What are the PCI and ISA slots?
pls simplified definition:) tnx What is the exact speed difference between PCI and ISA expansion slots?
Are the slots on the motherboard inside a computer case, used to install expansion cards like sound cards. (E) ISA slots are not used in most modern computers, because they are too slow for modern use and pain to install the cards (drivers, the need to use bridges to a host of basic functions need to configure a lot of things). They are usually black, and "new" ISA EISA (+ other connector more behind the original speed) are often quite long. Old ISA cards work in EISA slots, but usually those working EISA ISA slots. PCI slots are modern, which operate at higher speeds and offer a true "plug and play, making installation much easier maps. Even PCI slots are slowly vanishing, including PCI PCI Express () is supported. EDIT: ISA can not find the correct information about the speed … EISA: about 33 MB / s PCI Max: about 133 MB / s max has also added some information on EISA.
