Simple Mail Transfer Protocol is the web standard for email transmission using port 25 or 587 (MSA). It conducts secured connections via SSL (SMTPS).
This is a text-based protocol wherein a mail sender communicates with its receiver through giving its instructions over TCP connection. However, it only defines the message transfer and not its content (i.e. like the physical mail envelope and not the body of the letter).

Internet Message Access Protocol is a message retrieval system common in most mail servers and email clients. It supports both offline and online operation modes and functions by transferring messages from a server to a client. IMAP does not automatically deletes messages from the server even after downloading them, unless manually done by the user.

Hypertext Transfer Protocol is the basis of data communication for the Internet and defines the standards in exchange of hypertext. It is developed to enable intermediate network components to communicate on behalf of servers and clients. HTTP is the application layer protocol within the IP suite.

PC Speak: An Abney and Associates Internet and Technology Research Lab Presents the IPv6

Internet Protocol version 6 is the most recent update of the IP, the main communications protocol that holds the whole Internet. It is created to supplant the older Internet Protocol version 4 that is still in use on most of the web traffic until today. IPv6 was formed by the IETF (Internet Engineering Task Force) as a solution for the IPv4′s imminent address shortage.

For every device that connects to the Internet, it needs an IP address — a binary number assigned to it to enable communication with other devices. And with the quick turnout of Internet-capable devices today, the current IPv4 protocol is running out of addresses that we could use.

Net providers begin warning of illegal downloads

In the first decade of the 21st century, technology made it possible to download music, movies or televisions shows from the Internet to your computer. Before this, you had to go to a music store physically and purchase an album or CD if you wanted to hear the latest from your favorite artists. With this new technology, the entire scope of how you obtain your music has changed.

But as the technology advances rapidly, unlawful downloading sites also places on a huge number. And with these, internet users who illegally download online could soon receive warning notices from the nation’s five major internet service providers. Consumers who are using peer-to-peer software are the number one target this week of the Copyright Alert System.

Transmission Control Protocol and Internet Protocol are the core of internet protocol suite as the they work together in supporting web functions.

TCP is used in email, FTP, file sharing, media streaming and the Internet in general. Because of traffic load, network congestion and other network behavior, IP packets could not be delivered properly so TCP detects possible problems to achieve successful data transmission.



PC Speak: An Abney and Associates Internet and Technology Research Lab talks about TCP / IP and other related protocols:


Abney and Associates Internet and Technology Research Lab illustrated the importance of IP addresses. IP has the responsibility of addressing packets to be transmitted across a network or across the Internet.

A complete and definitive list of programming languages ever made, with no distinction of their being high- or low-level. (Classification of PLs as low- or high-level changes over time and is highly relative to time. What is considered high-level today could be seen as low-level in the future just as assembly language was deemed high-level before.) So instead[...]

High level

High-level languages are easier for programmers to use for its closer resembalnce with human language, making it more understandable and less time-consuming compared to assembly language. Instead of assembly codes that need to be remembered or looked up each time, high-level utilizes boolean, functions, loops, arrays, objects, threads and arithmetic for maximum efficiency.
