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

Describe and Evaluate the Working Memory Model - 12 Marks The working memory model is a model which specifically defines the short term memory. It is made up of three sections: the central executive‚ visuo-spacial sketchpad and phonological loop. The central executive is the ’boss’ of the three and this section of the system is the part that makes it possible for humans to multitask. It does this by allocating attention to different parts of the system. These are its slave systems. The capacity

Long-term memory is memory that can last as little as a few days or as long as decades. Life without long term memory is almost impossible if you ask me. Memories play a very important role in your everyday functions and doings. I don’t see how you can function without long term memory because of the amount of things it affects. Memories are critical in having a regular life because you can’t function properly without memories. Life without long term memory is almost impossible in reality because

According to Atkinson and Shiffrin the multi-store memory has 3 distinctive stores; sensory registry‚ short term memory (STM) and long term memory (LTM). Information from the environment enters the sensory memory for 0.5 second‚ if the individual is paying attention this information will enter the STM‚ from there if the information is rehearsed it will be store into the LTM. Duration is how long the memory lasts‚ capacity is how much memory an individual can store‚ encoding is what format it is stores

Chapter 5 Memory Organisation 5.1 Introduction The memory unit is an essential component in any digital computer since it is needed for storing programs and data. Main Memory The memory unit that communicates directly with the CPU is called the main memory. Auxiliary Memory Devices that provide backup storage are called auxiliary memory. The most common auxiliary memory devices used in computer systems are magnetic disks and tapes. The part of the computer system that supervises the flow of

The working memory is supposed to consist of verbal data handling (phonological loop)‚ visual image handling (visuospatial sketchpad)‚ central executive for thinking tasks‚ and other substructures. Presuming the substructures are limited. The achievement in the tasks that rely on the same basic working memory will result in a greater infrusion then the tasks that rely on contrasting working memory components.
