Question

In 500 words or less describe with your own words the steps included in a Web session.

You can use an example describing the internal steps in the system from the moment a person wishes to visit a website to the moment the website information is displayed on the computer screen for the user.

You may use a point-form numbered list to describe each step of the process.

Make sure to describe concepts such as:

Web Browser, URL, Doman name, IP Address, Web Server, TCP, HTTP, and HTML.

Answer 1

first let us understand the concepts related to a web session:

1. Web Browser: Web Browser is nothing but a software application that helps the user device in viewing and accessing the resources available on the world wide web or say internet. All the web pages , images or videos can be viewed on a web browser that are available on a web server.

2. URL : URL stands for Uniform Resource Locator. Every web page or image or video available on the web is assigned a unique URL.URL is generally a web address that tells about the resources available on the web and how to retrieve them.

3. Domain name: Domain name is defines as the name of a website. It the name which is used by the users to access a website on the web. Domain name are generally used to identify the computers and the websites. They have the extension like .com or .in etc.

4. IP Address: IP Address may be defined as a unique id assigned to each and every electronic device connected to the internet. Every mobile phone or computer in the world has a unique IP Address.

5.Web Server: A web server is a software or hardware that may contain several databases and multiple websites. Web servers are generally used to satisfy the web requests for pages, images or videos made by the client.

6. TCP: TCP stands for Transmission Control Protocol.TCP is a internet protocol that is generally used for the transmission or exchange of data . TCP is a protocol that establishes the connection between the sender and the receiver and provides guaranteed transmission of data.

7. HTTP : HTTP stands for HYPER TEXT TRANSFER PROTOCOL. This is also a internet protocol which supports the request response model. The client makes a HTTP request and the web server provides the response. It is the foundation of data transfer on the internet.

8.HTML : HTML stands for HYPER TEXT MARKUP LANGUAGE . HTML is a programming language that is generally used to develop the website or web pages.

Now lets talk about the web session:

A typically web session is generally a HTTP session that follows the client server architecture.It has the following steps :

1. The client that is generally a web browser establishes a TCP connection for the exchange of data . Here the client establishes the connection with the underlying transport layer.

2. The client then sends the HTTP request  and then waits for the response. This HTTP request contains the document that is needed, the path to it and the HTTP header which contains information about what type of data is required.

3. After the client has sent its request to the web server, the web server processes it and sends the response to it.This response consists the acknowledgement of the request received, the type of data sent through the response. It also contains the status whether the request has been successfully completed.

4. Finally the requested web page is displayed on the web browser.
