Broadband, DSL, and the Race for Internet Connectivity
Abstract This paper discusses current technologies and trends relating to Internet connectivity. Broadband cable, DSL, and fixed wireless are examined. Issues addressed relating to these technologies are the potential for providers to favor specific content on broadband cable and the 'digital divide' or the trend of inaccessibility of the internet in poor and rural areas.
In recent years, the Internet has radically changed both our economic and social institutions. The driving force behind the Internet has been increasingly cheap, fast, and reliable connections between distant machines. As Internet connectivity increases, internetworking can

These issues are discussed in depth in this paper, but first the high-speed technologies are introduced.
Means of High Speed Access
There are currently two competing high-speed connection technologies, DSL and cable modems. DSL uses existing copper phone lines to reach extraordinary transmission speeds. At central offices, which are connected to the Internet via high speed fiber-optic connections, a DSLAM machine routes network traffic along the pre-existing dedicated copper phone lines to consumers. This has the apparent advantage of using pre-existing wiring. There are, however, difficulties. The broadband signal has a limited 3-mile range on copper wire, so DSL is only available in areas near a central office. Also, some newer telephone wires are not compatible with the DSLAM technology. The result is that while DSL may work well in heavily populated areas, but it is far less practical in rural areas.1
Cable broadband uses a modified version of cable TV lines to transmit data at high speed. A cable modem attached to this line allows computers and TVs to access the Internet. This method, developed slightly before DSL, is currently the most popular choice amongst consumers, but there are problems. Standard cable lines were designed for one-way transmission and must be replaced with two-way lines
The internet has revolutionized the modern world like no other invention has before, except perhaps, electricity. The internet allows sharing and collaboration to take place between people on opposite sides of the globe. Vinton G. Cerf, often called the “Father of the Internet”, admits that when the original idea of an “intranet” was in its infancy, there was no possible way to imagine all of the ways we would come to use it (NDTV, 2013).
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.
Internet works and how its used for high speed Internet access. The article also discusses
Internetworks, or the Internet, allow for the remote supplying of IT resources to the people and are directly helpful in network access in far and wide. Cloud consumers can access the cloud using only private and dedicated network links in LANs, although most clouds are Internet-enabled. The Cloud platforms generally grows in parallel with improvement in Internet connectivity and service quality, which leads to its potentiality.
Question 1c) DSL modem (Digital Subscriber Line) is a device that connects to a computer and/or a router. There are a few type of modems, they are a regular modem, cable modem or DSL modem. Why DSL modem? DSL modem is a high speed connection that requires the same exact wires as a regular telephone line. Just imagine how fast that is.
Topic 3: SOHO Broadband Level 1: Definition Question: Describe popular broadband solutions available to consumers in today’s market. Topic 3: SOHO Broadband Level 1: Definition Answer: Brief definition of broadband technologies, such as ADSL, Cable Modem, and Satellite feed. A comparison and contrast of these technologies will be a plus. Topic 4: TCP/IP Level 3:
Income inequality is the unspoken truth of American life. Millions of Americans live in poverty while the minority holds the majority of the wealth. This problem has become more severe in recent years, with the wealth gap increasing exponentially. While innovation drives economics in the free market, recent innovations have caused the wealth gap to become skewed. Broadband Internet is one particular innovation that has spurred economic growth but has hurt the lower class. Broadband Internet can be defined as “768 Kbps download and 200 Kbps upload” (Dunbar). Although there are many varying classification of broadband Internet, this definition will be utilized for the purposes of this paper. The non-adoption of broadband Internet by those living
10. A customer ordered a full T1 leased line between two sites. The telco implemented that leased line in its network using the T-carrier technology discussed in this chapter, with DS1, DS2, and DS3 lines plus switches that use time-division multiplexing (TDM) logic. Into which of the following general WAN categories does this service fit?
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 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.
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.
Internet: Global network of networks using universal standards to connect millions of different networks (Kenneth C Laudon and Jane P Laudon., 2010).
Topology: The current network was able to mix different speeds to match departmental needs. The physical topology in use is linear bus topology which also translates to a logical bus topology. The cable in use being Thicknet gives extended length allowance which is 500meters for a given segment and 2500 meters total cable
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.
