Q & A

What was the key feature of Irma that allowed it to be read by machines?

Irma had magnetic characters printed on it, which allowed it to be read automatically by machines.

How did Irma's introduction affect the speed of banking operations?

Irma was more than 100 times faster than the best human bookkeeper and virtually error-free, significantly increasing the speed of banking operations.

What were some of the new jobs created in the bank due to Irma?

New jobs created included handling reports from Irma centers and preparing work for Irma centers, which were less tedious than bookkeeping.

Why were valves important during the 1950s?

Valves were important because they were the main component that made computers possible, and computers consumed valves as fast as they could be manufactured.

What was the significance of the transistor for computer technology?

The transistor was a tiny electronic component that could replace the vacuum tube as the main switching element in a computer circuit, making computers smaller, lighter, and more efficient.

Who were the inventors of the transistor and what recognition did they receive?

The inventors of the transistor were Walter Brattain, John Bardeen, and William Shockley, who won the Nobel Prize in 1956.

What problem did the integrated circuit solve in computer manufacturing?

The integrated circuit solved the 'tyranny of numbers' problem by eliminating the need to hand wire large numbers of electronic components together.

What was the role of the integrated circuit in the Apollo 11 mission?

The onboard computer for the Apollo 11 mission, which was built from integrated circuits, was crucial for maneuvering the spacecraft into orbit and was the smallest computer in the world at the time.

How did the integrated circuit impact the electronics industry and its cost?

The integrated circuit allowed for mass production, which led to a significant decrease in cost and an increase in performance, reliability, and miniaturization of electronics.

What was the nickname given to the region in California that became the center of the electronics industry?

The region in California that became the center of the electronics industry was aptly named Silicon Valley.

What was the ultimate test of the integrated circuit's reliability as described in the script?

The ultimate test of the integrated circuit's reliability was during the Apollo 11 mission when the spacecraft lost contact with Mission Control and relied on the onboard computer to maneuver into orbit.
