Logical and Computational Thinking

Logical and Computational Thinking

1. Algorithm

   • Series of steps to do something
     • Precise
     • FInite
     • Defined
     • ordered

2. Computer

   • Accepts inputs and outputs
     • Devices
       • Input
         • Key board
         • Mouse
         • Scanners
       • Output
         • Monitor
         • Headphones
   • Has software and hardware
     • Software
       • Operative system
       • Drivers
       • Downloadable programs
     • Hardware
       • Microprocessor
       • RAM
       • GPU
   • It has components
     • Input
     • Output
     • storage device
     • System unit
       • Control unit
       • Arithmetical control unit

3. Data & Information

   • Data has no meaning by its own
     • Simple
       • Numeric
       • Logic/ Boolean
       • alphanumeric
       • Structered data
     • Complex
   • Information is data arranged to give it a meaning

4. Techniques of Computanional Thinking

   • Abstraction
   • Break down
   • Simulation
   • Algorithm development
   • Eilder's
   • Polyal's

5. Variables

   • Double
   • Float
   • Integer
   • String
   • Character
   • Boolean
   • Real
   • Rules
     • Contain up to 255 characters
     • Can't start with a number
     • It only accepts alphanumerical characters and underscores
     • May not contain spaces
