    What is Internet?

    Internet is a large network of computers connected with each other through wires or wireless connections. It is a network of computers which transfer data between each other for the purpose of information sharing and resource sharing, communication, and data sharing. Hundreds of thousands of computers can be connected to a single computer at one time through internet and can send or receive data between each other. Example includes websites which get millions of visitors and those websites run on server computers which are permanently connected to internet 24/7 and can transfer GB's of bandwidth per second.

    What is Internet Speed Test?

    Internet speed test is a measurement of a data transfer rate per second of your internet connection. This data transfer rate is calculated by first finding the nearest internet connected server from your computer, and then transferring the MBs of data between both computers. The speed at which this file transfers between both computers is the actual internet connection speed and this speed varies due to various factors involved in data transfer.

    What is CenturyLink Speed Test Service?

    CenturyLink speed test is performed by performing various speed tests using your CenturyLink internet connection. This happens when our speed test service sends a chunks of bytes to CenturyLink's nearest server. Firstly, we perform a download test in which chunks of bytes are downloaded from remote server to your computer and the transfer rate of downloading that file is measured, this is called Download speed test. Next is CenturyLink upload speed test which is performed by uploading random chunks of bytes from your computer to the nearest server and the transfer rate is checked accordingly. When both of the tests are performed, the results are calculated and shown.

    What Factors affects the internet speed?

    Various factors affects the internet speed of your internet connection, some of those are latency, jitter, download speed, upload speed, weather, distance from connected computer, and more. The latency is the response time of a server that is the time in which first byte of data is received on each request. Download speed is the rate at which a file downloads to your computer, Upload speed is the rate at which a file uploads to any server from your computer. The weather conditions effects the internet in a way that if your internet connection is wireless, it will be effected by extreme weather because the signals gets weaker due to storms and rains or too much of a heat. The wired internet connection also sometimes gets effected by weather in those circumstances where the cable is damaged and or the loose connectors between your nearest DB and your home/office.
