List and describe the components found in a Pentium processor.
What will be an ideal response?
An input/output (I/O) unit manages data and instructions entering and leaving the processor. A control unit manages all activities inside the processor itself. One or more arithmetic logic units (ALUs) do all logical comparisons and calculations inside the processor. Registers, which are small holding areas on the processor chip, work much like RAM does outside the processor to hold counters, data, instructions, and addresses that the ALU is currently processing. Internal memory caches (L1, L2, and possibly L3) hold data and instructions waiting to be processed by the ALU. Buses inside the processor connect components within the processor housing.

Answer the following statement true (T) or false (F)
A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly
restricted in that it always operates on precisely the range 1 to 10. List different ways that this program can be sabotaged so that during execution it computes a different sum, for example, 3 to 20. What will be an ideal response?
