    Study Notes

    Choosing an Operating System

    • Stability and robustness: Choose an OS that can handle tasks efficiently without crashing. Seek advice from developers and users with similar systems.
    • Memory management: Look for an OS that effectively manages primary memory and processes between main memory and the disk. Proper memory management ensures data accuracy, availability, and consistency.
    • Memory leaks: Avoid OS with memory leaks, where processes request memory and don't release it, potentially causing high memory demand. Defragmentation can help regroup memory fragments.

    Computer Maintenance Tips

    • Always shut down your computer properly before turning off the power.
    • Use a UPS (Uninterrupted Power Supply) for your computer.
    • Regularly back up your data to external hard drives, DVD/CD-ROMs, USB drives, or memory cards.
    • Run scan disk and defragmentation at least once a month.
    • Never unplug peripherals from the computer while it's on.
    • Ensure 300-600 MBs of free space on your C Drive for Windows XP, Vista, or Windows 7.
    • Limit the number of programs that load at startup.
    • Use an antivirus checker and a firewall program regularly.
    • Keep track of software disks and new peripherals.
    • Enable Windows updates.

    System Requirements

    • System requirements or software requirements specify the necessary programs and hardware for operating a program or game.
    • System requirements are printed on packaging or found online.
    • If your computer doesn't meet the minimum requirements, the program may not install or run.
    • Computers meeting minimum but not suggested requirements may experience slow performance.
    • Upgrading RAM, hard drive, or video card can help meet requirements.
    • Upgrading the processor might require a new motherboard.
    • If the processor doesn't meet requirements, consider getting a new computer.

    Occupational Health and Safety Policies

    • Occupational Health and Safety (OHS) Policies aim to protect the health, safety, and welfare of all individuals in the workplace.
    • Employers are legally obligated to provide a safe work environment.
    • Here are examples of OHS policies:
      • Do not work alone, always have backup for emergencies.
      • Power off and unplug computers before working on them.
      • Keep liquids away from working areas to prevent electrocution and damage.
      • Use tools carefully to avoid short circuits.

    Material Safety Data Sheet (MSDS)

    • An MSDS provides information about potential hazards associated with a chemical product. It includes handling, storage, use, and emergency procedures.
    • MSDSs are prepared by the supplier or manufacturer and contain more details than product labels.
    • The nine categories of information on an MSDS in Canada are:
      • Product Information: identifier, manufacturer, and supplier details
      • Hazardous Ingredients
      • Physical Data
      • Fire or Explosion Hazard Data
      • Reactivity Data
      • Toxicological Properties: health effects
      • Preventive Measures
      • First Aid Measures
      • Preparation Information: responsible party and preparation date

    Computer Component Proper Disposal

    • Proper disposal or recycling of hazardous computer components is crucial to protect the environment.
    • Organizations violating disposal regulations face fines and legal challenges.
    • Batteries often contain harmful rare earth metals requiring specific disposal procedures.

    Operating System Installation

    • Each operating system has unique installation steps and requirements.
    • General steps to install an operating system on a hard drive:
      • Purchase the operating system from a retail store or online.
      • Configure the computer to boot from the CD/DVD drive or USB flash drive.
      • The operating system installation program guides the user through the process.
      • Answer questions about basic settings such as date, time, user accounts, and automatic updates.
