Computing

1. Programing

   • IF/ELIF/ELSE
     • IF statements are used for creating multiple choices e.g IF answer == 1 print('insert here')
     • ELIF is the same as the if statement but it is used for everything after words e.g. ELIF answer == 2 print('insert here')
     • ELSE statements are if you input any thing other than one of the set answers e.g. ELSE print ('No command')
   • Concartinates are the linking of strings of code together
   • Import
     • Math imports are used to import different types of math equations
     • Time imports can be used to space codes of line apart with the sleep function
     • Date imports can tell you the real time time and date down to the second
     • Random imports choose different choices at random or other things
   • Functions
     • In programming there are many different functions, like print, input and more.
     • There are also different data types for them like intiger , float , ans and others like it

2. Theory

   • Jhon Von Neumann
     • This man created the von neumann system architecture
       • CPU
         • This means central processing unit and can run many different aps at once unlike a calculator or a ATM it has many functions
     • Von Newmann was a physisist and a mathmatician
   • The Computer
     • Central Processing Unit (CPU)
     • Power Supply
     • Memory
       • RAM
       • Hard Drive
     • Graphics Card (GPU)
     • Cooling
       • Fan
       • Water cooling
   • Inputs and outputs
     • An input is what you use to tell the computer something like a touch screen
     • An output is what the computer responds with like printing a letter onto the screen
