1 00:00:00,000 --> 00:00:01,650 [No audio] 2 00:00:01,650 --> 00:00:05,430 Let's look at Unix versus Linux and see what are 3 00:00:05,430 --> 00:00:08,430 the differences. But before we get into finding 4 00:00:08,430 --> 00:00:12,180 the differences, we'll find out what Unix is. Unix 5 00:00:12,180 --> 00:00:15,390 was first developed for multi user and multitask 6 00:00:15,390 --> 00:00:21,540 purposes in mid 1970s in Bell Labs by ATT, GE 7 00:00:21,600 --> 00:00:24,480 and Massachusetts Institute of Technology, there 8 00:00:24,480 --> 00:00:27,810 was an operating system but it was not allowing 9 00:00:27,810 --> 00:00:32,040 for multi users or multitasking. So that was one 10 00:00:32,040 --> 00:00:36,150 of the purpose for creating that. Then born Linux 11 00:00:36,180 --> 00:00:41,760 in 1991, by a French student named Linus Torvalds. 12 00:00:42,930 --> 00:00:50,100 Linux is mostly free and Linux is open source. So 13 00:00:50,130 --> 00:00:53,220 what Linux free means is you could install the 14 00:00:53,220 --> 00:00:56,370 Linux operating system in any of your computer 15 00:00:56,370 --> 00:00:59,610 hardware. There are a few Linux distributions that 16 00:00:59,610 --> 00:01:02,190 are not free like Red Hat, where you would have to 17 00:01:02,190 --> 00:01:05,879 pay for support and subscription. And the open 18 00:01:05,879 --> 00:01:09,810 source means that Linux code that was derived 19 00:01:09,810 --> 00:01:13,050 from Unix is actually open to the public, to the 20 00:01:13,050 --> 00:01:16,860 community, so they could go in and make changes to 21 00:01:16,860 --> 00:01:19,860 that code and make the operating system the way 22 00:01:19,860 --> 00:01:24,330 they want it to work in their own way. Unix is 23 00:01:24,330 --> 00:01:28,140 mostly used by Sun and the operating system is 24 00:01:28,140 --> 00:01:31,590 called Solaris. By the way Sun is now bought out 25 00:01:31,590 --> 00:01:36,300 by Oracle. And also other operating systems that 26 00:01:36,300 --> 00:01:41,340 are Unix is used as HP-UX by HP, AIX, and some other 27 00:01:41,370 --> 00:01:45,780 distributions of Unix. Linux is used mostly by 28 00:01:45,780 --> 00:01:49,020 developer communities or companies like Red Hat, 29 00:01:49,020 --> 00:01:55,260 CentOS, Debian, Fedora, SUSE, Ubuntu and there are 30 00:01:55,260 --> 00:01:59,040 so many of them even if you go out and search for 31 00:01:59,100 --> 00:02:01,830 Linux distributions you will find so many of them. 32 00:02:02,940 --> 00:02:06,990 Unix is comparatively supports very fewer file 33 00:02:06,990 --> 00:02:09,570 system. Now what is a file system, that is 34 00:02:09,570 --> 00:02:12,449 something that we will cover later, but there are 35 00:02:12,479 --> 00:02:15,180 fewer file system that supported by Unix operating 36 00:02:15,180 --> 00:02:18,600 system and a lot more file systems that are 37 00:02:19,140 --> 00:02:24,360 supported in Linux flavors. Linux can be installed 38 00:02:24,390 --> 00:02:27,540 on a variety of computer hardware ranging from 39 00:02:27,540 --> 00:02:30,270 mobile phones, tablet, video games consoles, to 40 00:02:30,270 --> 00:02:33,900 mainframe, and some supercomputers. It's just like 41 00:02:33,900 --> 00:02:37,710 you cannot install Mac operating system on a Dell 42 00:02:37,710 --> 00:02:40,830 machine. You have to install Mac operating system 43 00:02:40,860 --> 00:02:45,000 on a Mac hardware. Just like that Unix is only 44 00:02:45,000 --> 00:02:48,480 installed on certain hardware, whereas Linux, you 45 00:02:48,480 --> 00:02:51,750 could install pretty much on every hardware that 46 00:02:51,750 --> 00:02:56,100 is out there running AMD or Intel processor. So 47 00:02:56,100 --> 00:02:59,490 these are the few basics about Unix and Linux, 48 00:02:59,730 --> 00:03:02,250 and I hope you will find more information if 49 00:03:02,250 --> 00:03:03,780 you're curious about it online. 50 00:03:03,780 --> 00:03:05,088 [No audio]
