Nanotechnology is, in fact, a fairly extensive field of study and research at the moment. Physicists, chemists, biologists, material scientists, engineers, and computer scientists all contributed to its creation. In this paper, we examine how nanotechnology is evolving and growing, as well as how it may be utilised to construct a computer that is smaller, faster, and more trustworthy. In this work, we focus on the top-down and bottom-up manufacturing approaches to nanotechnology, which have a direct impact on current computer design and architecture. Researchers have been driven to enhance and produce a smaller, quicker, and more reliable computers due to the widespread usage of computers and their vast use in the contemporary world. Nanotechnology has the potential to achieve this goal. According to the definition of nanotechnology, it is the design, characterization, production, and application of structures, devices, and systems by controlled manipulation of size and shape at the nanometre scale atomic, molecular, and macromolecular scale, which results in structures, devices, and systems with at least one novel/superior characteristic or property. Passive nanostructures are the name given to this kind of structure.
