To date we use many electric devices that was not exist before normally. One of these devices is computer. It’s also called PC (Personal Computer) and machine by professionals. Basically, computer is a group of instruments. In this group there are many devices and instruments CPU, LED, keyboard and Mouse.

We will talk about mouse which is the basic tool to use computer. Mouse or Computer Mouse is a pointing machine that detects tow-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface.

Old days computer mouse

The first public manifestation of a mouse controlling a computer system was in 1968. Originally wired to a computer, many modern mice are cordless, relying on short-range radio communication with the connected system. Mice originally used a ball rolling on a surface to detect motion, but modern mice often have optical sensors that have no moving parts. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as selection of a menu item on a display. Mice often also feature other elements, such as touch surfaces and “wheels”, which enable additional control and dimensional input.

Douglas C. Engelbert

The first computer mouse was invented by Douglas C. Engelbert. He invented the computer mouse in 1964 — two decades before it would ship with the first Apple Macintosh. The idea occurred to him when attending a computer graphics conference, and he was brainstorming ways to move an onscreen cursor.

Old mouse was slow and dim with limited controls. It had a large shape with big and weird wheel. It needed a plane surface to work. It had been a little bit heavy. So it was not so easy to handle it. Gradually it was developed and now it has a smart shape with various features. To date, with a mouse you have more control than the old time. Now you can even navigate with mouse.
So, it was not so easy to handle it. Gradually it developed and now it has a smart shape with various features. To date, with a mouse you have more control than the old time. Now you can even navigate with mouse. More control on cursor while selecting any thing or painting. It made so easy to design and illustrate any thing with your finger tips.
