– Access time is less – Power Consumption is less

Cache memories are used in modern, medium and high-speed CPUs to hold temporarily those portions of the contents of main memory which are {believed to be) currently in use. Since instructions and data in cache memories can usually be referenced in 10 to 25 percent of the time required to access

improve the performance of main-memory caching of Web documents.

, to choose which back-end will handle this request. Content-based request distribution can improve locality in the back-ends' main memory caches, increase secondary storage scalability by partitioning the server's database, and provide the ability to employ back-end nodes that are specialized

Cache is fast (1–5 cycle access time) memory sitting between fast registers and slow RAM (10–100 cycles access time)

Cache memories bridge the growing access-time gap between the processor and the main memory. Cache memories use randomisation functions for two purposes: (i) to limit the amount of search when looking up an address in the cache and (ii) to interleave the access stream over multiple independent

The underutilization of disk parallelism and file cache buffers by traditional file systems induces I/O stall time that degrades the performance of modern microprocessor-based systems. In this paper, we present aggressive mechanisms that tailor file system resource management to the needs of I

Scalable shared-memory multiprocessors distribute memory among the processors and use scalable interconnection networks to provide high bandwidth and low latency communication. In addition, memory accesses are cached, buffered, and pipelined to bridge the gap between the slow shared memory
