What does the term "classical computer" refer to?
A. an early computer built before the 1950s
B. a computer that operates using conventional bits
C. a computer that is not connected to the internet
D. a computer modified to perform quantum functions
Answer: The term "classical computer" refers to a computer that operates using conventional bits.
So correct answer is option B.
Classical computers are the type of computers that have been in use since the mid-20th century, and they are still widely used today. These computers process and store information using bits, which can have a value of either 0 or 1. The bits are processed using logical operations such as AND, OR, and NOT, which allow classical computers to perform calculations and execute programs.
In contrast, quantum computers are a type of computer that use qubits (quantum bits) to process and store information. Unlike classical bits, qubits can have a value of 0, 1, or both at the same time, which allows quantum computers to perform multiple calculations simultaneously and solve certain types of problems much faster than classical computers.
Therefore, the term "classical computer" is used to distinguish the conventional computing technology that uses classical bits from the emerging quantum computing technology that uses qubits.
