FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The Electronic Numerical Integrator and Computer, also known as the ENIAC, was the first computer that would use the vacuum tube.

Detailed explanation-2: -First Generation: Vacuum Tubes (1940–1956) The first computer systems used vacuum tubes for circuitry and magnetic drums for main memory, and they were often enormous, taking up entire rooms.

Detailed explanation-3: -First Computers ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers. ENIAC was also the first machine to use more than 2, 000 vacuum tubes, using nearly 18, 000 vacuum tubes.
