But what do we really mean when we - -3 -00:00:06,130 --> 00:00:09,980 -use the term software? Software is an abstract description of - -4 -00:00:09,980 --> 00:00:13,920 -a set of computations that becomes concrete, and therefore useful, only - -5 -00:00:13,920 --> 00:00:16,600 -when we run the software on some hardware, and that, - -6 -00:00:16,600 --> 00:00:19,310 -in the context of some human activity that it can - -7 -00:00:19,310 --> 00:00:22,530 -support. So what does that mean exactly? What that means - -8 -00:00:22,530 --> 00:00:25,235 -is that when we say software, what we really mean is - -9 -00:00:25,235 --> 00:00:28,790 -a software intensive system. That is, the combination - -10 -00:00:28,790 --> 00:00:31,930 -of 3 things, the software, the hardware on which - -11 -00:00:31,930 --> 00:00:34,610 -the software runs, and the context in which the - -12 -00:00:34,610 --> 00:00:37,470 -software is used. Just to illustrate, let me show - -13 -00:00:37,470 --> 00:00:40,010 -you this through a picture. What I'm showing here - -14 -00:00:40,010 --> 00:00:42,830 -is a customer, a user, that is using, is - -15 -00:00:42,830 --> 00:00:47,000 -accessing, an ATM machine. And this action involves several - -16 -00:00:47,000 --> 00:00:50,650 -things. There is the software that drives the logic - -17 -00:00:50,650 --> 00:00:53,410 -of the ATM machine. There is the hardware on - -18 -00:00:53,410 --> 00:00:57,280 -which the software runs. And there is the context - -19 -00:00:57,280 --> 00:00:59,850 -In which the software is used. And in this - -20 -00:00:59,850 --> 00:01:02,660 -case, the context is the bank. And only by - -21 -00:01:02,660 --> 00:01:06,105 -considering these 3 things together can we really understand - -22 -00:01:06,105 --> 00:01:09,510 -the functionality that is represented here. So the bottom - -23 -00:01:09,510 --> 00:01:12,690 -line here is that we usually take hardware and - -24 -00:01:12,690 --> 00:01:15,750 -context for granted in this equation. But they actually - -25 -00:01:15,750 --> 00:01:18,210 -need to be explicitly considered when building a - -26 -00:01:18,210 --> 00:01:20,770 -system. Otherwise, we might forget this is all - -27 -00:01:20,770 --> 00:01:23,850 -the functionality, and ultimately of the requirements. And - -28 -00:01:23,850 --> 00:01:25,640 -we might end up with the wrong system. -- cgit 1.4.1
