Computer systems : a programmers perspective Computer Systems: A Programmers Perspective Second Edition introduces the important and enduring concepts that underlie computer systems by showing how these ideas affect the correctness performance and utility of application programs. Other systems books written from a builders perspective describe how to implement the hardware or some portion of the system software such as the operating system compiler or network interface.
