1 00:00:15,180 --> 00:00:20,670 Let us start a new section in this section, will the complete testing lab for you? 2 00:00:21,420 --> 00:00:22,980 Let's start with the lecture. 3 00:00:23,340 --> 00:00:27,960 In this lecture, we are going to see introduction to Linux operating system. 4 00:00:29,360 --> 00:00:35,900 From smartphones to cars, from home appliances to supercomputers, from home desktops to enterprise 5 00:00:35,900 --> 00:00:39,080 servers, the Linux operating system is everywhere. 6 00:00:40,100 --> 00:00:46,370 Linux has been around since the mid 1990s and has since reached a user base that spans the globe. 7 00:00:47,150 --> 00:00:54,860 Linux is actually everywhere, its phones, your thermostats in your cars, refrigerators and televisions. 8 00:00:55,280 --> 00:01:02,360 It also runs most of the Internet, all of the world's top 500 supercomputers and the world's all the 9 00:01:02,360 --> 00:01:04,550 stock exchanges use the Linux. 10 00:01:05,330 --> 00:01:08,240 But besides being the platform of choice to run the desktops. 11 00:01:09,140 --> 00:01:15,200 Linux is one of the most reliable, secure and very free operating system that is available in today's 12 00:01:15,200 --> 00:01:15,410 world. 13 00:01:15,830 --> 00:01:16,970 So what is Linux? 14 00:01:17,450 --> 00:01:22,850 Linux is an operating system or kernel distributor and an open source license. 15 00:01:23,300 --> 00:01:25,640 Its functionality is quite like Unix. 16 00:01:26,060 --> 00:01:31,070 The kernel is a program at the heart of the Linux operating system that takes care of the fundamental 17 00:01:31,070 --> 00:01:37,580 stuff, like letting hardware communicate with the software Linux operating system or the kernel with 18 00:01:37,580 --> 00:01:44,060 germinated as an idea in the mind of young and bright, a person named Linus Torvalds when he was a 19 00:01:44,060 --> 00:01:51,380 computer science student, just like Windows, iOS and Mac OS, Linux is an operating system, in fact 20 00:01:51,560 --> 00:01:54,020 one of the most powerful platforms on the planet. 21 00:01:54,830 --> 00:01:59,770 To put it simply, the operating system manages the communication between the software and your of it. 22 00:02:00,200 --> 00:02:06,620 The Linux operating system comprises several different pieces that bootloader kernel in its systems 23 00:02:06,800 --> 00:02:11,420 Damons graphical servers, NextG environments and applications. 24 00:02:11,960 --> 00:02:17,910 Linux has evolved into one of the most reliable ecosystems on the planet that combines reliability with 25 00:02:17,910 --> 00:02:19,220 the zero cost of entry. 26 00:02:19,430 --> 00:02:22,480 And you have the perfect solution for every desktop platform. 27 00:02:22,880 --> 00:02:23,540 That's right. 28 00:02:23,810 --> 00:02:29,210 Zero cost of entry, as in free Linux, the free open source operating system. 29 00:02:29,690 --> 00:02:35,150 You can install Linux on as many computers you want without paying not a single penny. 30 00:02:36,410 --> 00:02:42,920 Linux now enjoys popularity at its prime, and it's famous among the programmers as well as a regular 31 00:02:42,920 --> 00:02:44,690 computer users around the world. 32 00:02:45,290 --> 00:02:48,620 Its main benefits are it offers a free operating system. 33 00:02:49,010 --> 00:02:54,440 You just do not have to shell hundreds of dollars to get OS like Windows being open source. 34 00:02:54,740 --> 00:02:57,680 Anyone with prior programming knowledge can modified. 35 00:02:58,400 --> 00:03:05,240 The Linux operating system now offers millions of programmers applications to choose from which are 36 00:03:05,240 --> 00:03:06,200 most free. 37 00:03:07,100 --> 00:03:10,700 Once you have installed Linux, you no longer need an antivirus. 38 00:03:10,910 --> 00:03:13,040 Linux is a highly secure system. 39 00:03:13,430 --> 00:03:19,250 More so there is a global development community constantly looking at ways to enhance its security. 40 00:03:19,520 --> 00:03:23,870 With each upgrade, the operating system becomes more secure and robust. 41 00:03:24,650 --> 00:03:30,050 Linux is the also of the choice for server environments, the stability and reliability. 42 00:03:30,800 --> 00:03:35,780 Mega companies like Amazon, Facebook and Google use Linux for the servers. 43 00:03:36,530 --> 00:03:45,200 A Linux server could run non-stop reboot for years to end, but users who are new to Linux usually shun 44 00:03:45,200 --> 00:03:51,410 it falsely, considering it as a difficult and technical OS to operate but to state the truth. 45 00:03:51,710 --> 00:03:57,740 In the last few years, Linux operating system have become a lot more user friendly than their counterparts, 46 00:03:58,010 --> 00:03:58,760 like Windows. 47 00:03:59,210 --> 00:04:03,410 So trying them is the best way to know whether Linux suits you or not. 48 00:04:04,170 --> 00:04:11,030 There are thousands of Linux based operating systems, most of them of a state of the art, security 49 00:04:11,030 --> 00:04:13,670 and applications, and all of them are free. 50 00:04:15,250 --> 00:04:20,260 In the next lecture, we'll see the overview of Kali Linux operating system.
