What is the purpose of a CPU cache?
To replace the main memory entirely.
The purpose of a CPU cache is to speed up data access for the CPU by storing frequently used data and instructions.
To increase the CPU's power consumption.
To store all data permanently for the CPU.
What is the difference between SSD and HDD?
SSDs use mechanical parts while HDDs are solid-state drives.
SSDs are cheaper and have larger storage capacities than HDDs.
SSDs are faster and more durable than HDDs, which are slower and use mechanical parts.
HDDs are faster and more reliable than SSDs.
What is a mesh network topology?
