UNIX treats file directories in the same fashion as files; that is, both are defined by the same type of data structure, called an inode. As with files, directories include a 9-bit protection string. If care is not taken, this can create access control problems. For example, consider a file with protection mode 644 (octal) contained in a directory with protection mode 730. How might the file be compromised in this case?

The perimeter of a triangle is 31 cm. Sides #1 and #2 have equal length, while Side #3 is one centimeter shorter than twice the length of Side #1. Let's determine how long each side is: a. Let x represent the length of Side #1. What essential part of this "let" statement is missing? What is the length of Side #2? Side #3? b. Write a mathematical sentence that states that the perimeter is 31 cm. c. Solve the equation you found in part (b) and determine the length of each side. Be sure to label your answers with the appropriate units.

In priority-based process scheduling, the scheduler only gives control to a particular process if no other process of higher priority is currently in the Ready state. Assume that no other information is used in making the process scheduling decision. Also assume that process priorities are established at process creation time and do not change. In a system operating with such assumptions, why would using Dekker’s solution (see earlier Section) to the mutual exclusion problem be “dangerous”? Explain this by telling what undesired event could occur and how it could occur.
