      Embedded Systems

      Embedded systems refer to devices, instruments or large engineering structures/systems that are built to handle one or a few pre-established tasks. The computer controlling the whole thing is built into or 'embedded' within the device. Cellphones and personal digital assistants (PDAs) are examples of devices with embedded systems. They both perform a specific number of

    • Lightning Arrester

      Lightning Arrester

      A lightning/surge arrester is a device that protects structures from electrical damage by intercepting lightning surges and diverting them to the ground. Lightning arresters are connected directly to the ground via low resistance cables, although they are generally mounted on high buildings or other structures in order to attract electricity. They can be used on

    • Flash Memory

      Flash Memory

      Flash memory is a nonvolatile memory type that is constantly-powered. It has the capability to be reprogrammed or erased in various units of memory referred to as blocks. The technology is based on EEPROM (erasable programmable read-only memory) that is written and erased at the byte level which operates at a much slower rate than

    • SAN Zoning

      SAN Zoning

      SAN zoning is a method of arranging Fibre Channel devices into logical groups over the physical configuration of the fabric. SAN zoning may be utilized to implement compartmentalization of data for security purposes. Each device in a SAN may be placed into multiple zones. Hard and Soft Zoning Hard zoning is zoning which is implemented

      How to Measure Signal Quality

      Most people usually look to Signal to Noise Ratio to measure the signal quality of either audio or video communications. Signal to noise ratio is usually written either S/N or SNR. Most of the time the signal to noise ratio is measured in decibels. A decibel is a measure of power or loudness. Not to

      DNA Computer

      DNA computers will be the next-generation computers made of genes' building blocks. Because of their speed, miniaturization and data storage potential DNA computers are being considered as a replacement for silicon-based computers. Current DNA computer research has already proven that DNA computers are capable of solving complex mathematical equations and storing enormous amounts of data.

      Cache

      Computer caches are memory circuits that serve to speed up a much larger memory drive. In a typical computer it takes the microprocessor 60 nanoseconds to access the RAM. To cut the time it takes for the microprocessor to access data from the RAM, a special memory bank or memory circuit is installed into the
