Addressing refers to the method of identifying and locating a specific destination or recipient. In the context of mailing, it involves writing the recipient's name, street address, city, state, and postal code on an envelope or package. This ensures that the item reaches the correct location efficiently. In computer networking, addressing is the process of assigning unique identifiers to devices, such as IP addresses for computers. This allows devices to communicate with each other over the internet or a local network. Proper addressing is essential for data transmission and network management.
