The Bus | How the computer works?

In the earlier days of computers, parts [like the CPU and the RAM] were not contained within a single IC board. They were mostly separated in individual cabinets. Information traveled from one cabinet to another by bundles of wires, called a busbar - which later became to be known as a bus.

Are the lanes at 1:10 basically traces on the mobo?

[@DrDAC-go7hs]

Really good video. I still have the question about bus sizes. How does a bus increase in size when multiplexers are involved? Do you just increase the size by adding another 16 lanes and add more multiplexers?

[@huyvuquang2041]

A bus is unidirectional (one wire). A lane is bi-directional (two wires).

[@DuyAnh-ul3jn]

Hey dude,do buses have a shape like a big wire in the power supply,or a physical object?Sorry,I cannot understand what you said because I'm a non-native English speaker:((

[@NotezOnTek]

I’m not sure I understand your question, but a bus is generally a wired connection- like a usb cable which stands for Universal Serial Bus.

[@DuyAnh-ul3jn]

[@DuyAnh-ul3jn]

[@NotezOnTek]

I’m still not sure what is it you are asking. The buses that this video is referring to is for sending bits of information, not power.

very nice vdo.. u'll go big just wait❤

[@androidmode2799]

Using multiplexer it is passed using two clock cycles , so how doesn't it impact performance.

[@NotezOnTek]

The more lanes a parallel bus have the more prone it is to crosstalk. Because of this parallel buses have to operate at a slower clock cycles. This is why a serial connector like USB is faster than the old parallel connectors. Because USB even though it uses multiple clock cycles, it does so at higher clock speeds.

[@viczking8520]

so buses are bundles of wires? is it copper wire or which material?

[@NotezOnTek]

It can be copper or anything that’s conductive.

[@nafiurpial7209]

Great!

Thanks for this uploading this vedio

[@androidmode2799]

Serial bus has only one lane , so it can be also called as "buss with 1 bit of size" ?

[@NotezOnTek]

There are serial buses with multiple lanes. The point is that the lanes work independently whereas lanes in parallel buses have to work together. I hope this helps, we are heading into more advanced territory.

[@androidmode2799]

@@NotezOnTek Got it, thanks for clear explanation :)

[@leen8374]

What's a lane ?

[@NotezOnTek]

A single wired connection, like usb which uses one wire to transmit and one to receive data.

[@masterunknown4303]

Does it matter in gaming

[@NotezOnTek]

Well it depends. Older computer used the AGP standard which is parallel. but today's PC use PCIe, which is a high-speed serial bus.

[@masterunknown4303]

@@NotezOnTek iam planninf get the xeon E5 1620 V2 or xeon E5 1650 both of them uses a socket from 2011 or 2013 does it matter in those cpus because both of them do not have bus speed or qpi links

[@amirulasyraf9900]

anyone can confirm my understanding? does this mean computer bus basically mean ether 16 bit or 32 bit?

[@NotezOnTek]

Well if you are talking about lanes, yes in theory a 16 lane bus could handle a 64bit memory address by breaking down into four parts. Remember the number of lanes does not necessary determine the size of the bus. Keep in mind that a 64bit computer means that its memory and register size are 64bit, it does not mean that information will travel in 64bit chunks down a 64 lane bus
