True. She retired as a rear admiral in 1986 at age 79—the oldest serving officer in the Navy at that time.

Question 3

True or false: Grace Hopper invented the first compiler, which allowed programmers to write code using symbolic instructions instead of machine language.

Accepted Answer

True. She created the A-0 compiler in 1952, translating symbolic mathematical code into machine code, a foundational concept for modern compilers.

Question 4

True or false: Grace Hopper attained the rank of rear admiral in the United States Navy.

True. Grace Hopper served in the U.S. Navy from 1943 until 1986, retiring as a rear admiral. She was one of the first women to reach that rank.

Question 5

True or false: Grace Hopper was denied a patent for her compiler because the U.S. Navy considered it a military secret.

Accepted Answer

False. No patent denial occurred. Hopper never patented the compiler; it was developed at Remington Rand, which owned the rights.

Question 6

True or false: The term 'computer bug' existed before Grace Hopper found a moth in a relay.

Accepted Answer

True. Engineers used 'bug' for mechanical glitches since the 1800s. Hopper's famous moth find just popularized the term for software errors.

Question 7

True or false: Hopper coined the term 'nanosecond' by cutting a piece of wire to the length light travels in one billionth of a second.

Accepted Answer

False. She famously handed out 11.8-inch wires to illustrate a nanosecond, but she didn't coin the term—it was already in scientific use.

Question 8

True or false: Grace Hopper was initially rejected from the Navy because she was too thin to meet weight requirements.

Accepted Answer

True. She was under the 120-pound minimum by 15 pounds when she first tried to join the WAVES in 1943, alongside age restrictions. She later obtained a waiver.
