TCP/IP (Transmission Control Protocol/Internet Protocol) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet).
The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment.
File transfer protocol
• FTP (File Transfer Protocol) is the simplest and most secure way to exchange files over the Internet.
• Transferring files from a client computer to a server computer is called uploading and transferring from a server to a client is downloading.
• To access an FTP server, users must be able to connect to the Internet or an intranet (via a modem or local area network) with an FTP client program.
Slide Contains:
1. Introduction
2. Objectives of FTP
3. Mechanism of FTP
4. types of connections in FTP
5. FTP Clients
6. Advantages of FTP
7. Disadvantages of FTP

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

3. What is
HTTP?
HTTP (Hypertext Transfer Protocol) is the set of rules for
transferring files (text, graphic images, sound, video, and
other multimedia files) on the World Wide Web.
Communication between client computers and web servers
is done by sending HTTP Requests and receiving HTTP
Response.
HTTP is an application layer protocol
Connectionless protocol
stateless
5. HTTP session
consist of
three phases:
The client establishes a TCP connection
The client sends its request and then
waits for the answer
The server processes the request and
sends back its answer, containing a status
code and the appropriate data.
The connection is closed.
6. Methods
HTTP SUPPORTS SEVERAL DIFFERENT REQUEST
COMMANDS, CALLED HTTP METHODS. EVERY
HTTP REQUEST MESSAGE HAS A METHOD.
THE METHOD TELLS THE SERVER WHAT ACTION
TO PERFORM.
7.
8. HTTP Request / Response
Communication between clients and servers is done by requests and responses:
1. A client ( a browser) sends an HTTP request to the web
2. An web server receives the request
3. The server runs an application to process the request
4. The server returns an HTTP response (output) to the browser
5. The client (the browser) receives the response
9. The HTTP
Request
Circle
A typical HTTP request/ response circle:
The browser requests an HTML page.
The server returns an HTML file.
The browser requests a style sheet. The
server returns a CSS file.
The browser requests an JPG image.
The server returns a JPG file.
12. START LINES
All HTTP messages begin with a start line. The start line for a request message
says’what to do’. The start line for a response message says what happened.
13. Headers
HTTP message headers are used to
precisely describe the resource being
fetched or the behaviour of the server or
the client. There are four types of HTTP
message headers:
1. General headers
19. What is World Wide Web ?
o The World Wide Web is a way of exchanging
information between computers on the
Internet.
o The World Wide Web is the network of pages of
images, texts and sounds on the Internet which
can be viewed using browser software .
20. The World Wide Web
o The World Wide Web, or Web, consists of a worldwide
collection of electronic documents (Web pages)
o A Web site is a collection of related Web pages and
associated items
o A Web server is a computer that delivers requested Web
pages to your computer
o Web 2.0 refers to Web sites that provide a means for
users to interact
21. History
(www) was Invented between 1989 – 1990,
by Tim Berners Lee at Cern .
Published in 1992 - Means for transferring
text and graphics
Using Text mark up
language (HTML)
•- invented by Bernes-Lee
•- Simple and easy to use
23. -The Fundamental Concept of World Wide Web-
Hypertext is text which contains links to
other texts.
Hypermedia is a term used for hypertext
which is not constrained to be text: it can
include graphics, video and sound
1. The Hypertext concept 2. The Hypermedia concept
24.
25. o Web Browser:
A web browser displays a web document and enables users to access web
documents.
o Web Server:
This is a program that waits patiently for the browser to request a web page. The
servers looks for the requested information, retrieves it and send it to the browser
or sends an error message if the file is not found
o URL (Uniform Resource Locator):
These are the web addresses. The resource locator is an addressing system .
28. Many people use the terms Internet and World Wide Web,
but in fact they’re are not the same.
• The Internet and the Web are two separate but related things.
• The Internet is a massive network of networks. It connects
millions of computers together globally.
• The Web, is a way of accessing information over the medium of the
Internet.
*So the Web is just a part of the Internet, actually a large Part, but the
two terms are not synonymous and should not be confused.*
29. Summary
• WWW is a way of exchanging information.
• Tim Berners Lee invents the World Wide Web (www) at
Cern .
• WWW is constructed using HTML.
• Internet and WWW are the two different concept.
30. Differences between HTTP and WWW:
1. HTTP is the protocol used to transfer data to and from the website.
2. WWW is the identifier that indicates that it is a web site and it uses the HTTP protocol.
3. HTTP://anything.com, WWW.anything.com, HTTP://WWW.anything.com leads to the same
site.
4. Any prefix that is not reserved to a protocol can be used as a sub domain.
