Final answer:
All data in a traditional computer is represented in binary code, which has two states, 0 and 1. Quantum computers use qubits, which can represent mixed states of 0 and 1 simultaneously. Binary representation in digital computers is crucial for clear and efficient data transmission.
Step-by-step explanation:
All data and instructions inside a computer are represented in binary code, which means there are only two states. In digital electronics, this is most often represented as the numbers 0 and 1. Each of these binary digits is known as a bit.
In contrast to classical binary digital computers, a quantum computer uses quantum bits, or qubits. A qubit can be in a mixed state where it represents a combination of 0 and 1 at the same time, which is fundamentally different from the strictly two-state binary system of traditional computers.
The classic binary digital representation is incredibly efficient for digital data transmission, such as cell phone conversations or computer data, because binary data can be transmitted clearly even when signals are weak, and can be compressed using algorithms to transmit more data efficiently.
