Data Analysis Expressions (DAX) is the native formula and query language for Microsoft PowerPivot, Power BI Desktop and SQL Server Analysis Services (SSAS) Tabular models. DAX includes some of the functions that are used in Excel formulas with additional functions that are designed to work with relational data and perform dynamic aggregation.
Power Query is built on what was then [when?] a new query language called M.It is a mashup language (hence the letter M) designed to create queries that mix together data.

Past hardware had a CISC instruction set with 48-bit addressing, while current hardware is 64-bit PowerPC/Power ISA. In the PowerPC/Power ISA implementation, the first four bytes contain information used to identify the type of the object being referenced, and the final eight bytes are used as a virtual memory address.
