This category treats software-oriented aspects of BIOSs. BIOS is an acronym for: Basic Input/Output System, of personal computers (PC). The BIOS is a chip inside a computer that starts (boots) the computer, runs the Power On Self Test (POST), and holds the buffers for sending information from any software in Random Access Memory (RAM), to any hardware device (via slots and ports) that information must go to. BIOS is also the name of the software that is inside, and runs from, a BIOS chip. The system as a whole is called 'the BIOS'. Making matters less clear, BIOS system and software are also termed 'firmware', to show that it is something that has traits between software and hardware. The PC BIOS was invented by the late programmer, and PC operating system (CP/M) pioneer Gary Kildall.
