III. Short Answer Type Questions
Question 1.
Why internet is called network of networks?
Answer:
The internet is a global network of computers. It is called a network of networks because rather than having one layer where all computers are connected together on the same level, computers are grouped together on separate networks or LANs (Local Area Network). These networks are small groups of computers which can all talk to each other. When any of these grouped computers needs to communicate with a computer outside of their group or “network”, they will send information through what is called a “gateway” which will rout traffic across the internet to either another network or to a specific computer on the internet.
Question 2.
What is internet protocol?
Answer:
The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.
Question 3.
Define World Wide Web.
Answer:
It is important to know that this is not a synonym for the Internet. The World Wide Web, or just “the Web,” as ordinary people call it, is a subset of the Internet. The Web consists of pages that can be accessed using a Web browser. The Internet is the actual network of networks where all the information resides. Things like Telnet, FTP, Internet gaming, Internet Relay Chat (IRC), and e-mail are all part of the Internet, but are not part of the. World Wide Web. The Hyper-Text Transfer Protocol (HTTP) is the method which is used to transfer Web pages to your computer. With hypertext, a word or phrase can contain a link to another Web site. All Web pages are written in the hyper-text markup language (HTML), which works in conjunction with HTTP.
Question 4.
What is HTTP?
Answer:
The Hypertext Transfer Protocol {HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text.
Question 5.
What is the significance of web-browser?
Answer:
A web browser (commonly referred to as a browser) is a software application for retrieving, presenting, information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content.
Question 6.
What is HTML used for?
Answer:
HTML, or Hypertext Markup Language, is used to create web pages. Site authors use HTML to format text as titles and headings, to arrange graphics on a webpage, to link to different pages within a website, and to link to different websites. HTML is used to Create a Web Document. HTML is used to Navigate the Internet.
Question 7.

IV. Long Answer Type Questions
Question 1.
What is the World Wide Web? Also write its characteristics.
Answer:
World-Wide Web (also called WWW or W3) is a hypertext-based information system. Any word in a hypertext document can be specified as a pointer to a different hypertext document where more information pertaining to that word can be found. The reader can open the second document by selecting the word, only the part of the linked document which contains relevant information will be displayed.
The second document may itself contain links to further documents. The reader need not know where the referenced documents are, because they will be obtained and presented as they are needed. World-Wide Web uses hypertext over the Internet: the linked documents may be located at different Internet sites. WWW can handle different text formats and different methods of organizing information.
The World-Wide Web also provides access to many of the other tools described in this guide, and is becoming widely used as the major means of access to Internet resources. The World Wide Web has inherent properties that characterize its expressive possibilities:
- Unbound in space/time: Information provided on the Internet is available every day, around the clock, and around the world (pending network operation).
- Bound in use context: Web-based hypertext fosters associations works through links, giving rise to networks of meaning and association among many information sources that may be scattered across the globe and written by many authors.
- Distributed, non-hierarchical: The Web’s technical organization as an application using the Internet for a client/server model influences the disintegration of user focus on a single outlet for experiencing content.
Question 2.
What is web browser? Also write its work.
Answer:
A web browser (commonly referred to as a browser) is a software application for retrieving, presenting, information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content[1] Hyperlinks present in resources enable users to navigate their browsers to related resources.
Although, browsers are primarily intended to use the World Wide Web, they can also be used to access information provided by web servers in private networks or files in file systems.
The major web browsers are Firefox, Internet Explorer/Microsoft Edge, Google Chrome, Opera, and Safari.
The primary purpose of a web browser is to bring information resources to the user (“retrieval” or “fetching”), allowing them to view the information (“display”, “rendering”), and then access the other information (“navigation”, “following links”).
This process begins when the user inputs a Uniform Resource Locator (URL), for example http://en.wikipedia.org/, into the browser. The prefix of the URL, the Uniform Resource Identifier or URI, determines how the URL will be interpreted. The most commonly used kind of URI starts with http: and identifies a resource to be retrieved over the Hypertext Transfer Protocol (HTTP).[17] Many browsers also support a variety of other prefixes, such as https: for HTTPS, ftp: for the File Transfer Protocol, and file: for local files. Prefixes that the web browser cannot directly handle are often handed off to another application entirely. For example, mailto: URIs are usually passed to the user’s default e-mail application, and news: URIs are passed to the user’s default newsgroup reader.
Question 3.
What is HTML? How it is useful to develop a web page?
Answer:
HTML (Hypertext Markup Language) is the set of markup symbols or codes inserted in a file intended for display on a World Wide Web browser page. The markup tells the Web browser how to display a Web page’s words and images for the user. Each individual markup code is referred to as an element.
Creating web page using HTML:
- Understand what HTML is.
- Make your initial web page as simple as possible.
- Go to Start, then “Programs” and then “Accessories.”
- Tell the browser what language you are using.
- Add the heading of the page as shown.
- Give your page a title.
- Work on the body of the page.
- Write some text between the body tags.
The HTML editors provide a built-in browser window, which allows you to preview your work. Also, you might want an HTML editor that has a validator. That way, the editor can help find mistakes. It’s kind of like using spell checker in a word processor. However, just like spell check does not catch all mistakes, neither will a validator. Your best chance of success is to develop the eye-of-a-hawk and catch your own typos and mistakes. Writers and editors pay close attention to detail and this skill is equally important to web developers. If you miss even one closing tag, your entire page could be affected. Don’t let this scare you. As long as you pay attention to what you’re doing, you’ll be fine. The best rule of thumb is to type slowly, check your work as you go, and constantly test.
Question 4.
What is utility of Domain Name and Domain Name Server in Internet?
Answer:
A domain name is actually a lingual representation of an IP address, which is a series of numbers separated by dots. Every web site is given an IP address, however it is more difficult to remember this segmented sequence of numbers instead of remembering a simple phrase. This is the basic concept of domain names, but the process through which an IP address is translated into a domain names is a bit more complicated.
Domain Name Server, A DNS (Domain Name System) server is a type of web server which is used to interact with the domain name system, which is the global directory of domain names and corresponding IP addresses. DNS technology automatically translates long and confusing IP address (which are segmented number sequences separated by dots, such as 127.0.0.1) into standard domain name that is easier to remember.
The domain name system is comprised of thousands of domain name servers around the world, which accumulatively make up the largest digital database on the planet. DNS servers operate using special software that transmits data from the DNS server to various web hosts upon request.
Question 5.
Write short note on each of them:
(i) Search Engine
(ii) e-mail
(iii) URL
(iv) IP Address
(v) Web Protocol
Answer:
(i) Search Engine: A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a mix of web pages, images, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.
(ii) e-mail: E-mail (electronic mail) is the exchange of computer-stored messages by telecommunication. (Some publications spell it email; we prefer more established spelling of e-mail.) E-mail messages are usually encoded in ASCII text. However, you can also send non-text files, such as graphic images and sound files, as attachments. E-mail was one of the first uses of the Internet and is still the most popular use. A large percentage of the total traffic over the Internet is e-mail. E-mail can also be exchanged between online service provider users and in networks other than the Internet, both public and private.
(iii) URL: URL is the abbreviation of Uniform Resource Locator. URL is the global address of documents and other resources on the World Wide Web. Parts of a URL: The first part of the URL is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. The protocol identifier and the resource name are separated by a colon and two forward slashes.
For example, webopedia.com. The first specifies an executable file that should be fetched using the FTP protocol; the second specifies a Web page that should be fetched using the HTTP protocol.
(iv) IP Address: An IP address is a fascinating product of modern computer technology designed to allow one computer (or other digital device) to communicate with another via the Internet. IP addresses provide the location of billions of digital devices that are connected to the Internet to be pinpointed and differentiated from other devices. In the same sense that someone needs your mailing address to send you a letter, a remote computer needs your IP address to communicate with your computer. An IP address consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number or set of digits. Each of the four numbers can range from 0 to 255. Here’s an example of what an IP address might look like: 78.125.0.209.
(v) Web Protocol: The Internet relies on a number of protocols in order to function properly. A protocol is simply a standard for enabling the connection, communication, and data transfer between two places on a network. Here are some of the key protocols that are used for transferring data across the Internet.
HTTP, HTTPS, FTP etc.
HTTP stands for Hypertext Transfer Protocol. It is the standard protocol for transferring web pages (and their content) across the Internet.
