takeitonboard.com...bandwidth and throughput so when we are evaluating our experience of
the internet on our computers at home and we are wondering how fast we can get connection
form a web server to a computer into our houses we are thinking about speed and how fast is
that data running down the line...as quick as it can...
speed...how fast does that web page load...how fast does my youtube clip load up
when you are sold broadband you are sold bandwidth so you are not specified broadband from your
supplier in terms of how fast this data is moving down the line at you...you are sold
based on how fat the pipe is carrying the data
so imagine this data is a stream of water if we have a fat pipe...and a skinny pipe
up above it...you'd go for the fatter pipe which can carry...MORE
so broadband with a wider bandwidth can carry more data
the problem with that specification is that your supplier is only letting you know about
the data that is connecting to your house at the end of the line...but what about the
journey before you get to the end of the line??? is there a narrower part...
to the connection??
This would limit the speed at certain points have you got a narrowing in your connection
in your house that's not enabling you to gain the full advantage of the quoted bandwidth..
Are you splitting out the signal between multiple devices in your house.
Is your playstation on the go?
Is your TV on the go?
Is you laptop on the go all at once ...a mobile phone dragging data at the same time through
the wifi in your house??
Splitting out this bandwidth...
so how do you measure the speed of connection to any given device?
So whats the difference again between throughput and bandwidth...
Bandwidth again measures the pipe...throughput measures how much of this data actually comes
through the pipe... so for example iff your supplier says you
are getting 50 megabytes per second you might go to a speed test website and see that your
throughput is measuring that you are getting only some of the 50 mbps coming through to
you...
For example you may only be seeing 20 of that 50 mb coming through to you...than the throughput
is Download speed is how fast you are getting
data ...FROM the world wide web servers to your computer at home...
Upload is how fast the data is moving from your computer to the world wide web
Review In this tutorial we looked at the speed of
connection to the web and broke it down into 2 ways we can measure it..the first one is
the way that he internet service providers like t sell us the connection speed...bandwidth...which
describes the maximum capability of the pipe that's coming in giving you the broadband
you should be measuring throughput to evaluate the experience that you have
this measures how much of the broadband is coming your way to your device
this can be limited by interference in the line...narrowings in the line at different
points...splitting of connection between different devices within your own network
We then broke down into 2 classifications...the upload speed describing how fast you can send
data up to the web...the download speed describing how fast the data comes to your computer form
a web server...
Thanks for watching
