Study Notes

Operating Systems

  • An operating system (OS) manages system resources, including RAM.
  • Virtual machines allow multiple operating systems to run on one computer.
  • Desktop environments in Linux, Microsoft Windows, and MacOS support file and app icon placement on the desktop.

User Interfaces

  • Both desktop and mobile operating systems feature a graphical user interface (GUI).
  • Mobile operating systems are optimized for touch screens, file transfer, and WiFi connectivity.

App and File Management

  • A mobile app is distinct from a desktop app; they are not interchangeable.
  • Spooling allows the OS to manage multiple print jobs efficiently.
  • Most file managers provide options to create folders through the Save dialog box.

File Operations

  • In Windows, multiple non-sequential files can be selected using the CTRL key.
  • Moving a folder does not create a copy; it relocates the folder to a new location.
  • Clicking the Save button does not guarantee saving to the hard drive; it depends on selected options.

Notifications and Features

  • A small notification on an app icon is called a badge, indicating alerts or information.
  • Common Bluetooth device problems include signal interference, low battery, and pairing issues.

Device Management

  • Shutting down a device powers it off completely.
  • File compression is useful for emailing large files, creating archives, and saving storage space.
  • Ensuring devices like LCD monitors, smartphones, TVs, and laptops are recycled is important for environmental sustainability.

Software and App Types

  • A virtual machine is an emulation of a computer system.
  • All database software stores data in tables, and database administrators manage security, user access, and operations.
  • Vector graphics use mathematical instructions for creating images, while bitmap graphics rely on pixel data.

Media and Applications

  • On-demand media is available anytime a user chooses and may not always be free.
  • Web apps can have immediate accessibility and may store data online or in the cloud.
  • Video conference services typically enable file sharing, screen sharing, and collaborative whiteboards.

General Technology Awareness

  • It’s essential to recognize ergonomic guidelines to reduce strain while using technology.
  • Signs of excessive Internet use include irritability when offline and sleep deprivation.
  • Encryption is a security feature but is not a substitute for a firewall.
  • Address spoofing can disguise the true destination of an online communication.

Additional Notes

  • Brownouts can negatively impact electronic components over time.
