12 What is the primary physical difference between standard desktop RAM (DIMM) and laptop RAM (SO-DIMM)?

13 When installing a stick of RAM into a motherboard slot, how do you visually and physically verify it is securely seated?

14 Because RAM is volatile memory, what happens to the data stored in it when the computer loses power?

15 Which specific BIOS feature allows a user to easily apply pre-configured high-performance RAM timings and speeds instead of standard JEDEC specifications?

16 If a computer emits a continuous series of beeps and fails to boot immediately after building it, which component is most likely improperly seated?

17 Which of the following best describes the function of a motherboard?

18 Which of the following represents the most common standard form factor for full-sized desktop motherboards?

19 What is the primary purpose of PCIe (Peripheral Component Interconnect Express) slots on a motherboard?

20 Which specific interface connector on the motherboard is primarily used to connect internal Hard Disk Drives (HDDs) and CD/DVD Drives?

21 Historically, motherboards featured a two-chip architecture. The Northbridge was responsible for managing communication between the CPU and which other high-speed components?

22 What physically connects the power button located on the outside of the computer case to the motherboard?

23 What does VRM stand for in the context of motherboard components?

24 Which legacy, color-coded port on a motherboard's rear I/O panel was traditionally used to connect mechanical mice (green) and keyboards (purple)?

25 A standard QWERTY keyboard is primarily classified as what type of hardware device?

26 Modern computer mice have largely abandoned the old rubber-ball tracking mechanism. What do they use instead to detect physical movement?

27 What is the standard, universal physical interface used to connect almost all modern external keyboards, mice, and pen-drives to a PC?

28 Which software technology is used alongside a scanner to convert physical, printed text into editable digital text files?

29 The sensitivity and tracking precision of a computer mouse are typically quantified using which metric?

30 Which of the following devices is strictly an output device?

31 What is the primary function of a scanner in a computer setup?

32 Which type of keyboard is defined by having a distinct, individual physical switch under every single key, rather than a single continuous rubber dome sheet?

33 Inside a traditional mechanical Hard Disk Drive (HDD), what is the name of the rigid, rapidly spinning disks coated with magnetic material that actually store the data?

34 The speed at which a Hard Disk Drive's magnetic platters spin is measured in which metric?

35 A pen-drive (also known as a USB flash drive) relies on what specific type of storage medium to hold data without power?

36 Unlike mechanical Hard Disk Drives, Solid State Drives (SSDs) and pen-drives possess what major physical advantage that makes them more durable against drops?

37 To safely prepare a brand-new hard disk so that an operating system can actually read, write, and organize files on it, what must be done first?

38 If you want to format a pen-drive so that individual files larger than can be saved on it, and it can be read/written by both Windows and macOS natively, which file system should you choose?

39 What is a distinct physical indicator often used to differentiate a standard USB 3.0 port or pen-drive connector from older USB 2.0 ones?

40 If a hard disk drive has a rotational speed of , how many revolutions does the platter make in one second?

45 What common colloquial term describes the process of using a CD drive's laser to write data onto a blank CD-R?

46 If a CD is heavily scratched on its clear, reflective bottom surface, what hardware issue is most likely to occur?

47 What does the "ROM" in CD-ROM explicitly indicate about the media?

48 Modern internal CD and DVD drives typically connect to the computer's motherboard using which standard internal data cable interface?

49 When configuring a new hardware device like a USB mouse or keyboard, what does the concept of Plug and Play (PnP) mean?

50 What specific type of software acts as a translator or bridge, allowing an operating system to understand how to communicate with and control a specific hardware piece (like a scanner or advanced mouse)?
