Computing tools and activities
Binary Tools
Floating Point Binary Activity
An activity to practice converting between denary real numbers and binary mantissa/exponent form. Includes error calculations when the conversion invovles an approximation.
Floating Point Binary Conversions
A tool to convert between denary real numbers and binary mantissa/exponent form.
Number Systems
A tool to convert between binary,denary and hexadecimal.
Truth Table
A tools to create a truth table for an expression containing two, three or four Boolean variables
Encryption Resources
Caesar Cipher
A tool to generate a Caesar cipher with a give shift from text and an activity to practice decoding encrypted messages
Polyalphabetic Cipher
A tool to generates a Polyalphabetic cipher with a give shift values from text and an activity to practice decoding encrypted messages
RSA Activity
A tool to generates an RSA cipher with given keys from text and an activity to practice decoding encrypted messages. There are also activities to practice the number theory concept required by RSA Cryptography.
Vernam Cipher
A tool to generates a Varnam cipher with a given alphabet from text and an activity to practice decoding encrypted messages
