Downloading an application mean to hardware means what ?

Embedded C interview question

What does down loading an application mean?

Answer

Refers to the transfer of executable code from a host to a target, typically using an RS-232 serial line. The target must have resident software (e.g., EPROM) that can read the incoming data, translate it if necessary (the file format may be ASCII hex for example) and load and run the code. If the target board has no resident software, then an ICE is required. The ICE connects to the host via RS-232 typically and accepts the download and loads the code into memory
