the term usb gets thrown around a lot

but very rarely do you see anybody

explain what it is now usb stands for

universal

serial bus

and that's s-e-r-i-a-l

now let's break down each of those words

first of all

universal

what this means is it's a physical

device that is built according to a

universally accepted standard

all around the world if you're making

something that conforms with this usb

idea

it's got to be made to exact physical

standards in its construction and

operation it's universal meaning

accepted universally

now let's go to the last letter there

bus b-u-s

in computers there's lots of data

transferring back and forth both inside

the computer and to other computers or

devices

it travels on wires it's electronic data

so it's just electricity but there's a

special term

for a wire or collection of wires that's

meant to carry data electronic data and

that term is bus

so inside the computer you'll have lots

of collections of wires running this way

and that between different parts of the

computer

and in order to get data out of a

computer you can have

a bus and what this means is

there's a spot on a computer

that you can plug something into where

data can either go into the computer on

it or out of the computer on it so

that's where the word bus comes from in

universal serial bus or usb

and finally serial when we're looking at

transmitting data transferring data back

and forth between devices

you can either send the pieces of data

along one wire so a one piece of data

moves another piece of data moves

another piece of piece of data moves and

they go all in order one after the other

or

you could actually have several wires

that simultaneously can carry data on

them

the difference between these two

different modes of operation is called

serial

where there's one wire

and the data travels one piece after the

other or parallel where there's multiple

wires each of which can be carrying some

of the data that you need to move

so

a universal serial bus

is a standardly accepted and constructed

method

for devising a physical component

along which you can transfer data

between computers and other devices and

that data is transferred one item at a

time

in serial

now let's look at what they look like

so

this giant piece right here it's called

a motherboard and you don't need to pay

too much attention here except to know

that this is inside a typical computer

and on this big giant board are most of

the important parts of the computer that

do the work now

this little section right here this is

something you'd see on the outside of a

computer and it's where you can connect

things you can connect things like a

keyboard or a microphone or a mouse or

that sort of thing you know a printer

you know a display but you'll see right

down here

two different ports side by side and

these are

universal serial bus or usb ports this

is where you make the physical

connection and you can see that inside

those are hooked directly into this

motherboard so data can go out through

these to whatever device is connected or

from that device in through here and

into the motherboard and again this

relates to the overall concept of why

you have a computer in the first place

which is its purpose to take in data

work with that data and send that data

on and a usb connection is one of the

primary ways to do that one most

commonly accepted here's an example

of a usb

connector and you can see this connector

will actually go

right in now that actually went in the

first time one of the other things to

know it's a common joke is that

every single time you try

you'll get it backwards have to flip it

over and it'll actually plug in so there

you have it a usb physical connector

the usb port where it goes onto a

computer

and the purpose of it it's a way to

allow data to come into and be sent out

of a computer
