SQL is an acronym for what?

• Sortable Quota List
• Standard Query Language
• Simple Query Logic
• Structured Query Language

EXPLANATION

SQL is a domain-specific language used in programming and designed for managing data held in a relational database management system, or for stream processing in a relational data stream management system. It is particularly useful in handling structured data where there are relations between different entities/variables of the data 

SQL (/ˌɛsˌkjuːˈɛl/ ( listen) S-Q-L, /ˈsiːkwəl/ "sequel"; Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).

What does the acronym DDR stand for?

• Direct Data Replication
• Double Data Rate
• Double Diet Rampage
• Direct Duplication Requirement

EXPLANATION

In computing, a computer bus operating with double data rate transfers data on both the rising and falling edges of the clock signal. This is also known as double pumped, dual-pumped, and double transition. The term toggle mode is used in the context of NAND flash memory.

In terms of digital information storage which of the following is a multiple of a bit?

In terms of digital information storage which of the following is a multiple of a bit?

• overbite
• zebibit
• cubit
• weebit

EXPLANATION

Zetta- and Zebi-

• Zettabit. A unit of information or storage abbreviated Zbit or Zb. One zettabit most typically equals 10²¹ or 1,000,000,000,000,000,000,000 bits (one sextillion or one trilliard in long scale measure*). Note: Zettabit is not yet used; thought it’s only a matter of time before it is.
• Zebibit. A unit of information or storage abbreviated Zibit or Zib. This is the absolute binary measure equaling 1,180,591,620,717,411,303,424 (2⁷⁰) bits. Use it when precision is needed. Note: Zebibit is not yet used; thought it’s only a matter of time before it is.
• Zettabyte. A unit of information or storage abbreviated ZB. Again, there are/will be confusing interpretations for this term for different contexts (also see the more general discussion above).
• 1,000,000,000,000,000,000,000 bytes (10²¹) when used in a networking context, clocks, or performance measures.
• 1,180,591,620,717,411,303,424 (2⁷⁰) bytes. This definition is used for memory, file and formatted disk size, and other contexts where binary notation fits better.
• Zebibyte. A unit of information or storage abbreviated ZiB. This is the specific measure of the binary representation of 1,180,591,620,717,411,303,424 (2⁷⁰) bytes. When precision is demanded, this is the term to use.
