WGU C952 Questions and Correct
Answers/ Latest Update / Already Graded
Register File
Ans: A state element that consists of a set of registers that can
be read and written by supplying a register number to be
accessed.
provides 1024 scalar 32-bit registers for up to 64 threads.
machine language
Ans: The language made up of binary-coded instructions that is
used directly by the computer
system software
Ans: The set of programs that enables a computer's hardware
devices and application software to work together; it includes
the operating system and utility programs.
operating system
Ans: (computer science) software that controls the execution
of computer programs and may provide various services

Assembly Language
Ans: Programming language that has the same structure and
set of commands as machine languages but allows
programmers to use symbolic representations of numeric
machine code.
IBM 360/91
Ans: Introduced many new concepts, including dynamic
detection of memory hazards, generalized forwarding, and
reservation stations. Tomasulo's algorithm
The internal organization of the 360/91 shares many features
with the Pentium III and Pentium 4, as well as with several other
microprocessors. One major difference was that there was no
branch prediction in the 360/91 and hence no speculation.
Another major difference was that there was no commit unit, so
once the instructions finished execution, they updated the
registers.
Dynamic Random Access Memory (DRAM)
Ans: Memory built as an integrated circuit; it provides random
access to any location. Access times are 50 nanoseconds and
cost per gigabyte in 2012 was $5 to $10.

Multiple DRAMs are used together to contain the instructions
and data of a program. In contrast to sequential access
memories, such as magnetic tapes, the RAM portion of the term
DRAM means that memory accesses take basically the same
amount of time no matter what portion of the memory is read.
Modern DRAMS consist of rows in each bank
frame buffering
Ans: A portion of RAM containing a bitmap that drives a video
display. It is a memory buffer containing a complete frame of
data.
The image to be represented onscreen is stored in the frame
buffer, and the bit pattern per pixel is re ad out to the graphics
display at the refresh rate. The animation below shows a frame
buffer with a simplified design of just 4 bits per pixel.
Datapath
Ans: The component of the processor that performs arithmetic
operations

Control
Ans: The component of the processor that commands the
datapath, memory, and I/O devices according to the
instructions of the program.
Integrated circuit
Ans: Also called a chip. A device combining dozens to millions
of transistors.
Central processor unit (CPU)
Ans: Also called processor. The active part of the computer,
which contains the datapath and control and which adds
numbers, tests numbers, signals I/O devices to activate, and so
on.
Static random access memory (SRAM)
Ans: Also memory built as an integrated circuit, but faster and
less dense than DRAM.
Instruction set architecture
Ans: Also called architecture. An abstract interface between
the hardware and the lowest-level software that encompasses
