CPSC Exam 1 UPDATED Study Guide
QUESTIONS AND CORRECT ANSWERS
CPU/processor - CORRECT ANSWER Central Processing Unit. carries out all the
instructions from the software and program
RAM/main memory - CORRECT ANSWER main memory. where the data is stored.
where programs are kept when the processor is actually using them. volatile, when computer
shuts down everything is lost.
Hard Drive - CORRECT ANSWER permanent storeage/ known as the disk
Von Neumann Architecture - CORRECT ANSWER CPU, MAIN MEMORY, HARD
DRIVE, DISK
BUS - CORRECT ANSWER a communication system that transfers data between
components within the computer
Von Neumann Cycle - CORRECT ANSWER Fetch, fetch instructions from
memory/disk
Decode, examines instructions and gets operands from memory/disk
Execute, once computer has instructions and operands it can execute the operation
Store Result, processor will store result in memory until power turns off, then will be stored
in disk
repeat
Von Neumann Bottleneck - CORRECT ANSWER the processor cannot process as fast
as one can ask, since the bus can't transfer information as fast there is a limited transfer rate
Compiled language - CORRECT ANSWER (ex: C++) uses a compiler than converts
source code into binary operations. Faster than interpreted language but not portable.
