Shared Objects and Dynamic Link Libraries

[Soubhik Bhattacharya]

hi!
i have to ask something which is very trivial to many of you...
what is the basic difference between shared objects and dynamic link
libraries (if there's any)? it'll be highly appreciated if you refer me to
good online documentations for libraries, linkers and binary formats
(relocatable, static, shared, elf, coeff, a.out etc etc).....
regards,
soubhik.
