Web hosting is an online program for people to store information, videos, pictures, etc. Web hosts provide space for customers on the internet in order for them to create web pages. Generally, web hosts are only adequate for personal home pages, as larger, more intricate sites require more complex packages with database support and development platforms. Most people get there start using free hosting however, free web hosting is very limited when compared to paid hosting, since they have a small disk space, and require you to have your own ads on your site. Shared hosting is paid hosting where your site is on the same server as many other sites. Some problems with shared hosting is that if something goes wrong with one site, it effects all of the other sites as well. There are also a few restrictions with shared hosting, although these are not even close to how limited free hosting is. Dedicated hosting is paid hosting which can be quite expensive. You will have your own server with dedicated hosting, and there are virtually no restrictions. Dedicated hosting is more expensive than shared hosting because there is a never ending supply of addresses for dedicated hosting. However, dedicated hosting requires you to have an http server certificate, FTP access, and a domain server name. If you are just starting out with creating web pages, most people would recommend using free hosting at first. After upgrading to shared hosting, you can then decide if dedicated hosting is for you.
