Embedded Computers-Another offbeater
Since there are not much things in the celebrity world I would like to come again with another offbeater.Here you go-An embedded computer is a special-purpose computer system designed to perform one or a few dedicated functions. Since the embedded system is dedicated to perform specific tasks, they can be optimized thereby reducing the size and cost of the product, or increasing the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale. Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks. Some of their salient features are discussed in the following paragraph.
Embedded systems are not always separate devices. Most often they are physically built-in to the devices they control. The software written for embedded systems is often called firmware, and is stored in read-only memory or Flash memory chips rather than a disk drive. It often runs with limited computer hardware resources: small or no keyboard, screen, and little memory. These embedded computers find their use in industrial computing. Their extreme memory and fastness leads to their use in industrial computing.
Now let’s discuss about Computer-On-Module. A computer-on-module (COM) is a type of single-board computer (SBC). The COM module is a complete computer built on a single circuit board. The design is centered on a single microprocessor with RAM, input/output and all other features needed to be a functional computer on the one board. However, unlike a single-board computer, the COM module will usually lack the standard connectors for any input/output peripherals to be attached directly to the board. Instead, the wiring for these peripherals is brought out to pin-headers on the board. The module will usually need to be mounted on a baseboard which has the standard peripheral connectors.
The future of embedded system is really good and a research in embedded systems would surely prove useful.
