What is Latency?
Meaning of Network Latency
Latency is the time it takes a packet of data to travel to an online server or web server and back.
The lower the latency, the quicker the packet will travel to the server and back. Browsing websites and working on applications that are hosted online will feel more responsive when network latency is low.
Some applications such as voice calls (e.g Skype calling, Whatsapps calls) are sensitive to latency. This means that they need to have a stable internet connection. If the latency is high, conversations may drop off or be constantly interrupted with quiet gaps.
