Detailed explanation-1: -(1919-1995) in order to design of the ENIAC (Electronic Numerical Integrator and Computer). For temporary calculations, it contained twenty 10-digit registers, and its size was around 30.5 meters (100 feet) long.
Detailed explanation-2: -A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. Although superseded by second-generation transistorized computers, vacuum-tube computers continued to be built into the 1960s. These computers were mostly one-of-a-kind designs.
Detailed explanation-3: -The first generation computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. The vacuum tube was developed by Lee DeForest. A vacuum tube is a device generally used to amplify a signal by controlling the movement of electrons in an evacuated space.
