[@allenjoseph1659]

Thanks Mrs Bair for such a wonderful lesson! I think this was the most easiest way to explain such a complex thing!

[@skybldev]

A bit of correction: 1) The way the video displays the mouse input to the computer is through a, quote 'USB Port' at 1:02, although the way it explains it is with the old PS/2 system. PS/2 works by system interrupts, essentially directly telling the computer every time it makes an action. USB mice on the other hand is kind of the other way around. The computer asks the mouse (or peripheral) if it's gonna do something. If it sends something back in response to that, then that is represented as a movement. 2) Computers nowadays don't use the BIOS to accept/send data externally. Just because it's called the 'Basic *Input/Output* System' doesn't mean it's responsible for handling data sent from peripherals. Back in the MS-DOS days, the BIOS provided a hardware apstration layer, which basically was a system for allowing peripherals to communicate with he OS and applications. Today, the operating system -- or if we step farther back -- the CPU accepts and sends data to external peripherals or devices *directly*, while the BIOS is simply a firmware that tests system components or peripherals, and loads the computers operating system(s). In my honest opinion, this video should be updated with the correct information hopefully soon.

[@fidelpalma5164]

I thought the same. And have a doubt with 3:30 because I'm not sure if the ask the the actual image to know what button was, that sounds quite unefficient

This is a bit embellished but accurate. For all the people talking about how shitty it would be to be a CPU. Your CPU does all the number crunching. Organization is done for it by other components, the most notable one being the north-bridge chip which is responsible for memory control for the CPU, remember 1:18? It falls near into that category. The computer is constantly running at its own speed, you screw it up, the BIOS allows a moments time for your data to be processed. Either way, most new CPUs nowadays have an integrated memory controller. That being said, I just love the intricacy of computers. Everything is completely accurate and it's a great video. :D Just remember your CPU doesn't deal with your bullshit. Your bullshit is organized and queued up for your CPU to handle at its own speed. It does the hard number crunching. It's got more brawn with brain then you think.

[@jeffread6593]

This reminds me of the old show Bits & Bytes. The younger generations need stuff like this to understand what's going on inside their computer. A minor nit: the BIOS is not what generates interrupts from the mouse to the CPU. That would be an external controller chip, such as a USB controller, in concert with a device driver, a piece of software that lets the CPU understand the data the mouse is providing (including that it comes from a mouse). But that's complicated. :)

They used 1's and 0's to assign values to everything. then they used the values to create a list programming language (which looked like "HGJGHD") where basically you create a list of things u want the computer to do.

[@hotdoh]

I have built several computers, and I learned things from this video that I didn't know before. You really don't need to know much about how computers work in order to assemble the pre-manufactured parts into something that you're able to install operating systems (like Windows) onto. With that said, I agree that those who have built computers are, on average, liable to know more about the very basics of how computers function. Sorry. :( My quick "how they work" might go like this: A computer is like a human. We both take in energy. Humans eat food and digest with their metabolisms; computers eat electricity and digest with their power supplies. Humans think according to logical rules aimed at producing a "tangible" result in some regions of the brain; computers do this with their CPUs (Central Processing Units). Humans recall short term memory from some regions of the brain; computers do this with RAM (Random Access Memory). Humans also have a long term memory, and for computers it's either their HDD (Hard Drive Disk) and/or their SSD (Solid State Drive). Everything that makes a human work is interconnected and "plugs into" what is often generically referred to as a body, and with computers everything literally plugs into its motherboard. Humans have genetic information and environment; computers have software (such as Windows or Linux, or Internet Explorer or Firefox) and people manipulating UIs (User Interfaces (like mice and keyboards)). Humans sweat moisture with their skin to dissipate heat; both dogs and computers move air to accomplish this goal; dogs use their lungs, and computers use their fans. We give off heat as a byproduct of our metabolisms, and so do computers through their power supplies and the components connected to them (everything I've listed and more). Hopefully that helps. :)

[@empyrionin]

+hotdoh I think what he means by "built" a computer is not what you mean by that word. Assembling and connecting pre-made parts is not "building" any more than solving a puzzle is "solving the designing of a puzzle".

[@hotdoh]

empyrionin Well what do you mean by built? Did he gather the elements required to create a computer from beaches and forests with which he literally constructed the entire thing all by himself? Not at a job with the use of company processes or preexisting machines or where some people make some part and others make others? How much of anything does one person make? "If you wish to bake an apple pie from scratch, you must first invent the universe." -Carl Sagan

[@empyrionin]

***** While you can discuss the "turtles all the way" argument, the definition of the verb "to build" is more encompassing than that of the verb "to assemble". Using "to build" in lieu of every part of this continuum (from dust to engineering, to PCBs, to assembly) degrades the work of those who really "build" computers. In my country this confusion is so emblematic that people are incapable of making the distinction between a company that does its own engineering like Samsung, and local Chinese-importing companies. To an engineer, it's vaguely insulting because it looks like the "hold my beer" argument.

Well since hard drives are mechanical, they have a tendency to slow down. But the main cause will be all of the programs that have been installed on the hard drive over the year that haven't uninstalled properly or just run at the computers startup and are not really needed. Another reason can be that when programs are installed and uninstalled a lot, all of it's information can be scattered around at different parts of the hard drive, taking longer to read all of it. Defragmentaion can help

[@utsavjohari4416]

I can explain computers in half that time.

There is a small microphone at the desk that gives orders to the worker to do its thing. That part is the user moving the mouse, clicking, typing, etc. The worker is the CPU, which reads the stuff from the books (Hard drive disk/solid state drive) and does work on the sheet of paper with a pencil (Random Access Memory (RAM) ). The end. See? Very simple and no misinformation is given, hell this could be narrated in less than 60 seconds.

@1:00 she says the mouse button click sends position information to the computer. This is wrong, a mouse has no concept of its position. A button click only tells the computer that a click has occurred. The computer already has the on screen mouse pointer position stored in memory. It's only if the mouse is physically moves that it sends to the computer how much it has moved by, then how the computer interprets that movement information is entirely up to the program running.

if it took this long for a button click to work we wouldnt use computers

today you find CPUs at a clockspeed of 3ghz, that is 3'000'000'000 hertz (pulse) every second.. a mouse click to execute the program that plays the program might need around 150-550 pulses depending on many factors, this is not for playing, just telling the program to play a paused video that is already loaded and ready in the memory xD

My friend: CPU isn't the programing center of your computer. Me: What? My friend: I said CPU isn't the programming center of your computer. Me: Yes, it is. My friend: Prove it. Me: [this video] My friend: Oh you're right.

Now that’s cringe ngl

The CPU is not a great multitasker. It can compute millions of operations per second but never more than one at a time. That's why the mouse click is called an interrupt. Of course modern day computers have multi core processors that make this possible.

Back in my day, we didn't have fancy mouses and typewriter-boards! We used Hollerith cards and were darn grateful for 'em too! Only joking... mostly. I do remember using the Apple IIe computer, which didn't have a mouse, and had a 5.25' floppy disk drive. *KER-CHUNK!*
