If your embedded system is on a network, the key question is: what subset of TCP/IP will you include in your product?

The first generation of network processors is finally here. But what are they good for and how do they work?

Major semiconductor manufacturers are starting to sell a new type of integrated circuit, the network processor. Network processors are programmable chips like general purpose microprocessors, but are optimized for the packet processing required in network devices.

Which is the most convenient end on your system? The choices are big endian and little endian.

Some human languages are read and written from left to right; others from right to left. A similar issue arises in the field of computers, involving the representation of numbers.

The address resolution protocol provides a necessary bridge between physical and logical addresses on a TCP/IP network.

Every system on a TCP/IP network has two addresses, one physical and one logical. The address resolution protocol (ARP) provides a necessary bridge between these two addresses.

As engineers design more and more products with embedded computer systems that require connections of one sort or another, we've got to pay attention to the ease with which these connections can be made. Short-range wireless protocols offer an attractive alternative to wired connections.
