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.
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.
There are many motherboard sizes, and ATX is simply one of them. Others inlude Mini-ITX, MicroATX, etc.
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
On a motherboard, a CPU socket is where the processors placed, while memory slots are used to insert RAM modules. Additionally, the chipset is an interface between the front side bus and main memory, the flash ROM is used for the system's BIOS, and expansion slots are used for additional cards that can be inserted into the motherboard.
They were known as an "expansion bus". So-called because the expansion cards with edge connectors, plugged directy into the bus board. (Today we would call it a motherboard) There were 3 bus standards: Industry Standard Architecture (ISA) Micro Channel Architecture (MCA) Extended Industry Standard (EISA) I hope that helps.

P1 motherboards are "Socket 7", it should be written on the CPU socket. Also, they only have PCI and ISA expansion slots, AGP and PCI-E Video cards slots never appear on a P1 motherboard. The ram slots may be either 72-pin or 168-pin 'Dimm' slots (on desktop motehrboards, laptop boars could have either of these or 144-pin So-Dimm.
Extension cards. (What else did you think of, decoration?)
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.
