Answers 2023/2024 GRADED A+
Harvard Architecture correct answers A type of computer system design in which the CPU uses separate
memory interfaces for accessing instructions and data operands
Index correct answers The portion of a memory address that determine where in cache (in what line) a
given main memory address can be mapped
MMU correct answers A hardware device that handles the details of address translation in a system with
virtual memory
Key Register correct answers In an associative memory, this determines the bit positions where matching
is significant
Ease of Use correct answers An architectural quality attribute that reflects how well a given instruction
set architecture supports systems programming
SAM correct answers This memory organization has variable access time and uses a relative address to
locate the next item to be read or written
Dirty Bit correct answers This is used to indicate that a cache line has been modified since it was loaded
from main memory
Benchmark correct answers A program(s) that are used to compare the performance of various
computer systems
Segment Fault correct answers This happens when a location within a variable-sized region of a
program's logical memory is referenced, but it is not currently mapped to a location in physical main
memory
TLB correct answers A type of cache used to hold virtual-to-physical address translation information
Transistor correct answers This technological development was an important factor in moving from "first-
generation" to "second-generation" computers
Valid Bit correct answers 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 correct answers EDVAC
