Embedded

Embedded means in electronics terms that a 'computer' is put inside of a product. The processor that is used it usually called a micro* controller unit (MCU) instead of a micro* processor unit (MPU). MCU's usually have a simple processor and a lot of on-board peripherals to save on part costs, PCB costs, design costs and debugging costs. The software is called embedded software.

Endianess

The big and little endian problem refers to the two possible ways to store the bytes of bigger words in memory, namely with the low order byte first (little endian) or with the high order byte first (big endian). The problem is that the little endian way has the advantage that the bytes are numbered from low to high ordered byte but the big endian way is more like how we humans write numbers (with the high order digits first). That makes big endian hex dumps and disassembly listings more easily readable.

EPROM

Erasable Programmable Read Only Memory.

These devices used to be UV erasable, so they had to have a quartz window on their top and had to be housed in a ceramic package. That would normally make them very expensive, but because they were produced in very large numbers their prices were quite moderate. Currently it's cheaper to use Flash EEPROM.

Exporting

The USA and a lot of it's partner contries have restrictions on what you can export to which contries.
