What Is The Internet?

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,

TCP/IP stands for transmission control protocol/ internet protocol. TCP/IP is responsible for how devices like computers should be connected over the internet and how data should be transmitted from one computer to another. The IP essentially functions by exchanging set of information which is called packets. Packets are short structures of bytes which contains of headers and body. The body only contains the application data. The headers keep on sending the information back on forth until the data is sent to the right destination, the packets can usually send in the wrong order this means that the data was crashed by the firewall or data was destroyed while sending information.TCP is the transmission communication protocol which delivers packets to the accurate to destination.

The term "Internet" (often referred to as "global network", "global network" or "Network") - implies a global system of arbitrarily interconnected computer networks, which are used to store and freely exchange data, information and knowledge. The information space that constitutes the Internet is the physical basis of the world wide web (WWW - World Wide Web) and many other data transmission systems [58, p.

World wide web (WWW) created by Tim Burners-Lee is the building blocks of what we know as the internet today. There has been a continuous growth even at present, versions of the web are adapting to contribute to user satisfaction. It is a surface for virtual communication where data is transfers wth hypertext document. Overlooking the formation of WWW has 3 stages: "Web of document(Web 1.0), Web of people (Web2.0) and Web of data (Web3.0)" (Choudhury, 2014)

Well-known communications protocols are Ethernet, a hardware and Link standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.

Applications that are used by most businesses uses internet’s main program, TCP/IP through the client/server model. For example, when you check your bank account from your computer, a client program in your computer forwards a request to a server program at the bank. That program may in turn forward a request to its own client program, which then sends a request to a database server at another bank computer. Once your account balance has been retrieved from the database, it is returned back to the bank data client, which in

The world wide web otherwise called the internet came about in the 1960s and was primary used for researchers and academia. But since the 1990s, the internet has had that revolutionary effect on the culture and commerce in our society. This includes communication by email, instant messaging, internet phone calls. In addition, there is also the world wide web with discussion forums, social networking sites, and online shopping sites which several amount of people, despite their generation have utilized to their own benefit. However, these are the icing on the internet cake. Now, the internet since its its inception remains one of the world's most revolutionary piece of technology. Emits its positive, there are many negatives and destruction

Breakdown of the word ‘Internet’ would be Inter- Connected computer networks. The internet is made up of millions of computers connected together. There is only one network. The Internet is a global computer network that provides information and other facilities to people all around the world through protocols. The Internet could be accesses from different devices via different networks. The Internet is used daily in people’s lives. At school; for educational purposes, at work; access to client profile and other resources, universities; researching facilities and at home. The internet consists of different facilities, such

The advent of the Internet started when the U.S. Government’s Department of Defense collaborated with some U.S. universities creating the Advanced Research Projects Agency (ARPA). This was driven by the cold war between the West and the Soviet Union at the time where fear of traditional communications breakdown may occur and phones stop working prompting the need for a backup plan. Mainframe to mainframe (No PCs were made yet) direct communication or in other words, a networking system that does not get affected, was created where everyone accesses data from anywhere . The new name for that is the ARPANET.

When it comes to the ever-evolving world we live in today, the future of technology and the Internet and the way in which it will be embedded into our lives is inevitable. The transformation of the Internet has definitely evolved within the past decade, this shows how much potential the Internet has to further develop. Web 2.0 is currently what is commonly used on the Internet and it is predicted that Web 3.0 will be a new era for the web. Web 3.0 can be defined as an online environment integrating users’ data to create new meaning (Barassi, 2012, p.1270).

Working with Internet does not mean just browsing www and sending and receiving e-mails. The Basic Structure of the Internet was developed through last 30 years of existence of the Internet. The Internet is a heterogeneous worldwide network consisting of a large number of host computers and local area networks. The Internet uses the TCP/IP suite of protocols. This allows the integration of a large number of different computers into one single network with highly efficient communication between them. This way, the user can access information on all kinds of host computers from a desktop PC, Macintosh, or

They wanted to devise an inter-networking system (or internet) whereby different networks could ‘talk’ to one another. Arpanet devised TCP/IP (Transmission Control Protocol/Internet Protocol). This was a set of rules for communication between networks. The Internet became a network of networks. Only the military stayed outside of this for security reasons. In 1988, there were 50,000 computers attached to the Internet. By 1991, there were 1 million. However, it was difficult to access the information contained on the Internet as the system had little organisation. This problem was solved by Tim Berners-Lee, a British scientist studying at a research facility in Switzerland. He invented a method of organising information which he called the world-wide-web (www). His system linked documents from different sources and guided users to related information. The www was first used by the public in 1991 and it allowed the transfer of text, sound, images and video clips. Above all else, it was simple to use.

In 1965 another M.I.T. scientist developed a way of sending information from one computer to another that he called packet switching. This was a precaution taken that saved the data, breaks it into blocks and sends it whatever route you wanted keeping the information secure unlike the scare they had with the communication of the phone line (“The Invention”). By the end of the 1970s, a computer scientist named Vinton Cerf had begun to solve this problem of a single worldwide internet by developing a way for all of the computers on all of the world’s mini-networks to be able to interact with any other network around the world. He called his invention “Transmission Control Protocol,” or TCP (“The Invention”). Cerf’s protocol transformed the Internet into a worldwide network. Throughout the 1980s, researchers and scientists used it to send information and different files of data from one computer to another. However, in 1991 the Internet changed once more. That same year, a computer programmer in Switzerland named Tim Berners-Lee introduced the World Wide Web. An Internet that was not simply a way to send information from one place to another but was itself a “web” of information that anyone on the Internet could access. Berners-Lee created the Internet that we know and use today (“The Invention”). Different browsers would be created throughout time such as Google, Bing and Yahoo just to name a few as a way to search any

The internet is also called ‘The Net’. It has a collection of inter-connected networks that are globally spread. In short, internet is a network of global system of computer network. Millions of computers are inter-connected by the internet forming a network where every single computer could communicate with one another. For example in a university computer lab, if there were no network, all the computers need to have their own personal printer. But now, with network, we could cut cost by getting one printer and connect all the computers in the computer lab to the printer through network.

The Internet and World Wide Web are commonly used words among people today. As a college student especially, the Web and Internet play a huge part of life. What is sometimes tough to realize though is the newness of the Internet and the Web. Because the two have become such a huge part of life, it is shocking to consider that the Internet itself has only been in existence for the past thirty years or so. It is important to understand the history of the Internet and the creation of the Web to better prepare for the future of the two and to ensure that the use of the resources is maximized, focused, and beneficial to all mankind.
