When did Grace Hopper discover the bug?
September 9th, 1947
Discovering a moth
On September 9th, 1947, Grace Hopper found the first actual computer bug. A moth was stuck between relays of the Harvard Mark II computer, and she documented this finding in her log book.
Who invented the term bug?
A typical version of the story is: In 1946, when Hopper was released from active duty, she joined the Harvard Faculty at the Computation Laboratory where she continued her work on the Mark II and Mark III. Operators traced an error in the Mark II to a moth trapped in a relay, coining the term bug.
Who developed the first compiler in the years 1951 1952?
The first practical compiler was written by Corrado Böhm, in 1951, for his PhD thesis. The first implemented compiler was written by Grace Hopper, who also coined the term “compiler”, referring to her A-0 system which functioned as a loader or linker, not the modern notion of a compiler.

Where did computer bug originate?
Probably because in 1947, a computer programmer Grace Hopper and her team found a bug – a real moth, lying in a relay of Harvard University’s Mark II electromechanical computer. The moth was found on a piece of tape on the machine’s logbook.
When was the word bug coined?
As Alexander Magoun and Paul Israel explain in an article earlier this year in the newspaper of the Institute of Electrical and Electronics Engineers, “bug” appeared in Edison’s notebooks as early as 1876 to describe problems in his systems.
When was the term computer bug first used and why?
On the 9th of September 1947, Hopper traced an error on the Mark II to a deceased moth that was trapped in a relay. The insect was carefully removed and taped to the logbook, and the term computer bug was used to describe the incident.
What was the first bug on earth?
The oldest confirmed insect fossil is that of a wingless, silverfish-like creature that lived about 385 million years ago. It’s not until about 60 million years later, during a period of the Earth’s history known as the Pennsylvanian, that insect fossils become abundant.
What is the origin of the term bug?
Q: Where did the word “bug” originate? A: It is from an old Welsh word, bwg (pronounced boog), which means evil spirit or hobgoblin and may also be the origin of boogeyman, the imaginary creature that haunts little children. The first bug was probably the bedbug, since it terrorized folks at night by feeding on them.
When was the first computer invented and by who?
The first computer that resembled the modern machines we see today was invented by Charles Babbage between 1833 and 1871. He developed a device, the analytical engine, and worked on it for nearly 40 years.
Where was the first insect found?
The oldest definitive insect fossil is the Devonian Rhyniognatha hirsti, from the 396 million year old Rhynie chert. It may have superficially resembled a modern-day silverfish insect.
When did first insects appear?
479 million years ago
A new timeline for insects shows that the creatures first evolved 479 million years ago — earlier than previously suspected — and that their appearance coincided with Earth’s first land plants.
When was the first insect discovered?
about 412 million years ago
Fossil evidence suggests that the first insects lived about 412 million years ago, during the Early Devonian Period. But the researchers’ phylogenetic data indicates that the largest group of insects, hexapoda, may have evolved even earlier, around 479 million years ago, during the Early Ordovician Period.
How old is the oldest living bug?
The Longest-lived Insect: The queen of termites, known to live for 50 years. Some scientists believe that they live for 100 years. The Oldest Fossil Butterfly or Moth: A Lepidoptera fossil found in England is estimated to be 190 million years old.
Which came first insects or fish?
The first invertebrates developed in the oceans. They were soft-bodied animals with a shell or carapace, such as these trilobites. Fish, like the agnathans, appeared. They were the first vertebrates, which are animals that have a spinal column.
When did insect evolve?
around 480 million years ago
Insects evolved at the same time as the earliest land plants around 480 million years ago, an international study has revealed. The earliest fossil evidence for insects is dated at around 400 million years old, but the new study uses genetic techniques to corroborate estimates that they evolved much earlier.
