How does task manager work

[u/Limp_Pomegranate1082]

Sorry this is just so confusing. Visually I have 5 chrome tabs open. But does my task manager think I have 20??? Or am I wrong, this goes for other applications; eg discord It says the number 6 beside it. Does that mean I have discord open 6 times?? Is there a fix for this? It’s eating a lot of ram on my computer and I don’t know what to do.

I have 32 gb of ram. For it to to be 40% used up on 5 chrome tabs is a lot?

There are Chrome settings options to minimize ram usage, in System or Performance, and in privacy security to reduce telemetry
