Why hardware systems may require the installation of the new hardware components?
Well there’s two reasons. One is that software keeps getting more and more complicated. The other is that with the new technologies come new standards that the old pieces don’t conform to and therefore won’t work with. I’ll use graphics cards as an example. In the beginning, the IBM PC/XT and its clones had 8-bit bus slots. This is where the video card (such as it was) would be plugged in. As time went by, 16-bit computing came to the consumer market with the advent of the IBM AT (Advanced Technology) and the Intel 80286 CPU. The 8-bit slots now were 16-bit slots called ISA. Fortunately, 8-bit cards continued to function in ISA slots but the 16-bit ISA cards outperformed them and so nobody wanted the 8-bit cards anymore. The same thing happened when the industry advanced again with the 32-bit Intel 80386DX and SX. The bus architecture changed to the 32-bit EISA which again was backwards-compatible with ISA. Things changed during the time of the 486 when the VESA standard appeared. It d
