1. Impact of the Internet in our world today.

     The introduction of Internet to the world changed the nature of work and lifestyle in various ways. It allowed us to utilize the advancement of technology to cut the barriers of long distance communication, thus internet became a tool in the fast phase of globalization. Its impact elevated the aspect of our lifestyle which made us more sophisticated and at the same time costly.

     There are several disadvantages and advantages with the availability of Internet. If we try to look at its perils, Internet became avenue for abhorrent actitivities. For instance, pornography is rife in its database where in children gets an easy access to it, therefore intoxicating the minds of the children through the engagement of pre-marital sex and resulting to early pregnancy. Moreover, Internet is also used as a tool by unscrupulous people to easily lure their victims for the purpose of making money. On the other hand, many people still use internet for the best reasons particularly retrieving educational information for the use of their study. Furthermore, socialism is made easy because of the world wide web accessed by the internet, giving everyone the opportunity to socialize even at the bounce of their homes in the raise of humanity.

2. Give a brief desription of the following Internet organizations:
  • IAB (Internet Architecture Board) - is an independent committee of researches and professionals with a technical interest in the health and evolution of the Internet System. (1979)
  • IETF (Internet Engineering Task Force) - a group of loosely organized volunteers who discuss, develop, and publicize Internet standards. (1986)
  • ISOC (Internet Society) - is an international, nonprofit organization to provide direction in Internet related standards, education, and policy. (1992)
  • InterNIC (Internet Network Information Center) - an umbrella entity created by the National Science Foundation in cooperation with the Internet community, consisting of Network Information Service Managers who provided and/or coordinated NSFNet services.(1992)
  • IESG (Internet Engineering Steering Group) - a body composed of the Internet Engineering Task Force Area Directors and the IETF Chair. It provides the first technical review of Internet standards and is responsible for day-to-day "management" of the IETF. (1994)
  • IANA (Internet Assigned Numbers Authority) - the body responsible for coordinating some of the key elements that keep the Internet running  smoothly. (1994)
  • IRTF (Internet Research Task Force) - promotes research of importance to the evolution of the Internet by creating focused, long-term research groups working on topics related to Internet protocols, applications, architecture and technology. (1996)
  • ICANN (Internet Corporation for Assigned Names and Numbers) - manages the domain name system and allocation of IP addresses. (1998)
3. After watching the video on how the Internet works, answer the following questions:

  • What made the internet reliable and efficient?
    • It is reliable because Internet is where you can find almost everything you need to know and do almost everything you want, chat, send important files, even shop online. It makes communication with people faster. It's efficient because anyone can use it. You just need to have a computer and a network. And you can do Internet the whole day. 24/7. :  
  • What principles applied in the Internet that could also be beneficial in other areas?
    • Agreement. Like what is said it the video, it's like a game, you agree to play by the rules. Same as in the internet. If you will follow the rules, how it's used then everyone can benefit from it. Anyone around the world. You can connect it to different server as long as you and the other party agree and stick to the rules implemented.
4. In your own words, explain the TCP/IP Protocol Suite (Internet Model). Minimum of 250 words, 500 maximum.
      
        TCP/IP is basically a file transfer. It is a reliable way of delivering your data and is still used until now by everyone who has Internet. It is also independent, it is not just with one company, any company is free to use it. It has four layers, Application Layer, Transport Layer, Internet Layer and Network Access Layer. These layers are the steps of how data is transferred, composed of data and headers. To know its latest version, you can search for RFC also known as Request For Comments.
