Software

[MUSIC] 0:00 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
