Ah, well, ps is one program that is Unixes’ analog to the task manager. htop shows the same info dynamically and with pretty colors.

I won’t explain their output here, there are plenty of tutorials and explainers on the web. Just gonna say that in Unixes, background services, including system ones, run under their own names instead of anything like svchost — i.e. a proper separate program starts and keeps in the background, so you can see it in ps or another system monitor. (Although in theory nothing prevents there being an svchost with the same approach as in Windows, but Linux distros don’t provide one for lack of necessity.)
