Sure.
There are several different ways you can try out Linux, depending on how far you want to go at the moment.
Live CD
Distributions such as
Ubuntu offer what is known as a 'live CD'. You download the .iso, burn it to a disc using an ISO burning program, then boot your PC from the CD.
It takes longer to load than normal and will generally be more sluggish than a real install, but you can have a play around and experiment all you like, without touching your current computer setup. Note that anything you change in the Live CD system will be deleted when you shut down, so save any documents to a memory stick or something.
This is the best option for just having a peek into the world of Linux to begin with. If you want, later on, you can...
Dual Boot
Dual booting means that you install Linux alongside Windows. You'll need to resize your Windows partition on your hard drive (the installer can do this for you), then when you start up the machine you'll have the option of booting into Windows, or Linux.
This process is more complex, potentially risky (you'll have to back up first), but it offers full speed and a complete Linux experience. In addition, Windows is preserved so you always have the option of using it when it's appropriate, and Linux when it's appropriate.

I'd recommend you try out Live CDs first. That's the quickest and easiest way to take a look, have a play around, without affecting anything currently on your system. Later on, you can then try installing if you want more, but you probably want a bit more experience first.
Hope this answers your questions! :)
