Science and Computer Technology Quiz

RAM stands for Random Access Memory. It allows data to be accessed in any order (randomly) rather than sequentially, and each memory location can be accessed directly in roughly the same time regardless of physical location. 'Read Access', 'Read Available', and 'Read Allocated' are incorrect expansions of the acronym.

Charles Babbage is widely regarded as the father of the computer for designing the Analytical Engine in 1837, which contained the essential elements of modern computers including an arithmetic logic unit, control flow, and memory. His Difference Engine (1822) was also a pioneering mechanical calculator. Neither White Brothers, Einstein, nor Newton contributed to computer development.

Computers work on binary language at the hardware level. Binary uses only two digits - 0 and 1 - which correspond to electrical states (off/on). All data and instructions are ultimately represented in binary, which the computer's processor can directly execute. Computers do not natively work on English, Trinary (base-3), or Java (which is a high-level programming language).

Adobe is a software company (Adobe Systems), not an operating system. Adobe produces software like Photoshop, Acrobat, and Illustrator. Windows, Linux, and macOS (Mac) are all operating systems that manage computer hardware and software resources. Operating systems are system software, while Adobe products are application software.

CPU stands for Central Processing Unit, which is the primary component of a computer that executes instructions and processes data. It is often referred to as the 'brain' of the computer. 'Power' in options A and D is incorrect - the CPU does processing, not power generation.

ROM stands for Read Only Memory, which is a type of non-volatile memory that retains its data even when the power is turned off. As the name suggests, data can only be read from it and not written to (in standard ROM). 'Other', 'Over', and 'Output' are not part of the standard terminology.

Hard Drive, CD/DVD, and Pen Drive are all storage devices used to store and retrieve digital data. A Monitor is an output device that displays information, Mouse is an input device for pointing/clicking, and Mother Board is the main circuit board that connects all components - none of these are primarily for storage.

Robert G. Edwards won the 2010 Nobel Prize in Physiology or Medicine for his work on in vitro fertilization (IVF). Edwards developed the technique that led to the birth of the first 'test tube baby' in 1978, revolutionizing fertility treatment worldwide. Emil von Behring won the first Nobel Prize in 1901.

Andre Geim and Konstantin Novoselov won the 2010 Nobel Prize in Physics for their groundbreaking experiments with graphene, a two-dimensional carbon material. They discovered and isolated graphene at the University of Manchester, demonstrating its extraordinary properties. Both scientists worked together on this research.

Vitamins are organic compounds that the body requires in small amounts for proper metabolic function but do not provide energy. They act as cofactors for enzymes and support various physiological processes. In contrast, carbohydrates, fats, and proteins are macronutrients that yield energy when metabolized.
