Sericulture is the cultivation of silkworms for the production of silk. The most widely practiced form of sericulture, known as mulberry sericulture, relies entirely on the Mulberry plant (Morus spp.). The silkworm species Bombyx mori, responsible for producing the majority of commercial silk, feeds exclusively on mulberry leaves. The quality and abundance of mulberry leaves are crucial factors directly influencing the health of the silkworms and, consequently, the yield and quality of the silk cocoons. While other plants like Castor, Oak, and Som are food sources for different, less common types of silkworms (Eri, Tasar, and Muga silk, respectively), Mulberry is the key plant for the predominant silk industry.

CPU stands for Central Processing Unit. It is often referred to as the "brain" of the computer because it is the primary component that performs most of the processing inside a computer. Its main function is to execute instructions, perform arithmetic and logical operations, and manage the overall flow of data and instructions within the computer system.

Dr. A. P. J. Abdul Kalam is universally acknowledged as the "Father of Indian Missile Technology." His instrumental leadership and contributions to the Integrated Guided Missile Development Programme (IGMDP) were crucial in propelling India's capabilities in ballistic missile and launch vehicle technology. Under his guidance, India successfully developed indigenous missiles such as Prithvi, Agni, Akash, Trishul, and Nag. Beyond his scientific achievements, he also served as the 11th President of India, solidifying his legacy as a visionary leader and scientist.

Astronomy is a natural science that involves the scientific study of celestial objects (such as stars, planets, comets, galaxies, and nebulae), the universe as a whole, and the phenomena that originate beyond Earth's atmosphere. It uses principles of mathematics, physics, and chemistry to understand their origin, evolution, physical and chemical properties, and behavior. While cosmology is a branch of astronomy that focuses on the universe's origin, evolution, and large-scale structure, astronomy encompasses the broader study of all extraterrestrial objects and phenomena.

The ancient Indian text "Rasaratnakara" (meaning "Ocean of Mercury" or "Jewel Mine of Mercury"), which delves into the intricacies of alchemy, metallurgy, and chemistry, is widely attributed to the Indian metallurgist and chemist Nagarjuna. This work is significant for detailing processes like the extraction of various metals including gold, silver, tin, and copper. While there can be some historical ambiguity due to multiple individuals bearing the name Nagarjuna and other texts with similar titles (like a 13th-century work by Nityanatha Siddha), the most prominent "Rasaratnakara" in the context of ancient Indian chemistry is associated with Nagarjuna, often placed around the 8th century AD.

A bit (binary digit) is the smallest and most fundamental unit of data in computing. It represents a single binary value, either a 0 or a 1. All other units of digital data, such as bytes, kilobytes, megabytes, etc., are made up of combinations of bits. A byte, for example, is composed of 8 bits.
