What can we do with a 2 GB RAM based Raspberry Pi computer? Can I host a website? And what more can I do before the resource usage reaches its the threshold?

It's a fully blown computer that can run Windows 10 IoT and Linux such as Ubuntu or Raspbian (which is Debian for Raspberry Pi) and some other Linux distributions. Some clever developers have even managed to run normal full Windows 10 ARM Edition on it although the performance is simply too far away from good to use it properly everyday.

So just imagine it as a quad core VPS with 2 GB RAM and lets say 64 GB storage (if you get the 64 GB µSD card - more if you attach stuff by USB3.0) or an older laptop. Since it is real hardware you can do pretty much everything you want. All packages of Debian/Ubuntu are at your command and can be installed through the usual apt commands. This includes the full LAMP or LEMP stack to host websites. Or even Java to run a Minecraft server.

What limits it a bit is the ARM CPU. Not all software around the world is available for ARM. So you might not be able to run a CS 1.6 server on it or many other game servers. However web servers, mail servers, DNS, VPN, IRC and etc. are all possible.

It may have passed by you but actually around the world some datacenters even offered free or very cheap colocation for Raspberry Pis and sold Raspberry Pi as products for hosting. The daughter "Scaleways" of "Online.net" has had their own dedicated ARM servers that were like the Raspberry Pi but had a better CPU (quad core ARM 64 Bit CPU with 2.1 GHz) and 2 - 4 or even 8 GB of RAM.
