@Dinesh: By definition, a brute-force attack is just cycling through all the possible keys. Therefore, in general, greater the bits in the key, the more combinations that require to be tested and hence harder the brute-force attack.

Pfleeger. It has the whole ago and in layman's terms.
Double DES is as secure as DES with 57bit key while Triple DES does give more security.
