Like any large transport infrastructure, the Internet is composed of many crossings and junctions, each with its own capacity and speed limit. Sometimes we see slowdowns in traffic. In same way that you should stay in your car while the traffic light lets other drivers, the data sent to your computer to wait while other data passes before reaching you. You logically more likely to experience a slowdown in traffic during the hours when attendance is highest. Similarly, traffic conditions can affect your speed and depend on the geographical situation of the consulting site.
PTCL SPEEDTEST Our bandwidth test measuring tool actually send/receive data between your computer and our distributed network of servers to give you an idea of the speed of your PTCL broadband connection. We calculate the speed of your Internet connection by calculating the time it takes to download a predefined data set.
IMEWE (India-Middle East-Western Europe) submarine cable is an ultra high capacity fiber optic submarine cable system which links India & Europe via Middle East.
