BIOS (basic input/output system)
BIOS is Associate in Nursing integral a part of your laptop all motherboard bios collection comes with it once you bring it home. (In distinction, the package will either be pre-installed by the manufacturer or merchant or put in by the user.)
BIOS may well be a program that’s created accessible to the micro chip on Associate in Nursing erasable programmable memory (EPROM) chip. once you activate your portable computer, the micro chip passes management to the BIOS program, that’s sometimes settled at a similar place on effaceable programmable storage.
HERE IS A GOOD NEWS:
When BIOS boots up (starts up) your portable computer, it initial determines whether or not or not all of the attachments space units in place and operational then it passes the package (or key parts of it) into your computer’s random access memory (RAM) from your magnetic disk or storage device drive.
With BIOS, your package and its applications unit freed from having to understand precise details (such as hardware addresses) relating to the connected input/output devices. once device details modification, exclusively the BIOS program should be changed. generally, this transformation is usually created throughout your system setup. In any case, neither your package or any applications you utilize need to be changed.
Although BIOS is in theory forever the intercessor between the micro chip and I/O device management knowledge and information flow, in some cases, BIOS can harden information to flow on to memory from devices (such as video cards) that require faster information flow to be effective.
