Computer Super Facts Questions pdf in Hindi

Hello Aspirants,

World’s First Computer: The world’s first electronic digital computer was called the ENIAC (Electronic Numerical Integrator and Computer). It was completed in 1945 and weighed about 30 tons.

Moore’s Law: Coined by Gordon Moore, the co-founder of Intel, Moore’s Law states that the number of transistors on a microchip doubles approximately every two years, leading to a rapid increase in computing power and a decrease in cost per transistor.

Computer Programming Languages: There are hundreds of programming languages, each designed for specific purposes. Some popular ones include Python, Java, C++, and JavaScript.

Supercomputers: Supercomputers are incredibly powerful machines used for complex simulations and calculations. As of my last knowledge update in September 2021, the world’s fastest supercomputer was Fugaku, located in Japan.

The Internet: The Internet was developed in the late 1960s and early 1970s. Its precursor, ARPANET, was created by the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA).

Computer Storage: The largest hard drive as of 2021 had a capacity of around 20 terabytes. However, storage technology continues to advance rapidly.

Computer Viruses: The first computer virus, known as the “Creeper” virus, was created in the early 1970s as an experiment. It didn’t cause harm but marked the beginning of cybersecurity concerns.

Artificial Intelligence: AI is a rapidly evolving field in computer science. Machine learning and deep learning have enabled computers to perform tasks such as image recognition and natural language processing with remarkable accuracy.

Quantum Computing: Quantum computers use quantum bits (qubits) instead of classical bits (0s and 1s). They have the potential to solve complex problems much faster than classical computers.

Computer Gaming: The video game industry is a massive part of the computer world. Games like Minecraft, Fortnite, and League of Legends have millions of players worldwide.

Computer Size: The size of computers has decreased dramatically over the years. The first computers filled entire rooms, while today’s smartphones are more powerful than early computers and fit in our pockets.

Computer Peripherals: Peripherals like keyboards, mice, and monitors are essential for interacting with computers. There are also specialized peripherals for tasks like graphic design and gaming.

Open Source Software: Many computer programs and operating systems are open source, meaning their source code is freely available for anyone to view, modify, and distribute.

Computer Ethics: The field of computer ethics deals with the moral and ethical issues related to the use of computers, including topics like privacy, cybersecurity, and artificial intelligence ethics.

Computer in Space: Computers play a critical role in space exploration and have been used in various spacecraft and space missions, including the Apollo moon missions and the Mars rovers.

These are just a few super facts about computers, and the field continues to evolve rapidly, with new developments and innovations happening all the time.
