Can any one tell me why AES encryption Algorithm is more efficient to use than RSA Algorithm in case of encryption large block size of data ?
thanks in advance ..

RSA is very computationally expensive by comparison with AES. It involves mathematics with very large numbers, whilst AES can be implemented with relatively simple bit operations. The larger the data, the more you feel the pain.
A good compromise is to use RSA to encrypt the symmetric key that is then used in AES encryption of the larger data.
