If you are unfamilliar with Web Hosting let me explain.
Every site on the internet needs to be stored somewhere,
every facebook post every google image, every netflix
show is on a special type of computer called a server. These
servers are kept on 24hours a day and never switched off
as evertime someone opens a website, or views a
youtube video they need access to the server where this
data is stored.

So your website needs to be stored on a server. Servers
hold an insane amount of data and and store thousends
of websites on a single server tower. So depending on
how much space you need on a server, your hosting
package will vary. Think of it like paying rent for your
website to live on the internet.

The server provider should be reliable, we use Liquid Web
who use emergency generators so they will never have a
power owtage, the server rooms are tempriture controlled
so servers will never over heat and motion detectors and
tight security makes sure no hackers can access the server
rooms
