Why the need for PCI Express? As processor clock speeds increase, parallel buses such as PCI become harder to implement. Signal skew and fan-out restrictions restrict the bandwidth achievable on a ...

Standard parallel-bus structures are reaching their performance limits. The only way to increase system bandwidth is to switch to a serial-bus structure. Although serial structures promise enhanced ...

Getting data to a storage medium requires transmission. Parallel transmission has historically been the preferred way to write data to disk. But at current speeds, serial transmission can be faster ...
