An Explanation of How the Internet Works Essay

The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP).

But how does it work? The internet, based on the concept of “packet switching”, involves the travelling of small packets of data over one or more networks (Frenzel, 2013). This can be compared to “electronic postcards”, meaning that “a computer generates a piece of data and flings it into the net, just like the postal system, except 100 million times faster” (Cerf, 2013). This concept allows one computer to speak to many different computers around the network by sending out these “electronic postcards”. However, before these networks can work seamlessly together, they must use a common protocol, or set of rules for transmitting and receiving these packets of data. There are several protocols currently in use, including the OSI Model, the TCP/IP Model, UDP, HTTP, and FDP (Mitchell, 2014), but the most commonly used is Transmission Control Protocol/Internet Protocol (TCP/IP) (Gilmer, 2011). Even as early as 1977, TCP/IP was being used by other networks to link to ARPANET (Kozierok,

The internet layer is built up of four core protocols: IP, IGMP, ICMP and ARP. Internet protocol (IP) is responsible for routing, IP addressing and breakdown/reassembly of data packets, address resolution protocol (ARP) is responsible for mapping an IP address to a device on the local network, internet control message protocol (ICMP) provides diagnostic information and error reports on lost packets, internet group management protocol (IGMP) controls who receives IP datagrams in a single transmission. The transport layer is built up of two core protocols: TCP and UDP. Transmission control protocol (TCP) sequences and acknowledges packets sent and their recovery when lost in transmission allowing the computer to make and maintain network conversations where applications exchange data, defined as a connection-oriented protocol meaning the connection is maintained until the programs has finished exchanging data. User datagram protocol (UDP) This is used to transfer small amounts of data when the use of error correction isn’t needed increasing the speed of the transmission, common in multi-player video games as the user will not need to receive packets of past events in the game so the error correction featured in (TCP) would be

When dealing with emails, you have a IMAP, a POP3 or a SMTP, protocols. First, we have a IMAP, which is similar to a POP3 because they are both used to read mails from a remote server. The IMAP is considered more advanced than a POP3. Then you have a SMTP, which is only used for sending emails. For example, if you plan to set up an email server such as hMailServer, you must know what each protocol is used for. Each protocol is considered to be a specific set of communication rules between computers. Now, we will take a closer look at each protocol specifically.

For example the way a Router communicates to a computer is through an IP address which is assigned by the router which will then find the computer and transmit information to and from the computer.

TCP/IP is the transport/network layer protocol we use on the internet. Many BN’S, MAN’s and WAN’s rely on it. This is because it is relatively efficient, and transmission has few errors. Any errors that are found, are checked and so large files can be sent even in the most unsafe network and the data will still be unchanged. TCP/IP is very compatible with a number of data link protocols as well.

The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was

The data is then sent back through the system to the original user. The information that is on the data coming back could have came from a wide array of sources such as books, financial markets, embedded chips or even made up by someone trying to fool the user. The History? The Internet is first

The Internet - The Good, the Bad, and the Ugly The internet is a computer based global information system. It is composed of many interconnected computer networks. Each network may link thousands of computers enabling them to share information. The internet has brought a transformation in many aspects of life.

Perhaps one of the greatest inventions of out time is the Internet. Without a doubt, the net has had a profound effect on almost every aspect of our lives. The formation of the Internet has changed the way we do business, communicate, entertain, retrieve information, and even educate ourselves. Nevertheless, the Internet might have never materialized if it had not been for some innovated thinkers from the Advanced Research Project Agency, who created "ARPANET." In collaboration with several educational and research institutions, the agency created the packet-switching technologies that form the basis of the Internet today.

Over the next 10 years, we will see a change in technology, and the Internet. Things will continue to progress, and fundamental changes will easily be defined. Technologies have revolutionized how people spread and consume information; these changes will redefine who we are as consumers, merchants, and individuals. With the expansion of computers and the Internet connectivity, people are able to share more of their lives with family and friends. Technology has offered the world so many different services, which include emailing, instant messaging, search engines, blogs, and Wikipedia. These services have changed the way we communicate with others, our knowledge, and the way we conduct business. With the increasing usage of the Internet, developers continue to find ways to improve technology and the way we utilize the Internet. Technology has a wide range of different aspects and concepts, which includes protocols. There has to be rules, and objectives in any and everything we do, and protocols governs communications, errors, detections, messages, and speed. There are three technology concepts behind the Internet, and they are packet switching, Transmission Control Protocol/Internet Protocol (TCP/IP) communications

In this essay I will analyze how and why the Internet distinctively differs from other ordinary kinds of networks; specifically, I will compare it to the London Underground system (reference to the network analysis of the 2005 London underground attack, Ferenc 2008. Therefore, in this essay I will analyze and discuss the extent to which the Internet is widely different to other networks; I will support my point using some leading scholar’s theories and experimental results.

In today’s world Internet has become one of the most important mediums of communication. It has become the lifeline of our survival. It has removed the entire social, economic and physical barrier and has immense effect on our day to day activity.

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.

Internet is a global network, connecting thousands of host servers worldwide. The United States Department of Defense established it in the beginning of the 1960¡¯s. Today, there are now 10 to 20 million people using an Internet comprised of more than 30,000 networks spread out over 78 nations all over the world.
