A coaster brake is a backpedal-to-engage brake. A drum brake uses a cable to actuate the brake
mechaninsm. Both of those require a brake arm that extends the axle's leverage and bolts to the left
chainstay.
A disc is a bit larger than a CD and external - you couldn't miss it!
"36" is the number of spoke holes punched in your hubshell.
