Unlike high-level languages such as Java & C assembly language is much closer to the machine code that actually runs computers; it's used to create programs or modules that are very fast & efficient as well as in hacking exploits & reverse engineering Covering assembly language in the Pentium microprocessor environment this code-intensive guide shows programmers how to create st&-alone assembly language programs as well as how to incorporate assembly language libraries or routines into existing high-level applications Demonstrates how to manipulate data incorporate advanced functions & libraries & maximize application performance Examples use C as a high-level language Linux as the development environment & GNU tools for assembling compiling linking & debugging
