    Software is a collection of coder programs that run on your computer. 0:04
    Software is considered soft because you can change it all the time. 0:09
    You know those app updates you get? 0:13
    Well, that's a developer changing their software. 0:15
    Other examples of software are Internet browsers, operating systems, and 0:18
    even desktop applications like Word or Pages. 0:22
    Most software falls into two major categories, application software and 0:26
    system software. 0:30
    Application software is probably the most familiar to you because you 0:32
    probably use applications all the time. 0:36
    When you fire up Word, Spotify, or 0:38
    your Internet browser you're firing up application software. 0:40
    System software is a little different. 0:45
    It's designed to operate and control the computer's hardware and 0:47
    provide a platform for running application software. 0:51
    These include operating systems, utility software, and device drivers. 0:54
    The languages that are used in system software are usually more 0:59
    directly accessing the physical hardware of the machine. 1:02
    As a general purpose user, you might take system software for 1:06
    granted because it runs in the background. 1:09
    But this software is the foundation for 1:11
    all other software you'll run on your computer. 1:13
    Within application software there's special programs used to process code, 1:16
    called programming software. 1:20
    These are editors, debuggers, compilers, and linkers used to translate and 1:22
    combine computer programs into executables, which end up as binary. 1:27
    Some software products combine several of these into one product, which is 1:33
    then called an integrated development environment, or IDE for shorts. 1:37
    These programming tools can come in many forms, but the tool you'll most commonly 1:42
    use here on Treehouse is a robust text editor and terminal called Workspaces. 1:46
    So, how do you write software? 1:53
    I thought you'd never ask. 1:55
    You have to program it, of course 1:57
