The 'PCIe' bus standard uses what kind of connection topology?
The 'PCIe' bus standard uses what kind of connection topology?
a)
A shared parallel bus where all devices compete for access.b)
A point-to-point serial connection with dedicated 'lanes' for each device.c)
A ring topology where data circulates through all devices.d)
A wireless connection.Explanation
Unlike the older PCI bus, which was a shared parallel pathway, PCI Express (PCIe) provides each device with its own dedicated serial link to the system. These links are made up of one or more 'lanes' (e.g., x1, x4, x8, x16), providing scalable, high-speed, full-duplex communication without bus contention.Related questions
