  • MicroDIMM
    A RAM (random access memory) module designed for subcompact and laptop computers.
  • Storage
    - Long-term data
    - Retains information after shut down
    - Maintains devices, components, media
    - Examples: SSD, SSHD
  • Memory
    - Clears when computer is shut off
    - Short-term dataSpeed
    - Performance
    - Size limitations
    - Examples: SoDIMM, MicroDIMM
  • Direct Current (DC)

    - Current used by digital devices
    - Flows in one direction
  • Alternating Current (AC)

    - Current used by houses and buildings through outlets
    - Flows in more than one direction
  • AC Adapter
    A device that converts AC to DC and can use regular house current to power a laptop computer.
  • Wireless Cards
    A device that adds wireless connectivity to a laptop or desktop computer.
