• SIMM—single in-line memory module
• SNMP—Simple Network Management Protocol
• SRAM—static random-access memory

• Cache—Memory with fast access and small capacity used to temporarily store recently accessed
data; found either incorporated into the processor or near it.
• Primary, secondary, tertiary cache—Hierarchical cache memory storage based on the proximity of
the cache to the core of the processor. Primary cache is closest to the processor core and has the
fastest access. Secondary cache has slower access than primary cache, but faster access than tertiary
cache.
• Instruction and data cache—Instructions to the processor and data on which the instructions work.
• Unified cache—Instruction cache and data cache are combined. For example, a processor may have
primary cache with separate instruction and data cache memory, but unified secondary cache.
• Integrated cache—Cache that is built into the processor; sometimes referred to as internal cache.
Cache memory that is physically located outside the processor is not integrated, and is sometimes
referred to as external cache.
