The document discusses nano computing and was presented by Ankit Kumar Dubey. It defines nano computing as computing using extremely small nano-scale devices. It discusses the types of nano computing including nano electronic, nano mechanical, nano chemical and biochemical, and nano quantum computers. It explains that nano computers work by storing data in atomic quantum states or spin using methods like spin electron transistors and quantum dots based on quantum mechanics principles. The document outlines some advantages like high performance and low power computing but also challenges like higher costs. It concludes nano computing will be an enabling technology that changes almost every human-made object in the next century.
