The kernel is the central part of the operating system, which is like an intermediary between the software part of the smartphone and all the hardware. Any action performed by the user is processed and passed through the kernel. Let’s look at a simple example to illustrate. Suppose you pressed the power button. The system is automatically told that you want to activate the screen. This whole process goes directly through the core of the device.
By the way, many people think that only smartphones have a kernel. Almost all devices with a processor have one. You may have noticed that the smartphone’s specifications often indicate the number of cores of the processor. Most often, modern phones are equipped with an 8-core chipset. And in general, the more cores, the better.
As some studies show, there is no significant difference between the 8-core and 4-core processors. The catch is that an 8-core chip consists of two 4-core processors, between which all tasks are evenly distributed. If simple actions are performed – launching the camera or opening settings, the processor with the lowest clock speed works. But when the game starts, the whole load goes to the more productive chip.
By the way, to know the number and architecture of cores, we use the application AIDA 64. Open the program and go to “CPU”. Here we pay attention to the line “Core architecture”. We can see the name of the architecture, the number of cores, and the clock frequency of each of them.
