Abstract
This documentation consists of 2 section, which clearly explain about the operating system of MAC OS X 10.8 (Mountain Lion) and Computer System Architecture (CSA). In the first section, it refers to some explanation about research, investigate and document areas relating Research, investigate and document areas relating to memory management of MAC OS X 10.8 Mountain Lion. Areas that been discussed in this research documentation to include among other areas, how memory is managed including mechanisms and strategies used, problems faced by these techniques and solutions to overcome them. In section 2, the research documentation mainly talks about CSA refers to Research, investigate and document the usage of registers in a modern computer. Areas to be discussed in this research documentation to include among other areas are reasons for registers, types of registers, register size and organization types of registers.

1.0Introduction
The aim of this documentation is to provide knowledge about to study into workings of computer with both hardware and software, hence the reader will know about the structure and function of modern operating systems and get use to the simple architecture of internal computer. Managing memory usage is one of the most basic requirements of a running application. Despite of acquiring memory as required is easy, there also needs to be at least a way of empty memory that is no longer required. Without such a memory management process, an application will consume more and more memory and eventually swamp the system. In the other way, a processor register can be defined as a temporary high speed storage or small space of storage which available on the Central processor unit (CPU) whose data can be accessed more quickly than storage available elsewhere. (Rahman.k, 2012) Register are make used of accepting data quickly, and transfer data or instructions which being used immediately by the Control Processing Units.

Section 1: Operating System
2.0Memory management of MAC OS X 10.8 (Mountain Lion)

OS X Mountain Lion version 10.8 is the 9th version of these major releases of OS X, Apple Inc.’s PC’s operating system. It was released on July 2012 and brings more than 200 additional new features compare with the MAC OS X Lion, which is the previous 8th version to boost up the

way that human interact. By making use of iCloud, MAC OS X Mountain Lion claims...
