Buses are responsible for transferring data and power throughout our network, and there are two major types of Buses. There are Memory Buses which include the Frontside Bus and the Backside Bus - and these are the Buses that transfer the Static RAM, the SRAM memory that's used for cache that speeds up the processing. And we will discuss Memory Buses in greater detail. Then there are System Buses: System Buses allow our computers to be expanded outside of the box itself. System Buses include the very first System Bus the ISA Bus or Industry Standard Architecture, and we will talk more about the ISA Bus later on in this training. As well as the EISA or Extended Industry Standard Architecture Bus that followed the ISA Bus. The MCA Bus, which was developed by IBM Micro Channel Architecture - this Bus didn't have much of a following, because there were better Buses that came along quite quickly after that, and IBM wanted to be paid royalties to use this Bus. And that strategy didn't quite work the way that IBM thought that it might. We will discuss the MCA Bus, although you are not likely to come in contact with one except for knowing it on the test. VESA Local Bus, which was specifically for a Video Bus, and being a Local Bus, transferred information faster so that video could be improved. PCI, which has come to be the most common Bus, and we will discuss how the PCI Bus works and the advantages of using a PCI, or Peripheral Component Interconnect Bus. AGP, Accelerated Graphics Port Bus, which is now used for a Video Bus and exceeds what the VESA Local Bus was able to do. And then we will discuss some future Buses: the I2O Bus and the IBA Bus. But buses in general are extremely important, not only in workstations but in Servers. Because the different types of Buses we use will determine how much information we can transfer through the Bus. And just like a chain is only as strong as its weakest link, a network is only as fast as its slowest component, or at least a section of a network. A part of a network is only as fast as its slowest component. So we need to use the appropriate Buses in the appropriate places, and that's why we will spend some time discussing Buses. And we will start off by talking about Memory Buses in our next section.
