i always see this word here and there.
just tell this!
USB stands for universal serial bus...it is a type of port on ur computer which lets u connects other devices such as printers, cameras, input devices, etc. now USB 2.0 simply denotes the type of port...first there was USB 1.0, then came USB 1.1, and now we have USB 2.0
USB 2.0 is currently the latest....
Nemesis is very right.
One more thing I want to add is If u have device Which support USB 2.0. It will definately run on all version USB ports i.e. 1.0, 1.1 and 2.0.
But if u have an old devive which supports USB 1.0 or 1.1 then it will not run on heigher version USB ports.
USB 2.0 can also send/receive data at a MUCH faster rate than 1.0 or 1.1.
u mixed it all up
usb 2.0 doesnt work on 1.0/1.1 ( if it is ONLY usb 2.0 compatible )
and usb 1.0/1.1 works on usb 2.0
usb 2.0 max speeds = 400 ( or was that 480) mbps
dun remember the speed of the other ports now !
Just Check This Link
u also find other unknown things via
usb 1.1 had max data transfer rate of 12mbps and usb 2.0 has 480mb/s. wot he was trying to say was a usb2.0 device will work on a usb1.1 controller but the transfer speed will be limited to 12mb/s and usb 1.1 devices will work on usb2.0 controller wid a max speed of 12mb/s. hope that clears things.
ok i looked it up for further clarification
like it says .. PROBABLY ....
again like i said backwards compatibility means usb 2.0 and usb 1.1 compatible
if the device is ONLY usb 2.0 compliant it will NOT work on usb 1.1 port
Separate names with a comma.
