Bandwidth is a somewhat erroneous term. People use it to describe a few different things. Hosting companies will refer to bandwidth as a consumable item (ie: 1000 GB bandwidth included), networking folks refer to bandwidth as a unit of measure (ie: 5 MB/s), and others refer to bandwidth as the capacity of a network.
Here is a nice video from Cisco:

When giving a lesson on basic networking concepts, I draw this same highway on the whiteboard but I also bring in a large clear Slurpy from the convenience store.
I explain that the tasty mix of slushy drink is data. The cup is the internet. The straw is the physical connection and I am the "computer" sucking up the data (slushy drink) using all of these things.
My "slushy network lesson" is much more effective in person and exceptionally interesting if there is a slushy machine close by for every student to "experience" the lesson :)
In my slushy example bandwidth is the size of the straw. I could use a larger straw (a bigger physical connection) and consume more bandwidth. I could suck harder on the straw to speed things up or if you want to get crazy I could "multiplex" and mix different kinds of tasty slushy blends together.

It means the strength and capability of a network. In layman's terms, if your internet has good bandwidth, you have good internet speeds.
Bandwidth is your downloading and uploading speed. For instance, having a download speed of 30 KB/s is very slow but having a download speed of 750 KB/s is much faster. Upload speed is usually about half of your downloading speed.
Bandwidth simply is the speed at which data is transferred. Sometimes bandwidth is also used to refer to the maximum capacity, or the fastest, that a connection could move data.
Suppose Pipe=bandwidhth; Water=internet. The greater the diameter of the pipe, the more water will flow in a specified time.

In computer networks, bandwidth is often used as a synonym for data transfer rate - the amount of data that can be carried from one point to another in a given time period (usually a second). This kind of bandwidth is usually expressed in bits (of data) per second (bps). Occasionally, it's expressed as bytes per second (Bps). A modem that works at 57,600 bps (57kbps) has twice the bandwidth of a modem that works at 28,800 bps. In general, a link with a high bandwidth is one that may be able to carry enough information to sustain the succession of images in a video presentation.

One of the best way to learn about your bandwidth is to test it. The following site is a very good way to test the speed of your bandwidth and it's fun!

I think of bandwidth as "the size of the pipe". If you can think of the data flowing in and out of your computer as if it was WATER, then bandwidth can be thought of as the size of the pipe carrying that water.
