Binary Trainer
Binary stops being scary once you watch the place values light up. Flip bits, run the logic, see the number.
one byte, eight switches
A byte is eight bits, each a switch that is either 0 or 1.
Every column has a fixed place value — 128 64 32 16 8 4 2 1.
Flip a bit on and you add its place value to the total. Click the switches, or type a number, and watch it happen.
bitwise logic: AND · OR · XOR · NOT
The same switches drive the logic operators routers and firewalls run millions of times a second. Pick an operation, set the two operands, and read the result column by column.
drill // coming next
Timed drills land here once the learn half feels right: read-the-byte, write-the-byte,
and snap AND / OR / XOR / NOT reps against a running clock. Same console, same math you just watched.
