WWW (World Wide Web) is a system of interconnected documents and resources linked by hyperlinks and URLs, accessed through web browsers. Invented by Tim Berners-Lee in 1989 at CERN, it forms the information space that we navigate when using the internet.

Petrol engines typically convert only about 25-30% of fuel energy into mechanical work, with the rest lost as heat through exhaust and cooling systems. This relatively low efficiency compared to diesel engines (40-45%) is due to petrol's lower compression ratio and combustion characteristics.

The Cardamom Hills, part of the southern Western Ghats extending through Kerala's Idukki and Kottayam districts, represent among the southernmost hill ranges in mainland India. While the Nilgiri Hills lie to their north in the Western Ghats, the Cardamom range extends further south toward Kerala's border regions.

Network speed is measured in data transfer rate per second, not in processor speed (MHz), storage capacity (Megabytes), or memory (RAM). Kbps (kilobits per second) is the standard unit for measuring internet connection speed, indicating how many thousand bits of data can be transmitted each second. This reflects bandwidth capacity, not processing power or storage.

Marsh gas is the common name for methane (CH4), a simple hydrocarbon gas formed by anaerobic decomposition of organic matter in wetlands and marshes. Methane is the primary component of natural gas and is the simplest alkane with one carbon atom bonded to four hydrogen atoms. The other options either represent incorrect chemical formulas or combinations that don't correspond to marsh gas.

The Shekel (also spelled Sheqel) is the official currency of Israel. While the spelling 'Shequel' in the question appears to be a variant, it clearly refers to the Israeli currency. Nairobi is a city, not a country, and neither Iran nor Iraq use the Shekel as their currency (Iran uses Rial, Iraq uses Dinar).

AOL stands for America Online, which was one of the earliest and most prominent internet service providers and online services companies. Founded in 1983, it became synonymous with internet access in the 1990s. The other options are fabricated expansions that don't correspond to what AOL actually represents.

ISDN (Integrated Services Digital Network), DSL (Digital Subscriber Line), and Modem are all technologies or devices used to connect to the internet. CPU (Central Processing Unit) is the computer's processor component, not a method of accessing the web. The CPU processes data but doesn't provide network connectivity itself.

Yahoo is a web portal - a website that serves as a starting point or gateway to other content on the internet. Portals typically offer services like email, news, search, entertainment, and various online resources all in one place. Yahoo is not a supercomputer, it doesn't allocate web addresses (that's ICANN's role), and while consumers use it, 'portal' is the more specific technical classification.

A cache is temporary storage that holds frequently accessed data to speed up future requests. Web browsers use cache to store recently visited pages and graphics so they don't have to be re-downloaded, making browsing faster. 'Niche' and 'Cellar' are unrelated terms, and 'Webspace' typically refers to hosting storage, not browser cache.
