit card transactions and other sensitive data.
FTP - File Transfer Protocol
FTP takes care of transmission of files between computers.
Domain Names
A name is much easier to remember than a 12 digit number.Names used for TCP/IP addresses are called domain names.
TCP/IP Protocols for Email
E-mail programs use TCP/IP for sending and receiving e-mails. The TCP/IP protocols for email are:SMTP - Simple Mail Transfer Protocol
SMTP takes care of sending emails. Often emails are sent to an email server (SMTP server), then to other servers, and finally to its destination. SMTP can only transmit pure text. It cannot transmit binary data like pictures, sounds or movies.
MIME - Multi-purpose Internet Mail Extensions
