Apart from specialized industrial use, ISA is all but gone today. Even where present, system manufacturers often shield customers from the term "ISA bus", referring to it instead as the "legacy bus". The PC/104 bus, used in industrial and embedded applications, is a derivative of the ISA bus, utilizing the same signal lines with different connectors. The LPC bus has replaced the ISA bus as the connection to the legacy I/O devices on recent motherboards; while physically quite different, LPC looks just like ISA to software, so that the peculiarities of ISA such as the 16MB DMA limit are likely to stick around for a while.

Old style, obsolete, it let system integraters (just a term describing people wedged in between engineers and users) put in additional specialized hardware that a computer could have allowed technically but too specialized and costly to built-in a computer circuit. It runs at a fixed speed of 8 MHz (or 16 if I was mistaken) 8 or 16 bit, no PnP, no addressing assistance. Local bus back the days of 8086/8088 and Southbridge/legacy bus at the end of its life cycle.
