Science and Technology General Knowledge Quiz

A capacitor is an electronic component designed to store electric charge. It consists of two conductive plates separated by an insulating material (dielectric). When voltage is applied, charge accumulates on the plates, creating an electric field that stores energy. Capacitors are commonly used for filtering, energy storage, and timing circuits.

Dust on circuit boards acts as an insulating layer that traps heat, preventing components from dissipating thermal energy effectively. This can lead to overheating, reduced performance, and potential component failure. Dust can also conduct electricity if it contains conductive particles or absorbs moisture, but overheating is the primary consequence.

Paseo is a Toyota car model, not a computer. Aptiva was IBM's consumer line of personal computers in the 1990s. Macintosh is Apple's iconic computer line. Acorn Computers was a British computer manufacturer known for the BBC Micro and ARM architecture development.

In technology, a hot spot refers to a location that provides public wireless internet access, such as coffee shops, airports, or libraries. It is not related to CPU overheating (thermal throttling), adult websites, or programming bugs.

DOCSIS stands for Data Over Cable Service Interface Specification, which is the international standard used for delivering internet service over coaxial cable networks. It enables high-speed data transmission on cable television infrastructure.

The Sun is the nearest star to Earth, at an average distance of about 93 million miles (150 million km). The Moon is Earth's satellite, not a star. Jupiter and Mercury are planets, not stars.

Gold is heavier (more dense) than silver, copper, or iron. Gold has a density of about 19.3 g/cm³, compared to silver (10.5 g/cm³), copper (8.96 g/cm³), and iron (7.87 g/cm³). This is why gold feels significantly heavier for the same volume.

Bamboo is a grass family (Poaceae) member and the tallest, with some species reaching 30+ meters and stems 20-30cm thick. Blue Oat Grass and Buffalo Grass are low-growing ornamental lawn grasses, while Tall Fescue reaches only 2-3 feet.

Citric acid (C6H8O7) is a naturally occurring organic acid found abundantly in citrus fruits like lemons, oranges, limes, and grapefruit, giving them their characteristic sour taste. Sulphuric acid is a strong mineral acid, acetic acid is found in vinegar, and amino acids are protein building blocks.

Earth is the only planet not named after a Roman or Greek god. Jupiter (king of gods), Mars (war god), and Venus (love goddess) were all Roman deities. Earth's name comes from Old English/Germanic words meaning ground.

The thigh bone (femur) is stronger than concrete pound-for-pound due to its dense cortical bone structure. It can withstand considerable pressure. Teeth are not bones (enamel/dentin), and while the skull is tough, it's not comparable to femur strength.
