Basics About Internet

In this article, we will be briefing about various basic technical terms of the Internet like Web Browser, Domain Name, Protocols etc. which is commonly used in today’s era of the Internet but few of us are not able to define them when asked during an interview because we put very little importance to them.

Today I will be briefing all the above terms and will co-relate the same with examples.

Do you know: Web Browser takes help of search engine and plugins to enhance user experience and work under protocols defined by the governing authority.

Now let’s have some basic understanding of Web Browsers, Search Engines, Plugins, Protocols, Domain Name and Hosting.

What are Web Browsers:

Search engine requires a medium on which they can run and the medium is a browser. Let’s take an example of browser name Google Chrome. The browser basically provides an interface between the web server and user.

Example: We opened Google Chrome and write on address bar a URL / web address. The browser will contact the web server and ask for the relevant information and get back to the user with the desired result.

What is a Search Engine:

Let’s derive the meaning of the term “Search Engine” by splitting it i.e. Search and Engine

Search means finding something and Engine means a force that helps us towards progress in our task. Combining the term Search Engine we have its meaning i.e. “An engine that helps us in searching anything”.

Let’s take the example of a Giant Search Engine i.e. Google.

Google is a search engine having millions of document stored inside it to whom it scans and give us a relevant result when a user hits a search query (search query is the question put by the user to search engine).

Do you know how Google Works?

The search engines like Google.com, BING.com, Ask.com etc. are some popular search engines which are extensively used in order to get the results of users query.

What are Plugins:

These are some add-ons to a web browser which provides additional features to a browser.

Example: You want to go from New Delhi to New York for the same you catch an airplane which is an add-on in this case because you do not have the efficiency to go there without any additional help.

Similarly, Browsers require some add-one to do a specific task for e.g. showing flash content (Flash Player Plugin required), showing PDF file (Adobe PDF plugin required) etc. so in this way plugin comes handy when providing additional feature to a web browser and user.

What are the Protocols:

These are some standard rules that are followed while transferring information over the internet. Under this different Internet, terms come into play like packets (data is sent over the internet in the form of packets), IP Address (Each system has a unique IP Address that differentiate it room others) etc.

URL and Domain Name:

Definition of URL and Domain Name with an example:

Let’s explore what is URL, the most important term of the Internet.

URL stands for Uniform Resource Locator. It is responsible for the following:

  1. Locate a resource over the internet (Web Address) by its domain name (IP Address comes handy in this case)
  2. It also defines the protocol (mostly HTTP or HTTPS are used) used by the web address.
Domain Name

Domain, what is it?

I will keep it simple and short while explaining each topic and will try to co-relate each topic with a live example.

To explain what a domain is, let’s take a website: https://www.onlineseoblog.com/seo-training-syllabus

Let’s split this Web Address into different parts:

  1. HTTPS: The website address often starts with http, https, ftp etc. All the initials of web address are known as Protocol which basically tells the browser how to retrieve a data.
  2. www.onlineseoblog.com: In this section of web address “www” is optional to write (basically used to tell that this website is open on Web where WWW stands for World Wide Web).

Now, “onlineseoblog.com” is the domain name with an extension “.com” which is considered as Top Level Domain.

  1. /seo-training-syllabus: This is the path for the file placed on the server which gets opened when you click on the domain.

Hosting:

Once you have your domain name then you need a place where you can launch that domain in order to become live on the internet. Launching domain over the internet is known as Hosting.
