In computing, a nibble is defined as 4 bits, which is half a byte (8 bits). This is a standard term in digital systems and computer architecture.

Apple Inc. was founded by Steve Jobs and Steve Wozniak in 1976. While Steve Jobs was the public face, Steve Wozniak was the technical co-founder who designed the Apple I and Apple II computers.

C++ was originally named 'C with Classes' by its creator Bjarne Stroustrup when he first developed the language at Bell Labs starting in 1979. The name was changed to C++ in 1983, with the '++' being from the C increment operator. 'C' and 'C+' were different languages/proposals, not earlier names of C++.

The CPU consists of three primary components: the Control Unit (CU) that manages instruction flow, the Arithmetic Logic Unit (ALU) that performs mathematical and logical operations, and registers that store temporary data. RAM and ROM are separate memory units that work alongside the CPU but are not part of its internal architecture.

Pipelining is a fundamental CPU architecture technique where multiple instruction phases are overlapped to improve performance. While one instruction is being executed, another can be decoded and a third fetched - similar to an assembly line. Drilling, refining, and blasting are industrial processes unrelated to computing.

1 gram weight equals approximately 981 dynes because 1 dyne = 10^-5 newtons and 1 gram weight = g × 10^-3 newtons where g ≈ 9.81 m/s². This gives us 981 dynes. The other values (903, 376, 257) don't match this conversion.

The MKS (meter-kilogram-second) system uses the Joule as the unit of energy. Joule = kg × m²/s² in MKS units. Volt is for electric potential, Erg is the CGS unit of energy, and Ohm is for electrical resistance.

C.V. Raman (Chandrasekhara Venkata Raman) won the Nobel Prize in Physics in 1930 for his discovery of the Raman Effect - the scattering of light by molecules. J.C. Bose was a renowned scientist but did not win a Nobel Prize, Amartya Sen won the Nobel in Economics (1998), and G.D. Naidu was an inventor but not a Nobel laureate.

The golden ratio (phi, approximately 1.618) is defined by the relationship (a+b)/a = a/b where a is the larger segment and a+b is the total length. This means the ratio of the sum to the larger part equals the ratio of the larger to the smaller part. Option D correctly expresses this mathematical relationship.
