Hosting Websites Web hosting is an online storage service for information, images, video, or any content accessible through the Web. 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.
