In PCIe architecture, a single full-duplex point-to-point serial communication path consisting of two pairs of wires (where one pair is used for transmitting data and the other pair for receiving data) is known as:

The PCIe labeling (×1, ×4, ×8, ×12, ×16 and ×32) refers to the number of communication links (lanes) available in different versions of the PCIe interface. The base value (x1) relates to the speed of a single lane expressed in MB/s. The multiplier (x) allows for easy calculation of the maximum throughput of the entire interface for a given PCIe variant.

Which of the values listed below refers to the speed of a single-lane (x1) PCIe v1.x link?

A single-lane (x1) PCIe v2.x link offers maximum throughput of up to:

Which of the following answers lists the speed of a single-lane (x1) PCIe v3.x link?

A type of PCI slot for expansion cards installed in laptops characterized by a much smaller form factor when compared to its desktop counterpart is called:

Which of the following integrated circuit types defines the core functionality and capabilities of a motherboard?

In a northbridge/southbridge chipset computer architecture, the function of southbridge is to provide high-speed data links between CPU, RAM, and PCIe graphics controllers.

The term "northbridge" refers to a part of the computer chipset that controls peripheral buses used for connecting lower-speed I/O devices such as hard drives, keyboards, mice, PCI devices, as well as embedded hardware including BIOS, integrated graphics/audio, USB, or Ethernet interfaces.

For CPUs without integrated memory controller, which part of the chipset manages communication between the CPU and memory?
