🔥 ram → RAM is a specific form of system memory; understanding memory hierarchy, allocation, locality, and memory models is required to explain RAM’s role, behavior, and performance.

🔥 nonvolatile memory → Nonvolatile memory extends the general concept of memory by retaining data without power while preserving standard addressing and access semantics for persistent media.

🔥 volatile memory → Understanding general memory concepts—hierarchy (caches to RAM), allocation, locality, and memory models—is required to correctly define, characterize, and use volatile memory, which loses state without power.

🔥 main memory → Main memory specializes the general concept of memory to volatile, byte-addressable RAM used by running programs, defining its position in the hierarchy (between CPU caches and storage) and its latency/bandwidth/capacity constraints that shape allocation and access patterns.

🔥 cache memory → Cache memory is a specialized high-speed tier that stores copies of data from main memory and depends on memory addressing, coherence, and locality to reduce effective access latency.

🔥 rom → ROM is a specific, non-volatile form of memory; understanding memory hierarchy, addressing, and access semantics is required to grasp ROM’s read-only behavior, mapping, latency, and role in firmware storage.
