Text D: Buying and installing software

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 that are necessary to make sure the program is ready to run. The executablefiles and data files for the software are placed in the folder you specify. Some supportprograms for the software, however, might be stored in different folders, such as Windows/ System. Windows software typically contains a setup program that guides you through the installation process.

To install application software from a distributionCD, simply place the CD in the drive and wait for the setup program to begin. The installation process is slightly different for application software that you download. Usually all the files needed for the new software are consolidated into one large file, which is compressed to decrease its size and reduce the download time. This large, downloaded file must be reconstituted, or unzipped, into the original collection of files as a step in the installation process. A self-installing executablefile automatically unzips the downloaded file and starts the setup program. A self-executing zip file automatically unzips the software’s files, but does not automatically start the set up program.

Free software updates include new versions, patches, and service packs that contain code to fix bugs and security vulnerabilities. Some updates require a validation code.

A copyright 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 copyright laws. A software license is a legal contract that defines the ways in which you may use a computer program. Licenses for commercial, shareware, freeware, open source, and public domain software provide consumers with different sets of rights pertaining to copying and distribution.

Agree or disagree with the following statements.

1. The files for downloaded software are usually zipped into one large compressed file.

2. System requirements specify the operating system and minimum hardware capacities required for software to work correctly.

3. Linux is an example of freeware.

4. Shareware is not copyrighted, making it available for use without restriction.

5. A software patch is a small collection of program code that replaces part of the software you currently have installed.
