Web hosting is the service that makes a web site available to others on the internet. Basically when you rent web space you are renting disk space on someone's computer which is connected full time to the internet. Of course technically it gets more complicated than that, but that's the basic definition. There are literally thousands of web hosting services available today. Some web hosts offer general web hosting for all, while others focus on a specific industry or niche of hosting. As an industry, web hosting is almost a phenomenon. Considered to still be in its infancy, web hosting is growing at a pace of $16 Million a day!
