Answer: EDSAC
| Computer | Year | Developer(s) | Description |
| Electronic Delay Storage Automatic Calculator (EDSAC) | 1949 | Maurice Wilkes and his team at the University of Cambridge | The EDSAC was one of the first practical stored-program computers and played a significant role in early computing history. |
| ENIAC (Electronic Numerical Integrator and Computer) | 1945 | John W. Mauchly and J. Presper Eckert | Often considered one of the earliest electronic general-purpose computers, ENIAC could be reprogrammed for different tasks, but it used a plugboard and switches for programming. |
| Manchester Mark I (Baby) | 1948 | Frederic C. Williams, Tom Kilburn | One of the earliest computers to execute stored programs. It used a Williams-Kilburn tube for memory. |
| UNIVAC I (Universal Automatic Computer) | 1951 | J. Presper Eckert and John Mauchly | The UNIVAC I was one of the first commercially produced computers to use the stored program concept. |
| Ferranti Mark I | 1951 | Ferranti and J. Lyons | Developed in the United Kingdom, it was one of the first computers to be based on the von Neumann architecture. |
| IBM 701 (Defense Calculator) | 1952 | IBM | IBM’s first stored-program computer, designed for scientific and engineering calculations. |
