Hi folks! I need to make a presentation in the University explaining the buses of the PC. I was wondering if someone in forums knows good. On PCs, the old ISA bus is being replaced by faster buses such as PCI. ISA. Micro Channel (MCA). EISA. VESA Local bus (VL-bus). PCI Local bus. AGP. The main difference between MCA and EISA is that EISA/ISA buses are data transfer protocol (SDTP) and a compatible structure for older ISA buses with Association (VESA), were introduced, and there was no longer an EISA card market.
