“What is the EDVAC (Electronic Discrete Variable Automatic Computer)?”
“A stored-program computer proposed by von Neumann.”
“What is the EDSAC (Electronic Delay Storage Automatic Calculator) and its significance?”
“EDSAC (Electronic Delay Storage Automatic Calculator) was the world’s first full-scale, operational, stored-program computer.”
“What is the significance of the Mark-I built at the University of Manchester in 1948?”
“A small prototype built at the University of Manchester in 1948, which might be called the first operational stored-program machine.”
“Who is John Atanasoff and what was his contribution to early computing?”
“A person who built a small-scale electronic computer in the early 1940s.”
“Who is Konrad Zuse and what did he build in Germany in the late 1930s and early 1940s?”
“A person who built a special-purpose machine in Germany in the late 1930s and early 1940s.”
“Who is Alan Turing and what was his role during World War II?”
“A person who was part of a team that built the Colossus in 1943 to decrypt intercepted German messages during World War II.”
“What was the Colossus and its purpose during World War II?”
“A special-purpose electronic computer built by a team at Bletchley Park, including Alan Turing, during World War II.”
“What did Howard Aiken build at Harvard?”

“They unveiled the PDP-8, the first commercial minicomputer.”
“What is the PDP-8 and why is it significant?”
“The first commercial minicomputer, unveiled by Digital Equipment Corporation (DEC).”
“What is a minicomputer and what was its breakthrough in design?”
“A small machine that was a breakthrough in low-cost design, allowing DEC to offer a computer for under $20,000.”
“What did Intel invent in 1971 that was groundbreaking?”
“The first microprocessor, the Intel 4004.”
“What is a supercomputer and what is it used for?”
“An extremely fast computer targeted to perform a large number of computations typically needed by scientific applications.”
