Most of the computers on Earth have Intel Inside®, right?
Nope. Most mobile computers, such as smartphones and tablets, use some other processor chip (the CPU). The most popular of these is called the ARM. It's been used in computers since 1985 and its design has been kept up-to-date ever since.
All Apple iPhones and iPads use some version of the ARM processor, which Apple calls the A5, A6, and A7. You'll find the ARM used in most Android devices, in Chromebooks, and many (or most) Microsoft Windows 8 mobile devices. It's the processor used in the popular Raspberry Pi computer.
The photo below is of Sophie Wilson, the designer of the first ARM chip and many later versions. Sophie is also notable because she used to be Roger Wilson before 1994.
