Mainboard-Labled

Have a look at the board below. The locations for various components are written on the photo below. Note that although this is an oder mainboard, teh components haven't changed much since this photo was taken. ISA bus slots (8-bit) are now uncommon, and rarely if ever used. The white PCI card slots (32 bit) are currently the norm as is the brown AGP slot (32 or 64 bit video slot). The CPU slot is a temporary aberration used by the early P4 and AMD chipsets.
