What is web hosting? | Tom’s Guide

When it comes to building a website, certain things have to happen. First of all, you need to have an idea of ​​what it will be about and what it will contain. Then you have to design and build it using one of the best website builders. Finally, you need to organize the best web hosting, so that everyone can access it. But what is web hosting?

Websites are made up of a series of different files. Some are images and videos that you may have taken yourself or professionally shot, but most are special types of text documents that contain code. When you create a website, all of these files exist on someone’s computer, just like you can store Word documents or PDFs.

When you want the website to be accessible to the general public, you need a special type of computer called a web server. It is essentially another computer, but with higher specifications than most personal computers, and with a dedicated high-speed link to the Internet.

We explain what web hosting is and what you need to know below.

The dedicated link to the Internet is known as a Static Internet Protocol (IP) address. Most home Internet connections have dynamic IP addresses, which means they change periodically. For ordinary household use, this is not a problem. For a web server, however, this can cause downtime and websites hosted on it may be inaccessible.

Static IP addresses avoid this risk and allow web servers to use File Transfer Protocol (FTP). This allows you to easily move files from one computer to another, such as when you upload files for a website from the computer on which they were created to a web server.

Having a static IP address also means that the server can have a Secure Sockets Layer (SSL) certificate, which we cover in our article on how you can assess and improve the security of your website.

The process of setting up static IP addresses and configuring computers as web servers is called web hosting. A whole industry has formed around selling web hosting services, which basically amounts to renting disk space on these specially configured computers.

Web hosting is typically sold on a subscription basis, which also covers the cost of the energy needed to run computers and the bandwidth they use.

Web servers are stored in large specially constructed structures called data centers, which are temperature controlled and extremely secure. A data center will have many rooms, filled with rows of computer towers side by side. It is on these special computers that all the files that make up a website are stored.

As mentioned, a web server is similar to a home or business computer, but with more power and a faster internet connection. You can actually use your own personal computer to run a web server, but websites hosted from it are unlikely to be as fast as those stored on dedicated hosting computers.

It’s also not something we recommend for those who don’t have a lot of time to devote to the task. Running a web server is a complicated and time consuming task that requires specialized knowledge. That’s why hosting companies have their own DevOps (software development and IT operations) specialists who ensure that web servers are always online, secure, and performing.

Website owners had better focus their efforts on the content and marketing of the site and leave the hosting to companies that specialize in this area. Yes, you have to pay for web hosting, but it will save you time and money in the long run.
