Web Hosting - Your Web site host is the physical location of your Web site. It's where the data associated with your Web site resides.
Your Web hosting provider will maintain the computer, called a server, which your Web site lives on. They will also manage the technology that makes your Web site work and connects it to the Internet. When you're choosing a Web hosting company, you'll be asked to make decisions about how much data storage and data transfer you need. Don't be too concerned - you can always increase your quantities if you find you need more.
