Some software programs may come to you with bugs (errors) in them. Find out what backup services are available. Is there a hotline you can call for help if the program has a problem you can't solve? Does the company provide updated versions periodically? Are they free or at nominal cost?
Compatibility with Hardware. Is the software compatible with hardware you already have, or does it run on an operating system you can use with your hardware?
Some computers use tape cassettes, like audio tape you use on a tape recorder. The most standard storage medium for programs and data is the floppy diskette, which looks like a soft phonograph record. The diskette comes in several sizes—the most common are 8 inches and 5¼ inches. A newer possibility is the 8-inch hard disk. The hard disk may be used for storage, but you buy the software on a floppy disk and transfer it.
Memory. Does your computer have enough memory to run the program?
Recommendation. Does the program come from a reputable source, or does it come with a recommendation from someone you trust?
Effectiveness. Does the program do what you want it to do correctly and consistently?
Where to Look for Good Software
Where do you find good software? Some farmers and ranchers write their own programs or pay a programmer to write a custom program. But most get existing programs either from State Extension sources or from commercial outlets.
Many operations farmers need to perform on a computer can be done by using generalized software packages readily available through commercial sources.
