WGU 952 - Computer ArchitectureAND operator - correct answer A logical bit- by-bit operation with two operands that calculates a 1 only if there is a 1 in both operands. OR operator - correct answer A logical bit-by-bit operation with two operands that calculates a 1 if there is a 1 in either operand. LDUR - correct answer Load into register instruction LDUR X9, [X22,#64] = load value at X22[64] into X9 STUR - correct answer store into register instruction STUR X9, [X22, #64] = ...

WGU C952 - InstructionsInstruction Set - correct answer The vocabulary of commands understood by a given architecture. Stored-program Concept - correct answer The idea that instructions and data of many types can be stored in memory as numbers and thus be easy to change, leading to the stored-program concept. Word - correct answer A natural unit of access in a computer, usually a group of 32 bits. Doubleword - correct answer Another natural unit of access in a computer, usually a group ...

WGU C952scientific notation - correct answer A single digit to the left of the decimal point Normalized - correct answer A number in floating-point notation that has no leading 0s Fraction - correct answer The value, generally between 0 and 1, placed in the fraction field. The fraction is also called the mantissa or significand Overflow (floating point) - correct answer A situation in which a positive exponent becomes too large to fit in the exponent field Exponent - correct answer I...

C952 Computer Architecture Chapter 7Multiprocessor - correct answer A computer system with at least two processors. This computer is in contrast to a uniprocessor, which has one, and is increasingly hard to find today. Task-level parallelism or process-level parallelism: - correct answer Utilizing multiple processors by running independent programs simultaneously. Parallel processing program - correct answer A single program that runs on multiple processors simultaneously. Cluster - cor...
