PPT-Computer Memory Introduction

Random Access Memory or RAM is the temporary storage in a computer system This means that once a computer is turned off everything stored in it is lost When an application is opened it is copied into . 1 Introduction In computer networks packet arrivals and service are modeled as a stochastic process in which events occur at times t For instance in the 64257gure below t can be interpreted as the packet arrival times or the service completion tim to Programming.

Hardware Concepts. Data are represented in the computer memory in bits. That is 0s and 1s. . 8bits make up a byte.. Data entered into the computer have to be converted into the machine readable form.. In a better . way of handling complex types of data ( long streams of binary digits). Higher number systems are used in computing to reduce the streams of binary into manageable form, thus helps to improve the processing speed and optimize . of computer science and the art of . programming.
