In simple words, Bandwidth can be defined as amount of data transferred from host server to other devices. Bandwidth is measured in similar quantity for space i.e is GB.
For example, Lets say, One website has page size of 1.4 MB and it is completely loaded on two different device, so total bandwidth will 2.8MB.
It is irreversible, It can’t be reversed. Crawlers also use some bandwidth for extraction of data. It is also good measure to calculate traffic on website.
Deletion of files on server doesn’t reduce bandwidth but reducing the page size can help admin to save the bandwidth of the server.
Ya, bandwidth is amount of data transferred from server to load a website or any data related operation that require data transfer.
Reducing the page size means using less size css,js files or images related to the webpage. So how much data is uploaded to hosted server doesn’t relate to bandwidth. Only data that is transferred to load the website is related to bandwidth. To reduce the page size, some of website on the internet are mostly based on text content, they try to use limited amount of image or compressed image to reduce the page size and bandwidth.
Bandwidth is directly proportional to page size of website.
Is bandwidth like a limit that you can use 2 Gb per month or is it like total you can use in your whole server life span
2GB per month means that only 2GB total amount of data can be transferred in a month. But it does not mean that it’s your whole server life span. It will be renewed after one month. It works similar to data limit on mobile network sim inside the android phone.
It means that bandwidth is the amount of data that can be transferred from a website. Also please elaborate the statement:- Deletion of files on server doesn’t reduce bandwidth but reducing the page size can help admin to save the bandwidth of the server.
