Internet speed, the number they give you (5 Mbps, for example), has nothing to do with how fast your internet works. It’s not like a car or motorcycle where you can measure how fast it goes in miles per hour (mph).
Instead, internet speed is your (allocated) bandwidth. Bandwidth is the amount of data that can be sent to you, usually measured in seconds. For example, 5 Mbps would mean that you can receive up to 5 megabits of data per second.
Another confusing aspect of shopping for internet based on speeds are all the terms or abbreviations being used. Mbps, MBps, kbps, Gbps; what does all of this mean?
These are the abbreviations for the amount of data that is being sent per second. Here is what each of them mean. Below that I’ve outlined a basic conversion guide and a rough idea as to how big each piece of data you consume is.
kbps – Kilobits per second. This is used when talking about dialup (56k for example) and low speed DSL.
Mbps or mbps – Megabits per second. Some people confuse this with megabytes. The difference between the two is how the “b” is written in the abbreviation; Mbps = megabits and MBps = megabytes. This is the most common unit of speed used.
MBps – Megabytes per second. Megabytes aren’t usually used in (residential) internet plans.
gbps – Gigabits per second. Gigabits are hardly used for internet plans, and the costs make them unpractical for families and small businesses.
To give you a better idea how much bigger or small each unit of speed (bandwidth) is, here is a handy conversion chart. You can also visit Numion and play with their calculator.
Bytes ==> Bits: Multiply by 8
Bits ==> Bytes: Divide by 8
Mega ==> Kilo: Multiply by 1,000
Kilo ==> Mega: Divide by 1,000
Giga ==> Mega: Multiply by 1,000
Mega ==> Giga: Divide by 1,000
Giga ==>Kilo: Multiply by 1,000,000
Kilo ==> Giga: Divide by 1,000,000
Here are some things that you do on the internet and how much bandwidth (and data) it uses up:
1 Web Page – 1 MB
1 Text Email – .97 MB
10 Min YouTube Video – 43 MB
Download 1 Image – 2.5 MB
30 Min of Gaming – 2.5 MB
Another confusing thing about shopping for internet is when you see speeds listed like this:
5/1 Mbps
What does this mean? Well, that means that internet plan has a download speed of 5 mbps and an upload speed of 1 mbps.
The reason why your upload and download speed are different is because most internet connections are asymmetric. In English this means that the bandwidth is a different size going one way compared to the other. Since most users consume content rather than upload it, the bandwidth for download speeds is larger (than the upload).
There are a number of things that will (negatively) affect the speed of your internet.
Connection type plays a big role in how fast of an internet connection you’ll have. Using my analogy from earlier, some roads (bandwidth) are fixed or capped — they can’t be widened or increased. Dialup, and to some extent DSL, are perfect examples of this.
It just goes hand in hand with internet speeds.
Anyway, your internet can become congested just like a freeway can. The more data (or cars) that is being requested and sent, the more bandwidth (freeway lanes) that is being used at one time. At some point every lane is going to be taken up, so the cars (data) will take more time to get to you.
Congestion usually happens during peak usage times, like when everyone gets off work and logs onto the internet. But you can also experience slower speeds if you have a home network (and everyone is online) or someone using your wireless connection from outside your home.
Think of bad wires and connections like a freeway that goes from 5 lines to 1 all of a sudden. That forces all of the cars (data) to bottleneck, ultimately taking longer to get to you.
The same thing holds true for your equipment. If you have outdated equipment, or your equipment isn’t configured optimally, that can slow down how fast you receive your data.
The further away you are from your ISP (hub) the longer it’ll take for the data to transfer from the internet to your computer.
