Suffixes in Salesforce

In Salesforce, a suffix is a word or a set of characters that are added to the end of metadata to identify it. For example, in a custom field name, a suffix like “__c” is often used to denote a custom field created by the user, while standard fields might not have any suffix. In a developer context, suffixes in Apex class names or Visualforce pages can help identify the purpose or usage of the code.
