   Twin USB-drives. A USB drive is also called a thumb drive. Twinning them   
   simply means have 2 slots for such a drive. Modern computers typically   
   have anywhere from 4 to 10 slots.   
      
   A laser printer is a type of printer using a heated drum to attract and   
   then deposit very fine ink particles on the page. The heat then fuses   
   these particles to form a very sharp image, whether text or photo.   
      
   A 64 bit machine is one that operates on 64 bit of data at once.   
   Windows7 and later are 64 bit operating systems.   
      
   A VDU is a video display unit -- what we call a monitor.   
      
   A hard-drive is a device for storing data encoded onto a metallic disk   
   via a magnetic process. Technically, only a spinning disk is a   
   hard-drive but we use the term to include Solid-state drives as well.   
   And before you ask, a solid-state drive is simply a USB drive in a   
   different physical shape.   
      
   A daisy-wheel was a type of printer that used a typewriter ribbon and a   
   spinning (daisy-wheel) disk. The disk was spun until the desired   
   character was in place, then struck through the ribbon onto the paper.   
   They were soon replaced by the dot-matrix printer, which then gave way   
   to the laser printer.   
      
      
      
      
   Cheers... Dallas
