Memory & Storage
Practice Memory & Storage MCQs for Pakistan exams (CSS, FPSC, PPSC, NTS) — 51 practice questions with answers and explanations.
How to use these questions
Memory & Storage on MCQsHub is 51 published questions for Pakistan exams such as CSS, FPSC, PPSC, and NTS. Open a question, choose an option, then read the explanation before you move on. The explanation names the correct choice and why the other options do not fit. Difficulty labels and topic tags show which idea to revise next, instead of repeating questions you already know.
Previous and next links on each question page stay inside Memory & Storage, so you can work through the subject without returning to this index. Subtopics listed here belong to the same subject and narrow the set. When you want a clock and a score, start a timed quiz for Memory & Storage. When you want a whole sitting rather than one question, open the past-paper library. New Memory & Storage questions appear here after editorial review.
The list below starts with the newest Memory & Storage questions. Later pages keep the same subject. Each title is a link to the full stem, the options, and the explanation.
What is the name for the process of reorganizing fragmented data on a storage disk so files are stored in contiguous blocks? Which of the following best describes Disk defragmentation? Identify the correct concept described as: the rate at which data can be read from or written to memory, usually measured in bytes per second. Memory bandwidth is best defined as which of the following? A condition where a system spends most of its time swapping data between memory and disk rather than executing useful work. What is this concept called? Choose the correct description of Thrashing. Which of the following best names the concept in which the fastest and smallest storage tier in a computer, located directly inside the CPU? What is the function or purpose of Register memory? The concept in which a high-speed storage interface protocol designed specifically for solid-state drives connected via PCIe is best known as which of these terms? Identify the correct definition of NVMe. What term describes the following? a copy of data stored separately from the original, used to restore information in case of loss or damage. In computer science, Data backup refers to which of the following? Select the correct name for: a storage tier used for data that is rarely accessed, prioritizing low cost over fast retrieval speed. The concept in which memory directly accessible by the CPU, such as RAM, used to store data currently being processed is best known as which of these terms? Identify the correct definition of Primary memory. What term describes the following? a storage tier typically used for archival purposes, such as tape drives, that is slower and accessed less frequently. In computer science, Tertiary storage refers to which of the following? Select the correct name for: a storage device that uses integrated circuits to store data persistently, with no moving mechanical parts. Which statement correctly explains Solid-state drive (SSD)? Which concept is defined as follows: a sequential storage medium that records data as magnetic patterns along a long strip of tape, often used for backups?
