How to choose the right bandwidth for your website
Bandwidth is the amount of data your website can transfer from the web hosting server to the client or web browser when your page is requested and rendered. Most web hosting companies will grant you a fixed or unlimited amount of data to transfer in a month depending on what type of plan you sign up for.
Moreover, it is the developer responsibility to write code to make good use of the bandwidth. So making sure you’re implementing a good caching strategy, or spreading your files across multiple servers (i.e place your images on a image hosting website and your scripts elsewhere). Not only will it increase the rendering speed of your site, but it’ll create a better browsing user experience.
