Internet and World Wide Web is second last topic of
information technology (IT). In our tutorial lab class our beloved lecturer
explained about that topic. Before she started lecture, she asked students
whether they had some knowledge about internet and worldwide web or not .Some
students tried to explain their knowledge about internet and www. After getting our point of view, she started
to explain that topic more clearly. First of all, she explained about internet.
Internet is largest network in the world that connects people all over the
world and it has been using in different fields all over the world from last
few decades. To build over knowledge about the use of internet around the world
we came to know some of the applications of the internet such as, access
information, Send (upload) or receive (down load) files between computers and
share resources.
Then she explained about history of internet. As I was
well aware about its history, so it became clearer to me. The history of
internet is shown in the following diagram:
The most interesting thing is that internet is
providing various kinds of facilities to its users such as, E-mail, chat room,
protocol, IR and instant message. She explained each facility very well. I was
able to get the concept of the web server and web client.
I was quite able to differentiate between web server
and web client. Every Web server has an IP address and possibly a domain name
and Web client end user PC. She provided knowledge about transfer protocol that
is the set of rules/software that computers use to move files from one computer
to another by using internet. At last she taught about chat rooms VoIP and news
group. According to my awareness, chat rooms are channel/medium/location on
Internet that allow people to chat with each other while VoIP(voiceover
Internet Protocol) uses internet to make people call/video call and allow
people to speak other users over internet through Skype and yahoo voice.
