In this tutorial we will learn about the different web hosting .

Web hosting refers to the service of providing storage space and access to websites and web applications on the internet. When you create a website or web application, you need a place to store all its files, such as HTML, CSS, images, videos, and databases. Web hosting companies offer servers that are specially configured to store and serve these files to visitors who access your website.

There are many type of web hosting such as.

1.Shared hosting

2.VPS hosting

3.Dedicated hosting

4.Cloud hosting

1.Shared hosting

In shared hosting each customer has to share space and resources on the server with every other customers, including CPU time,memoryand disk space.

it is cheaper and doesnot required much technical knowledge for hosting on shared hosting. similary there are limited software application, it is slow and security at risk because of shared resources.

simple example of shared hosting is like we live in a room with the many friends, we have limited resources and if one friend damage any resources(like bulb) then we all need to paid for that .

2.VPS  hosting

it referes to virtual private server which offers a shared environment as well however, its technology partitions all its users. (like some cpu,memory,disk e.t.c are partition for a particular users)

it is affortable but quite expensive then the shared hosting, it required technical khowledge,it is fast and scalable as well.

it provide root access and you can install any software as well, similary it is suitablefor small and mid business.

simply example is like that you are in a house and each friends are living in each room . each are responsible for their resources,space. if some one damage then invividual are responsible not all the people living in the house.

3.Dedicated hosting

it is the server that is fully dedicated to one user who has the right to use all the resources available. it is quite expensive and also required technical knowledge as well. it is much faster and secure.

it is mostly used for the large busniess, which has high performance. it has full access to all setting and can customization.

simple example is like , yopu sit in own private house, you can do any things you want , used any resources at any time for any things . it is totally private.

4.Cloud hosting

it is cloud base hosting where we host resources on cloud server . we will learn more about it in future.

lets learn more about the shared web hosting.

For shared hosting firstly you need domain and the web server to host website and can make easily access for the public. so firstly you need to buy any domain and web hosting server according to the requirements. then web hosting will provide ypu cpanel , through which you can perform any task easily.

How to add unlimited domain in the shared hosting.
