Given the amount of searches conducted for the term
"speed test", it seems that the Internet is passionate about speed.
There are many online testing tools that allow you to check
your upload and download speed.

| What an Internet speed explains? |
In this tutorial I will try to explain how speed tests work
and what speed tests tell you.
In this article you will know about internet speed tests.
- What is the good download speed and upload speed?
- What is Mbps?
- Is 10 Mbps downloading speed is good?
- Does Internet speed change throughout the day?
- Is it worth changing internet service providers to get a faster internet connection?
Understanding the Internet Speed Test
The Internet Speed Test gives you upload speeds and download speeds. Uploading refers to the process of transferring data from
your computer to the Internet, and downloading refers to the transfer of data
from the Internet to your computer.
The download speed is usually much higher than the upload
speed (ADSL). This is usually good because most people download much more
than they upload.
Download speed test work by transferring a known file from a
test server over the Internet to your computer and measuring how long it will
take.
4 MB file takes 8 seconds on 4 Mbit/s link and 2 seconds
on 16 Mbs/s link. Upload speed is measured by uploading the file from your PC
to the test server and measuring the time taken again.
There are many factors that affect how fast your overall connection speed is:
- Technology Access - e.g. ADSL, 4G / 3G Mobile, Satellite etc
- ISP
- Location of your server or service
They all form a chain (communication link). In comparison,
if you drive traffic on a 6 lane road, it becomes a 2 lane road and a 4 lane
road. On the Internet, like a normal road, your final speed is
limited by a slow link in the chain.
Note: You do not need to install any software on your
computer to perform Internet Speed Test. Be very careful when using speed
test sites to install software to improve your computer speed. Some are
probably genuine, but impossible to say, so I don't.
Factors on which
Internet speed depends upon:
- Access technology
- ISP
- The location of the remote resource
- Time of day
Internet access technology
As far as internet access speed is concerned, this is a very
important factor. All methods have limitations. Fiber broadband's connection
speed is much better than 3G mobile.
Your (Internet Service Provider) ISP
You connect to your ISP (using an access method such as ADSL
broadband) and your ISP then connects to the Internet. ISPs advertise the speed of connection to the customer, not
the speed between the customer and the Internet.
Home connection in the UK is almost always BT phone line and
ADSL, but fiber is popular. If so, the access speed will be limited by these BT lines
regardless of the ISP you choose.
This does not mean, however, that all providers offer the
same connection quality -
The relationship between the ISP and the Internet is
generally higher and faster than fiber, but it is shared by many users.
So when an ISP overloads a link to the Internet, it slows
the connection from the subscriber to the Internet.
Location of the service / server on the Internet
The Internet has a vast network of interconnected computers
and networking devices.
The speed of the destination service / server and the number
of routers / servers traveling through the data affects the overall speed.
In addition to the network speed and capability of
connecting these computers / routers, they also affect the final connection
speed.
So you may have a super fast connection to the Internet, but
still take the same time to download a file from the Internet with a very slow
Internet connection.
Comparison of download
speeds vs Upload speeds
When you visit a website with a web browser, you are
downloading information from the Internet.
Many spend more time surfing the Internet and downloading
information, so download speeds are usually more important than upload speeds.
