CPEN 4700 - Final Exam Questions And
100% Correct Answers
Harvard Architecture - ANSWER A design for a computer system in which the CPU uses
separate memory interfaces for accessing instructions and data operands
Index - ANSWER The part of memory address that determines where in cache (in which
line) a given main memory address can be mapped
MMU - ANSWER A hardware device that performs the details of address translation in a
system with virtual memory
Key Register - ANSWER In an associative memory this determines the bit positions
where matching is significant
Ease of Use - ANSWER An architectural quality attribute that reflects how well a given
instruction set architecture supports systems programming
SAM - ANSWER This memory organization has variable access time and uses a relative
address to locate the next item to be read or written
Dirty Bit The dirty bit indicates whether a cache line has been modified since it was
loaded from main memory.
Benchmark A program(s) that are used to compare the performance of various
computer systems
Segment Fault - ANSWER This is what happens when a program refers to a location in
variable-sized region of its logical memory, but that location is not currently mapped to a
, location in physical main memory
TLB - ANSWER A cache-like structure to store virtual-to-physical address translation
information
Transistor - ANSWER This was the technology that was primarily responsible for the
shift from "first-generation" to "second-generation" computers
Valid Bit - ANSWER This is used to indicate that a cache line has been properly
initialized from main memory
This early computer used the stored program concept; its logical design was described
in a 1945 report written by John von Neumann - ANSWER EDVAC
A computer that used - or will use - an 8-bit microprocessor as its main CPU would most
likely have a manufacture date of: - ANSWER 1981
A computer using, or to be using, ferrite core technology in its main memory system
would most likely have a manufacture date of: - ANSWER 1965
Which of the following is NOT one of the computer architectural quality factors
described in our textbook? - ANSWER Synchronicity
User-Friendliness
An early computer designed by the researchers at Harvard avoided the "von Neumann
bottleneck" that was due to which of the following shortcomings of the Princeton
machine? - ANSWER Placing code and data in the same memory
An early computer designed by the researchers at Harvard avoided the "vonNeumann
bottleneck" using which of these approaches? - ANSWER Separate memories for
instructions and data
