| UDP | A connectionless protocol that, similar to TCP but without guaranteed packet delivery, runs over IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It's used primarily for broadcasting messages over a network where the loss of an individual packet can be overlooked. |
| Unit of Measure | The unit of measure describes how the quantity of an item is tracked in your inventory system. The most common unit of measure is "eaches" (EA), which simply means that each individual item is considered one unit. An item that uses "cases" (CA or CS) as the unit of measure would be tracked by the number of cases rather than by the actual piece quantity. Other examples of units of measure would include pallets (PL), pounds (LB), ounces (OZ), linear feet (LF), square feet (SF), cubic feet (CF), gallons , thousands, hundreds, pairs, dozens.

| Unit Test | Method constructed with special test syntax to describe the expected outcomes of given method inputs. A unit test will call a method or function with inputs that have known, expected return values. Any changes to the method which cause its return values to conflict with the known, expected return values will cause an exception. This exception signals that this method must be corrected; no further testing is necessary if the corrections then make the method return the known, expected return values. |
| Unit Testing | In computer programming, a unit test is a procedure used to validate that a particular module of source code is working properly. The procedure is to write test cases for each function and method so that whenever a change is made to unit-tested code, its unit test will fail. The malfunctioning code can then be quickly identified and fixed. Ideally, each test case is separate from the others. This type of testing is mostly done by the developers and not by end-users. See Test Driven Development (TDD). |
| URL | Universal Resource Locator - the global address of documents and other resources on the World Wide Web (WWW). The first part of the address indicates what protocol to use, the second part specifies the IP address or the domain name where the resource is located, and the third part specifies the directory structure and/or file name. |
| User Experience | A term used to describe the overall experience and satisfaction a user has when using a product or system.
