General Science and Technology Acronyms Quiz

ABS stands for Anti-lock Braking System in vehicles. Option A 'Anti brake system' is the closest correct answer among the choices, though the complete term is 'Anti-lock Braking System'.

Proteins are polymers made of amino acid monomers linked by peptide bonds. Sucrose and glucose are carbohydrates, not protein building blocks.

Oryza sativa is the correct botanical name for Asian rice, the most widely cultivated rice species. The other options are names for different plants (Orthosiphon aristatus is a cat's whiskers plant, Achyranthes aspera is chaff-flower, Spiraea bella is a shrub).

ABS stands for Anti-lock Braking System. This is a duplicate of question 4188. Option A 'Anti Brake system' is closest to correct, though the full expansion is 'Anti-lock Braking System'.

ACL stands for Access Control List in networking and security, not Access Connection List. An ACL is a list of permissions attached to an object that specifies which users or system processes are granted access. Access Connection List is not a standard networking term, making the False option correct.

DDR (Double Data Rate) is a memory technology that transfers data on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to older Single Data Rate (SDR) memory. This synchronous timing mechanism is why it's called Double Data Rate, and it became the standard for computer RAM in the early 2000s.

GPS (Global Positioning System) is a satellite-based navigation system that provides location and time information anywhere on or near the Earth. Developed by the U.S. Department of Defense, it uses a network of satellites to triangulate positions and has become essential for navigation, timing, and mapping applications worldwide.

JPEG actually stands for 'Joint Photographic Experts Group' - the committee that created the standard. 'Excellent' is incorrect; the word 'Experts' is part of the name.

MIDI is indeed the standard protocol for electronic instruments and computers to communicate musical performance data. It transmits note information, velocity, and other control signals between musical devices.

PDF actually stands for Portable Document Format, not Page Document Format. It was developed by Adobe to present documents consistently across different platforms and software.

RAID stands for Redundant Array of Independent Disks (originally Inexpensive Disks). It combines multiple disk drives for data redundancy, performance improvement, or both, protecting against drive failure.

SATA stands for Serial ATA (Advanced Technology Attachment), not Tape Attachment. It's a computer bus interface for connecting storage devices like hard drives and SSDs to motherboards, replacing the older parallel ATA standard.

TFT does stand for Thin-Film Transistor, a technology used in LCD displays to improve image quality and response time. Each pixel is controlled by its own transistor, allowing for sharper, more responsive screens.

ODBC does stand for Open Database Connectivity, a standard API for accessing database management systems. It allows applications to communicate with different databases using a common interface, regardless of the underlying database system.

Sodium silicate (Na2SiO3) is commonly called 'water glass' because it forms a glassy solid and is soluble in water. It's used in cement, soap, and as a preservative for eggs. The other options are made-up names not used in chemistry.

Spirit of salt is hydrochloric acid (HCl), named so because it can be produced from common salt (NaCl) and was historically called 'spirit of salt' by alchemists. H2SO4 is sulfuric acid, H2NO3 is not a valid formula, and CaCl2 is calcium chloride.

Jeweler's rouge is ferric oxide (Fe2O3), a fine red powder used for polishing metals and gems due to its mild abrasive properties. Ferrous oxide (FeO) is black and used as a pigment, while ferrous sulfate and ferric sulfate are different compounds used as supplements and in water treatment, not for polishing.
