Stages of development of the Internet

Internet is an essential part of one’s life in today’s world. It is a very vast connection of networks and computers over the entire world. Internet carries a large amount of information. It connects all the computers globally through millions of networks and the World Wide Web. The Internet can be used for sending mails, watching videos or TV, reading newspapers and books. Everything has come up on the internet making all of it accessible easily. There are chat rooms, social networking sites, blogs, B2B websites and many other facilities. It also has certain protocols and norms to follow. It uses TCP/IP while serving all its users around the globe.

Before Internet

Before the existence of the Internet, all that the world had for communication of data was telegraph, radio, TV and other means of broadcasting. With the advent of the Internet the scenario completely changed.

Origin of the Internet

The Internet was originated around the year 1960 as a result of research done by the military services of the United States in order to develop error free computer systems. IT was later commercialized in 1990 as international network and famously was known as the internet.

The usage and access of internet is not defined by any organization. There exists a maintainer organization which assigns the domain name as well as the IP address which define the location of any website or page over the internet. They represent the identity of a webpage.

Different terminologies for the Internet

The Internet is technically a short form for inter network as it a huge connection of many computer networks. It is also widely referred to as ‘the net’. These connections are facilitated using URL’s and hyperlinks.

Stages of development in the Internet

Initially it was limited to governmental organizations and secret programs. There the interconnection between computers was using the principle of message blocks. With its commercialization it made a great impact on the society. At the beginning the features were the normal surfing of web pages, access to electronic mail, chat rooms and forums. Here the concept of packet switching was being made use of.

Networks leading to the Internet’s development

The first network was ARPANET. It was first developed by a Professor from MIT and its first connection was between University of California and the research unit at Stanford. This gave birth to the core of the Internet. It is still being used at a small scale for some functions. Here the networks were made to take care of reliability.

The next network was X.25.  It was based on packet switching and it made use of telephone lines. The networks that followed later were UCCP and NPL. All the above mentioned networks were merged to give birth to the Internet. Unlike ARPANET, here hosts took care of reliability. Sites facing difficult to connect directly to the Internet created gateways and accessed it for sending mails. But in case a site has a discontinuous connection then it used UCCP and waited for the gateways between the net and these networks.

States of development of the Internet

The internet is growing and would become a massive platform for sharing information in some or the other form. There are many browsers used for accessing the net. First one was Netscape navigator. Now there are many like Internet Explorer, Mozilla Firefox, Opera, Google Chrome etc.

How a web server works

How a web server works?

The term “Web Server” is a program (the term can also refer to the computer the program is running on) which in simple terms acts like a delivery agent between the clients (web browsers) and the World Wide Web (or the internet). The communication Protocol here is HTTP (Hyper Text Transfer Protocol); hence sometimes a Web Server is also called a HTTP server.

How a web server works

A brief overlook of HTTP

HTTP is the “language” or protocol using which computers on the World Wide Web talk to each other. The client asks for specific files/pages/data to the server and the server returns the request. All the communication done is through HTTP. These are predefined set of rules and thus form a protocol between the client and the server. HTTP 1.1 is the current version used in the World Wide Web.

The Client Side

The client (Web Browser) talks the server with a Universal Remote Identifier (URI). This has many components, first defines the Protocol to be used. Most of the time it is HTTP but other protocols like Ifap, FTP and Malto too can be sent. A Web Server recognizes only HTTP and returns Error for others.

The Connection

The browser connects to the server on port 80. This is usually the case when no port is specifies in the URL like http://xxx.zzz.com:436. Here 436 was explicitly specified.

The Server Side

Every server has an IP address. After the client establishes the connection with this IP address and requests for a specific page the server looks at the file extension of the requested page. If the client requests for a file that is a simple HTML or an HTML extension then the web server fulfills the request and processes the file to the browser. If the client has requested for a page that needs to be processed by a web application server then a web server passes the request to the application server. Now the application server takes over and processes the file/page and returns the results to the web server. Following which the web server returns the request with the desired file/page. The purpose of the web application servers is to interpret the programming instructions and generate the page that a web browser can interpret. They help in the construction of dynamic web pages by the developers.

How a web server works

The operations which take place

The user types in an address, e.g. www.address.com in the web browser and a socket will be created which will allow the client to send/receive data (bytes).

The HTTP request is created by the browser (after examining the URI and the HTTP method).

After a successful/valid HTTP request a connection is made using the TCP connection port 80.

The web server examines the request, if valid processes it.

Fetches the required page and returns it back to the client. If the web server fails to fetch the requested page then it returns ERROR.
