,SECTION 1: COMPUTER ABSTRACTIONS AND TECHNOLOGY
Question 1
Which of the following is NOT one of the five classic components of a
computer
A. Datapath
B. Control
C. Cache controller
D. Memory
Correct Answer C
Rationale The five classic components of a computer are Datapath,
Control, Memory, Input, and Output. A cache controller is a
subcomponent of the memory hierarchy, not one of the five primary
components .
Question 2
The instruction set architecture or ISA serves as the
A. Physical layout of transistors
B. Contract between hardware and lowest-level software
,C. Internal organization of the ALU
D. Power management unit
Correct Answer B
Rationale The ISA is the abstract interface that separates machine
language from implementation details. It defines the instructions,
registers, and memory model that software can rely upon regardless of
the specific hardware implementation .
Question 3
A server is best described as
A. A personal computer for office tasks
B. A computer running larger programs for multiple users, often
accessed via a network
C. A specialized embedded system
D. A supercomputer for weather modeling
Correct Answer B
Rationale Servers are network-connected computers designed to provide
services such as database web hosting and large computations to many
, simultaneous users, typically with higher reliability and throughput than
personal computers .
Question 4
Moores Law states that integrated circuit resources double
approximately every
A. 6 months
B. 12 to 15 months
C. 18 to 24 months
D. 36 months
Correct Answer C
Rationale Gordon Moore observed in 1965 that transistor density on
integrated circuits doubles every 18 to 24 months. This drove
exponential performance growth for decades, though physical limits are
now slowing this trend .
Question 5
Which of the following is an example of systems software
A. Web browser
