Abbreviations and acronyms

Use abbreviations that users are familiar with, and write out uncommon abbreviations. Only use an abbreviation that has already been established and never make up an abbreviation or acronym yourself to help keep consistency in your products. Make sure that your abbreviations are consistent, always abbreviate units of measurement, and, when referring to a product, default to how the company refers to it themselves.

Abbreviation
Usage
CSS
Stands for Cascading Style Sheets. Write CSS in all caps.
e.g., i.e., and etc.
Use sparingly. These terms aren’t easily understood by everyone, especially users whose native language is not rooted in Latin. Write out their meaning instead:
  • e.g. - for example
  • i.e. – in other words
  • etc. – and more/so on
HTML
Stands for Hypertext Markup Language. Write HTML in all caps.
JS
Stands for JavaScript. Write JS in all caps.
K8
Stands for Kubernetes.
KVM
Refers to a kernel-based virtual machine. Write KVM in all caps.
sysadmin
Avoid using abbreviations like sysadmin and SysAdmin because they’re too informal and not always easily understood. System should be singular (not Systems administrator) because it can include both a single system and multiple systems, similar to a brain surgeon, who works on more than one brain.

U.S.
As a noun, use United States unless there are space constraints. As an adjective, use U.S. (for example, U.S. soldier). As part of an organization, use U.S.

URL
Stands for Uniform Resource Locator. Write URL in all caps.
VM
Refers to a virtual machine. OK to abbreviate as long as you've spelled it out once in the first occurrence and as long as VM won't be confused with other terms that share that acronym.

Taken from Red Hat Corporate Style Guide.
N/A
Refers to data not applicable, meaning there is no relevant, matching, or applicable data.

For example, when a filter returns no results, when a data source is empty, or when no data source is connected.
--
Refers to data unavailable, meaning the data exists and fits the criteria, but is not currently available to display.

For example, when a data source is connected, but data can't be fetched due to permission restrictions or errors.
