With more than half of the world dependent on the internet, it has become the need of the hour that every one of us, regardless of your career interest, should know the fundamentals of the internet concepts.
Many a time, while we are chasing behind the latest technology, we tend to forget that we can grow our knowledge only on a strong base.
As we know that every concept in science has evolved from theory, we must constantly try to make our fundamentals stronger, even if we know them. So having said all of these, let us quickly brush up the basic yet most significant fundas of the internet.
Basic Internet Concepts
- As the name suggests, the Internet is a global network of networks.
- It connects millions of users worldwide via many computer networks.
- The TCP/IP communications protocol is a simple standard common addressing system and basic communications protocol, which helps in this communication.
- Apart from being connected to the world, some of the internet-based services also include FTP, Telnet, Usenet News, WWW and so on.
- Tim Berners-Lee is the Web inventor.
- He founded the World Wide Web Consortium (W3C) and aptly defines it as: The World Wide Web is the universe of network-accessible information, an embodiment of human knowledge.
- URL (Uniform Resource Locator) specifies addresses on the World Wide Web and its format is as:
protocol://hostname/other_information
- The Website (a collection of pages) sits on the Web server which connected to the Internet. Latest Web servers are? Apache, IIS, Lighttpd, and Jagsaw, while the expensive ones are - Netscape's iPlanet, Bea's Web Logic and IBM's WebSphere.
- A Web server is given a unique address. It is made up of a series of four numbers between 0 and 256 separated by periods. For instance:
68.178.157.178
- DNS (Domain Name System) helps the browser to find the IP that hosts the Web site you want to visit.
How Internet works
-
You enter a URL of the Website into a Web browser and request to access it.
-
This request is passed to a domain name server.
-
The domain name server returns the IP address for the Web server that hosts the Website (for example, 68.178.157.178).
-
The browser uses the IP address specified by the domain name server and requests the page from the Web server.
-
The Web server hence returns the page to the IP address specified by the Web browser requesting the page.
-
The Web browser collects and consolidates all the information and displays to your computer in the form of Web page.
Internet Protocols
-
Protocols are a set of rules and Internet protocol means a set of rules that are governing the format of data sent over the Internet or other networks.
-
The task of delivering packets from the source host to the destination host is done by Internet protocol (IP).
-
It is based on the IP addresses in the packet headers.
-
IP defines packet structures that encapsulate the data to be delivered and defines addressing methods.
-
Addressing methods are used to label the datagram with source and destination information.
-
Initially, IP was the connectionless datagram service in the original Transmission Control Program which was introduced by Vint Cerf and Yogen Dalal in 1974.
-
The connection-oriented Transmission Control Protocol(TCP) is one of the main protocol of the internet protocol suite.
-
TCP originated in the initial network implementation in which it complemented the Internet Protocol (IP) and therefore it is often called as TCP/IP.
-
The first major version of IP and the dominant protocol of the Internet is Internet Protocol Version 4 (IPv4).
-
Its successor, Internet Protocol Version 6 (IPv6), has however started to come into the picture and has reached almost 25% of the Internet traffic as of October 2018.
