Busses area standard and common way to move data around a computer. Here are some of the current busses: ISA Industry Standard Architecture EISA-Extended ln(lustry Standard Architecture MCA-Micro Channel Architecture VESA -Video Electronics Standards Association PCI-Peripheral Component Interconnect PCMCIA - Personal Computer Memory Card Industry Association (Also called PC bus) .AGP-Accelerated Graphics Port SCSI-Small Computer Systerns lnt Each of these busses has limitations (speed, length, data width, wire density, etc.), and computer engineers are always looking for better and faster ways to move data Why are there so many standards
