Check out this page in Wikipedia, to learn something about Mbps: TinyURL.com - shorten that long URL into a tiny URL
In very basic terms, Ping is about the signal from and to the Server that supplies your PC with the information from your ISP (Internet Service Provider). It's measured in very small increments of time, nanoseconds I think.
The Download speed you have, is something you need to take another look at. It will not be 265 Mbps, that is a fantastic download speed and I would like to move in next door if you had that! It is eother 2.65 or 26.5, but I think it will probably be 2.65 Mbps. That is in line with my own current average of 2.6 download and 0.66 upload. I live in a rural area of Lincolnshire, do you also live in a rural area? we get garbage speeds.
Download is the speed at which information comes into your PC, when you download something like a music album or a game. Upload is when you are trying to send something OUT to someone else. The speeds you and I have are pretty low. To demonstrate this, use another Speedtest - internet-speedtest.net
This will check your speeds, then give you the option to type your FULL phone number in a box. A new window will open, telling you how long it will take you to download Videos, films and MP3 tracks. From this speedtest, the information also goes to your ISP, giving them a record of what your speed is. I carry out one of these every day, at varying times.
Please don't think I am an expert in any way, I am only self-taught and willing to be corrected by other forumites here!
EDIT: RIGHT clisck on the "tinyurl" and choose " Open Link in New Tab ".
