languages, our expressions come from everywhere. They come from nature,
sports, and food. They come from money, culture, music, history! If you
name the area, we can find a special word or expression that comes from
The word we will talk about today comes from technology: bandwidth.
The first definition of “bandwidth” is the range of frequencies within a
given band, especially when used for sending an electronic signal.
In computing, it means the largest amount of data that can be passed
along a specific path. For example, if you are making a video on your
computer, it will use more bandwidth than if you were simply creating a
When we talk about ourselves (and not our computers), bandwidth has a
Human “bandwidth” refers to the total number of issues or amount
information a person can deal with at any given moment. It is the
emotional or mental space you need to do something or think about
When you have lots of bandwidth, you can deal with anything life throws
at you. But, when you are really busy or seriously worried, you might
not have the bandwidth to deal with any additional issues. You simply do
not have the time or mental space.
We have other expressions that mean almost the same thing as being out
of bandwidth. I can say I’ve hit my limit. I'm up to my neck, up to my
eyes or up to my ears (you can use any of those body parts) with work,
responsibility or fill in the blank. I am swamped!
“Bandwidth” can also simply mean your attention span.
For example, let’s say you are sitting at your dinner table thinking
about an all-consuming problem. In this state, you are not able to focus
on anything else. So, if someone tries to ask you a question, you can
tell them, “Sorry. I do not have the bandwidth to talk to you right now.
Come back in about an hour!”
Now, sometimes we use the word “bandwidth” when we talk about our brains
as computers. An article in Scientific American gives us a good example
of this usage.
Writer R. Douglas Fields discusses the development of an electronic
device worn on the arm that permits the wearer to mentally interact with
a computer. He writes, “This achievement opens and expands the bandwidth
of the brain’s output.”
Sometimes people use “bandwidth” to simply mean mental ability. I might
say: “Oh, do not to try to explain the issue to Alex. He doesn’t have
the bandwidth for something so difficult.” Used this way, it means
"Alex" is not intelligent enough to understand. It is a clear insult.
So, be careful using it that way.
Now, let’s hear "bandwidth" used in this short conversation between two
Okay, let’s go over the shopping list. We don’t want to forget anything.
Do we have to do that right now?
No. But the party is next month. So, time is running out.
There’s plenty of time. And right now … I have a lot on my mind.
Come on. You can’t be that busy.
Oh really? Well, today at work, I lost all my documents when my computer
Well, you have back-ups of all your documents, don’t you?
No. I had just finished writing three long stories. I’ll have to work
overtime the rest of the week or I’ll miss my deadline!
Maybe we should change the subject.
Sure. This morning my sister called to tell me that my great aunt died.
Oh, I’m so sorry.
That’s okay. I only met her once when I was 10. But my mom can’t take
care of the funeral plans. So, now I have to.
Oh. That’s going to take a lot of time.
Yes, it is. But that’s not all. Last night, my apartment flooded from a
leak in the pipe! So, I have to fix it by tomorrow because my boss is
coming over for an important dinner meeting!!
Wow. You are swamped! Really up to your neck.
Tell me about it! So, please understand if I don’t have the bandwidth
right now to plan for a party that is a month away!!
Well. Sounds like someone is out of patience as well as bandwidth.
