Which statements are true of processor cache? (Select two)

The statement regarding L3 cache being shared between all cores is accurate. In modern multi-core processors, the Level 3 (L3) cache serves as a larger cache space that is accessible by all cores. This shared cache helps improve performance by allowing cores to access frequently used data, reducing latency and improving bandwidth efficiency. By sharing the L3 cache, cores can efficiently collaborate on tasks and reduce redundant data storage, which is beneficial in multi-threaded applications and overall system performance.

L1 cache, in contrast, is typically unique to each processor core and is designed for quick access to data that the core is currently processing. L1 cache is smaller and faster than L2 or L3 caches, which allows for high-speed data retrieval. Given its design, L1 cache does not have the largest capacity; in fact, processor caches are structured to have increasing capacities from L1 through L3, indicating a hierarchy where L1 is the smallest and fastest, while L3 is larger but comparatively slower. This hierarchical organization optimizes performance by balancing speed and cost.
