Understand selected software concepts

Software comes with rules about how it may be used, a numbering system that shows how it changes, and default settings that shape everyday work. Understanding these concepts, and knowing that most applications share common features, helps you use, manage and support software confidently.

A study feature written by ExamDragon, not part of the real exam. Each heading is one of Certiport's skills for this objective.

1.3.1Understand software licensing concepts

  • A licence is permission to use software under set conditions; buying software usually buys a licence, not ownership of the code.
  • A perpetual licence lets you use a version indefinitely after one payment, though updates or support may cost extra; a subscription gives access only while you keep paying.
  • Freeware costs nothing but its code is usually closed; trial software works for a limited time or with limited features.
  • Open source licences let anyone view, change and share the code; permissive licences (such as MIT or Apache) allow wide reuse, while copyleft licences (such as the GPL) require shared changes to stay under the same licence.
  • The end-user licence agreement (EULA) sets the terms: how many devices or users, whether it can be transferred, and what is forbidden.
  • Licences can be per user, per device, or for a whole organisation (volume or site licence).

Example: A school buys a site licence for an office suite so every staff computer can use it, while a student uses a free open source image editor at home.

1.3.2Understand software versioning concepts

  • Many programs number versions as major.minor.patch, for example 4.2.1.
  • A major number change can bring big changes and may break compatibility with older files, plug-ins or workflows.
  • A minor number change usually adds features while staying compatible; a patch fixes bugs or security problems.
  • Release notes or a change log explain what is new, fixed or removed in each version.
  • Older versions eventually reach end of support and stop receiving security updates.

Example: An app updates from 3.4.2 to 3.4.3 overnight to fix a crash, but IT tests the move to 4.0.0 first because it changes the file format.

1.3.3Identify processes for setting software defaults

  • Defaults are the settings a program uses until you change them, such as the save location, font, theme or language.
  • The operating system decides which app opens each file type and which browser or email app is the default.
  • Change defaults in the app's Settings or Options, or in the operating system's default apps settings.
  • Templates store default formatting for new documents, so changes apply to every new file.
  • In organisations, IT may set defaults centrally through policies; a 'reset to defaults' option undoes personal changes.

Example: A user sets PDF files to open in a preferred reader and changes the word processor's default font and save folder so every new document starts the same way.

1.3.4Explain how to use common features across similar applications

  • Most applications place File, Edit, View and Help functions in similar menus or ribbons.
  • Common shortcuts work across many programs: Ctrl or Cmd with C (copy), V (paste), X (cut), Z (undo), S (save), F (find) and P (print).
  • Right-click or long-press usually opens a context menu with actions for the selected item.
  • Save As and Export create a copy in another name, place or format; Share sends a link or copy to others.
  • When you meet a new app, look for the same patterns first and use the built-in help or search box.

Example: A user who knows a word processor opens an unfamiliar presentation app and immediately finds undo, find and replace, and export to PDF in the expected places.

Key terms

Perpetual licence
A licence bought once that allows a version of software to be used indefinitely.
Subscription
A licence that gives access to software for as long as regular payments continue.
Open source
Software whose source code is published under a licence that allows viewing, changing and sharing.
EULA
End-user licence agreement: the legal terms a user accepts to use software.
Patch
A small update that fixes bugs or security weaknesses.
Default
A setting a program uses automatically unless the user changes it.

Easy to confuse

  • Free to download does not mean free to use for any purpose; the licence may limit commercial use.
  • Open source does not always mean free of conditions; many open source licences require credit or sharing changes.
  • A higher major version is not automatically safe to install on a work system; check compatibility first.
  • Cancelling a subscription usually removes access, unlike a perpetual licence.

After this guide: You can explain common licence types and version numbers, change defaults and transfer skills between similar apps.
