1. A technician is asked to determine how many processing operations a
computer can complete in a fixed interval. If a system completes 480
operations in 12 seconds at a constant rate, how many operations
should it complete in 25 seconds if the processing rate remains
unchanged?
A. 800
B. 900
C. 1,000
D. 1,200
The system processes 480 ÷ 12 = 40 operations per second. Multiplying 40
by 25 seconds gives 1,000 operations.
, 2. A digital system contains 64 memory locations, and each location can
store exactly 8 bits. How many total bits can the entire memory store?
A. 256 bits
B. 384 bits
C. 512 bits
D. 1,024 bits
Each of the 64 locations stores 8 bits, so the total capacity is 64 × 8 = 512
bits.
3. A signal travels through a processing circuit at a constant rate. If it
takes 6 microseconds to travel 18 meters, how far will the signal travel
in 15 microseconds under identical conditions?
A. 30 meters
B. 36 meters
C. 45 meters
D. 54 meters
The signal travels 18 ÷ 6 = 3 meters per microsecond. In 15 microseconds, it
therefore travels 45 meters.
4. A computer program requires 15 seconds to process 3,000 records.
Assuming the processing rate remains constant, approximately how
many records can it process in 2 minutes?
,A. 18,000
B. 20,000
C. 24,000
D. 30,000
The processing rate is 3,000 ÷ 15 = 200 records per second. Two minutes is
120 seconds, so 200 × 120 = 24,000 records.
5. A technician observes that a storage device has 75 percent of its 800-
megabyte capacity available. How many megabytes are currently
available?
A. 500 MB
B. 600 MB
C. 625 MB
D. 650 MB
Seventy-five percent of 800 MB is 0.75 × 800 = 600 MB.
6. A system has a processing speed of 2.4 million operations per second.
Another system operates at 3.6 million operations per second. By
what percentage is the second system faster than the first?
A. 25%
B. 50%
, C. 60%
D. 75%
The increase is 3.6 − 2.4 = 1.2 million operations per second. Dividing 1.2 by
2.4 gives 0.50, or a 50 percent increase.
7. A data file contains 2,400 records. During transmission, 15 percent of
the records are rejected and must be retransmitted. How many
records must be retransmitted?
A. 240
B. 300
C. 360
D. 400
Fifteen percent of 2,400 is 0.15 × 2,400 = 360 records.
8. A technician divides a 960-unit data block into 12 equal sections. How
many units are contained in each section?
A. 60
B. 70
C. 80
D. 90
Dividing 960 by 12 gives 80 units per section.
