The original IBM compatible parts used an 8-bit ISA slot. After that, they moved to a 16-bit ISA slot. There were other things like a VESA slot that didn't last for long. Then there were PCI slots (not express), and AGP was a faster video card slot standard. Then PCI-express replaced both PCI and AGP.

PCI is available in both 32-bit and 64-bit versions.
The ISA slot started as 8-bit, and then evolved to 16-bits.
ISA is the precursor to PCI. Standing for "Industry Standard Architecture" It was common from the early 1980s to the mid 1990s. ISA was a typically inelegant solution for the time, and required one to know exactly what one was doing- PnP was rare, even for so called "ISA PnP" peripherals. In the end, the combination of flexibility, ease of use, and greater capability allowed PCI to supersede ISA.
No. The first expansion slots on IBM PCs (and compatibles) had only an 8-bit data path, and ran at 8 Mhz.
The 8-bit slot had 62 pins. The 16-bit slot had an additional 36 pins.
IBM knows, It was 8 bit PC
Yes.
Because IBM wanted to build a computer with an 8-bit data bus. The 8086 and 8088 are the same processor, with the 8086 running on a 16-bit data bus, and the 8088 running on an 8-bit data bus. This allowed IBM to make the most use of older designs that supported 8-bit data buses, such as the 8080, the 8085, and the Z80.
A "bit" is short for binary digit.
