The difference between one pass and two pass assemblers are:-
A one pass assembler passes over the source file exactly once, in the same pass collecting the labels, resolving future references and doing the actual assembly. The difficult part is to resolve future label references and assemble code in one pass.
A two pass assembler does two passes over the source file ( the second pass can be over a file generated in the first pass ). In the first pass all it does is looks for label definitions and introduces them in the symbol table. In the s ....etc

A molecular assembler as defined by K. Eric Drexler is a proposed device able to guide chemical reactions by positioning reactive molecules with atomic precision. Some biological molecules such as ribosomes fit this definition, since while working within a cell's environment, they receive instructions from messenger RNA and then assemble specific sequences of amino acids to construct protein molecules. However, the term molecular assembler usually refers to theoretical man-made or synthetic devices. Development of ribosome-like molecular as ....etc

Nano network are constructed at a nanometer scale. This discusses use of individual nanotubes within random carbon nanotube networks to carry information. The networking protocol stack is inverted in this approach because the CNT network and
routing of information is an integral part of the physical layer.
A nano communication network or CNT network is rich in nanotubes which are densely packed. CNT network itself is the communication
media and individual nanotubes are the links. Individual tubes and tube junctions
forms nodes but do not ha ....etc

Nanoelectronics and nanomirror memory
Nanoelectronics refer to the use of nanotechnology on electronic components, especially transistors. .nanoelectronics often refer to transistor devices that are so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. hybrid molecular/semiconductor electronics, one dimensional nanotubes/nanowires, or advanced molecular electronics are the present candidates that fall in the nanoelectronic component category. Nanoelectronics holds the promise of making ....etc

ABSTRACT

Materials Science research is now entered a new phase where the structure and properties of materials are investigated, characterized and controlled at the nanoscale. Though as sophisticated as their larger counterparts, these devices are still burdened because they rely on an outside power. The size of the entire device is determined by the size of the power source. Batteries and other traditional sources are too large, and tend to negate the size advantages of nano devices. Also, batteries being used at present require toxic ch ....etc
