What are the types of cache in the processor and what do they do?

• L1- Cache memory integrated into the processor which is the fastest type of memory
• L2- Cache in the processor packaging that's not part of the CPU (on-die cache)
• L3- Cache that's usually found in the more powerful processors and can be located in the CPU or on the motherboard/ When there is no info in the cache the processor goes to the motherboard RAM.

What is the difference between a CPU and a GPU? How do they process information differently?

CPU stands for Central Processing Unit while GPU stands for Graphics Processing Unit. CPUs contain multiple core processors, while GPUs contain hundreds of smaller core processors. Those GPUs are called GPGPUs (General Processing GPUs). Integrated GPUs can have their own cache memory or share with the CPU.

What are three different things used to cool processors?

• Fans can be attached to the processor
• Heat sinking is where a block of metal, usually aluminum or copper attaches to the top of the processor or other motherboard components. The heat from the processor is then transferred to the heat sink and then blown away by the airflow throughout the computer
• Passive cooling involves no fans so a heat sink that does not have a fan attached is known as a passive heat sink
