Curiosity about the naming convention a "d" at the end of executable? realmd, mangosd

[divineforge]

somehow i notice some naming convention a "d" on certain files ilke realmd, mangosd... and mysqld etc.. usually programming naming convention would have some meaning..

well what's the "d" stands for? at the end of the file name?

any clue would be appreciated. thanks
