Expansion Buses and Their Evolution

What is the primary purpose of expansion buses in a computer system?

• To connect additional functions and improve functionality

• To enhance the computer's cooling system

• To increase the size of the motherboard

• To reduce the power consumption of the CPU

Which company created the PCI standard?

• Intel

• NVIDIA

• Microsoft

• AMD

What was a major advantage of PCI devices over older technologies?

• They were more expensive

• They required manual configuration

• They had fewer slots on the motherboard

• They were self-configuring and plug-and-play

What was the primary reason for developing AGP?

• To support faster CPUs

• To address PCI limitations for video cards

• To replace all PCI slots

• To improve audio quality

Which of the following is true about AGP connectors on motherboards?

• They were compatible with PCI Express

• They were limited to one AGP connector per motherboard

• They allowed multiple video cards to work in sync

• They were used for audio enhancements

What is a key feature of PCI Express compared to older bus technologies?

• It uses parallel data communication

• It is not compatible with older PCI slots

• It allows hot swapping of components

• It requires more power than PCI

How does PCI Express improve data transfer efficiency?

• By increasing the size of the connectors

• By using serial data communication

• By using more pins for data transfer

• By reducing the number of lanes

What is the significance of PCI Express being backward compatible?

• It only supports new video cards

• It is incompatible with older PCI devices

• It requires new motherboards for installation

• It allows the use of older PCI slots on the same motherboard

What does AMR stand for?

• Accelerated Media Riser

• Audio Modem Riser

• Analog Modem Riser

• Advanced Memory Riser

Which of the following is true about AMR and CNR?

• They are being phased out in favor of newer technologies

• They are widely used in modern motherboards

• They are used exclusively for video cards

• They are required for all A+ certification exams
