A two-bit binary counter is a digital circuit that counts in binary from 00 to 11, representing decimal values 0 to 3. It uses two flip-flops to store the two bits, where each flip-flop represents one bit of the counter. The counter increments by one with each clock pulse, cycling through the states 00, 01, 10, and 11. This type of counter can be used in various applications, such as in digital clocks and frequency dividers.
The Java Ring, a wearable device introduced by Sun Microsystems, typically had a storage capacity of 4 MB. This capacity was used to store Java applications and user data, allowing for a range of functionalities. While 4 MB may seem minimal by today’s standards, it was sufficient for the lightweight applications intended for the device at the time of its release.
Ring counter A ring counter is a shift register (a cascade connection of flip-flops) with the output of the last one connected to the input of the first, that is, in a ring. Typically a pattern consisting of a single 1 bit is circulated, so the state repeats every N clock cycles if N flip-flops are used. It can be used as a cycle counter of N states. Johnson counter A Johnson counter (or switchtail ring counter, twisted-ring counter, walking-ring counter, or Moebius counter) is a modified ring counter, where the output from the last stage is inverted and fed back as input to the first stage. A pattern of bits equal in length to twice the length of the shift register thus circulates indefinitely. These counters find specialist applications, including those similar to the decade counter, digital to analog conversion, etc

Johnson counter is a ring counter, which is a type of counter composed of a circular shift register. Johnson counter provides many shift registers and ring counters.
