The reason for all those questions is something called “bandwidth” or “transfer”. The amount of storage space a web-hosting plan offers you is usually far less important than the amount of transfer or bandwidth the web host offers youEvery time someone visits your webpage, every file included in that webpage is downloaded from your website to their computer. In other words, from the web host’s computer to the visitor’s computer. This includes each graphic or image on the page, every icon, even the html page itself is downloaded by a user just visiting your webpage. The size of each of those files being transferred to the visitors computer is the amount of “transfer” or “bandwidth” you are using

Let’s say you get 100 visitors per day to your website. Let’s also say that your html page is around 15k and you have 5 images on that webpage that altogether are around 50k. That means each visitor to your website is using up 65k in bandwidth every time they visit that page. Let’s also say your average visitor opens 3 pages within your website and those pages are the same size as your main page. That means each visitor uses 195k minimum and that is if they don’t keep going back to your main pageMultiply that 195k times the 100 visitors per day you get and you are using 19,500k or a little over 19 megabytes of transfer per day. Multiply that by 30 days and you get 585,000k or 585 megabytes of “transfer” or “bandwidth” used per month
