MEMORY OF COMPUTER: DETAILED EXPLANATION INTRODUCTION MEMORY IN A COMPUTER IS THE MOST ESSENTIAL COMPONENT THAT STORES DATA, INSTRUCTIONS, AND INFORMATION TEMPORARILY OR PERMANENTLY. IT ACTS AS A BRIDGE BETWEEN THE CENTRAL PROCESSING UNIT (CPU) AND THE STORAGE DEVICES, ENSURING SMOOTH DATA PROCESSING AND RETRIEVAL. WITHOUT MEMORY, A COMPUTER CANNOT PERFORM ANY OPERATION. COMPUTER MEMORY IS BROADLY CATEGORIZED BASED ON ACCESS TIME, CAPACITY, COST, AND VOLATILITY . IT DETERMINES THE PERFORMANCE AND EFFICIENCY OF THE ENTIRE SYSTEM. TYPES OF COMPUTER MEMORY COMPUTER MEMORY IS MAINLY DIVIDED INTO PRIMARY MEMORY AND SECONDARY MEMORY , AND ALSO INCLUDES CACHE MEMORY AND VIRTUAL MEMORY AS SPECIAL TYPES. 1. PRIMARY MEMORY (MAIN MEMORY) PRIMARY MEMORY IS DIRECTLY ACCESSIBLE BY THE CPU. IT IS FAST BUT LIMITED IN SIZE AND VOLATILE IN NATURE, MEANING DATA IS LOST WHEN POWER IS TURNED OFF. CHARACTERISTICS: HIGH SPEED LIMITED STORAGE CAPACITY VOLATILE (T...
HOW DO COMPUTER UNDERSTAND THE BINARY LOGIC? . I AM GOING TO WRITE ABOUT BINARY LOGIC, THAT MOST OF THE COMPUTER MANUFACTURERS AND DEVELOPERS USE. BINARY LOGIC DEALS WITH VARIABLES THAT TAKE ON TWO DISCRETE VALUES AND WITH OPERATIONS THAT ASSUME LOGICAL MEANING. THE TWO VALUES THE VARIABLES TAKE MAY BE CALLED BY DIFFERENT NAMES (E.G. TRUE AND FALSE, YES AND NO, ETC.), BUT FOR OUR PURPOSE IT IS CONVENIENT TO THINK IN TERMS OF BITS AND ASSIGN THE VALUES OF 1 AND 0. BINARY LOGIC IS USED TO DESCRIBE, IN A MATHEMATICAL WAY, THE MANIPULATION AND PROCESSING OF BINARY INFORMATION. IT IS PARTICULARLY SUITED FOR THE ANALYSIS AND DESIGN OF DIGITAL SYSTEMS. FOR EXAMPLE, THE DIGITAL LOGICAL CIRCUITS OF MANY CIRCUITS THAT PERFORM BINARY ARITHMETIC ARE CIRCUITS WHOSE BEHAVIOR IS MOST CONVENIENTLY EXPRESSED BY MEANS OF BINARY VARIABLES AND LOGICAL OPERATIONS. ...
