Memory Management Memory management can become very complex in modern day computers as with the requirements for the management of the memory. There are four categories that must be satisfied within memory management which are address mapping and relocation‚ protection and sharing‚ application organization‚ and two-level memory organization. Had one of these categories not been satisfied through memory management‚ then it is a failure and could cause major problems in terms of an operating system

Primary memory. There are two kinds of computer memory: primary and secondary. Primary memory is accessible directly by the processing unit. RAM is an example of primary memory. As soon as the computer is switched off the contents of the primary memory is lost. You can store and retrieve data much faster with primary memory compared to secondary memory. Primary memory is more expensive than secondary memory. Because of this the size of primary memory is less than that of secondary memory. Computer

In a system using virtual memory‚ the physical memory is divided into equally-sized pages. The memory addressed by a process is also divided into logical pages of the

Introduction to Cache Memory Cache memory is a random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data‚ it looks first in the cache memory and if it finds the data from a previous reading of data‚ it does not have to do the more time-consuming reading of data from larger memory. Cache memory is sometimes described in levels of closeness and accessibility to the microprocessor. An L1 cache is on the same
