When discussing web hosting, it is about a company, which offers a space server where you can host your site file. It also provides internet connectivity that allows your computer to access files on your site.
You should note that your website consists of a broad range of images, HTML, and videos. To set up your site and share 
content on the internet, you need a super server with high-speed internet connection.
It is necessary to understand the difference between the data center and web hosting. It refers to the server, which hosts your site. It can also imply the hosting company that rents its server space. Data centers are facilities, which houses the servers. It can be big room or small room.
There are four major types of web hosting: Dedicated, Virtual Private Server, Shared, and Cloud Hosting. Such servers function as centers that store your website. These differ in storage capacity, server speed, technical knowledge requirements, reliability, and control. It is crucial to look at deeper differences among the various forms of web hosting.
Shared Hosting
It is known as shared hosting because the site shares same server with many other sites. They can range from very few to thousands of websites. It is possible for domains to share the same pool of various servers such as RAM. The good thing about this type of hosting is low price. Most of the sites that are hosted under this plan have modest traffic. It is known to be entry level alternative that requires very minimal technical knowledge.
Dedicated
This is a server, which offers optimal control on the internet where your site is stored. This means that you have the server 
all to yourself as it only your site, which is hosted there.
VPS hosting
This form of hosting that splits the server into the various virtual server. Therefore, each website is hosted on its server but it is simply sharing the same server with just a few users. The good thing about this type of hosting is that you have your very own space and a safer working environment. It is great for sites, which need adequate control at the server levels. It is a better option for webmasters that do not want to spend a lot on dedicated servers.
Cloud hosting
This is a hosting meant for sites that receive very high traffic. In this case, a group of servers is designed to host various websites.
