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

What is hexadecimal?
From binary model...
…to machine
Types of Computer
Mainframe Mini(computer) Workstation (UNIX) Microcomputer

Other Types?
Think of the uses of computers
Remind me to tell you the story about the fan...
Is the computer just a tool?
How is it a cultural artefact?
Some computer uses
As a fancy calculator As a fancy typewriter As a controller for other devices 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?
