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.
why they are essential in a bus oriented system? Ans) In a multiplexed bus system, many devices are linked to a common bus. If 2 or more devices attempt to use the bus at the si

Boolean algebra. Boolean algebra mathematical method based on human reasoning. In Boolean algebra only two states exist; true and false which are written as 1 (true) and 0 (fa
Explain about the term RTL Fix. RTL Fix: An RTL fix implies you change the Verilog/VHDL code and you resynthesize. This generally means a new Plance and Route. RTL fixes wou
Q. Explain the type of micro-operations? Let's first discuss type of micro-operations. Most common micro-operations performed in a digital computer can be categorized into 4 ca
An amplifier has an input resistance of 600 ohms and a resistive load of 75 ohms. When it has an rms input voltage of 100 mV, the rms output current is 20mA. Find the gain in dB.
Show that a positive logic NAND gate is equivalent to negative logic NOR gate. Ans: Positive logic denotes True or 1 with a high voltage and False or 0 with a low volt
