Outlines
🌐 Understanding Internet Speeds and Bandwidth
This paragraph discusses the concept of internet speed and how it relates to bandwidth. It clarifies that advertised speeds by internet service providers (ISPs) are not actual data transfer rates but represent the maximum data transfer capacity, measured in bits per second (BPS). The analogy of water flowing through pipes is used to illustrate how bandwidth affects the amount of data that can be transferred. A smaller pipe (lower bandwidth) allows less data to flow through compared to a larger pipe (higher bandwidth), even though the flow rate is the same. The paragraph also introduces the concept of upload and download speeds, emphasizing that while ISPs advertise download speeds, upload speeds are typically lower and less critical for everyday internet use.
📈 The Importance of Upload Speed for Businesses and Streamers
The second paragraph delves into the significance of upload speed, particularly for businesses and content creators. It points out that while high download speeds are crucial for general internet use, such as browsing and streaming, a faster upload speed is essential for those regularly uploading large files or live streaming. The paragraph highlights the disparity between advertised download speeds and the actual upload speeds provided by ISPs, which are often a fraction of the download speeds. It concludes by encouraging viewers to subscribe for more content on the topic of bandwidth.

hello everyone have you ever thought
about the speed of your internet
connection well chances are yes you have
because when you were shopping for
high-speed broadband internet for your
home or business one of the first things
you thought about was speed such as
upload and download speeds and as you
were shopping you may have seen internet
service providers advertising broadband
internet speeds of 100 megabits per
second 500 megabits per second or 1,000
megabits per second well these speeds
that are advertised are technically not
the speed at which data travels over a
network but it's actually a measurement
of the maximum amount of data that's
transferred over a network and this is
what's known as bandwidth bandwidth is
measured in bits per second or BPS in
other words it's a measurement of how
much data is transferred over a network
in 1 second so for example if you have a
100 megabit internet service connection
then that means that a maximum of 100
megabits of data can be transferred in 1
second or if you have a 500 megabit
connection then that means that a
maximum of 500 megabits of data can be
transferred in 1 second so even though
the 100 and 500 megabit connection
transmit data at the same speed the 500
megabit connection will seem like it's
faster because it can transfer five
times times more data in 1 second than
the 100 megabit connection so this is
why internet service providers advertise
their internet connections as
speeds so as an analogy we can use an
illustration of water flowing through a
pipe and depending upon the diameter of
the pipe it will directly affect how
much water can flow through it so the
smaller diameter pipe will represent a
lower bandwidth connection and the
larger diameter pipe will represent a
higher bandwidth connection so as you
can see the flow of water is traveling
at the same rate in both pipes but since
the bottom pipe is wider than the top
one it's able to flow a lot more water
at the same time more than a smaller
pipe which can fill up the container at
the other end a lot
faster hey guys before I continue I just
want to thank my sponsor for this video
which is brilliant and Brilliant is

annual premium
subscription so this works just like an
internet connection if both both of
these connections were to download a
video from the internet that's 4 GB in
size the 500 megabit connection can
download the video to your computer a
lot faster so in theory the 100 megabit
connection would take about 5 1 12
minutes to download a 4 GB video while
the 500 megabit connection would only
take a little over a minute or if some
of you were old enough to remember this
if you were us if you were using an AOL
dialup connection back in the 1990s
using a whopping 56k BPS connection
using your phone line it would take you
about a week to download a 4 gigabyte
video now this is providing that AOL
doesn't randomly kick you off your
connection and no one in your home wants
to use your phone because this will
cause you to disconnect and then you'll
have to reconnect and you'll have to
restart the download all over again from
scratch so again these calculations are
just on paper because in the real world
there's internet traffic lag and
equipment that would affect the actual
time it takes to download but needless
to say the more bandwidth you have the
faster and smoother your internet
experience will be but also the higher
the bandwidth the higher price you'll
have to pay your internet service
provider now keep in mind bandwidth is
measured in both download and upload
speeds but when isps are advertising
their internet speeds such as 100 or 500
megabits per second they are referring
to the download speed and typically the
upload speed would be only a fraction of
the download speed so for example if an
ISP is advertising a download speed of
100 megabits per second the upload speed
may be around 10 megabits per second now
the reason for this is because the
download speed is what's most important
when regular consumers are doing normal
things such as browsing websites
watching videos writing emails and so on
so having a high upload speed is not
really important but if the consumer is
running a business and they are
uploading large files on a regular basis
or if they are a live streamer for
example on YouTube well then having a
faster upload speed would be needed so
guys I want to thank you for watching
this video on bandwidth Please Subscribe
and I will see you in the next video
