    The Program and System Information Protocol (PSIP) is the MPEG (a video and audio industry group) and privately defined program-specific information originally defined by General Instrument for the DigiCipher 2 system and later extended for the ATSC digital television system for carrying metadata about each channel in the broadcast MPEG transport stream of a television station and for publishing information about television programs so that viewers can select what to watch by title and ...

    In modern protocol design, protocols are layered to form a protocol stack. Layering is a design principle that divides the protocol design task into smaller steps, each of which accomplishes a specific part, interacting with the other parts of the protocol only in a small number of well-defined ways.

    The Internet Protocol gets information from a source computer to a destination computer. It sends this information in the form of packets. There are two versions of the Internet Protocol currently in use: IPv4 and IPv6, with IPv4 being the version most used. IP also gives computers an IP addressto identify each other, much like a typical physical address. IP is the primary protocol in the Internet Layer of the Internet Protocol Suite, which is a set of communications protocols consisting of seven abstraction layers (see OSI model), The main purpose and task of IP is the delivery of datagrams from the source host (source computer) to the destination host (receiving computer) based on their addresses. To achieve this, IP includes methods and structures for putting tags (address information, which is part of metadata) within datagrams. The process of putting these tags on datagrams is called encapsulation.Think of an anology with the postal system. IP is similar to the U.S. Postal Syst...

    ARPANET, the early ancestor of the internet, was designed to survive a nuclear war. If one computer was destroyed, communication between all the other computers would still work. Computer networks still follow this same design. Computers talking to each other handle the "smart" functions to simplify computer networks. The end nodes will check for errors instead of a central authority. Keeping the "smart" things on the end computers or nodesfollows the end-to-end principle. The Internet Protocol sends packets out without ensuring they arrive safely. This is best-effort delivery, and is unreliable. Packets could get messed up, lost, duplicated, or received out of order. Higher level protocols like the Transmission Control Protocol (TCP) ensure packets are delivered correctly. IP is also connectionless, so it does not keep track of communications. Internet Protocol Version 4 (IPv4) uses a checksumto check for errors in an IP header. Every checksum is unique to a source/destination comb...

    In 1974, the Institute of Electrical and Electronics Engineers published a paper called "A Protocol for Packet Network Intercommunication". The paper described a way for computers to talk to each other using Packet Switching. A big part of this idea was the "Transmission Control Program". The Transmission Control Program was too big, so it split into TCP and IP. This model is now called the DoD Internet Model and Internet Protocol Suite, or the TCP/IP Model. Versions 0 to 3 of IP were experimental, and used between 1977 and 1979. IPv4 addresses will run out, because the number of possible addresses is finite. To fix this, the IEEE made IPv6 which had even more addresses. While IPv4 has 4.3 Billion addresses, IPv6 has 340 undecillionof them. This means we will never run out of IPv6 addresses. IPv5 was reserved for the Internet Stream Protocol, which was only used experimentally.

Electronic mail (or e-mail or email) is an Internet service that allows people who have an e-mail address ( accounts) to send and receive electronic letters. Those are much like postal letters, except that they are delivered much faster than snail mail when sending over long distances, and are usually free.

    Imagine a life without the Internet. You can't, can you? No. Just today, I told one of my colleagues that the human race has grown so dependent on the Internet, and when, for example, a network is down, you cannot do any work. The Internet is good, but it is very scary to come to a realization of our need for the Internet. Today, I will quickly show you how to create an FTP program in Visual Basic. Let's get technical—but not too much! In an earlier article, I spoke about UDP and Visual Basic. In this article, I spoke about all the protocols that make the Internet what it is. That just covered the communication part; let's explore the real Internet now.

    The Internet is a global system of interconnected computer networks that use TCP/IP to link trillions of devices worldwide linked by an array of electronic, wireless, and optical networking technologies. Okay, Captain Obvious (that's me), let's move on! For a good and proper lesson on the Internet and its origins, this Wikipediaarticle will be helpful. I am just going to highlight Protocols and specifically the FTP Protocol here.

    A Protocol, or rather a Communication Protocol, is a set of rules that enables two or more entities to transmit information to one another.

    Some of the most common Protocols are as follows: 1. TCP 2. IP 3. UDP 4. POP 5. SMTP 6. HTTP 7. FTP For more information regarding these protocols, read through this article of mine.

    You can most likely already deduce that we will cover four FTP operations today. These are: 1. Uploadinga file to an FTP Server 2. Downloadinga file from an FTP Server 3. Deletinga file from an FTP Server 4. Renaminga file on an FTP Server Before we can do any of those, we need to import the necessary namespaces into our project. Add them now: The System.Netnamespace enables you to work with Internet protocols, Internet Web pages, and Internet resources. The System.IOnamespace enables you to work with any file.

    Knowing when and how to work with the Internet's many different protocols is essential in any decent application.
