So, Technical Data used in the field explained in computer courses in Rawalpindi.  except some basic information about system configuration, like where from to receive (input) electro-magnetic pulses and where to send (output) the processed results, no other  information is stored in the ROM.

Usual size of Hard Disks now available ranges from 80 GB and above; the CD has capacity of 720 MB, DVD h as 4 GB and PEN Drives have capacity from 2 GB to 16 GB.
