An 8-bit microprocessor is a type of central processing unit (CPU) that processes data in 8-bit chunks. This means it can handle 256 different values at a time, which is suitable for simple computing tasks. These microprocessors are often used in basic electronic devices, such as calculators and early personal computers. Introduced in the late 1970s, popular examples of 8-bit microprocessors include the Intel 8080 and the Zilog Z80. They played a crucial role in the development of computing technology, laying the groundwork for more advanced processors. Despite their limitations, they are still appreciated for their simplicity and efficiency in specific applications.
