,Quiz_________________?
(busy time / total time) × 100% -
Answer✅
CPU utilization
Quiz_________________?
(Hamming code/Huffman code) adds a set number of parity bits to a data block (e.g., 7 bits
for 4 bits of data). -
Answer✅
Hamming code
Quiz_________________?
(Hamming code/Huffman code) assigns shorter codes to frequent symbols and longer codes
to rare ones. -
Answer✅
Huffman code
Quiz_________________?
A block-level protocol that transports SCSI commands over TCP/IP, appearing to the OS as
a locally attached raw hard drive. -
Answer✅
iSCSI (block-level) (Internet Small Computer System Interface)
Quiz_________________?
A company needs to ensure consistent performance by decreasing the density of bits from
inner tracks to outer tracks. Which hard disk method should be used? -
2
, Answer✅
Constant angular velocity
Quiz_________________?
A company requires a computing environment that supports high-volume data processing
and the management of a large amount of storage. Which computing environment should
the company use? -
Answer✅
Mainframe
Quiz_________________?
A dedicated file storage device accessible over a network, acting as a centralized file server.
-
Answer✅
NAS (Network Attached Storage)
Quiz_________________?
A disk's access time is composed of three parts. Which takes the longest on traditional
HDDs? -
Answer✅
Seek time
(Seek time (moving the arm to the correct cylinder) is typically the largest component of
HDD access time — often 5-15ms. Rotational latency averages half a rotation period. Data
transfer is fast once positioned.)
3
, Quiz_________________?
A file-level protocol used by NAS, mainly for Windows environments (shared folders). -
Answer✅
CIFS/SMB (file-level) (Common Internet File System/Server Message Block)
Quiz_________________?
A logical address has 16 bits. The page size is 512 bytes. How many bits are used for the
page offset? -
Answer✅
9 bits
(Page size = 512 = 2^9 bytes. To address any byte within a 512-byte page, you need 9 bits
for the offset. The remaining 16-9 = 7 bits identify the page number, giving 2^7 = 128 pages
maximum.)
Quiz_________________?
A page fault rate is very low. What might this indicate about frame allocation? -
Answer✅
The process has too many frames allocated — it could release some to other processes
with minimal performance impact.
(Very low page fault rate suggests the process has more frames than its working set needs.
The PFF (page-fault-frequency) algorithm would detect this and reclaim frames to give to
processes with higher fault rates — improving overall system utilization without hurting the
over-allocated process.)
