Computer Memory and Storage Questions
-
Fixed Disk Drive
-
Fixed Distributive Disk
-
Fine Disk Drive
-
Fine Disk Divider
A
Correct answer
Explanation
FDD stands for Fixed Disk Drive in the context of storage hardware.
-
Hard Data Drive
-
Heavy Data Disk
-
Hard Data Disk
-
Hard Disk Drive
D
Correct answer
Explanation
HDD in computer language means Hard Disk Drive. It is the main, and usually largest, data storage device in a computer. The operating system, software titles and most other files are stored in the hard disk drive.
-
Floppy disk
-
Compact disk
-
Zip disk
-
Chin disk
A
Correct answer
Explanation
Correct Answer: Floppy disk
Floppy disks are enclosed in plastic covers to protect them from damages.
-
Front side bus
-
AGP bus
-
ADF bus
-
Pie bus
A
Correct answer
Explanation
The Front Side Bus (FSB) is the communication interface between the CPU and the memory controller hub, often referred to as the processor bus or memory bus.
-
Floppy disk
-
Scanner
-
RAM
-
Hard disk
A
Correct answer
Explanation
A floppy disk is a removable magnetic storage medium that was widely used in the past but is now obsolete.

-
CPU
B
Correct answer
Explanation
The Memory Data Register (MDR) is the register in a computer's processor that stores the data being transferred to and from the immediate access store.
-
to free memory space
-
to allocate memory space
-
both of the above
-
none of the above
B
Correct answer
Explanation
The calloc function stands for 'contiguous allocation' and is used to allocate memory space for an array of elements, initializing them to zero.
-
it requires more memory
-
it requires less memory
-
it is inefficient
-
none of the above
A
Correct answer
Explanation
Breadth-First Search (BFS) must store all nodes at the current depth level in the queue, which leads to exponential memory usage as the search tree grows. Depth-First Search (DFS) only needs to store the current path, making it more memory-efficient.
-
CPU
-
Monitor
-
USER
-
All the above
A
Correct answer
Explanation
The CPU (Central Processing Unit) requires primary memory (RAM) to store the instructions and data it is currently processing. Other options like Monitor or User do not directly utilize primary memory in this context.
-
small
-
big
-
medium
-
all the above
A
Correct answer
Explanation
Cache memory is a small, high-speed memory located close to or inside the CPU to store frequently accessed data, significantly improving overall system performance.
-
input/output port
-
instruction cycle
-
CPU
-
stack pointer
-
none of these
D
Correct answer
Explanation
The CPU address register called stack pointer automatically keeps track of the stack entry point.
-
Flash
-
Flange
-
Fury
-
FRAM
-
ROM
A
Correct answer
Explanation
It is commonly used in MP3 players, computer BIOS code and thumb drives. Originally developed in Japan by Toshiba, it has become quite popular for products requiring non-volatile erasable memory. Flash devices have a limited number of erase cycles (typically 10,000 to 1,000,000 cycles), so they're not as good a choice for applications in which the data changes constantly. However, since it has no moving parts (unlike a hard disk), it is an excellent choice for storing the operating code for small personal electronics like PDAs, cellphones, digital cameras and the data in items like MP3 players.
-
Video Home System
-
Very High Speed
-
Video Horizontal Standard
-
Voltage House Standard
-
None of these
A
Correct answer
Explanation
JVC (Japan Victor Corporation) and Matsushita (Panasonic) developed the VHS format to compete with Sony which developed the Beta format as the first home video cassette recorder. VHS originally stood for Vertical Helical Scan, but now means Video Home System.
