BUYING AND INSTALLING SOFTWARE

It’s surprising how quickly your collection of software can grow as you discover new ways to use your computer. Before you can use software, you have to install it on your computer.

The key “ingredients” necessary to install new software are the files that contain the programs and data. These files might be supplied on distribution media. System requirements, which specify the operating system and minimum hardware capacities necessary for a software product to work correctly can be found on the software box or posted on the download site.

Installation basics

When you install software, the new software files are placed in the appropriate folders on your computer’s hard disk, and then your computer performs any software or hardware configurations necessary to make sure the program is ready to run. During the installation process, your computer usually performs the following tasks:

- Copies files from distribution media or downloads files to specified folders on the hard disk

- Uncompresses files that have been distributed in compressed format.

- Analyzes the computer’s resources, such as processor speed. RAM capacity, and hard disk capacity, to verify that they meet or exceed the minimum system requirements.

- Analyzes hardware components and peripheral devices to select appropriate device drivers.

- Looks for any system files and players, such as Internet Explorer or Windows media Player, that are required to run the program but are not supplied on the distribution media or download.

- Updates necessary system files, such as the Windows Registry and the Windows Start menu, with information about the new software.

Software updates

Software publishers regularly update their software to add new features, fix bugs, and update its security. Types of software updates (also called “upgrades”), include new versions, patches, and service packs. A software patch is a small selection of program code that replaces part of the software you currently have installed. The term service pack, which usually applies to operating system updates, is a set of patches that correct problems and address security vulnerabilities. Software patches and service packs are usually free. It’s always a good idea to install patches and services when they become available. The revised code they contain often addresses security vulnerabilities and the sooner you patch up those holes, the better. A new version update usually installs in a similar way as you installed the original version, by activating a setup program, displaying a license agreement, and adding updated entries to your computer’s Start menu. Patches and service packs are usually distributed over the Internet and automatically install themselves when you download them. To combat piracy, many software publishers require users to type in a validation code to complete an installation. The result of an update depends on several factors. Most patches and service pack installations can not be reversed. A new version installation typically overwrites the old version, but you might have the option to keep the old version just in case you have trouble with the new one and need to revert back to the previous version.

Uninstalling software

With some operating systems, such as DOS, you can remove software simply by deleting its files. Other operating systems, such as Windows and Mac OS, include an uninstall routine, which deletes the software’s files from various folders on your computer’s hard disk. The uninstall routine also removes referencesto the program from the desktop and from operating system files, such as the file system restrictions.

Software Copyrights and licenses

Copyright laws have fairly severe restrictions on copying, distributing, and reselling software; however, a license agreement might offer additional rights to consumers. The licenses for commercial software, shareware, freeware, open source, and public domain software specify different levels of permission for software use, copying, and distribution.

Commercial software is typically sold in computer stores or at Web sites. Although you “buy” this software, you actually purchase only the right to use it under the terms of the software license.

Sharewareis copyrighted software marketed under a “try before buy” policy. It typically includes a license that permits you to use software for a trial period. To use it beyond the trial period you must pay a registration fee. A shareware license usually allows you to make copies of the software and distribute them to others. If they choose to use the software, they must pay a registration fee as well.

Freeware is copyrighted software that is available for free. Because the software is protected by copyright, you cannot do anything with it that is not allowed by copyright law or by the author. Typically, the license for freeware permits you to use the software, copy it, and give it away, but does not permit you to alter it or sell it. Many utility programs, device drivers, and some games are available as freeware.

Open source software makes the uncompiled program instructions – the source code – available to programmers who want to modify and improve the software.

Public domain software is not protected by copyright because the copyright has expired, or the author has placed the program in the public domain, making it available without restriction. It may be freely copied, distributed, even resold. The primary restriction on public domain software is that you are not allowed to apply for a copyright on it.

Software Piracy

Software is easy to steal. You don’t have to walk out of a store with a $495 DVD Workshop software box under your shirt. You can simply borrow your friend’s DVD Workshop distribution CDs and install a copy of the program on your computer’s hard disk. It seems so simple that it couldn’t be illegal. But it is.

Piracy takes many forms. End-user piracy includes friends loaning distribution disks to each other and installing software on more computers than the license allows. Although it is perfectly legal to lend a physical object, such as a sweater, to a friend, it is not legal to lend digital copies of software and music because, unlike a sweater that can be worn by only one person at a time, copies of digital things can be simultaneously used by many people.

Counterfeiting is the large-scale illegal duplication of software distribution media, and sometimes even its packaging. According to Microsoft, many software counterfeiting groups are linked to organized crime and money-laundering schemes that fund a diverse collection of illegal activities, such as smuggling, gambling, extortion. Counterfeiting software is sold in retail stores and through online auctions– often the packaging looks so authentic that buyers have no idea they have purchased illegal goods.

Internet piracy uses the Web as a way to illegally distribute unauthorized software. The Business Software Alliance (BSA) estimates that more than 800.000 Web sites illegally sell or distribute software.

In many countries software pirates are subject to civil lawsuits for monetary damages and criminal prosecution, which can result in jail time and stiff fines. Is software piracy really damaging? Who cares if you use a program without paying for it? Software piracy is damaging because it has a negative effect on the economy. Software production fuels economic development of many countries. A BSA economic impact study concluded that lowering global piracy from an average of 36 % to only 26 % would add more than 1 million jobs and $400 billion in worldwide economic growth.

Decreases in software revenues can have a direct effect on consumers, too. When software publishers are forced to cut corners, they tend to reduce customer service and technical support. As a result, you, the consumer, get put on hold when you call for technical support, find fewer free support sites, and encounter customer support personnel who are only moderately knowledgeable about their products. The bottom line – software piracy negatively affects customer service. As an alternative to cutting support costs, some software publishers might build the cost of software piracy into the price of the software.

Some analysts suggest that people need more education about software copyrights and the economic implications of piracy. Other analysts believe that copyright enforcement must be increased by implementing more vigorous efforts to identify and prosecute pirates.
