How Computers Work – Journey Into The Walk-Through Computer
[Recorded 1990] How Computers Work: A Journey Into The Walk-Through Computer is an educational video produced by The Computer Museum and hosted by David Neil of PBS’s Newton’s Apple. Join David Neil and his four young companions on an entertaining and illuminating trek through The Computer Museum’s one-of-a-kind, two-story working model of a desktop computer. The Computer Museum in Boston, Massachusetts was the predecessor institution to the Computer History Museum located in Mountain View …

The computer really doesn’t know, but that’s what the output looks like. For example, if that letter, or group of 8 bits, is stored in RAM, then if a program (or 0′s and 1′s) calls out those specific bits or letters and tells it to be written on-screen, the graphics processing unit will get a picture of the letter “Q” and draw it on-screen.
Maybe you should delete your youtube account then.
no but thay make sum
thank you for your opinion. I’m sure I’d never have read it without whatever it is you’re trashing.
I almost forgot how the things were like in those days.
I started using Sun workstation in 1990, and it had SPARC processor running like at 30MHz or so. Before that, I used PC with 286 and a separate floppy drive for 12 inch floppy !!
And all I could access on internet was Newsgroup, but good thing was we didn’t have to deal with internet trolls.
this is 1990! now we have hp touchsmarts and macbook pros
Do you have to get the trackball registered as a weapon nowadays? That thing looks like a murderous cudgel that is designed by Apple.
lol
@11:28, holy moley, look at the size of that… what’d he call the hard drive? a hummer? i’ve never once heard that.
We are only just seeing how micro-processing technology has helped end the world. Its so unhuman, it seperates us, it makes all jobs the same, it turns people into cabbages.
Wow, I have been looking for this since seeing it years ago in elementary school. Thanks for the upload!
Trackball lol…. it didn’t quite catch on did it!
Quotes from the Past
1981 640K ought to be enough for anybody. (Bill Gates)
1982 I don’t know what the language of the year 2000 will look like, but I know it will be called Fortran. (C A R Hoare)
1983 No one knows what to do with 7 windows at one time (PC Week magazine)
1984 The Macintosh uses an experimental pointing device called a mouse. There is no evidence that people want us these things. (John Dvorak)
Abolish computers!
Those ons and offs (binary) represent decimal numbers, there is a standard called the ASCII table that defines wich number represents wich letter and this is why we know that Q is the 81th character, but since we are dealing with a computer we have to represent it in the binary system, so 81 in binary=1010001. If you wanna learn more, start with wikipedia and work your way from there, there is a lot of ground to cover
Oh wow, so 1337, you’ve booted linux and written a terminal program. That’s just amazing.
Well 01010001 is the binary for the ASCII letter Q. How the CPU knows that that is ASCII Q, I don’t know. It’s probably the way the circuit is set up.
but how does a computer even “reads” and “understands” those ons and offs at the first place? i mean how did it know that a combination of those ons and offs is what it represents, which in this case is the let Q?
i was thinking this was a joke, but it’s not bad.
I think it’s the same basic principals, just a lot faster and more efficient.
Lol trackball
at 25:28 you can see the lighting be held over his head.
There needs to be a remake of this video focusing on nowadays computers.
An entire novel?? WOW!! LOL
For a second, at 1:04 I thought that girl had HUGE gauged out ear lobes.
