This determines how much you can store on your site.Bandwidth: Bandwidth is the amount of data that can be retrieved from your site within the bandwidth period. The bandwidth period is the length of time before your bandwidth gets reset once again, usually about a month. Bandwidth is measured in MB and GB, like disk space. Always find out the consequences of exceeding your allocated bandwidth before you purchase a hosting package

Domain Name: The domain name is your personal identifier on the Internet. This is what gets typed into a web browser's address bar to reach your site. Some hosting companies will offer a domain for free, while others will have the facilities to provide one for a minimal cost.SQL (MySQL, SQL Server etc.): Structured Query Language. This is the language used to interact with databases. Chances are that if you don't know about it when you start looking for web hosting, you're not going to need to know about it for at least a little while longer
