1.INTRODUCTION TO INTERENET AND ITS SERVICES

Internet : It is a network of tens of thousands of computer networks. Every network and every network on these networks exchange

Information accounting to certain rules called protocols. Two protocols used for working with the Internet are Internet Protocol or IP and

Transmission control protocol or TCP, generally known as TCP/IP. It enables the computer to talk the net’s language. It needs to known

your IP address and the address of the server to convert domain names into IP address and connects you. All your net softwares such as

newsreaders, web browsers and mail clients rely on to converse.

2. PROTOCOLS OF INTERNET

  1. Internet Protocol (IP): The most important protocol on which the internet is based. It defines how packets of data get from source to

    destination. The path of each packet is determined in a dynamic manner. IP helps to find how a packet received at an intermediate nods will

    be transmitted so that it reaches the correct destination.

  1. Transmission Control Protocol (TCP): The internet is based on the principle of packet switching for data transmission. At TCP level bytes

    are organized into packet. At the destination, the packets are reorganized into files as they existed in the source computer. Each packet is stamped

    with the IP addresses of the source and destination computer.

  1. File Transfer Protocol (FTP) : It is used to move files from one computer to another irrespective of the geographical location. It works in

    collaboration with IP to guarantee that data is correctly transmitted by the source computer and received by the destination computer.

  1. Hyper Text Transfer Protocol (HTTP) : It is a protocol to transfer hypertext pages across the world wide web.
  2. Point to Point Protocol (PPP) : All computers connected to internet have a unique address. Every time your computer is connected to the

    internet through modem, it is given a temporary IP address using PPP. It does not have permanent address. However computers permanently

    connected to the internet have permanent IP address.

    3. ADDRESSING IN INTERNET

  1. IP Addresses : Every computer connected to the internet has an unique IP address (written in dotted numerical notation) which corresponds

    to its domain name. Domain name services convert one to the other for e.g 149.174.211.5. Since it is easier to remember a name than a number,

    the internet uses Domain Name System (DNS) parallet to the IP number system. The Domain Name Services locate the numerical IP address

    corresponding to the host name.

    1. Domain : Part of the DNS that specifies details about the host, such as its location and whether it is part of a commercial, government or educational

    entity. For e.g. all internet email addresses are in the formet user@host .The host portion breaks down further into

      a) Subdomain

b) Domain type

c) Country code

e.g. Shesldh@satyam.net.in

here → shesldh is the user name

satyam is the subdomain (ISP)

net is the domain type

in is the country code

List of Domain Types

a) com : Company or commercial organization

b) edu : Educational Institution

c) gov : Government body

d) mil : Military site

e) net : Internet Gateway or ISP

f) org : Non-Profit organization

Country Codes : Every country has its own distinet code although its not always used. If address doesn’t specify a code, it is more than likely, but not

necessarily, in the USA.

a) au : Australia

b) in : India

c) uk : United Kingdom

d) us : United States of America

e) ca : Canada

f) fr : France

The DNS address of computers in the internet have following from :

Type : // address

Where type is the type of the server

Address is the address of the server.

For example

http : // www.discovery.com

here → http defines the type of the server and the protocol it follows.

→ www.discovery.com is the address of the server (web server) or domain name

4. TERMS RELATED TO WWW :

  1. Web Service: It is a place where information resides in pages. It is a programme that respond requests from web browsers to retrieve information.
  2. Web Sites : A web site is simply a collection of information in the form of files that is des to be accessed in a special way.

Why do we crave bookshops when life falls apart? A deep reading of Welcome to the Hyunam-dong Bookshop

This article reflects on Welcome to the Hyunam-dong Bookshop by Hwang Bo-reum, a gentle novel about burnout, healing, and second chances. Through Yeong-ju and her quiet community, the book reminds you that meaning often returns slowly, through books, people, and ordinary days that begin to feel like home again. Why do so many of us secretly dream of walking away from everything? At some point, usually on a crowded weekday morning or during yet another meeting that could have been an email, you wonder if this is all there is. You did what you were told. You studied, worked hard, built a career, stayed responsible. And yet, instead of contentment, there is exhaustion. Welcome to the Hyunam-dong Bookshop begins exactly at this uncomfortable truth. Hwang Bo-reum’s novel does not shout its intentions. It does not promise transformation through grand revelations. Instead, it sits beside you quietly and asks a gentler question. What if the problem is not that you failed, but that you nev...

What if You Could undo every regret? An uncomfortable conversation with The Midnight Library

Have you ever replayed your life at night, wondering how things might have turned out differently? The Midnight Library by Matt Haig asks you to sit with that question. Through Nora Seed’s quiet despair and imagined alternatives, the novel explores regret, possibility, depression, and the fragile hope that living at all might be enough. Have you ever wondered if one different choice could have changed everything? You probably have. Most people do. Usually at night. Usually when the world goes quiet and your mind decides to reopen old files you never asked it to keep. The job you did not take. The person you loved too late or too briefly. The version of yourself that felt possible once. You tell yourself that if you had chosen differently, life would feel fuller, cleaner, less heavy. The Midnight Library begins exactly there, in that familiar ache. Not with drama, but with exhaustion. Not with chaos, but with a woman who feels she has quietly failed at everything that mattered. Mat...

Debate : Do the ends justify the means...

Note : Give it all a fair thought before you jot down... Flaming and religion-bashing will not be tolerated. Your participation is gladly appreciated. I dunno if you folks remember this incident; a couple of yrs back, the UPSC exam had a question where the emainee had to assert his views on *revolutionary terrorism* initiated by Bhagat Singh. As is typical of the government, hue and cry was not far behind... Anyway, let us look at some facts -   Bhagat Singh was an atheist, considered to be one of the earliest Marxist in India and in line with hi thinking, he renamed the Hindustan Republican Party and called it the Hindustan Socialist Revolutionary Party. Bhagat Finally, awaiting his own execution for the murder of Saunders, Bhagat Singh at the young age of 24 studied Marxism thoroughly and wrote a profound pamphlet “Why I am an Atheist.” which is an ideological statement in itself. The circumstances of his death and execution are worth recounting. Although, Bhagat Singh had a...
