Social Legal and Economic Impact of Ebusiness in Ireland

The beginning of the Internet is well known. It was a United States Defense research program named ARPANET. The internal structure of ARPA that reared the network development during its first years is not as well known. Inventing the Internet explains how the little agency was created in 1958 to respond to the Soviets' successful launch of the world's first artificial satellite. ARPA did not own a laboratory.

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,

ii. Do a good job on the project. I worked countless hours working to prefect this project, and feel as if I deserve some encouragement.

A) It is your responsibility to read the assignment carefully and make sure you understand what you need to do and what you should hand in. If you are not sure, check with

4.How would you change the approach if you carried out the activity again ? How?

You will discover different network topologies and different types of networks: LANs, WANs, and internetworks (internets). The concept of switching is discussed to show how small networks can be combined to create larger ones. You will learn about the Internet: its early history, the birth of the Internet, and the issues related to the Internet today. This module covers standards and standards organizations.

b. Another thing that I did well was asking questions. I didn’t ask a ton of questions but I always asked when I wasn’t clear on something and this helped me a lot. For example, on the unit 2 assignment if I hadn’t asked about the format my essay would have been completely incorrect. After asking for clarity I was extremely satisfied with my end product and it was the correct

5. The content flows logically and demonstrates an understanding of the topic (up to 10 points)

2) Review your homework from Week 1. What progress did you make on your course

4.Everybody bring your own book to school. If someone forgets his book, there will be a loss of points.

The two authors follow the story from the conception of the idea of "packet switching" in the early 1960s to the creation and development of the Internet. We see how one idea led to another and how the intelligent people around the circumstances influenced the developments.

network (ARPANET) meant to promote the sharing of super-computers amongst researchers in the United States.” (Kristula, pg 68). Through the next couple years there were talks of about how this network could come into the cooperate world. In 1969 researchers at four US campuses created the first hosts of the ARPANET. They connected the Stanford Research Institute, UCLA, UC Santa Barbara, and the University of Utah. The ARPANET was a success from the very beginning. Although originally designed to allow scientists to share data and access remote computers, email quickly became the most popular application. The ARPANET became a high-speed digital post office as people use it to collaborate on research projects and discuss topics of various interests. In 1971 the ARPANET grows to 23 hosts connecting universities and government research centers around the country. In 1972, the Inter-Networking Working Group becomes

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.

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.
