Computer Memory Basics Although memory is technically any form of electronic storage‚ it is used most often to identify fast‚ temporary forms of storage. If your computer’s CPU had to constantly access the hard drive to retrieve every piece of data it needs‚ it would operate very slowly. When the information is kept in memory‚ the CPU can access it much more quickly. Most forms of memory are intended to store data temporarily. As you can see in the diagram above‚ the CPU accesses memory according

These activities follow a logical flow; however‚ they may not add equal value to the process. * The process ends with a defined output that is the resulting sum of all the activities performed on the input.

A. VOLATILE MEMORY Volatile memory‚ also known as volatile storage‚ is computer memory that requires power to maintain the stored information‚ unlike non-volatile memory which does not require a maintained power supply. It has been less popularly known as term Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge‚ the information eventually fades unless the capacitor

Introduction: An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs usually require an operating system to function. For any computer to function‚ it must have an operating system (OS). A powered computer with no operating system will only display coded text messages only understandable to the computer itself

Communications MIMO Multiple Input‚ Multiple Output (MIMO) technology is a wireless technology that uses multiple transmitters and receivers to transfer more data at the same time. MIMO technology takes advantage of a radio-wave phenomenon called multipath where transmitted information bounces off walls‚ ceilings‚ and other objects‚ reaching the receiving antenna multiple times via different angles and at slightly different times. In radio‚ multiple-input and multiple-output‚ or MIMO (commonly pronounced
