The Beginner’s Guide to Internet
When you hear the term “internet”, what is the first thing you think of? Internet is also known as “the Net”. It is a worldwide system of computer networks in which users at any one computer can get data from any other computer. It was conceived by the ARPA or also known as Advanced Research Projects Agency of the United States government in 1969 and was first known as the ARPANET. The ultimate aim was to create a network that would allow users of a computer at one university to be able to communicate with computers at other universities.
- One of the benefits of ARPANET’s design was that, messages could be sent in more than one direction. In this way, the network could continue to function even if parts of it were destroyed in the event of a military attack or other disaster. In the recent year, the internet is self-sustaining and it is utilized by millions of people in different parts of the world.
- For many internet users, email has replaced the Post Office for short messages. In addition to this, you can also carry on live conversations with other computer users using internet chart. Recently, internet telephone software and hardware allow real-time voice conversations including free long distance for voice calls between two computers.
World Wide Web
- The most widely used part of the internet is the World Wide Web. On most websites, certain phrases and words appear in text of a different color than the rest and sometimes also underlined. When you point to one of these phrases or words by clicking the left button of your mouse, you will be transferred to the page that is associated with this phrase or word.
- These are called links or hyperlinks. Sometimes there are portions of images, buttons and images that can be clicked. Once you move the pointer over a spot on a website and the pointer changes into a hand, this indicates that you can click it and be transferred to another site.
- With the help and existence of web, you have access to millions of pages of information. Web browsing is done with a web browser. Today, the most popular web browsers are Mozilla Firefox and Microsoft Internet Explorer. Depending on your connection speed, browsers can support advanced features such as music, sound, video and animation.
- Aside from this, the browsers that are stated above can be downloaded absolutely free. The World Wide Web and Internet, in combination, are a worldwide free-broadcast medium for the general public. Using your GPS, movie player, Xbox, smartphone, Mac and PC, you can access a vast world of messaging and useful content through the Net.
The Net has subnetworks. The biggest subnetwork is the World Wide Web, comprised of HTML hyperlinks and pages. Other subnetworks are FTP downloading, P2P, instant messaging and email. You can connect to the Internet with the use of private internet service provider, a public Wi-Fi network or through your office’s network. The expressions internet and web are used interchangeable by the layperson. This is technically incorrect, as the Web is contained by the Internet.
