__ ** Internet Infrastructure ** __

=
An Internet service provider (ISP) is a company that provides access to the Internet. For the home user, this typically occurs through a cable or digital subscriber line (DSL) modem (modulator-demodulator) that sends and receives digital data through a television cable connection or a phone line. 1 A Local Area Network (LAN) is a group of computers that are in the same general area and are usually seen in a business environment. A wide area network (WAN) may connect a LAN to other branches of the business. 3 ======

=
The Point of Presence is where the ISP exists in the physical world and allows users to access their network via telephone, cable, or dedicated line. There is no controlling network in these areas, but instead a series of networks connecting through Network Access Points (NAPs). 2 ======

=
Networks rely on NAPs to talk to one another. The NAP backbone is the cabling of a network. It is capable of carrying more information than single units. Routers are apart of this backbone. Routers are physical devices that receive or send data out as requested by the user. 2 ======

An Internet Protocol or IP address is the unique number assigned to a computer. IP is the language computers use to communicate over the Internet. The protocol is defined by the way a person wants to use that service. IP addresses are made up of octets that are actually binary numbers. It uses mathematical formulas that only equal up to a sum that contains zeros and ones. Net octets are used to identify the network a computer is connected to while Host or Node is the computer itself. 5

=
A Domain Name System (DNS) converts IP addresses into simplified links such as www.youtube.com instead of a long number system that computers use. The domain name is also used in Uniform Resource Locators (URL). URL is a link to a specific location in the networks. 6 ======

Servers are computers that provide services to other computers, where as clients are the computers requesting the data. Servers can be accessed through ports with each one having their own protocol. One protocol is the Hypertext Transfer Protocol (HTTP) which is the way a computer reads the data given to it and translates it back to you. 4

** __Personal Impacts:__ **
With the invention of Internet Infrastructure many people have gone into the field of computer science. This structure allows one to communicate and learn from others. Many have become more aware of things going on in the world due to such a complex system being created and allows one to research topics a person may have otherwise never known.Such examples of this is the fact the news can now be found on the internet.

** __Political and Global Impacts:__ **
The invention of Internet Infrastructure has created jobs in the computer field, thus improving society when it comes to business and entertainment. With the internet working on such a complex system, there is no shortage of data to be sifted through. The global impact of the internet allows people in general to communicate easier with one another across vast distances. Thus, markets have improved because marketers can keep in contact with their providers and consumers.

Politically speaking,<range type="comment" id="683401"> the creation of Internet <range type="comment" id="578618">infrastructure has allowed for politicians to spread <range type="comment" id="461720">their views and ways over greater distances. This makes it easier to follow politics, and allows for a new form of political advertisement. Most political meetings can be re-watched thanks to the infrastructure of the <range type="comment" id="14734">Internet.
