Chassis intrusion detection is an option that can be enabled/disabled in the BIOS setup utility (if a BIOS comes equipped with this feature). Coupled with a hardware sensor mounted inside the computer case, this functionality can be used to check if the case was opened and display a notification alert during next boot.
True
A standardized specification of a motherboard (including its dimensions, supported power supply types, and layout of components) is known as the motherboard’s:
Form factor
Which of the following terms are used to describe a motherboard's size and purpose? Micro-ATX PCI-X ITX ATX Mini-ITX
Micro-ATX
ITX
ATX
Mini-ITX
What is the most common motherboard type used in desktop PCs?
ATX
Which of the answers listed below refers to a VIA-proprietary low-power consumption SFF type motherboard known for industrial and embedded PC applications?
Mini-ITX
Low Profile Extended (LPX) and New Low profile eXtended (NLX) are motherboard form factors known for the usage of a riser card (daughterboard) inserted into a slot near the edge of the board. The main advantage of this type of design is that expansion cards that plug into a riser card on the LPX/NLX motherboard are parallel with the board which saves space and allows for a smaller system case. (True or False)
True
Which of the following statements are true? (Select 3 answers)
A parallel bus transmits data across multiple wires
In computer architecture, the term “bus” describes a system of communication paths used to connect computer components and transfer data between them
A parallel bus transmits data sequentially one bit at a time over a single communication channel
A serial bus transmits data across multiple wires
A serial bus transmits data sequentially one bit at a time over a single communication channel
A parallel bus transmits data across multiple wires
In computer architecture, the term “bus” describes a system of communication paths used to connect computer components and transfer data between them
A serial bus transmits data sequentially one bit at a time over a single communication channel
Peripheral Component Interconnect (PCI) is an example of a parallel expansion bus (and a corresponding slot type) used for attaching hardware devices (in the form of an integrated circuit or expansion card) to the motherboard inside the computer case. (True or False)
True
What are the characteristic features of conventional PCI?
32-bit bus width
64-bit bus width
Parallel interface
Maximum throughput of up to 533 MB/s
The Peripheral Component Interconnect eXtended (PCI-X) is an advanced version of PCI which:
Doubles the bandwidth of PCI
Provides much faster data transfer rates in comparison to PCI
Offers backward compatibility with PCI devices
Didn’t get much of a market success due to the development and widespread adoption of the PCIe standard
Was intended for devices with higher bandwidth requirements such as servers and high-end workstations
Which of the following answers describe(s) the feature(s) of the PCI-X standard?
Parallel interface
Maximum throughput of up to 1064 MB/s
64-bit bus width
Which of the answers listed below refers to a standard that relies on serial communication?
PCIe
Motherboard slots that enable installation of dedicated graphics controllers include:
AGP
PCIe
Peripheral Component Interconnect Express (abbr. as PCIe) is a high-speed, serial expansion bus designed as a replacement for:
PCI
PCI-X
AGP
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:
Lane
