Petrie’s Electronics Case Questions Solutions (15 Points) 2. Again, review the DFDs you developed for the Petrie’s Electronics case (or those given to you by your instructor). Use these DFDs to identify the attributes of each of the six entities listed in this case plus any additional entities identified in your answer to Question 1. Write an unambiguous definition for each attribute. Then, redraw Figure 7-1 by placing the six (and additional) entities in this case on the diagram along with their associated attributes.
A program in machine code for an Intel x86-based PC will not run on an IBM mainframe computer, and vice versa. Assembly language is a symbolic representation of machine code, which allows programmers to write programs in machine code without having to deal with the long binary strings. For example, the machine code for an instruction that adds two numbers might be 01101110, but in assembly language, this can be represented by the symbol ADD. A simple assembler program translates this symbolic language directly into machine code. Because
