pci express (PCIe)
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.

AGP was the most common before the PCI Express
An ISA slot may be used to add a video card, a network card, or an extra serial port. By the end of the twentieth century, ISA ports were beginning to be replaced by faster PCI and AGP slots. Now, most computers only support PCI and AGP expansion cards.

AGP
The AGP slot was primarily used for graphics cards. These have been phased out by PCI Express slots.

The now obsolete AGP slot was used solely for video. The current slots used for video, the large x16 PCIe connectors, can also be used for general PCIe expansion cards. Sitting in shelf above my head, I still have some PCI and ISA slot video cards: using a general-purpose expansion slot for video is the standard way, and a dedicated graphics expansion slot was a short-term abberation.
AGP (accelerated graphics port) slots are special slots on the motherboard specifically designed to take a graphics card (or video card as they're often called).In recent years AGP has been replaced by the PCI-express standard (or PCI-e as they are often referred to) and thus AGP is generally considered an obsolete format. Even so, AGP hardware is still available, but often at an increased cost & with decreased performance.AGP slots came in a few different speeds. The most common of which was 4X and 8X slots. 8X slots could utilize higher performance 8X cards. A 4X slot is limited to only 4X cards. However, many 8X cards have the capability to be used in a 4X slot, this will usually be denoted in the specifications of the card.
