He used the term in relation to issues with a robot in a short story entitled, "Catch That Rabbit". This was later included in his seminal collection of short stores I, Robot.
In the story, he wrote, "U. Robots had to get the bugs out of the multiple robots, and there were plenty of bugs, and there are always at least half a dozen bugs left for the field-testing. According to the ACM's digital library , the term bug also appears in three papers from Interestingly the term "debug" also predates the computer age. Some sources make mention of the term being used in relation to the testing of airplane engines during the Second World War.
By the terms "bug" and "debugging" were in common enough use to be mentioned in the Compatible Time-Sharing System CTSS manually without any apparent attempt to explain their meaning.
Although this is a common question, it is a bit misleading. Glossing over the early past use of the term in engineering jargon which predated the electronic computer in any case the first real computer bug wasn't actually named per se. Famously, the very first instance of a computer "bug" was recorded at pm on the 9th of September This "bug" which a two-inch wingspan 5 cm was preserved behind a piece of adhesive tape on the machines' logbook with the now immortalized phrase "[The] First actual case of a bug being found".
The cause of the bug's appearance appears to have been down to members of the programming teams' late-night shift, which included the pioneering computer scientist, and former U.
Navy Rear Admiral Grace Hopper. A team member left the windows of the room open at night. This was more than enough to let in the moth, which was attracted by the lights in the room and the heat of the calculator to nestle in the 'gubbins' of the Mark II Harvard, where it met its unfortunate end. Moths and other insects tend to exhibit a behavior called transverse orientation.
This is the way in which they tend to navigate by flying at relative angles to a distant light source.
For millions of years, this strategy served nocturnal insects well by allowing them to navigate by the light of the Moon. Of course, with the advent of electricity and artificial lighting, they often become confused. On the 9th of September , Hopper traced an error on the Mark II to a dead 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.
While it is certain that the Harvard Mark II operators did not coin the term 'bug', it has been suggested that the incident contributed to the widespread use and acceptance of the term within the computer software lexicon.
Henceforth the term "bug" entered more general use as a way to describe any errors or glitches in a program. However, as Hopper often mentioned, she neither coined the phrase nor found the insect in question herself. That was down to the other engineers on the team. Bill and his colleagues were clearly well versed in the meaning of the term and Hopper would later take great pleasure in recalling the story.
While a computer bug is usually some form of a coding error, people sometimes confuse bugs with the form of malicious software like viruses or other malware. Finding out your computer has been infected with a virus can be a nightmare for most computer users. They are not only annoying to deal with but can be time-consuming to remove completely from your computer, not to mention potentially dangerous with regards to your personal or financial information.
For this reason, it is vital that you at least have some antivirus and spyware programs installed on your computer. It is also incredibly important that you keep them up to date and ensure they are set to routinely, and automatically, scan your files for potential threats.
Bugs, in contrast, are errors in code and do not tend to be transmitted from one computer to the next, in the same way as a virus. Most bugs come from mistakes made in either the program's design or source code, or by the use of incorrect code. She never called it a bug. Thomas Edison did. In in a letter to his partner, he wrote about an error in his machine — the quadruplex telegraph system — calling this malfunction a bug.
Later on, he continued to use this exact word whenever he found a flaw in the design or operation of his technical system. Soon other members of the electrical community started using it in the same context.
It became quite popular among technical inventors and in it was included in the Standard Electrical Dictionary. Experts assure us that a computer bug is not a form of malicious software like viruses or other malware.
It is rather a coding error, that cannot be transmitted from one computer to another. The Y2K bug is probably one of the most notorious bugs.
