Charles Babbage is widely regarded as the 'father of the computer' for designing the Difference Engine (1822) and the Analytical Engine (1837), which introduced concepts like programmability and storage that are fundamental to modern computers. Note: 'Morden' in the question is a typo for 'Modern'.

CDAC (Centre for Development of Advanced Computing) is an Indian organization established in 1988, while ENIAC, EDVAC, and UNIVAC are all early American computers from the 1940s-1950s. The odd one out is CDAC because it's a modern Indian institution, not a vintage computer like the others.

Third generation computers (1965-1971) used Integrated Circuits (ICs), while VLSI (Very Large Scale Integration) technology was introduced in the fourth generation starting around 1971. VLSI allows thousands of transistors on a single chip, far more advanced than the ICs used in third generation systems.

FLOPS (Floating Point Operations Per Second) is indeed the standard unit for measuring supercomputer performance. It counts how many floating-point calculations a computer can perform in one second, making it ideal for comparing computational speed of systems designed for complex mathematical and scientific calculations.

To convert binary 1101 to decimal, calculate: 1×2³ + 1×2² + 0×2¹ + 1×2⁰ = 8 + 4 + 0 + 1 = 13. The positions represent powers of 2 from left to right (8, 4, 2, 1), so summing the values where there's a 1 gives 13.

BCD does indeed stand for Binary Coded Decimal. It's a encoding scheme where each decimal digit (0-9) is represented by a fixed 4-bit binary code. For example, decimal 7 is 0111 in BCD. This is commonly used in digital systems where decimal arithmetic needs to be performed.

Jupiter's atmosphere is primarily composed of hydrogen (about 90%) and helium (about 10%), similar to the composition of the Sun and the primordial solar nebula. The remaining trace gases include methane, ammonia, water vapor, and other compounds. This composition makes Jupiter a gas giant.

The Foucault pendulum, demonstrated by Léon Foucault in 1851, provides direct visual evidence of Earth's rotation. As the pendulum swings, the plane of oscillation appears to rotate due to Earth's rotation beneath it. This experiment elegantly proves Earth's rotation without relying on astronomical observations.

The Big Bang theory describes the origin of the universe as an expansion from a singularity. Edwin Hubble's observations in the 1920s provided the first evidence that galaxies are moving away from each other, confirming the universe is expanding. This expansion continues today - the universe is not contracting, remaining stable, or pulsating.

A pulsar is a highly magnetized, rotating neutron star that emits beams of electromagnetic radiation from its magnetic poles. As the star rotates, these beams sweep across space like a lighthouse - we detect them as regular pulses. Quasars are active galactic nuclei, not neutron stars.

The gravitational pull of a black hole is so strong that nothing can escape once past the event horizon - not even light or electromagnetic radiation. The escape velocity exceeds the speed of light. Hawking radiation theoretically allows very slow energy loss, but this is negligible - practically, nothing escapes.

Titan is the only moon in our solar system with a substantial atmosphere - mostly nitrogen with methane and ethane. Its atmosphere is denser than Earth's. Tethys and Dione are airless icy moons of Saturn. Huygens was the probe that landed on Titan.

Hubble's Law states that galaxies are moving away from us at speeds proportional to their distance - more distant galaxies recede faster. This was key evidence for the expanding universe and Big Bang theory. Kepler's laws describe planetary motion, Huygens studied wave theory, and Friedmann developed cosmological models.

A quasar is an extremely luminous active galactic nucleus powered by a supermassive black hole. They emit enormous energy across the electromagnetic spectrum, especially in radio frequencies. Pulsars and neutron stars are different objects - rotating stellar remnants, not galactic nuclei.

Olympus Mons on Mars is the tallest volcano and mountain in the solar system at about 22 km (13.6 miles) high - nearly 3 times Mount Everest's height. It's a massive shield volcano. Stromboli is in Italy, Fujiyama is in Japan, and Orcus is not a known major volcano.

Black holes have such intense gravitational field due to their extremely high density (mass concentrated in a tiny volume) that nothing, not even radiation or light, can escape from beyond the event horizon. The escape velocity exceeds the speed of light. The size of a black hole (event horizon) depends on its mass, but the key property is the density. Small or large size alone doesn't create a black hole - it's the mass-to-volume ratio (density) that matters.

Dr. Christiaan Barnard performed the world's first human-to-human heart transplant on December 3, 1967 at Groote Schuur Hospital in Cape Town, South Africa. The patient, Louis Washkansky, lived for 18 days after the pioneering surgery.
