Full Form of ZIP Code:
Zone Improvement Plan
ZIP Code Full Form is Zone Improvement Plan. ZIP is a postal program that helps to identify each postal zone by a unique number called ZIP Code allotted to it. Simply and typically, it is a mail coding system used by the USPS (United States Postal Services). This program was initiated back in 1963. ZIP ensures that mails can travel one postal zone to the other without any hassle or difficulty. That’s why ZIP code is used. Mailers write the ZIP code in the postal address and quick transfer of the mail is done accordingly. The system of ZIP replaced PDZS (Postal Delivery Zone System) because it is more efficient and time-friendly. ZIP emphasizes on the improved efficiency and accuracy of mail sorting and its delivery. Unique, post-office box only, military, and standard are the four variants of ZIP.
A ZIP code is a combination of five decimal numerical digits. The first digit represents a certain geographical group of United States, the second and third digits are used to collectively represent a specific region within that group, and the fourth and fifth digits denote a specific area of delivery address within that region. However, a ZIP+4 code is an extended version. Along with the commonly used combination of five digits, there is a group of 4 more digits. This new group of digits is combined alongside the earlier group with the use of a hyphen. ZIP+4 indicates a more specific mail delivery location.
ZIP Full Form: Zone Information Protocol
Full Form of ZIP is Zone Information Protocol. Our topic of discussion has an inseparable connection with AppleTalk. AppleTalk was essentially a proprietary suite comprising networking protocols, which was developed by, and as the name sounds, Apple, Inc for their operating systems. It covers a number of features facilitating Local Area Networks (abbreviated as LANs) to be connected without any previous set-up or any centralized server or router. Systems with AppleTalk will be assigned addresses automatically and be configured accordingly. It was a plug-n-play system. AppleTalk was released in the year 1985 and for a decade, it was the primary protocol for Apple devices.
Our topic—Zone Information Protocol (abbreviated as ZIP)—is closely associated with it, as it was the protocol that AppleTalk made use of to create an association with zone names. A Zone, for better elucidation, was a sub-division of the network, which was sensible to humans such as the Accounting Department. On the one hand, a network number was assigned topologically-contiguous portions of the network; on the other hand, a zone could cover different discontinuous sections of the network. ZIP, therefore, maintained mappings of the zone names associated with network numbers. It was primarily implemented by means of routers. However, that section of ZIP that was not implemented by means of a router was implemented by AppleTalk Protocol (abbreviated as ATP) for the purposes of sending requests about zone information to the router node.In order to appreciate more about this protocol, one has to extensively study the ATP and of course, the boss AppleTalk.
