Q. Explain working of Supercomputer?
Supercomputers, capable of executing in excess of one billion floating-point operations per second (FLOPS), are very powerful, extremely high-performance computers for applications that are beyond the reach of the mainframes, and cost more than ten million dollars. These are used for weather prediction, image processing, and nuclear-energy studies that require high-precision processing of ordered data achieved by a speed advantage due to parallel processors. Cyber 205, Cray X-MP, and Cray 2 are some examples of supercomputers. In the 1980s, supercomputing centers were developed at six American universities for high performance computing. By 1990 it was possible to build chipswith amillion components; semiconductormemories became standard in all computers; widespread use of computer networks and workstations had occurred. Explosive growth of wide area networking took place with transmission rates of 45 million bits per second.
Q. Find simplified function F and implement that function using only NAND gates. 1. F(A,B,C) = (A+B) (A'+B+C') (A'+B'+C') 2. F (A,B,C) = A'B'C'+B'CD'+A'BCD'+AB'C' 3. F(X,Y
