Includes an improved and expanded review of C++ in a new section. , Coverage of character code is now even more student-friendly. A description of the Unicode character set replaces the treatment of EBCDIC. , New Trace Tags - The Pep/8 assembler and simulator includes a new symbolic trace feature that displays global variables and the run-time stack in real time as the student single steps through the program.  The documentation advantage of trace tags is so great that the text now describes the trace tag syntax and includes trace tags in every assembly language program in the text and solutions manual. , Includes new Programming Problems! , Improved RAID coverage - Includes more extensive coverage of RAID disk systems. The difference between RAID levels 01 and 10 is expanded with new figures and a new quantitative analysis exercise. , Improved MIPS coverage - The MIPS coverage is expanded and includes a systematic comparison of Pep/8 as a CISC architecture versus MIPS as a RISC architecture.
