- WEB DESIGNING TEST
- Define WWW. Write the history of WWW?
WWW stands for World Wide Web, which is also known as a Web .It is a collection
of websites or web pages stored in web servers and connected to local computers through the
internet. These websites contain text pages, digital images, audios, videos, etc. Users can
access the content of these sites from any part of the world over the internet using their
devices such as computers, laptops etc. The WWW along with internet enables the retrieval
and display of text and media to your device.
HISTORY: The World Wide Web was invented by a British scientist, Tim Berners-Lee in
- He was working at CERN at that time. Originally, it was developed by him to full fill
the need of automated information sharing between scientists across the world, so that they
could easily share the data and results of their experiments and studies with each other.
Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN
WWW – World Wide Web
The basic idea of the WWW was to merge the evolving technologies of computers, data networks and hypertext into a powerful and easy to use global information system.
2. Write a note on:-
- INTERNET DOMAINS
- INTERNET PROTOCOL
HTTP:- Hypertext Transfer Protocol
HTTP stands for HyperText Transfer Protocol. It is a protocol used to
access the data on the World Wide Web. The HTTP protocol can be used to transfer
the data in the form of plain text, hypertext, audio, video, and so on. This protocol is
known as HyperText Transfer Protocol because of its efficiency that allows us to use
it in a hypertext environment where there are jumps from one document to another
document. HTTP is similar to FTP. FTP stands for file transfer protocol as it also
transfers the files from one host to another host. But HTTP is simpler than FTP as
HTTP uses only one connection that is no control connection to transfer the files.
A domain name is a unique name that identifies. Each
website has a domain name that serves as an address, which is used to access the
website For example the domain name of the Sourav Computer Dictionary is
sourav.com. Whenever you visit a website, the domain name appears in the address
bar of the web browser. Some domain names are preceded by www which is not part
of the domain name while others omit the www prefix. All domain names have
a domain suffix, such as .com, .net, or .org.
INTERNET PROTOCOL – IP
IP stands for Internet Protocol. It is a protocol defined in the TCP/IP model used
for sending the packets from source to destination. The main task of IP is to deliver
the packets from source to the destination based on the IP addresses available in the
packet headers. IP defines the packet structure that hides the data which is to be
delivered as well as the addressing method that labels the datagram with a source and

hypermedia information systems. This is the foundation for data communication for the World Wide Web (i.e. internet) since 1990.
Basically, HTTP is a TCP/IP based communication protocol, that is used to deliver data (HTML files, image files, query results.
HTTP is a TCP/IP based communication protocol

types of domain:- .com, .in, .xyz, .org, .net, .info etc.
- INTERNET PROTOCOL – IP
The Internet Protocol (IP) is a protocol for routing and addressing packets of data so that they can travel across networks and arrive at the correct destination.
and this information helps routers to send packets to the right place.
3. Difference between HTTP & HTTPS
|Hypertext transfer protocol||Hypertext transfer protocol secure|
|It is a protocol used by the World|
Wide Web and this protocol defines
how messages are formatted and
transmitted, and what actions Web
servers and browsers should take in
response to various commands.
|HTTPS is the use of Secure Socket Layer|
(SSL) or Transport Layer Security (TLS)
as a sublayer under regular HTTP
application layering. HTTPS encrypts and
decrypts user page requests as well as the
pages that are returned by the Web server.
|Attacker Can Try man in the middle.||It is secure against attacks.|
|It is Unsecured.||It is secured.|
|It doesn’t require domain validation.||It requires domain validation.|
4. What do you mean by HTML? Write 10 BASIC TAGS WHICH WE CAN USE TO CREATE A WEBPAGE.
TEXT FORMATTING : HTML Formatting is a process of formatting text for better look and feel. HTML provides us ability to format text without using CSS. There are many formatting tags in HTML. These tags are used to make text bold, italicized, or underlined. Some of them are discussed below :
- <html> … </html> — The root element
- <head> … </head> — The document head
- <title> … </title> — The page title
- <body> … </body> — The page’s content
- <h1> … </h1> — A section heading
