Address or A records (also known as host records) are the central records of DNS. These records link a domain to an IP address. You need A records if you want to forward your naked domain in Google Workspace.
This account is used to manage the domain, create user accounts, publish web pages, customize URLs and your domain's start page, and much more. The user(s) who have access to these accounts are called an administrator or admin. There are multiple permissions levels for administrator accounts with the highest level being called the "Super Administrator".
Archive is a Gmail feature that removes the Inbox label from a message, letting you clean up your inbox without deleting anything. It's a good idea to archive [rather than delete] messages you may wish to refer to some day. All archived messages can be found in several different ways: in the All Mail label, in any labels you've applied to them, and in Gmail's search results. When someone replies to a message you've archived, the conversation containing that message will reappear in your inbox. In legacy applications, archiving your email stores messages where they're no longer accessible.
