[컴활2급 필기] 1.6Windows10

Main ideas and lessons (Windows 10 study approach + key features)

Learning strategy for the exam

Instead of trying to learn every Windows concept from scratch, the speaker recommends:

• Solve frequently asked past exam questions first
• Then, from those questions, extract and organize the underlying concepts
• Lectures are structured as: question solving → concept extraction

Windows 10 commonly tested features / concepts

1. OLE (Object Linking and Embedding)

   • Purpose: Connect or embed objects created in other apps into the document you’re working on.
   • Embedding vs. linking
     • Embedding/insert: Changes in the original do not significantly affect the inserted content.
     • Linking: Changes in the original object are reflected in the linked content.

2. Plug and Play (PnP)

   • Purpose: The OS automatically performs necessary settings when new hardware is added.
   • Example: Plug in a USB drive and use it without extra configuration.

3. GUI (Graphical User Interface)

   • Purpose: Operate the computer by clicking icons/menus rather than typing commands.

4. Preemptive multitasking

   • Purpose: The OS controls CPU time for each application.
   • Behavior on failure: If an app freezes/crashes, the OS can forcibly terminate it and release system resources (CPU, memory, etc.).

5. Aero Peek

   • Behavior: Hover over a running program’s icon on the taskbar to see a minimized preview.
   • Related concepts
     • Show Desktop minimizes windows to reveal the desktop.
     • Shortcut: Start + D
   • Exam focus: Understand Aero Peek as preview/hover-based visibility.

Study methodology (as presented)

How the lecture recommends studying for Windows (explicit methodology)

• Solve frequently asked past exam questions first.
• For each question:
  • identify the relevant Windows feature/definition
  • extract the key concept
  • organize it for later recall
• This approach helps prevent:
  • concepts that don’t stick when learned purely as definitions
  • feeling overwhelmed because the material is too broad

Practical steps demonstrated (computer exercises)

• Aero Peek demonstration

  • Hover over a taskbar icon of a running program (e.g., multiple Chrome windows)
  • Observe the preview (minimized/hover preview)
  • Use Show Desktop at the far-right bottom of the taskbar
  • Shortcut: Start + D (toggles desktop visibility)

• Firewall location check (Windows)

  • Go to Control Panel → System and Security
  • Open Windows Firewall settings / related pages to verify options

• Recycle Bin properties check

  • Right-click Recycle Bin on the desktop → Properties
  • Find the option to remove files immediately upon deletion (bypasses Recycle Bin)

• Drive optimization scheduling check

  • Right-click a drive (e.g., C:) → Properties
  • Look for Drive Optimization and Defragmentation
  • Open Optimization and verify scheduling settings (Scheduled Optimization)

• Shortcut icon properties check

  • Create/locate a shortcut (example: Excel)
  • Right-click shortcut → Properties
  • View:
    • Target / target location
    • Target format
    • date/access/modification info
  • Confirm shortcut extension is .lnk

• Folder Options check (File Explorer)

  • File Explorer → View tab
  • Options → Change folder and search options
  • Review tabs: General / View / Search

Question-based concept highlights (what each choice teaches)

Question 1 (PnP)

• Correct: Plug and Play (PnP) is the OS function that automatically recognizes/sets up new hardware.

Question 2 (Aero Peek)

• Correct: Aero Peek corresponds to:
  • Hover taskbar icon → preview of windows/desktop
• Other options are treated as not belonging to Aero Peek:
  • Library (grouping media)
  • Desktop slideshow background
  • Recently opened files via right-click taskbar icon

Questions 3–5 (Windows Firewall)

Core firewall idea (with analogy):

• Firewall checks packets/data entering from outside to inside
• Allows only authenticated/allowed incoming data
• Can’t prevent internal misuse/hacking from inside

• Mentions trace/logging concept (finding traces of external intruders)

• Question 3: choose the incorrect firewall description

  • “Virus infection via notifications” is considered antivirus, not firewall.
• Question 4: choose statement alignment about company firewall management
  • Managed by a security department; users request access to communicate externally
  • “Active defense” idea explained as default deny, allow as needed
  • Firewall alone can’t fully prevent phishing (as described)
  • Firewall can’t stop internal hacking
• Question 5: choose the not appropriate reason for using a firewall
  • “Perfect external security and blocking illegal internal hacking” is treated as wrong because internal hacking can’t be blocked by firewall.

Questions 6–8 (Recycle Bin)

• Basics

  • Stored on C:\Recycle Bin
  • When capacity exceeds, oldest deleted items are removed first
  • Cannot rename/execute items directly while in Recycle Bin—you must restore first
  • Settings can be changed, including per-drive recycle bin capacity

• Immediate deletion cases

  • Shift + Delete
  • Option in Recycle Bin properties: “remove files immediately”
  • Deleting from USB / network drive / DOS mode (immediate permanent deletion)

• Question 7: which situations allow recovery

  • Correct: deletion by drag-and-drop into Recycle Bin

• Question 8: case where deleted file is directly deleted without going to Recycle Bin

  • Correct: USB/network/DOS-mode style external deletion (not normal C-drive deletion)

Questions 9–10 (Disk optimization)

Three concepts:

• Error checking: checks HDD/SSD damage and repairs recoverable errors
• Disk Cleanup: deletes unnecessary files to free disk space

• Drive optimization / defragmentation:

  • removes fragmentation by gathering scattered pieces
  • improves disk access speed
  • does not increase disk capacity

• Question 9: correct description of Disk Cleanup

  • Correct: freeing space by deleting unnecessary files
• Question 10: incorrect description of optimization/defragmentation
  • Incorrect: claims disk capacity increases (capacity does not increase)

Questions 11–12 (Shortcut icons)

• Shortcut basics

  • Shortcut icon extension is .lnk
  • Stores the location/target of the original file
  • Running the shortcut executes the original (if it still exists)
  • Multiple shortcuts can point to one source file, but the shortcut icon is described as linking to one target

• Question 11: incorrect statement

  • Incorrect: “linking multiple source files to one shortcut icon”
• Question 12: incorrect description
  • Incorrect: shortcut can run even if the original file is deleted
  • Another incorrect idea mentioned: treating the option as “only linking one shortcut icon” (considered wrong due to dependency on the original file)

Questions 13–14 (Folder Options in File Explorer)

• Folder Options structure

  • General tab
    • Open folders in same window vs three windows
    • Open with one click vs two clicks
    • Show recently used files/folders in Favorites
  • View tab
    • Visibility settings (hidden files, file extensions, etc.)
  • Search tab
    • Index/search settings and whether to use indexing

• Question 13: which operation is NOT correct in Folder Options

  • Setting a password for a folder is treated as not supported
• Question 14: which action is NOT correct to set in Folder Options
  • Deleting recently used files in Favorites is treated as not a Folder Options setting
  • Instead: use context menu such as Remove from Favorites
