I need array assistance.

After downloading to the hardware the sketch program says:
Binary sketch size: 2,486 bytes (of a 32,256 byte maximum)

On the page for the Ethernet board:

Memory

The ATmega328 has 32 KB (with 0.5 KB used for the bootloader). It also has 2 KB of SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM library).

so am i limited to 2k for data?
