Understanding PCI Express Features

The video tutorial provides an overview of motherboard components and their communication paths, focusing on PCI and PCI Express technologies. It explains the differences between parallel and serial communication, the specifications of PCI cards, and how to install them. The tutorial also covers the transition from PCI to PCI Express, highlighting the advantages of serial communication and the use of lanes for data transfer.

What is the primary function of a bus on a motherboard?

• To store data permanently

• To provide a communication path between components

• To power the components

• To cool down the CPU

Which of the following is true about PCI slots?

• They do not require a central controller

• They are commonly found in the latest computers

• They are used for serial communication

• They support both 32-bit and 64-bit buses

What distinguishes a 64-bit PCI slot from a 32-bit PCI slot?

• The 64-bit slot is smaller

• The 64-bit slot supports only 3.3 volts

• The 64-bit slot has more contacts

• The 64-bit slot is used for serial communication

What should you check before installing a PCI card?

• The color of the card

• The weight of the card

• The voltage compatibility and slot alignment

• The brand of the card

What is a key difference between PCI and PCI Express?

• PCI Express uses serial communication

• PCI Express does not use lanes

• PCI Express is older than PCI

• PCI Express uses parallel communication

How does PCI Express improve data transfer compared to PCI?

• By reducing the number of contacts

• By using multiple lanes for increased bandwidth

• By using a single lane for all data

• By using a parallel bus

What does the 'x' in PCI Express lane designations (e.g., x1, x4) represent?

• The number of lanes

• The voltage level

• The card size

• The power consumption

What is the purpose of the hook on a PCI Express card?

• To connect to the CPU

• To provide additional power

• To lock the card into the slot

• To increase data transfer speed

What should you do if a PCI Express card does not fit into the slot?

• Use a different card

• Remove the hook

• Check the alignment and settings

• Force it into the slot

Which of the following is a feature of PCI Express cards?

• They have a locking mechanism

• They require no alignment

• They use parallel communication

• They are incompatible with older motherboards
