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 references to 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.

Shareware is 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.

 

Comprehension check. Match the beginnings of the sentences in the first column with the endings in the second.

1. When you install software its files for different operating systems.
2. Installation procedures differ might end up in different folders.
3. Downloadable software can be provided that guides you through the installation process.
4. Public domain software involves a fee.
5. Windows software typically contains a setup program in several different formats.
6. Updating to a new version usually is not protected by copyright.

 

Vocabulary practice

1. Put the letters in the followingwords into correct order.

3. Restore the instructions for installing software from distribution media by matching the beginnings with the endings and put them into the correct order.

 

Start the license agreement if one is presented on the screen. By agreeing to the terms of the license, you can proceed with the installation.
Insert the first distribution CD or DVD. The setup program should start automatically.
Select the prompts provided by the setup program to specify a folder to hold the new software program.
Follow the installation option that best meets your needs.
Read the program you just installed to make sure it works.
Insert multiple distribution CDs in the specified drive when the setup program prompts you.

4. Fill in the gaps in the text.

When you ___ software, the new software files are placed in the appropriate ___ on your computer’s hard disk, and then your computer performs any software configurations that are necessary to make sure the program is ready to run. The ___ files and data files for the software are placed in the folder you specify. Windows software typically contains a ___ program that guides you through the installation process.

A ___ is a form of legal protection that grants the author of an original “work” the right to copy, distribute, sell, and modify that work, except under special circumstances described by laws. A software ___ is a legal contract that defines the ways in which you may use a computer program.

1. Where can I get software?

2. What is included in a typical software package?

3. How do I know if a software program will work on my computer?
