Loop program
-
Program trace
-
Sub-routine program
-
Byte sorting program
B
Correct answer
Explanation
A program trace is a record of the execution of a computer program, showing the state of registers and memory at specific points.
B
Correct answer
Explanation
Accessing data on a tape is sequential, meaning you must pass through previous items to reach a specific one, similar to a queue.
-
RAID level 0
-
RAID level 1
-
RAID level 4
-
RAID level 2
-
RAID level 3
C
Correct answer
Explanation
This level of RAID technology in memory management consist of block-interleaved parity organisation that stores blocks just like in regular disks without stripping them across disks.
-
CDs of historical places
-
CDs of science experiments
-
CDs of animals
-
CDs of music
B
Correct answer
Explanation
Science experiment CDs provide visual demonstrations of complex concepts that are often difficult to perform in a classroom. This makes them highly useful for student learning.
-
Free disk space
-
Frequent backups
-
Fast process
-
None of these
A
Correct answer
Explanation
A print server manages print jobs by spooling them to disk before sending them to the printer. Therefore, sufficient free disk space is critical to handle multiple or large print jobs without failure.
-
Hard Disk
-
Main Memory
-
Registers
-
None of these
C
Correct answer
Explanation
Registers are the fastest type of memory in a computer system, located directly inside the CPU to provide immediate access to data for processing. Hard disks are secondary storage, and main memory (RAM) is slower and external to the processor core.
B
Correct answer
Explanation
Computer storage media is generally categorized into three types: primary storage (RAM/ROM), secondary storage (HDD/SSD/Optical), and tertiary storage (tape libraries).
-
matrix scanning
-
raster scan
-
optical recording
-
coding
C
Correct answer
Explanation
Optical recording technology uses laser beams to burn microscopic pits.
-
Main memory
-
Auxiliary memory
-
Cache
-
ROM
C
Correct answer
Explanation
It is a high speed memory called as static RAM required to hold most recently used data.
-
Cache memory
-
Main memory
-
Magnetic memory
-
Memory address register
D
Correct answer
Explanation
MAR holds the address information of the data, which has to be fetched from the memory.
-
4.7 GB
-
9.5 GB
-
17 GB
-
8.5 GB
D
Correct answer
Explanation
This is correct, because the size of single-sided, single-layered DVD is 4.7 GB. Therefore, the size of this DVD will be just double of it.
-
BIOS chip
-
CMOS chip
-
RAM
-
Motherboard
D
Correct answer
Explanation
CMOS battery is installed on the motherboard because there is a particular socket made for on-the-motherboard, which helps in showing the date and time on the system.
-
Speedy memory
-
Bubble memory
-
Write only memory
-
Flash memory
D
Correct answer
Explanation
MP3 players use non-volatile storage known as flash memory to store music files. This allows data to be retained even when the power is turned off.
-
Audit
-
