Over the last five or more years, there have been a number of different terms swirling around to describe computer hardware. Some of those terms include but aren’t limited to APU, CPU, and GPU.But for people who are confused about acronyms, it’s difficult to understand what a computer really has.Each component has its advantages and disadvantages, so understanding these terms could help in determining which computer would be the best to purchase, or simply aid in improving your practical understanding of computers.CPULet’s start with the easiest of the three â€" the central processing unit, or CPU for short. This chip serves all your essential processing needs. Without a CPU of some sort, a computer simply cannot function. It aids in everything from loading your operating system to executing commands in the command prompt to performing calculations in Excel or similar software.Video games demand much from CPUs, and usually earmark the physics calculations to it. CPUs can come in many different variants, from energy-efficient single-core chips running at a mere 1.0Ghz, to monstrous 8-core powerhouses that can easily achieve 4.0Ghz. Some CPUs also carry with them different technologies, such as Intel’s Hyperthreading, where 4 physical cores can appear to the operating system as 8 virtual cores, getting the most power out of the 4 that you really have.For more detailed information about CPUs and what they do, check out Angela’s article describing exactly what a CPU
