(RISC)is a processor design strategy that uses a much simplified instructions set than traditional Complex Instruction Set Computers (CISC) .The philosophy behind using RISC was that CISC architecture was not as fast and flexible to growth as RISC. The RISC architecture was shown to be more flexible and faster on several occasions when performing the same operations. The RISC processors of 1980s were very simple from the ones available currently available in the market. These processors only consisted

Animals Should Not Be Tested On “Mice are mice‚ and people are people. If we look to the mouse to model every aspect of the disease of man‚ and model cures‚ we are just wasting our time.” - Dr. Clif Barry. Animal rights have been fought for by many people‚ but it just never works. Animals can feel pain just as much as humans can‚ but the worst part is animals can not help themselves. Animal testing should be illegal for many reasons‚ here are just a few. Almost ninety percent of tests/drugs

module does not interrupt CPU • CPU may wait or come back later Example • To increase efficiency for programmed I/O‚ the software could be written so that the processor periodically checks the status of the device. If the device is not ready‚ the processor can jump to other tasks. After some timed interval‚ the processor comes back to check status again. • Consider the above scheme for outputting data one character at a time to a printer that operates at 10 characters per second.

-John von Neumann John von Neumann‚ born December 28‚ 1903 was a Hungarian mathematician who made important contributions to computer science‚ von Neumann is best known for his EDVAC (Electronic Discrete Variable Automatic Computer) which opposed the not yet released ENIAC (Electronic Numerical Integrator and Computer). Neumann’s EDVAC design was intended to resolve many of the problems created by the ENIAC’s design. The ENIAC was designed to operate in decimal‚ whereas the EDVAC was designed

It is considered the brain of the computer because all of the instructions it performs are mathematical calculations and logical comparisons. • A 64-bit processor is a processor with a default word size of 64 bits and a 64-bit external data bus‚ which allows you to access much more RAM than a 32-bit processor. • The amount of RAM
