   • LAPTOPS
     • IT IS VERY MOBILE, IT CAN BE OPERATED OFFLINE AND ALSO IT HAS WIFI ACCESS
   • TABLES
     • BY USING THEM YOU CAN ORGANIZE A LOT OF DATA IN VERY EASY WAY ,

     • THEY ARE VERY BIG AND ALSO ARE VERY EXPEMSIVE AND UNEASY TO MANTAIN
   • LAPTOPS
     • IT DOES NOT HAVE A LOT A CAPACITY AND IT HAS LESS POWER THAN A DESKTOP

4. EMERGING TECHNOLOGIES

   • THESE ARE NEW TECHNOLOGIES THAT ARE INNOVATIVE AND HELP PEOPLE IN DIFERENT AND NEW WAYS THAT NO ONE HAS EVER SEEN
