The executables are located in the /usr/bin folder. I guess pressing Alt+F2 and typing

skype

will do. It might also fall under the Applications menu > Internet.

To uninstall already installed software, you can:

  1. Goto Software-center. Find the software and remove.
  2. open a terminal, and type

sudo apt-get remove <software-name>

If you do not know the complete name, just type a few characters of the application, and press tab twice. That will auto complete, or show a list of matching applications.

You don't need the whole path when using Alt+F2 (or the terminal or desktop/panel shortcuts). Just typing skype will suffice. –  sepp2k Oct 23 '10 at 11:31
    
Oops, overlooked that! Thanks for the heads-up. But there was a time that I had to give the entire path. Dont remember the applicaton now. –  theTuxRacer Oct 23 '10 at 11:45
    
You have to give the full path if you don't install it "properly"... –  8128 Oct 23 '10 at 17:43

You can discover where a package puts its 'stuff' by running:

dpkg -L 'packagename'

There's still a set of 'standard' locations that programs are put into. For example, binaries (in windows parlance 'executables') are put in /usr/bin, and documentation is put in /usr/share/doc in a Ubuntu system.

This is a pretty simplistic answer. For more details about how linux/unix directories are typically structured, see this:

There are some very good answers to a similar question to yours over at

What is the equivalent to the Windows "Program Files" folder?

But the general idea is that the /bin and /usr/bin are where the start up application files (executables or scripts) are stored. The direct equivalent of "Program Files" though is probably /usr/share this is the directory that contains the various support files for most applications

For a good overview of the Ubuntu file structure check out the link below.

Many of the files in /bin and /usr/bin are scripts, but more are actual binary executables. –  Eliah Kagan Jun 16 '12 at 4:56

There is no "Program Files" Directory in Linux. The Application's Parts are distributed according to what they are. There are a lot of explanations of the Directory Structure out there, you can use this one for a start.
