Three Basic Categories of Application Software Stand-alone programs Integrated software Office Suites These programs differ in their features and in cost You should choose the type of software that best fits your needs, computers, and budgets.

Integrated Software Combine the basic features of several applications into one package. Not as powerful or as complete as stand- alones. Do not specialize in one application. Usually is less costly and fairly easy to use Popular integrated programs –AppleWorks –Microsoft Works

Office Suites A package of stand-alone programs that can be used independently of one another. Allows the user to move data effectively among the programs. More popular with users than integrated programs because they offer more features and advanced functionality.

Which Software is Right for You? Type of application software you choose depends on the following: –What you want it to do –How much you are willing to spend –How easy the programs are to learn –Whether the software will work on your computer –How much space each program will take up on your hard drive

Minimum System Requirements Each computer must meet the minimum hardware and software needs of the program for it to work properly. It is important to choose software that will work with the following: –Your type of computer (Mac or PC Compatible) –Microprocessor speed –Operating system ( such as Linux, Mac OS X, or Windows Vista) –Available amount of memory (RAM) –Available hard drive space –Special equipment, such as a modem or CD-ROM drive

How Software is Acquired Some application software may be loaded on a new computer. Some additional ways software may be obtained are: –Commercial Software—copyrighted software that you must buy before using it. –Custom Software—must be developed by professional programmers, but it is tailored to the user’s exact specifications.

Shareware Copyrighted software that you can use on a try- before-you-buy basis. Most is downloaded over the Internet and you use the program at no charge for a specified time period. If you decide to keep using if after that, you must pay a registration fee to the company. You are also allowed to copy shareware and give it to your friends. They must follow the same process to acquire the software.

Freeware Application software that is distributed without cost. Freeware programs have been copyrighted by their developers and made available to the public without charge. The developers allow users to install the program as long as they do not resell it to other people.

Public Domain Software Program authors allow you to use programs, share them, give them away, or even alter them to meet certain needs. The quality of these programs can vary widely. They may contain more errors than other types of software.

Installing and Uninstalling Programs Application software must be installed, or prepared to run on a computer, before it can be used. You must copy it from a location (disk, CD, Internet) to the computer’s hard drive. Most programs come with an installation, or setup, program that prompts you to load the software onto the computer. Many programs also have a special code that must be entered to proceed with installation. To delete a program from the computer, you must run a special removal program to properly uninstall it.

Using Software Legally Buying copyrighted software usually permits the buyer to install and use that software on only one computer. –This permission is contained in a document known as the software license. –Users agree to the terms of the license during the installation process. For schools and businesses that plan to install the software on several computers, they must purchase a site license for a specific number of computers to use the software.

Software Piracy People who copy copyrighted software to install on other computers, give away, or sell are guilty of copyright violation and stealing, called software piracy. Violating a copyright and pirating software are both morally wrong and illegal. These activities discourage the authors of good software from writing new and better programs because they may not get paid for their work. Pirated software cannot be registered, so users do not get the support services they may need.
