COMPUTER ARCHITECTURE
Prepare effectively with this WGU C952 Computer Architecture
Exam, designed to assess essential knowledge of computer
systems and hardware design. It focuses on CPU architecture,
memory systems, instruction sets, and performance
optimization concepts. The exam strengthens analytical thinking
and understanding of how computer components interact.
Suitable for WGU computer science students and IT certification
candidates.
A cache indexed/tagged using physical addresses. || Cache
uses real RAM addresses. ✓ ✓ ...... ANSWER .......
Physically addressed cache
A register that stores return address information when an
exception occurs (ARM concept). || Saves where to return
after handling an exception. ✓ ✓ ...... ANSWER ....... ELR
(exception link register)
, Page 2 of 46
A privileged CPU mode that allows execution of OS-level
instructions and access to protected resources. || "Admin
mode" for the OS. ✓ ✓ ...... ANSWER ....... Supervisor
mode (kernel mode)
A controlled request from a user program for an OS service
(switches to kernel mode). || A program asking the OS to do
something for it. ✓ ✓ ...... ANSWER ....... System call
The process of saving/restoring CPU state to switch
execution between processes/threads. || Switching which
program/thread is running. ✓ ✓ ...... ANSWER .......
Context switch
A control setting/bit that allows exceptions/interrupts to be
recognized. || A switch that lets interrupts/exceptions
happen. ✓ ✓ ...... ANSWER ....... Exception enable
An instruction designed so it can be safely restarted after an
exception/interrupt. || If interrupted, it can be run again
safely. ✓ ✓ ...... ANSWER ....... Re-startable instruction
, Page 3 of 46
A storage system that uses multiple disks to improve
performance and/or reliability. || Using multiple drives
together for speed or safety. ✓ ✓ ...... ANSWER .......
RAID (redundant array of inexpensive disks)
A RAID level that stripes data across disks for performance
with no redundancy. || Faster storage, but no protection—
one drive fails, you lose it all. ✓ ✓ ...... ANSWER .......
RAID 0
Spreading consecutive blocks of data across multiple disks.
|| Split data across drives to go faster. ✓ ✓ ...... ANSWER
....... Striping
A RAID level that mirrors data across disks for redundancy. ||
Same data on two drives for safety. ✓ ✓ ...... ANSWER .......
RAID 1
Duplicating data on multiple disks so one can fail without
data loss. || Keeping an identical copy on another drive. ✓ ✓
...... ANSWER ....... Mirroring
, Page 4 of 46
A RAID design using bit-level striping with dedicated error-
correction disks (rare in practice). || Splits data very finely
and uses extra disks for error checking. ✓ ✓ ...... ANSWER
....... RAID 2
A RAID level using byte-level striping with a dedicated parity
disk. || Data split across drives + one parity drive for
recovery. ✓ ✓ ...... ANSWER ....... RAID 3
The set of disks that collectively store data and redundancy
information for RAID. || The group of drives working together
for protection. ✓ ✓ ...... ANSWER ....... Protection group
A RAID level using block-level striping with a dedicated parity
disk. || Blocks spread across drives + one parity drive. ✓ ✓
...... ANSWER ....... RAID 4
A RAID level using block-level striping with distributed parity
across disks. || Like RAID 4 but parity is spread out (avoids
one parity bottleneck). ✓ ✓ ...... ANSWER ....... RAID 5
