Chemistry Knowledge Quiz

Chemistry is the scientific study of the properties and behavior of matter.

Chemistry studies the chemical elements that make up matter and compounds made of atoms, molecules, and ions: their composition, structure, properties, behavior, and the changes they undergo during reactions with other substances.

Chemistry is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.

<p>Chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).</p> Signup and view all the answers

<p>A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory. It functions as secondary storage in the hierarchy of computer storage by storing data persistently and providing faster access to data compared to traditional hard disk drives (HDDs).</p> Signup and view all the answers

<p>SSDs are typically more resistant to physical shock, run silently, and have higher input/output rates and lower latency compared to hard disk drives (HDDs) and similar electromechanical media.</p> Signup and view all the answers

<p>SSD storage devices vary in their properties according to the number of bits stored in each cell. Single-bit cells (SLC) are generally the most reliable, durable, fast, and expensive type, compared with 2- and 3-bit cells (MLC and TLC), and finally, quad-bit cells (QLC) are used for consumer devices that do not require such extreme properties and are the cheapest per gigabyte (GB) of the four.</p> Signup and view all the answers

<p>As of 2019, cells in SSDs can contain between 1 and 4 bits of data. This impacts the storage devices as it affects their reliability, durability, speed, and cost, with single-bit cells being generally the most reliable, durable, fast, and expensive type, while quad-bit cells are the cheapest per gigabyte (GB) of the four.</p> Signup and view all the answers
