Preface
Related Documentation
• EPROM—erasable programmable read-only memory
• FRU—field-replaceable unit (router components that do not require replacement by a
Cisco-certified service provider)
• GBIC—Gigabit Interface Converter
• Gbps—gigabits per second
• Instruction and data cache—Instructions to the processor and data on which the instructions work.
• 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.
• MB—megabyte
• NVRAM—nonvolatile random-access memory
• OIR—online insertion and removal
• PCI—Peripheral Component Interconnect
• PCMCIA—Personal Computer Memory Card International Association
• 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.
• RFI—radio frequency interference
• RISC—reduced instruction set computing
• SDRAM—synchronous dynamic random-access memory
• SIMM—single in-line memory module
• SNMP—Simple Network Management Protocol
• SRAM—static random-access memory
• TFTP—Trivial File Transfer Protocol
• 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.
