Computer Science and General Science Quiz

ICANN (Internet Corporation for Assigned Names and Numbers) is the non-profit organization that coordinates internet identifiers globally. This includes managing domain names, IP addresses, and protocol parameters. ICANN does not control internet content access - it only manages the technical infrastructure that keeps the internet organized.

Tim Berners-Lee invented the World Wide Web in 1989 at CERN, the European Organization for Nuclear Research, located in Geneva, Switzerland. He developed the web to help scientists share information more easily. The first website went live in 1991.

Static electricity refers to the electric charge that builds up on the surface of objects due to friction or contact. This occurs when there is an imbalance of electric charges within or on the surface of a material. Friction causes the charge buildup but static electricity is the phenomenon itself.

Bees have 5 eyes in total - 2 large compound eyes on the sides of their head and 3 simple eyes (ocelli) arranged in a triangular pattern on top of their head. The simple eyes detect light intensity and help with navigation while the compound eyes form images. This anatomical fact is standard in entomology.

Earth's equatorial radius is 6378.1 km, which is the distance from Earth's center to the equator. Earth is not a perfect sphere but an oblate spheroid, so the equatorial radius is larger than the polar radius of approximately 6357 km.

Yuri Gagarin became the first human in space on April 12, 1961, aboard the Soviet spacecraft Vostok 1. This historic mission occurred during the Space Race between the United States and Soviet Union, marking a major milestone in human space exploration.

Isaac Newton was born in 1642, specifically on December 25th (Old Style calendar). This date is commonly cited as his birth year in historical records. The other options (1672, 1665, 1645) are incorrect and do not match documented birth records.

ASCII (American Standard Code for Information Interchange) is the standard character encoding scheme for electronic communication between terminals and computers. It uses a 7-bit code to represent 128 characters, including letters, numbers, and control characters. BCD is for binary-coded decimal representation, BCDIC is IBM's punched card code, and Hollerith is an older punched card system.

CD audio players use laser beam technology to read the digital information stored on the compact disc. The laser reflects off the microscopic pits and lands on the disc surface, and the reflection pattern is converted to audio signals. This non-contact optical method is what distinguishes CDs from vinyl records that use needles.

ASCII was designed as an independent character encoding system, separate from earlier punched card codes like Hollerith. Unlike zone-based punched card codes, ASCII uses a straightforward 7-bit binary pattern for each character. ASCII can represent 128 characters, not 96, and doesn't use zone codes like those mentioned in option B.

Charles Babbage designed the Difference Engine in the 1820s-1840s as a mechanical calculator for computing polynomial functions. ENIAC was built in the 1940s, long after Babbage's time. The first electronic computer is generally considered to be ENIAC or Colossus, and punched cards were developed by Herman Hollerith.

MIPS (Million Instructions Per Second) is the standard metric for comparing processor speeds. It indicates how many millions of instructions a CPU can execute in one second. FFTS refers to Fast Fourier Transform, MPG could relate to fuel efficiency or file compression, and CPS is cycles per second (another valid speed measure, but MIPS is more commonly used for processing speed comparison).

Batch processing involves accumulating transactions and processing them together at a scheduled time, which is ideal for daily customer account corrections. These corrections don't need immediate processing and can be efficiently handled in batches during off-peak hours. Real-time processing would be for immediate updates, time-sharing is for interactive use, and off-line processing uses disconnected peripheral devices.

Mini-computers historically were designed for specific tasks in organizations, unlike general-purpose mainframes. While option A is false (plotters are available for microcomputers), option B is false (microcomputers are programmed like conventional computers), and option D is false (ROM contents are not easily changed - that's why it's called Read Only Memory), option C captures a historical characteristic of mini-computers.

A register is a small, high-speed storage location directly within the CPU used to hold data, instructions, or memory addresses during processing. Registers can be general-purpose (used for various operations) or dedicated (special functions like program counter or stack pointer). Options A and C describe physical paper media, and registers are part of primary memory, not auxiliary memory.

A byte consists of eight binary digits (bits), which can represent 256 different values (2^8). This is the fundamental unit of digital storage in computers. Each bit is a binary digit (0 or 1), and eight bits together form a byte, which is used to represent a single character or small integer value.
