Media Analysis Project: How the Internet Functions

            The Internet and other forms of communication media have various technologies and infrastructures that permit correct functioning and operation.  Among these are the Internet Service Provider or ISP, digital subscriber line or DSL, the transmission control protocol/Internet protocol or TCP/IP, the IP routers, the domain name system, the protocol software, the URL, the file transfer protocol (FTP) servers, plus the administrations that control the execution of the Internet.  All these make way for the Internet to perform well.

Main Body

            There are a number of technologies and infrastructures that allow the Internet to function well in connecting the two computers that are being connected: clients and servers.

The Internet Service Provider or ISP provides the software that controls the modem through the use of a device that would connect the computer system to a telephone system, such as the dial-up cable modem.  In the case of the dial-up, the ISP receives calls from the cable modem and the two modems use certain audible tones that send and represent data to both directions.  This data is being converted back to digital values through the ISP.

            The Transmission Control Protocol/Internet Protocol or TCP/IP provides the set of protocols important to detect and correct problems in the transmission of data.  It can detect failure to malfunction, find alternative paths for the packets, as well as ensure that the data arrives full and intact.  This protocol software ensures the correct transmission of data.

            In the MSN Encarta article entitled “Internet,” Internet Protocol Routers or IP routers are being described as “hardware devices that connect networks in the Internet” (1).  These devices follow certain IP protocols that are being forwarded while delivering the packets to their destination through the use of a local network.  It can also be forwarded to another router before being delivered to its final destination.

            The domain name system assigns a unique number to the computer, which is also known as the Internet Protocol address or IP address of the computer, which is its final destination.  There are intermediate routers that are being used here, while each computer has a domain name that makes it easier for users, as compared when the exact IP address of the computer source is used.  Protocol software translates these domain names into IP addresses.

            According to MSN Encarta, the Uniform Resource Locator or URL includes “the domain name of the computer on which the page is located” (2).  There are portions that dictate further details about the type of data that is being included in the webpage, such as html to signify that it uses the html protocol under TCP/IP; or pdf to signify that it uses the pdf protocol under the same TCP/IP.  URLs give the address of the exact webpage.

            Lastly, the File Transfer Protocol servers or FTP servers receive the data through the host server by means of web server channels that commonly use browser connection strings that are included in the browser address.  In the article entitled Domain Name System, FTP clients are being recognized as “software program designed specifically for the bi-directional transfer of files” (2007).  FTP servers function through with the help of the FTP client.


Based on the article The Internet in Practice, the Internet can be defined as “a network of computer networks interconnected by communications lines of various compositions and speeds” (2007).  This is an immense network of networks that is composed of routers that guide the connections and administer the traffic of these networks, as they go to their specific destinations.  For the Internet to function well, numerous technological systems and infrastructures are vital, as they provide a way to connect a network of networks.
