Acoustic Cryptanalysis Attempts on CPU and Keyboard

ABSTRACT
Acoustic sound is a natural phenomenon which can be emitted from interactions among physical objects or materials with its specific acoustic signature in frequency, amplitude and signal pattern or spectra. The emission occurs when a small surface displacement of a material is produced due to a rapid release of energy in a material, or on its surface. Acoustic sound which has specific spectra signature could be a powerful tool to reveal important information from the object bein ....etc

ABSTRACT:
Traditional processor scheduling mechanism in operating systems is rigid. They control the sharing of machine’s CPU resources among threads using one fixed scheduling scheme., typically based on priority. Sometimes variants on basic scheduling algorithms are provided But these various techniques are hard to implement and cannot be easily fulfill needs of individual applications.
This paper represents novel processor scheduling framework based on generalized notion of priority inheritance. In this frame ....etc

CPU SCHEDULING
Introduction
 Multiprogramming A number of programs can be in memory at the same time. Allows overlap of CPU and I/O.
 Jobs (batch) are programs that run without user interaction.
 User (time shared) are programs that may have user interaction.
 Process is the common name for both.
 CPU - I/O burst cycle Characterizes process execution, which alternates, between CPU and I/O activity. CPU times are generally much shorter than I/O time ....etc

CPU(Main Processor)
 The main component of any motherboard is the main processor chip
 It controls all the inner functions of the system.
 The Central Processing Unit(CPU)functions as the brain of every PC.
 CPU is responsible for the overall working of all components of the computer. It consists of two parts ALU & CU.
 The Arithmetic Logic Unit performs arithmatic operations and conducts the comparison of information for logical decisions.
 The Control Unit is responsible for ....etc
