Analytical Engine</h2>
Explanation:
Analytical Engine, generally considered the first computer, designed and partly built by the English inventor Charles Babbage in the 19th century (he worked on it until his death in 1871).
Answer:
CPU.
Explanation:
A processor, also known as a Central Processing Unit, is a piece of hardware in a computer that performs basic operations and control when executing program code.
Processors are usually made as integrated circuits closed in a hermetic casing, often with gold-plated leads (used for resistance to oxidation) and in this form they are called microprocessors - in common speech the terms processor and microprocessor are used interchangeably. The heart of the processor is a single crystal of silicon, on which a series of semiconductor layers have been applied by means of photolithography, forming, depending on the application, a network of several thousand to several billion transistors. Its circuits are made of metals with good electrical conductivity, such as aluminum and copper.
