Yes, assuming it doesn't already have the maximum amount.
Go to Crucial and download the little app that examines your system and recommends RAM upgrade options.
Their prices are good but don't have to buy it from them - determine what you need and buy it from Crucial or OWC / MacSales.MacBooks iMacs iPods AirPorts, OS X Mountain Lion, 27 years Apple!

Thank you. I have 1GB on my IMac. Can I install more memory myself or should I take it to the Apple Store?

You can install at least 6 GB on your 2008 iMac, perhaps more. Check the Crucial website and download that app.
It's an easy do it yourself project. Apple even provides the instructions (*)
So do Crucial and OWC. All you need is a screwdriver.
(*) Apple's specifications say 4 GB is the maximum. The reason is that was all there was available for them to test in 2008. If Crucial or OWC say you can install more then you can install more.
