What is the .IN3 File Extension?

.IN3 File Extension Description:

The IN3 file extension is simply the input device driver for the Harvard Graphics application.

Harvard Graphics is a pioneer in presentation programs, created by Software Publishing Corporation. This was developed primarily for the MS-DOS and Microsoft Windows. This software is among the earliest presentation consumer application software that permit the user to incorporate different information graphics, texts, and charts, and turn them a customized slideshow presentation, just like those created in the Microsoft PowerPoint. However, working with this application needs the use of some input devices, and this can only be achieved with the IN3 file extension.

The IN3 file extension is a computer program that allows the input devices to interact with the software, more particularly the Harvard Graphics. This file extension is also involved with the different input devices like keyboards, mouse, or any device or piece of hardware tools used for inputting data. These are primarily used to provide control signals and data to the computer. This way, the IN3 file extension can make it possible for the Harvard Graphics and the different input devices, to communicate and work well with one another.

Commonly, files like those with the IN3 file extension communicates with the hardware using the computer bus, or what is called as communications subsystem, to where the hardware is already connected. Whenever the Harvard Graphics call or needs to invoke a routine in the driver, the IN3 file extension will order commands to the device. When that hardware device sends back information to the file extension, the IN3 file extension will also invoke a routine to the original calling program.

There will be no problem with communications between the hardware and the software, since device drivers like the IN3 file extension are hardware-dependent; however, they are also specific with the operating system. Through the IN3 file extension, users can work more efficiently with the Harvard Graphics, since inputting information to the program will be very easy and trouble-free.
