What is an Operating System as Fast As Possible

[@mikeklaene4359]

Computers have been around a lot longer than PCs. You have to go back at least the 1950's to get the first operating systems. The first OS's with which I worked were those designed for the IBM 360 system in the late 1960's. And even then they supported multi-tasking and had true memory management that protected one user's data from other processes.

[@danielagutierrez1186]

Hi!! My name is Daniela Gutiérrez and I’m from a school in Mexico!! Thank you so much for uploading this video! I think that it has very complete information, it’s quite interesting knowing the complex process that it takes to a computer to do such a simple seeming task!!

[@EpicLPer]

I knew you guys used the Fluttershy squee in one of your earlier videos (Firewall). This video proves it (2:08). *EDIT:* Well seems they used it here too at 3:40

[@DragonF1re31]

I do have to say it has been weird and awesome to hear you guys talk about stuff I learned in college this semester. Keep doing what your doing Linus, loving it all!

[@ShiroVitae]

My college class requires me to watch this video!!! I love these random rewards. ❤️

[@dc2008242]

0:06 What about a Penguin? WHAT ABOUT LINUX, LINUS? YOUR NAME IS PRACTICALLY LINUX! XD EDIT: I notice it like a second later AND in the description

[@H20z1]

dc2008242 It's practically Linux because the guy who first designed a Linux operating system was called Linus. The OS is named after him not the other way around

[@dc2008242]

lol

[@sauron1427]

dc2008242 Linus Torvalds to be exact ^^

[@williamskagen9901]

dc2008242 If you use Linux you probably know what an operating system is :P

[@sauron1427]

***** ...except it's more stable, more secure, lighter to run, faster, and 100% free. As well as infinitely customizable. You got it the wrong way around, there's no reason to use anything BUT linux unless you really need a program that only works on a different platform.

[@zeroisgawd1442]

So basically Windows, OS X, or linux uses bootstrapt, which goes into the automatic booter of the CPU and then as soon as you interact with the system it sends out requests made out of binary code to the CPU every millisecond to enable you to move the cursor and more and the system uses graphical design to display images onto the video card. then you can open multiple programs with multitasking which is pretty self-explanatory. It sends out more requests to the cpu in order for the system to open up multiple tabs of things.

[@MikeDragon]

This episode of _As Fast as Possible_ is definitely 20% cooler than the other episodes.

[@vgamesx1]

michael weiss Making a joke = fan of something, Right... you must be the fan around here.

[@michaelweiss2186]

vgamesx1 Not sure what you are referring to, perhaps you could elaborate a bit? My point is that FreeBSD is what OSX is based on, plain and simple. Just like Android is based on Linux, not that hard to figure out. not sure where the "joke" comes into play per this discussion.

are you a computer engineer or something????

[@CodeShay7]

[@jyotikrishna5762]

Just something

[@LUMINIZEDOG]

I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.

[@LUMINIZEDOG]

you both fell for the b8 lol

[@ivztfdwbn254]

[@davidgrisez]

I am old enough to remember the C/PM and MSDOS operating systems. Back in those days any program could access all the hardware directly. The programs did this to speed things up on these slow computers. About the only thing the operating system was used for was disk drive input and output of files.

[@threescoops8672]

Could you do a video explaining what Optical Drives are and the things to consider when buying one? Just a thought, the internet seems pretty sparse on this subject.

[@LeonoraTindall]

LinusTechTips 3 videos on Operating Systems and only about 30 seconds about Linux and no mention of BSD? Really? Also, while Windows and Mac OS X have built in user interfaces, Linux and BSD do not. Even in Windows and Mac OS X, the UI is a userspace process for security reasons (except, for some reason, font rendering in Windows.)

[@Niosus]

WayZHC In a sense the kernel is what defines the OS. It does all the important work. Everything else is just thrown into the package for convenience for the end user.

[@Niosus]

WayZHC I know very well that a kernel alone is useless, just like a car is useless without a steering wheel. That doesn't mean that the collection of Linux distros has a lot of things in common. There are a lot of general things you can say that hold true for nearly all UNIX-like OSes. Anyway. Who really cares about the "overal" comparison. Use the right tool for the right job, use what works for you.

[@LeonoraTindall]

The OS is the kernel plus the libraries and tools required to interact with it. That may or may not mean GUI, but Linux by itself is definitely not an OS. It has no interface at all, not even a shell.

[@LeonoraTindall]

Quinn Wood If that were the definition, GNU/Hurd would have no operating system since any part of it can crash and the OS will recover.

[@LeonoraTindall]

Quinn Wood, BSD is an operating system, Linux is not. Linux is a bare kernel. GNU/Linux is an operating system.

[@raulsanchez4716]

Awesome video. Great explanation. Also, I enjoyed playing that Tomb Raider game, had a lot of fun.

[@christiangab1227]

Thank you for explaining what an Operating system you are truly awesome and wonderful ^^

[@rontarrant]

Perhaps you could settle an argument, Linus... A friend of mine said last week that contemporary Windows versions still using paging at the hardware level. I have a hard time believing that. So, is it true? Does Windows 10/11 still use 640k pages when addressing memory at the hardware level?

[@alwaysasn]

3:43 What a weird time to use an MLP squee sound clip.

[@danielmouse5436]

[@eugenepohjola258]

Howdy. Back in the days of DOS 5 it was said the OS manages files and folders. Win 3.1 was said to be a graphical interface to the OS. Files are generated with applications. These days these distinctions are blurred. Also has hardware management become an important part of the OS. Regards.

[@supersophisticated9943]

I had an argument once where someone tried telling me that windows 10 isnt a program/batch there-of...

[@1495978707]

Hey the case at 0:10 is mine!

[@TheHareidGamer]

Linux as fast as possible? Like what makes it special, pro's and cons. Also, could you please do a 1 month with linux thing like you did with OSX?

[@HeyItsHades]

what makes most linux distros fast is because the kernel and OS are very minimal. They hardly have any bloatware to slow down the machine. They run what is necessary and that is it. Further, there is constant active development on the linux kernel done by millions of people everyday so they can tweak, and tweak, and tweak code the maximum performance.

[@johneygd]

I bet that if apps gets ported from android to ios and visa versa, that all they need to do is use is a device driver and/or change the encryption key for it to be accepted by that other operation system.

[@EngineeringVignettes]

Continuing on in your series, may I suggest the wonderful subject of Memory Managers (MMU, MPU, Virtual Memory vs physical memory, memory access violations, the luscious SEGFAULT/SEGV that torments many beginner programmers). Also, did you already cover the Windows BSOD? If so my bad.. I have not watched all of these yet... (historically Win32 not the first OSes to see these, I grew up being annoyed at Amiga Guru Meditations many times). Nice set of topics so far...

[@AslanexMetrobus]

You seem to confuse drivers with compilers. A driver is not needed for any system, only for peripherals or ADVANCED features.

A question that popped into mu head while watching this. Would killing explore.exe help improve game performance? Not that I need that on my pc but curious. I have a gaming pc and I wouldn't see any difference as far as I am aware.

[@stonium69]

About a year late, and I don't have Windows, so I cannot check for sure, but probably not. Any file managers worth their salt don't use any CPU when they are in the background, only a little bit of RAM. Unless you are running out of RAM on your system, it won't really give you any performance boost.

[@Yadnus912]

Not sure how easy it would be, but I have a suggestion for tech quickies. You could possibly cover the osi model? And if its a stupid idea, please don't comment hate :/

[@dj420j2]

Sorry i'm dumb, but is it like, if someone make a computer, then when your on that computer, you need a OS, but there is like hardwares CPU screen and stuff but to like make it work and do things on it, you need an OS?

[@xplinux22]

alex kohm The problem is that many of the installed drivers don't match the new hardware. Suddenly the OS is struggling to communicate with the hardware, and more often than not may BSOD (or kernel panic for you Linux, BSD, and OS X users).

[@erikschiegg68]

In principle, an OS is a set of rules how to operate a computer and causing you to shout frequently "oh shit!", therefore the abbreviation OS for oh shit!

[@themangix357]

Just a question, I don't own a Mac so I don't know, do Macs have drivers? I watched this certain video once asking professors of a certain University about Macs and PCs, and Mac owners generally loved their machines because it didn't need to install any "confusing drivers", just run and go.

[@skifree0]

ApexPredator_ yes there are drivers, like any modern operating system. The only difference is the update channel goes through apple rather than the user, which actually leads to the confusion of whether OSX has drivers to begin with. Because apple hardware is typically very vertically controlled, all drivers are prepackaged into os updates rather than a separate installation. its tightly controlled and certified. so to answer your question both claims are correct, there IS a driver, but you still can just "run and go" as its all preloaded into the os.

[@USER69473]

ApexPredator_ search about hackintosh installation and you will know =)

[@xplinux22]

ApexPredator_ Oh, they have drivers all right. Anyone who has built a Hackintosh rig knows the pain of loading the right *.kext so the OS doesn't go belly-up if the hardware doesn't match Apple's specifications 100%. The reason drivers are rarely a problem for Mac users is that the hardware it is distributed with is tightly controlled and the OS comes preloaded with all of the drivers it needs, out of the box. Unfortunately, it is literally impossible for OS X talk to anything unsupported by Apple, and it will fail very noisily if you don't carefully and diligently select your hardware beforehand, as Apple provides no fallback drivers and no safety guarantees. Third party official drivers are basically nonexistent for Macs, and Apple clearly states the illegality of writing and freely redistributing them without explicit approval. However, that certainly doesn't stop the Hackintosh community from patching and writing custom *.kext drivers of their own so people can use OS X with the latest whiz-bang video cards and whatnot.

[@UntouchedWagons]

How does an OS keep track of what program has what block of RAM allocated?

[@LeonoraTindall]

UntouchedWagons There is a thing called a Page Table that keeps track of what physical memory maps to what virtual memory. The OS then keeps a table of which pages belong to which processes.

[@EngineeringVignettes]

UntouchedWagons MMU, (Memory Manager Unit) which manages the page table. Essentially each program runs in the same memory space (starting address is constant) but these assigned memory spaces are virtual.
