Answer
Threads are parts of the same program that run simultaneously and independently. They enable parallelism within a program, allowing multiple operations to occur at the same time.

Answer
Process management is the mechanism that ensures that each process receives adequate CPU time and access to memory, storage, and other hardware resources. This management prevents processes from interfering with each other and ensures optimal resource allocation.
Step 3
Does the presence of two cores mean that tasks will be processed at double the speed of the CPU, that is, 3.16 GHz? Explain your answer.

Answer
No, each core can process one task at a speed of 1.58 GHz. Although two cores allow for better multitasking, they do not multiply the clock speed. Thus, the processing speed doesn't double.

Answer
Caching prevents slower storage mediums from slowing down the performance of faster processors. It serves to keep the CPU running efficiently by reducing access time to necessary data.
