• Factors to consider when choosing a case fan:

  • Case size
  • Fan speed
  • Number of components
  • Physical environment
  • Number of mounting places available
  • Location of mounting places available
  • Electrical connections

  
• Factors to consider when choosing a power supply:

  • Type of motherboard
  • Required wattage
  • Number of components
  • Type of components
  • Type of case

  
• A computer motherboard is the main circuit board that connects all the different parts of the computer together

  
• Factors to consider when choosing a CPU heat sink or fan:

  • Socket type
  • Motherboard physical specifications
  • Case size
  • Physical environment

  
• When assembling a computer, it's important to:

  • Define general and fire safety standards
  • Connect the power supply
  • Install the motherboard components
  • Install internal drives
  • Install the adapter cards
  • Identify additional storage
  • Connect computer components with appropriate cables
• Safety precautions when working with computers include:

  • Removing watches or jewelry
  • Turning off and unplugging equipment
  • Removing clutter from workspace
  • Covering sharp edges inside the computer
  • Wearing safety goggles
  • Following proper lifting procedures
  • Knowing fire extinguisher availability, rating, and use
• When selecting a computer case:

  • Consider the model type that matches the motherboard
  • Ensure the size accommodates the components for proper airflow
  • Match the power supply rating and connection type to the motherboard
  • Choose based on appearance, status display, and vents for cooling
• Case fans should be installed to move cooler air into the computer case while moving heat out of the case
• Power supplies convert AC input to DC output voltages, providing 3.3V, 5V, and 12V, measured in wattage
• When selecting a motherboard, ensure compatibility with CPU, RAM, video adapter, and existing components
• Processors are classified as 32-bit and 64-bit, with considerations for speed, heat generation, and front-side bus frequency
• CPUs require cooling systems like air-cooled or liquid-cooled heat sinks with fans to prevent overheating
• New RAM may be needed if the computer displays errors, and it must be supported by the chipset
• Types of drive bays commonly found in computer cases:

  • Width of each type of drive bay
  • Description of the types of devices typically installed in each type of bay

  
• Installation of a hard disk drive (HDD) into a computer case:

  • Mount the HDD on the side of the case using four screws

  
• Installation of a DVD drive into a computer case

  
• PCI Express slot on a computer motherboard

  
• Installation of RAM into a computer

  
• Hard drives are used to store data on computers, made up of platters that spin around and read/write data

  
• Capabilities of different optical disc drives

  
• The image is of a media reader

  
• Attachment is a strong reciprocal emotional bond between an infant and a primary caregiver

  
• Schaffer and Emerson's 1964 study on attachment:

  • Aim: identify stages of attachment / find a pattern in the development of an attachment between infants and parents
  • Participants: 60 babies from Glasgow
  • Procedure: analysed interactions between infants and carers
  • Findings: babies of parents/carers with 'sensitive responsiveness' were more likely to have formed an attachment
• Freud's superego is the moral component of the psyche, representing internalized societal values and standards
• Hard drives are used to store data on computers, made up of platters that spin around and read/write data, can be internal or external, using technologies like HDD, SSD, or SSHD

  
• Media reader: Choose based on current and future needs, supports formats like SD, MicroSD, MiniSD, CompactFlash, Memory Stick, xD
• External storage devices connect using USB, eSATA, or Thunderbolt ports, choose based on data transfer needs
• Installation steps for connecting internal power cables:

  • Align 24-pin ATX power connector to motherboard socket
  • Press down until clip clicks into place
  • Align 4-pin auxiliary power connector to motherboard socket
  • Press down until clip clicks into place
  • Align CPU fan power connector to motherboard socket
  • Press down until clip clicks into place
• Installation steps for connecting internal data cables:

  • Align SATA cable and plug one end into motherboard socket
  • Plug the other end into the smaller SATA port on the drive
• Installation steps for connecting front panel cables:

  • Plug power, reset, power LED, drive activity LED, speaker, USB, and audio cables into respective connectors
• Front panel connectors include power button, reset button, power LED, drive activity LEDs, system speaker, and audio, consult documentation for specific instructions
• USB motherboard connectors: often 9 or 10 pins arranged in two rows, connect to USB motherboard connectors for USB 3.0 or USB 3.1 capabilities
• If a button or LED doesn't function, the connector may be incorrectly oriented, correct by turning the connector around, manufacturers may include keyed pin extenders to combine multiple front-panel cables
• Complete computer assembly steps:

  • Reattach front panel
  • Plug power cable into power supply
  • Connect USB, video, network, and audio cables
  • Place side panel cover onto case and secure with screws
