The document discusses how the internet, domain names, and the world wide web work. It explains that web pages are stored on web servers connected to the internet. These servers are identified by unique IP addresses but are easier for humans to access using domain names. The Domain Name System (DNS) converts domain names into the corresponding IP addresses so browsers can locate the correct server. Traffic to a website comes from people directly typing the URL, links from search engines, referrals from other sites, and other online marketing activities.
Internet, domain name, worldwideweb
- 2. HTML & HYPERLINKS To surf internet, one types an address (URL) in the browser. The browser locates and displays the page on the PC The page will have text, images, videos etc. Each of these element perhaps is further linked to another page. (these links or text are called as hyperlink or hypertext) Hyperlinks- text pointing to other pages. Clicking on these links take you to a different page or a different location in the same page HTML- Hyper text mark up language. A language in which pages on the internet can be written and displayed in a browser. Html invented by Tim Bernes Lee, scientist at CERN, Geneva
- 3. Web Server When you type an address in the browser Where does the page come from? How is it brought to your PC? The web-pages are stored/hosted on servers that are connected to internet or web. These servers are called Web-servers. Since you request several pages which may be hosted in different parts of the world on different servers- all the web- servers hence are also interlinked like a spider’s web. Thus the name world wide web.
- 5. IP Millions of web servers. How does one know which server to connect to for a webpage? All computers have a unique address (just like our portal addresses) This address is a number like: 110.22.206.18 4 numbers. Separated by ‘.’ Between 0 and 255 This addressing scheme is known as IP Addressing scheme or Internet protocol address (IP Address)
- 6. More on IP Every computer on internet has an IP address. This is how web servers locate the computers in order to serve the desired page. These computers are called ‘hosts’ We currently use IP Version 4 (IPV4) which can allocate 4 billion IP addresses. We are moving towards IPV6 which can allocate two hundred million million million million million million addresses!
- 7. The DNS Domain Name System It’s difficult to remember the IP addresses for each website, hence the need for domain names. For example: travel.atomthought.com refers to a server called ‘travel’ which is located on a domain ‘.atomthought’ which in turn is located in a domain ‘.com’ Analogy- saurabh.sector-49.faridabad.india tells you the complete address of a particular ‘saurabh’ This method of naming servers is called the DNS- Domain name system
- 8. DNS Resolution If you type a domain name in your browser The browser tries to locate the domain name in the closest domain name server. If not found the request is sent to other domain name server in the next level domain This process of finding the IP address for a given domain name is called Domian Name Resolution
- 9. Top Level Domains Largest domains (the rightmost in a URL) in any domain name are standardized There are two types of Top Level domains COUNTRY (.in, .cn, .uk etc.) CATEGORY (.com, .org. .edu etc.)

- 11. Traffic The number of visitors on your website We count them as Unique Visitors One visitor can come more than once (visits) Page-View- When any page is fully loaded in the browser Relevant Traffic Visits that are single page only are also called as bounced. This is bad traffic. If you target visitors well (age group, location, intent, content preference etc.) you will get relevant traffic.
- 12. Traffic Sources Direct Directly types URL in a browser Search Search engines (Paid and Unpaid) Referral E-mailers, blogs, social networks, news sites etc. Website Direct ReferralSearch
- 13. How do you get traffic Get Traffic Social Media Marketing Search Engine Marketing eMail Marketing Targeted Display Advertising Alliance & Partnership Your own website Mobile Marketing/Apps

- #3: What is a website?How do u visit a website?U use a web brower. Type the URL in the address baar and visit a website.A website is a collection of webpages. Webpages r made of hypertext markup language.Its got links to other pages through text links and images. These links r called hyperlinks,.. Geeks never keep a easy name for anything. This emans that various websites r connected to each other. Websites r hosted on computers called web servers. This means webservers r connected to each other in a spider mesh. So called WWW.Now like evry house has a unqiueadress for posts to each it. Similary websites have IP adresses. Xxx.yyy.jjj.hhhUnique adress. Now the problem is its not easy to remebr IP adresses.. But names. Which one is easy to rember if u had to access yahoo mail.. Visitng mail.yahoo.com or 124.66.75.311?But each computer needs IP adress. So to resolved the same..DNSWhen urbrower goes to yahoo.com.. It goes to DNS server to ask its IP.. And then connectes to it.
