Big endian and little endian
"Little Endian" means that the low-order byte of the number is stored in memory at the lowest address, and the high-order byte at the highest address. (The little end comes first.) For example, a 4 byte LongInt

Byte3 Byte2 Byte1 Byte0
[/snippet]

in the above theory I’d mentioned that lower order byte is stored at lowest address for little endian and gave pictorail representation of memory arrangement, so it should not cause any confusion, I guess.
anyways

1024 represented as below in little endian machine

lowest address
                |
                V
00 00 04 00

in big endian it will be represented this way
highest address
|
V
00 04 00 00

thanks siddhuu :-)

Indicate which address is lower and which is Higher address. By writing simply its giving impression that example shown is wrong for big and little indian cases. Ex : 1024 (0×00000400) stored in little endian machine as 00 00 04 00 in big endian machine stored as 00 04 00 00 -----Siddhuu Siddhartha Roy (Bengal Tiger) Please correct this !!

Ex :

1024 (0×00000400) stored in little endian machine

as

00 00 04 00

in big endian machine stored as

00 04 00 00
