Detailed explanation-3: -(PCIe) was developed to replace PCI, PCI-X, and AGP. Instead of a shared bus, each PCIe slot links to a switch that prioritizes and routes data through a point-to-point dedicated connection and provides a serial, full-duplex method of transmission. PCIe uses several different connection types.

Detailed explanation-4: -NVM Express devices are chiefly available in the form of standard-sized PCI Express expansion cards and as 2.5-inch form-factor devices that provide a four-lane PCI Express interface through the U. 2 connector (formerly known as SFF-8639). Storage devices using SATA Express and the M.

Detailed explanation-5: -Serial ports transmit one bit of data at a time.
