IA stands for Industrial Standard Architecture and is used for transfer data bits

With the exception of some various expensive industrial motherboards, you will not find any ISA slots on a motherboard. In order to be certified for Windows 2000 and later, Microsoft required that manufacturers remove ISA slots from their boards.
PCI, AGP, and ISA are types of expansion bus slots. These slots allow you to attach internal peripherals such as video cards, hard drive controllers, modems, tuner cards, and other things.
If you look at your manual, you will see there are no ISA slots on this board. 2- pci-e 16x 2- pci-e x1 1- pci
Extension cards. (What else did you think of, decoration?)
PC Card slots originally used a 16-bit ISA bus
According to my A+ book a CPU in a AT mobo will sit towards the front of the board and in front of the ISA slots. On an ATX mobo it will sit towards the back near the fan and to the side of the ISA slots.
ISA slots are available in both 8-bit and 16-bit form.
PCI = 533 MB/s max. ISA = 8 MB/s max. So 525MB/s faster.
Many devices were historically available for ISA slots. Modems, sound cards, video cards, hard disk controllers, terminal emulators, and network interfaces are all examples of devices that were available for the ISA slot.
