Whenever there is a comparison of GDPs amongst the countries, Purchasing Power Parity (PPP) concept is very vital to understand. Gross domestic Product (GDP) represents an accounting of the total value of all final goods and services produced in a geographic region over a specific period of time, usually one year.
From Wikipedia, the free encyclopedia. A globally unique identifier (GUID, /ËÉ¡aÉªd/ or /ËÉ¡uËÉªd/) is a unique reference number used as an identifier in computer software. The term GUID typically refers to various implementations of the universally unique identifier (UUID) standard.
The unique identifier (UID) is an identifier that refers to only one instance âonly one particular object in the universe. A part number is an identifier, but it is not a unique identifierâfor that, a serial number is needed, to identify each instance of the part design.n most languages, some character sequences have the lexical form of an identifier but are known as keywords â for example, if is frequently a keyword for an if clause, but lexically is of the same form as ig or foo namely a sequence of letters.
