With some unique advantages like low latency and faster speed, 5G aims to give birth to a new era of mobile application development with some innovations. With the increase in speed and less latency, there are a lot of possibilities that can be explored in the field of the internet of things (IOT) and smart devices.

Fundamentally, internet traffic can be broadly categorized into static and dynamic content. Yes, it’s a single file, but that’s not how it’s stored on the internet. This type of traffic originates directly from the server, making it more challenging to handle due to latency and server load considerations; it’s hard but not impossible.
