8
Components of a Definition
  • General Purpose
  • Stored-Program
  • Electronic
  • Binary Digits
  • Calculating Machine

9
General Purpose
Is it dedicated to one purpose if it can do any
type of calculation? Would a calculator be a
computer?
Is a PDA like this a computer?
10
Stored-Program
How are programs and data loaded into the device?
ENIAC Programmed Manually EDVAC
Stored-Program
11
Electronic
Does it have gears, vacuum tubes, or chips?
Babbages engines were mechanical
12
Binary Digits
How is information stored and manipulated in the
computer?

  • As an extension of your TV
  • As type of toy
  • As a fancy telephone

Use the OED online to look up the etymology
of machine -- how is a computer a machine?
