It was official today in 1970 that a mouse can make it easier to work on a computer. American engineer Douglas Engelbert recieved patent for his X-Y indicator for a display system, more commonly known as a mouse.
Engelbert called it a mouse because of it’s shape and it’s cord which looked like a tail. Although the mouse has lost its tail now and is now wireless.
The mouse was first prototyped in 1964, but wasn’t demoed till 1968 and was not included in a commercial computer till 1981.
Apple first brought the mouse to a personal computer with the Lisa in 1983. However the mouse did not become ubiquitous until after 1984, when Apple’s Macintosh popularized the device.
1970 में आज ही के दिन अमेरिकी engineer और आविष्कारक डगलस एंजेलबर्ट को computer mouse के लिए patent मिला था। डगलस ने इस device का नाम इसके आकार की वजह से Mouse रखा था। कंप्यूटर्स की दुनिया में ये एक बहुत बड़ी क्रांति साबित हुई।
