Computer Memory and Storage Questions
-
write a file to a disk
-
delete a file to a disk
-
format the harddisk
-
both b and c
D
Correct answer
Explanation
Cookies are simple text files with limited functionality - they store small pieces of data and cannot execute file system operations like writing, deleting, or formatting files. This design prevents malicious websites from causing damage through cookie mechanisms.
-
Distributed service support
-
Access control
-
Database buffer cache
-
Page based DSM
-
Distributive computing
D
Correct answer
Explanation
This technique simulates shared memory at the page level, making it similar to a NUMA machine, except with a much greater penalty for remote references.

Booting
-
Shutdown
-
Exiting
C
Correct answer
Explanation
Booting is the process of loading the operating system from the secondary memory to the primary memory.

Web-based software
-
Business software
-
Real-time software
-
Embedded software
-
System software
D
Correct answer
Explanation
Embedded is the correct answer. It is used in consumer products such as washing machines, etc.
-
RAM
-
Cache memory
-
Flash memory
-
Hard disk
-
Floppy disk
C
Correct answer
Explanation
This type of memory consists of large number of memory cells and can be erased and reprogrammed in blocks instead of one byte at a time.
-
a disk
-

None of these
C
Correct answer
Explanation
Option (3) is the correct answer.
-
storage
-
output
-
input
-
information
-
None of these
A
Correct answer
Explanation
Option (1) is the correct answer.
-
Flash memory
-
CMOS
-
Bays
-
Buses
-
Peripherals
D
Correct answer
Explanation
Buses are the electronic pathways that carry data signals between components on the motherboard. Think of them as the highways or conduits through which information flows between the CPU, memory, and other components. Flash memory is storage, CMOS is memory for BIOS settings, bays hold drives, and peripherals connect externally - none are internal data pathways.

RAM
-
ROM
-
The CPU
-
Flash memory
-
The CD-ROM
A
Correct answer
Explanation
RAM (Random Access Memory) is volatile memory used for temporary storage while you're actively working on files. When you open or edit a document, it's loaded into RAM for fast access. ROM is read-only permanent memory, CPU processes data, flash memory is for storage, and CD-ROM is optical media. Only RAM provides the fast, temporary workspace needed for active document editing.
A
Correct answer
Explanation
RAM (Random Access Memory) is your computer's primary working memory. DSL is an internet connection type, USB is a connection interface/port type, LAN is a network type, and CPU is the processor. Only RAM refers to actual memory hardware that stores data temporarily for active use.
-
A random-access medium
-
A sequential-access medium
-
A read-only medium
-
Fragile and easily damaged
-
An expensive storage medium
B
Correct answer
Explanation
Magnetic tape is a sequential-access medium, meaning you must fast-forward or rewind through all preceding data to reach specific information. This makes it impractical for applications requiring quick random access to specific data. It is not random-access, read-only, particularly fragile, or necessarily expensive.
-
ROM
-
Hard drive
-
Diskette
-
Dashboard
-
Clipboard
E
Correct answer
Explanation
When you cut or copy text/images, Windows stores them temporarily in the Clipboard, a reserved memory location. This allows you to paste the content elsewhere. The Clipboard holds only one item at a time unless enhanced.
-
storage device
-
software
-
memory
-
hardware
C
Correct answer
Explanation
RAM (Random Access Memory) is primary memory - it stores data and programs currently in use for fast access by the CPU. While it's hardware component physically, its function is memory. Storage devices (hard drives, SSDs) provide persistent secondary storage.
