The communication interface, which manages data communication and the encoding/decoding of data. The master processor's integrated networking I/O, master processor-specific networking components
The network controller, a slave processor that manages the networking communication from the other logical units on the board The communication (COM) port, the component(s) on the embedded board in which a wired medium connects to or that receives the signal of a wireless transmission medium The transmission medium, as described in Section 4.2, wireless or wired medium(s) that connect the embedded system to a network

WHO MADE UP UNIVERSAL DATABASE SYSTEM SERIAL
Hardware such as that based on IEEE 802.3 Ethernet has the capability of supporting both serial and parallel communication and can be configured to manage data either way.įigure 4.12. Hardware that can manage data in parallel is a physical layer which has the ability to manage multiple bits simultaneously. Networking hardware that is classified as serial, such as EIA/RS-232, manages incoming and outgoing data one bit at a time. At the highest level, I/O networking hardware can be classified according to how the hardware manages the transmission and reception of data, specifically whether the physical layer manages data in serial, in parallel, or some hybrid combination of both. Networking hardware on a board falls under a type of I/O (input/output) hardware, and is responsible for transmitting data into and out of the device. In short, it is important for the reader to understand the networking relevant features of the hardware – and to use this understanding when analyzing the networking stack implementation that needs to support the particular underlying technology.

In other words, when a programmer learns about the networking hardware of a device, then it will be much simpler for the programmer to understand a particular networking protocol implementation, how to modify a particular protocol in support of underlying technologies, as well as determine which middleware networking protocol is the best ‘fit’ for the device. In other words, hardware features, quirks, and/or limitations will ultimately impact the type of networking library required and/or what modifications must be implemented in a particular networking stack to support this hardware. Thus, it is important for embedded developers to understand the differences in the hardware, in order to understand the implementation of a networking stack on which these various technologies reside. However, the underlying networking hardware available today is often quite different in terms of how it works.

Networking protocols residing at the higher layers of the OSI model view lower software layers that execute over different physical layer hardware as transparent.
