M2

• RAM stands out as the primary memory choice for its accessibility and performance
• Zip Drive (Removable Hard Disk)


  • Removable Disk Cartridges, faster access time compared to diskettes but slower than traditional hard disks, allows for the removal and replacement of hard disk cartridges for data transfer
• DVD-ROM Increased Data Storage

  • Pits and lands are much closer than in a CD-ROM
  • Spiral track is much closer, contributing to increased data storage capacity
• Numeric keypad layout designed to offer familiarity to individuals accustomed to calculators and adding machines
• Function Keys


  • Positioned in a line across the top of the keyboard
  • Assignable to specific commands by the current application or operating system
• Keyboard Processor Function


  • Each keyboard is equipped with a small processor
  • Processor monitors the key matrix for continuity, detecting closed circuits
• Mouse


  Primary objective is to translate hand motion into signals for cursor movement
• Movable Type


  A drum, chain or wheel of type is moved so that each character can appear over the print position. At the appropriate time, a hammer strikes the paper against the type, and an ink ribbon prints the required symbol.
• Dot Matrix


  The symbols are built up as they are printed from patterns of dots. The printing itself may be done mechanically with an ink ribbon, by charging the paper electrostatically for later development, or by propelling ink droplets under the control of electrostatic fields.
