"Second generation" bus systems like NuBus addressed some of these problems. They about afar the computer into two "worlds", the CPU and anamnesis on one side, and the assorted accessories on the other. A bus ambassador accustomed abstracts from the CPU ancillary to be confused to the peripherals side, appropriately alive the communications agreement accountability from the CPU itself. This accustomed the CPU and anamnesis ancillary to advance alone from the accessory bus, or aloof "bus". Accessories on the bus could allocution to anniversary added with no CPU intervention. This led to abundant added good "real world" performance, but additionally appropriate the cards to be abundant added complex. These buses additionally generally addressed acceleration issues by actuality "bigger" in agreement of the admeasurement of the abstracts path, affective from 8-bit alongside buses in the aboriginal generation, to 16 or 32-bit in the second, as able-bodied as abacuscomputer application bureaucracy (now standardised as Plug-n-play) to supplant or alter the jumpers.
However these newer systems aggregate one affection with their beforehand cousins, in that anybody on the bus had to allocution at the aforementioned speed. While the CPU was now abandoned and could access acceleration after fear, CPUs and anamnesis connected to access in acceleration abundant faster than the buses they talked to. The aftereffect was that the bus speeds were now actual abundant slower than what a avant-garde arrangement needed, and the machines were larboard fatigued for data. A decidedly accepted archetype of this botheration was that video cards bound outran alike the newer bus systems like PCI, and computers began to accommodate AGP aloof to drive the video card. By 2004 AGP was outgrown afresh by high-end video cards and added peripherals and has been replaced by the fresh PCI Express bus.
An accretion cardinal of alien accessories started employing their own bus systems as well. When deejay drives were aboriginal introduced, they would be added to the apparatus with a agenda acquainted into the bus, which is why computers accept so abounding slots on the bus. But through the 1980s and 1990s, fresh systems like SCSI and IDE were alien to serve this need, abrogation best slots in avant-garde systems empty. Today there are acceptable to be about bristles altered buses in the archetypal machine, acknowledging assorted devices.
