Peripheral Component Interconnect Express (abbr. as PCIe) is a high-speed, serial expansion bus designed as a replacement for: (Select all that apply)

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?

In order to retain its configuration data, CMOS RAM requires constant supply of electricity which is provided by the:

Which of the answers listed below refers to a source of power for an RTC when the computer is turned off?

What is the name of the most common connector type used for providing power to various hardware components inside the computer case?

A switch, button, or LED on the front/top panel of a computer case has a connector linked to it that must be attached to the appropriate pins on the:

Which of the memory types listed below are designed to store permanent data that cannot be changed? (Select all that apply)

Random Access Memory (RAM) falls into the category of the so-called volatile storage media. It requires a continuous flow of electricity to preserve its contents thus all the data stored in RAM lasts only while the power is on.
