Computer Tech Solutions : How Does a Microprocessor Work?

[jarrettpeter37]

This video is a favorite on Andorra

[MitchAndo96]

YES! I KNOW, but how does a little piece of metal with little transistors inside it do calculations (even like, 2+2?) how does that work????

[jamesdonlan]

@MitchAndo96 each number is converted into a binery i.e. 01011, on the chip these are recorded on switches like transisters which are either off or on. 0 would be no volts and 1 would be 5 volts. there is a program that tells the chip how to understand these codes and what to do with them.

I like it.

[rubnm5]

Cool explanation!

[LCaaroe]

Sweet

[nvidia290]

100 years ago we had horse and buggys now we have this shit

[SeabasR]

@nvidia290 our technology is growing exponentially! in gust ten years we will be able to have hard drives with 500TB of storage!!!

[Dophoofd]

I started to google on a windows 7 x64 torrent, means microsoft needs to learn how to use a microprocessor? lol

[xSlavic]

f u all

[LuisAceituno92]

It does division by looping subtraction? I understand doing multiplication by looping addition (2x3 = 2+2+2) but how do you loop subtraction to do division? (6/3 is not 6-3 or 3-6 or -6-6-6 or -3-3-3-3-3-3)

[moveaxebx]

@LuisAceituno92 That was a very simple model of ALU. Today's processors contain logic to provide multiplication and division with integeres and floating points. But yes, you could divide by doing something like this in software(instructions) .i.e 21/7 = 3 mov r1, 21 mov r2, 7 mov r3,0 loop: sub r1,r2 inc r3 jnz loop after it completes, register r3 will hold the result. But on today's processors you just do: div r1,r2

[supericy2]

@LuisAceituno92 2 month old comment but might as well answer it anyway. For your example of 6/3 it would loop "-3" until it hit 0. ie 6 - 3 and then 3- 3 and then would return the amount of times looped ie 2.

[LuisAceituno92]

@supericy2 thank you :) I understand now

[DARKNESSRACE]

i love hellow kity!!!

@efendulov hahaha it was 8months ago, i already pass in that module(CSO), i didnt said i don't understand, i was just looking for something more detailed involving DMR, interrupt and transfer of data.

[atalayapark]

I lost interest

[Celinancc1701]

BUT HOW GOD DAMNIT! how the hell do you put numbers into silicon chips? is there some type of electrical signal exchange taking place? WTF?

[Xenophobe74]

@Celinancc1701 There are transistors. Their work is to judge, YES or NO. YES is 1 and NO is 0. There are gates inside transistors, one in each, open or close, 1 or 0, that is binary number. Electrical signals determine whether to open or close. ALU determines what signals to send based on Algorithms. Algorithm is very easy, if u just learn Algorithm, u can understand the whole of computer. It will take u about 1 hour to learn Algorithm in a very good way. Algorithm is a maths based on YES or NO.

[martoksneghvar]

@Celinancc1701 yes the voltage goes through the transistors millions of them it has on and off or 1 and 0 numbers are in the formof the voltage in the transistor turning on and off millions of times a second :)

[moveaxebx]

@Celinancc1701

CPU is nothing more then just a huge bunch of wires and transistors.

What is transistor? A device which has two electric circles. By adjusting the voltage in one circle, you can control the voltage in secondary circle. So transistor can behave like switch.

Great...now you can start building some very primitive logic, like logic gates...using them you can achive more complex tasks like adding two numbers...

ubuntu linux

[CashedUpBogan46]

That was good mate thanks for that

[VadimPVO]

эх если бы было по русски)

[LOGIESPZ]

wait u just said the register n the alu do the same thing the registers dont do calculations n the cu doesnt send them off to be processed it DOES the processing also the registers store data that is waiting to be processed u also didnt explain what ram n rom stand for ir anything about buses i know this but most people watching this dont i watched this to find out what the difderent registers are called but u didnt tell me that either

[arooobine]

@LOGIESPZ Give the guy a break! This was meant to be a quick and simple overview in easy to understand terms, not a detailed account of how everything works.

[LOGIESPZ]

@arooobine i completly forgot i posted that what a prick why did i write a comment that long i think i was stressed because i had an exam the next day any way sorry to guy who uploaded this video thumbs up

[talkybooky]

What I got from this that

the register small ares the store values inside them the cpu do the calculations .

Rom takes the commands from the Motherboard .

Ram do calculations also .

C.U loads in the commands from the ram or the rom and sends them after being processed .

please tell me if I was wrong

my quiz is on saturday.

[arun231990]

@talkybooky heyy ram just stores data for processing

[arun231990]

@talkybooky heyy ram just stores data for processing rom dosent take commands it gives commands

[WaziristanGamerz]

simple but useful... thanks

[Ankit03rock]

hi, sir am a student for computer science, i would like to request u if u could create another videos, explaining the cpu architecture in more detail including the DMR, interrupt and transfer of data.

[Groth1175]

clearest explanation id ever heard, thanks!

[AllDaySCIfi]

They are all von Neumann machines though.

nifty

[cooldeesir]

thanks

great video

[mustapha18]

thnx

[IntrepidMoocher]

Nice, simple explanation. 5 stars!

[TheCraigID]

@IntrepidMoocher or 1 like -_-

[iRobii]

@IntrepidMoocher wow... the good days haha :)

[pericotudo]

This is Ubuntu!!!!!, what version??

[jasonsyx35]

i now know how they work

[Indiareprizzent]

thanks m8 your a champ

[Lipeleez]

Neato!
