Unity is a graphical shell for gnome 3, and it is the default graphical shell used for Ubuntu.
The primary means of accessing programs is from the unity launcher bar on the left side of the screen.
Simply left clicking any icon once will launch that program, right clicking the icon will give you options.
Using the right click you can choose to keep programs in the launcher or remove them.
At the top of the launcher is the dash icon which is represented by the ubuntu logo.
The dash will allow you to find or access programs that are not displayed on the launcher, as well as files and media.

to view a list of installed software, and filter the results.
