Mobiles have different models, screen resolutions, operating systems, network types, hardware configurations, etc. Also, how to test the hardware of the mobile phone itself, is it supporting all the software as it should? Let us have a look at the most popular types of mobile testing for applications and hardware.

The reason is because mobile networks are, as a rule, high latency connections. This is why serving your content from a CDN is so important: even in the internet age, being geographically closer to your customers is advantageous. Armed with this knowledge, we can soon understand why TTFB can often increase so dramatically on mobile.

To secure consumer data, organizations need to make sure that their networks are updated and protected against any malicious activity. The complexity of the software being built and that billions of devices are connected with them through the internet, makes them vulnerable to security threats.

Wasm functions contain native codes compiled at runtime, so they should not be directly migrated as normal JavaScript objects.

You may not think about it often, but the Internet uses a colossal amount of electricity. This, in turn, means that the Internet’s carbon footprint has grown to the point where it may have eclipsed global air travel , and this makes the Internet the largest coal-fired machine on Earth. These include data transfer (i.e.

One example is that Netflix launched it’s streaming service in 2007, just at the point when the cost of streaming a movie over the network (which was dropping fast) became less than the cost of shipping a DVD. You need to be able to innovate fast enough to pivot or reinvent your business model and leverage the change.

After 20 years of neck-in-neck competition, often starting from common code lineages, there just isn't that much left to wring out of the system. In almost every area, Apple's low-quality implementation of features WebKit already supports requires workarounds not necessary for Firefox (Gecko) or Chrome/Edge/Brave/Samsung Internet (Blink).

Of course, there are also times when the problem lies not with your application but with the user’s connection or network configuration.

For example, consider a system that counts unique visitors on some internet site.

As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks.
