CACHE Memory INTRODUCTION A CPU cache is a cache used by the central processing unit (CPU) of a computer to reduce the average time to access memory. The cache is a smaller‚ faster memory which stores copies of the data from frequently used main memory locations. Most CPUs have different independent caches‚ including instruction and data caches‚ where the data cache is usually organized as a hierarchy of more cache levels (L1‚ L2 etc.) When the processor needs to read from or write to

potential dangers of nanotechnology‚ should it be used to lightweight sports equipment? Nanotechnology has an array of uses‚ from sunscreen to sporting equipment. Sports equipment has been vastly innovated by the discovery and application of nanotechnology in recent years. The highest end tennis racquets‚ baseball bats and even racing bicycles all use nanotechnology to combine strength and lightness provided by this technology. Some of the bicycles made with nanotechnology are priced at up to $20

let’s dig a little deeper into understanding recovered memories. What are Recovered Memories? A recovered memory is a memory of traumatic event(s) that are now remembered‚ but previously had been forgotten or unknown. So if we think to ourselves for a moment as if this could be true‚ could we all have forgotten memories or memories that are unknown? How would we know if we do? According to dynamic.uoregon.edu‚ “recovered memories can be as simple as forgetting where you left your car keys

Explaining Memories Memory is defined as the faculty by which sense impressions and information are retained in the mind and subsequently recalled. A person’s capacity to remember and the total store of mentally retained impressions and knowledge also formulate memory. (Webster‚ 1992) The study of human memory and in particular the attempts to distinguish between different types of memory have been investigated for the last century. Philosophy‚ psychiatry‚ and psychology have all contributed to
