Implicit costs can also be thought of as intangible costs that are not easily accounted for. For example, the time and effort that an owner puts into the maintenance of the company, rather than working on expansion, can be viewed as an implicit cost of running the business.
Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.
The main hardware platform for Android is the ARM (ARMv7 and ARMv8-A architectures), with x86, MIPS and MIPS64, and x86-64 architectures also officially supported in later versions of Android. The unofficial Android-x86 project provided support for the x86 architectures ahead of the official support.
