HExecutive Summary
If we go back to history, two decades ago, people used primitive message boards or emails to talk to one another and a business would communicate via text-ads or pop-ups on search engine/directory like Yahoo. (Bolman, 2015, Para 4) Then in 1997, two Stanford Ph.D. students invented an algorithm named PageRank. The PageRank calculated the importance of the website based on how often other sites would link to it. Later, with the introduction of ‘Google,’ the first wave of technology began. This invention put the modern day internet in motion. (Bolman, 2015, Para 5) This essay paper is about the modern day internet and the technological uses in our daily lives. This paper will take a closer look at how we communicate on the internet and discusses about the major network building blocks and their functions, including some vulnerabilities associated with the internet software applications.
How we communicate on the internet
In 1969, DOD’s ARPA (Advanced Research Project Agency) began an effort to develop redundant and survivable strategic communication architecture. (APUS, n.d., Week 1 Lesson) This DOD attempt gave birth to Transmission Control Protocol (TCP)/Internet Protocol (IP). TCP /IP soon found its widespread uses in the web and many networking applications (because they were very reliable and effective). TCP/IP made “web-enabled” devices possible. In addition, TCP/IP would connect to the internet (if desired) for remote
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,
Never has a communications system played so many roles in our lives--or exerted such broad influence over our thoughts--as the Internet does today.
In the present day, the development of internet causes considerable changes in social relations and people lifestyle. Internet users spend most of their life online. One of the recent trends is the development of social networks, which encourage the creation of realistic communities. In such a situation, the question concerning the impact of Internet on human being, especially on human brain and behavior arises. In this concern, views on the impact of Internet vary consistently. On the one hand, Internet is recognized as a valuable intermediate, which helps users to share and broadcast information easily. But, another view on the impact of internet, that Internet is noticed as a threat to the social life and identity of individuals
After many decades elapsed, nowadays, the quality of human life is growing better. Human beings always search and invent new things in order to meet their needs. There are not only changes in the way that people dress and behave, but also there are many changes in forms of entertainment. In the past when technologies had not developed much, people usually entertained by getting together to dance, sing, or listen to music; many of them went to a small bar in the community to drink or play cards. Today is completely distinct from the time in the past. With innovative science and modern technologies, the entertainment has become easier and more convenient for all people. Everyone can relax and amuse themselves wherever and whenever with modern electronic devices such as cell phone, tablet, LCD TV, laptop, etc. Therefore, technology has become part of our life. Many people say that we could not do anything without technology; it helps people to make work easier. In fact, technology not only impacts our daily lives, but it also has a strong influence on the criminal justice system. If law enforcement officers apply technology to their investigations, it will assist to make the investigations less difficult and more efficient. So, what has the technology already helped to make an improvement in the criminal justice field, and how has it impacted on the law enforcement?
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 TCP/IP protocols are the heart and soul of the Internet, and they describe the fundamental rules that govern all communications in the network. The original address system of the Internet is Internet Protocol version 4 (IPv4). The Internet Engineering Task Force (IETF) developed IPv6 to deal with the long-anticipated problem of IPv4 address exhaustion. However, IPv6 is not foreseen to supplant IPv4 instantaneously.
The prevalence of the internet has had a tremendous impact on American society in terms of physical health and emotional well-being. In the following pages, I will attempt to briefly highlight some of the positive and negative impacts I feel today’s internet technology has had on people living in The United States of America.
The internet matured in the 1970's as a result of the Transmission Control Protocol/Internet Protocol (TCP/IP), which is sill used today. It was adopted by the U.S. Department of Defense in 1980, and universally adopted in 1983. The usage of TCP/IP is what unites all elements of the net. Both public domain and commercial implementations of the roughly one hundred protocols of the TCP/IP protocol suite became available in the 1980's. During the early 1990's, Open Systems Interconnection (OSI) protocol implementations also became available by the end of 1991, the Internet has grown to include some 5,000 networks in over three dozen countries, serving over 700,000 host computers used be over 4,000,000 people. By December 1996, about 627,000 Internet domain names had been registered and now there are more than 30 million registered.
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
Imagine a world where geographic separation does not inhibit the social or economic mobility of people. A place where cement roads are obsolete and unnecessary and the information super highway is the only road you need to know how to navigate. Information technology becomes the glue and nails that binds our (global) society together. Development becomes a matter of installing fiber-optic wiring, cellular towers and satellite launching. World Bank projects change from road building to wire laying. Now imagine a world where there is no electricity, telephones, computers, roads or other mediums of transportation other than legs and feet. Communication exists on a face-to-face level and nothing more. An individuals’
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.
There is a big influence of technique on our daily life. Electronic devices, multimedia and computers are things we have to deal with everyday.
In today’s world 3 billion humans are on the internet but there are also 4 billion people that are not. In the beginning of my study on the future of the internet, I asked myself this question: is it possible that everyone could be online and globally connected? Then I asked myself how, if everyone is online, the future of the internet change the experience of everyday life? Looking back, the internet is still a relatively new phenomenon as it was first created back in the 1960’s by a computer scientist named J.C.R Licklider. He envisioned a network of computers, called the galactic network, which would allow humans to be able to share information instantly. Overtime this is how the internet developed, as many of these networks that shared
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.
Following the success of Netscape and its web browser, Internet became a resource and communication platform idolized by many IT students in the universities. What started off as a hobby-cum-research[1] work by Jerry Yang (now Chief of Yahoo!) and David Filo (Co-founder of Yahoo!) for their Ph.D. dissertations; has evolved and became an Internet sensation over time. What they did was to compile all their favourite web links to form an online directory for easy navigation in the World Wide Web. The duo’s work immediately garnered a lot of attention from many surfers in the Internet world and before they realized it, Yahoo! became one of the most highly visited websites of all time. The duo saw the
