Tölvupóstfang

Tölvupóstfang, commonly referred to as an email address, is a unique identifier used for sending and receiving electronic mail messages. It is composed of two main parts separated by the "@" symbol. The part before the "@" symbol, known as the local-part, typically represents the username or mailbox name of an individual or entity. The part after the "@" symbol, known as the domain, specifies the mail server or network where the mailbox is located.

The structure of a tölvupóstfang is standardized to ensure that email can be routed correctly across the internet. For example, in an address like "notandi@dæmi.is", "notandi" is the local-part and "dæmi.is" is the domain. The domain part often includes a top-level domain (TLD) such as ".com", ".org", or country-specific TLDs like ".is" for Iceland.

Email addresses are fundamental to modern communication, enabling individuals and organizations to exchange information digitally. They are used for personal correspondence, business communications, online registrations, and a wide range of other digital interactions. The creation and management of tölvupóstfang are typically handled by email service providers, which assign these addresses to their users.
