Despite what you may have heard, your computer could have 40 or more legitimate tasks running concurrently. Most of them will be critical software components for windows and/or applications. However, many of them are not necessary.
Some of the tasks will be associated with programs you have running such as Virus checkers, web connections etc. svchosts is just a generic term which means another particluar process is running.
I currently have 32 processes running, but only one application, this IE window.
If you want to eliminate any unnecessary proceeses, which may be slowing your computer down take a look here:

You can find almost all the tasks you're likely to have running and help as to what they're doing and whether they're necessary, unnecessary or downright dangerous.
