Who Invented the First Computer Mouse and How Did It Get Its Name
The first computer mouse was given its name by the device’s inventor, Douglas Engelbart.
Because, for some reason, the “X-Y Position Indicator for a Display System” just didn’t catch on.
The first users hated the clumsiness of the name and quickly dubbed them “turtles,” which eventually became “rodent,” which morphed into the cuter-sounding “mouse.”
This name was just right for the shape and size of the X-Y Position Indicator, and it stuck.
These days, mice are sophisticated devices that have many buttons. Some are cordless, and more recently, have no balls for tracking. Instead, a low power laser is used to track the surface it sits on.
The advantage? We no longer have to remove the ball from the poor mouse and clean the rollers so our mouse works like new again.
What Was Considered a Computer Before the Electronic Age and How Much Did It Cost
The word computer first appeared in the seventeenth century as the job title of a person who did calculations as an occupation.
Most human computers weren’t paid very much, just like the Information Technology workers of today, even though their job descriptions are slightly different.
Although slide rules were sometimes called computers, it wasn’t until the 1940s, with the development of massive electronic data machines, that the human occupation of computing became obsolete.
These mechanical devices became known as computers.
