Why does a higher CPU clock speed generally improve performance?

• It increases the amount of cache memory

• It allows more instructions to be executed per second

• It expands the RAM capacity

• It completely eliminates the need for multitasking

Which of these RAM characteristics contributes most directly to computer speed?

• Color of the RAM

• Number of RAM sticks

• Size and retrieval speed of RAM

• Brand name

What is the main reason a faster hard disk improves system performance?

• It changes the desktop wallpaper faster

• It increases the data read/write speed

• It uses more power

• It doesn't need defragmentation

How does having more free space on a traditional HDD help performance?

• It improves cooling

• It reduces file fragmentation and leaves room for optimized data placement

• It decreases the need for antivirus scans

• It increases CPU clock speed automatically

Why does running multiple applications at once slow down a computer?

• It blocks the internet connection

• It consumes shared memory and CPU time

• It defragments the hard drive

• It upgrades the hardware without permission

How does a more powerful graphics card improve performance?

• By increasing hard disk capacity

• By processing visuals faster and offloading work from the CPU

• By reducing RAM size

• By defragmenting the SSD

What effect does defragmenting a traditional HDD most directly have on system performance?

• It increases visual effects

• It rearranges data to reduce read/write delays

• It deletes temporary files

• It upgrades the RAM

Why should SSDs not be defragmented?

• They don't hold any files

• They access data rapidly and unnecessary writes shorten their lifespan

• They run on batteries

• They are inherently fragmented

What is the role of cache memory in improving performance?

• Caching stores entire operating systems

• Cache stores frequently used data closer to the CPU for faster access

• Cache expands storage capacity

• Cache compresses files automatically

How does increasing the width of the data bus affect performance?

• It slows down the system

• It allows more bits to be transferred simultaneously, speeding data flow

• It changes the OS layout

• It boosts the GPU clock speed
