ECEN 324 Test 1 questions and
answers rated A+
Amdahl's Law Equation - correct answer ✔✔ Speedup = 1 / ((1-α) + α/k)
Speedup = T_old/T_new
T/F: A system spends a lot of time moving information from one place to another - correct
answer ✔✔ True
Choose all of the following that are text files:
Source program, Assembly program, Relocatable object program, Executable object program -
correct answer ✔✔ Source program, Assembly Program
T/F: In a Unix type system, every I/O device is modeled as a
file. - correct answer ✔✔ True
T/F: Multi-core processors have
several CPUs, or cores, integrated onto a single integrated-circuit (IC) chip. - correct answer ✔✔
True
T/F: The principles of concurrency
started being formulated when
multi-core processors where introduced
into desktop computers around 2002. - correct answer ✔✔ False
T/F: The advent of of multi-core
, and hyper-threaded systems has greatly increased the desire to find ways to
write application programs that
can exploit the thread-level parallelism available with these systems. - correct answer ✔✔ True
T/F: Taking advantage of computer level parallelism, a single-core modern processor can
execute multiple
instructions at one time. - correct answer ✔✔ False
Instruction Set Architecture - correct answer ✔✔ Describes the effect
of each machine‐code instruction.
Microarchitecture - correct answer ✔✔ Describes how the processor is actually implemented.
CPU/Processor - correct answer ✔✔ The engine that interprets instructions stored in main
memory. Appears to execute instructions in strict sequence, executing one after another.
Process - correct answer ✔✔ Operating system's abstraction for a running program.
operating system - correct answer ✔✔ Provide applications with simple and uniform
mechanisms for manipulating complicated and often wildly different low‐level
hardware devices.
Kernel - correct answer ✔✔ The portion of the operating system code that is always resident in
memory.
System Call - correct answer ✔✔ Used by an application program to request some service from
the
operating system.
