Computer Memory and Storage Questions

Multiple choice
  1. write a file to a disk

  2. delete a file to a disk

  3. format the harddisk

  4. both b and c

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Distributed service support

  2. Access control

  3. Database buffer cache

  4. Page based DSM

  5. 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.

Multiple choice
  1. My Pictures

  2. My Recent Documents

  3. My Music

  4. My Computer

  5. My Documents

D Correct answer
Explanation

This folder in Windows XP is the one which gives you access to and information about the disk drives, cameras, scanners and other hardware devices connected to the computer.

Multiple choice
  1. Flash memory

  2. CMOS

  3. Bays

  4. Buses

  5. 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.

Multiple choice
  1. RAM

  2. ROM

  3. The CPU

  4. Flash memory

  5. The CD-ROM

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. RAM

  2. DSL

  3. USB

  4. LAN

  5. CPU

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. A random-access medium

  2. A sequential-access medium

  3. A read-only medium

  4. Fragile and easily damaged

  5. An expensive storage medium

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. ROM

  2. Hard drive

  3. Diskette

  4. Dashboard

  5. Clipboard

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. storage device

  2. software

  3. memory

  4. hardware

Reveal answer Fill a bubble to check yourself
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.
