Question : 27 [SBI Clerk, 2009]
Which of the following refers to the fastest, biggest and most expensive computers ?
a) Personal Computers
b) Supercomputers
c) Laptops
d) Notebooks
e) None of these
Answer »Answer: (b)
A supercomputer is a computer that performs at a high level than a general-purpose computer.
Instead of million instructions per second, the performance of a supercomputer is often measured in floating-point operations per second (FLOPS) (MIPS).
All the world's fastest 500 supercomputers have been running Linux-based operating systems since November 2017.
In the United States, the European Union, Taiwan, Japan, and China, more research is being done to develop faster, more powerful, and technologically better exascale supercomputers.
Quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modelling (computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals), and physics are just a few of the computationally intensive tasks that supercomputers are used for (such as simulations of the early moments of the universe, aeroplane and spacecraft aerodynamics, the detonation of nuclear weapons, and nuclear fusion).
Question : 29
Which of the following refers to the fastest, biggest and most, expensive computers?
a) Notebooks
b) Personal Computers
c) Laptops
d) Supercomputers
e) PDAs
Answer »Answer: (d)
The supercomputer, is any of a class of extremely powerful computers. The term is commonly applied to the fastest high-performance systems available at any given time. Such computers have been used primarily for scientific and engineering work requiring exceedingly high-speed computations. Common applications for supercomputers include testing mathematical models for complex physical phenomena or designs, such as climate and weather, the evolution of the cosmos, nuclear weapons and reactors, new chemical compounds (especially for pharmaceutical purposes), and cryptology. As the cost of supercomputing declined in the 1990s, more businesses began to use supercomputers for market research and other business-related models.
Question : 30
