The Transistor is Invented
The Transistor made it possible for computers to become much smaller, put off less heat, use less power, and become cheaper. -
First Stored Program Electronic Computer
EDSAC short for Electronic Delay Storage Automatic Calculator was an early British computer considered to be the first stored program electronic computer that was created at the University of Cambridge in England. The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game, nicknamed "Baby". -
