Paging is a memory management technique in which process address space is broken into blocks of the same size called pages.

Because there is no need address traansaction between processor and peripheral device but data bus is needed because data has to be read and write

Yes, using the realloc() function as shown below:

main()

{

        int *p;

        p = ( int *) malloc (20) ;

        t = p;

        t = (int *) realloc ( p, 40);

        if ( t == NULL )

        Printf (" Cannot reallocate, leaves previous allocated region unchanged ");

       else

       {

              if ( p ==t )

              ;  / * the array expanded at the same region */

             else

            { 

                 free ( p ); / * deallocate the original array */

                 p = t;  /* set p to newly allocated region */

             }

      }

}  

The Von Hippel Award, the Materials Research Society's highest honor, recognizes those qualities most prized by materials scientists and engineers—brilliance and originality of intellect, combined with vision that transcends the boundaries of conventional scientific disciplines. The Von Hippel Award is named after Arthur von Hippel (1898-2003), who was a pioneer in the study of dielectrics, semiconductors, ferromagnetics and ferroelectrics.

Eminent Scientist and Bharat Ratna Prof C.N.R. Rao was awarded 2017 Von Hippel Award. He is first Indian and first Asian to win this honour. The award will be presented to Prof Rao for his interdisciplinary contributions to development of novel functional materials, including nanomaterials, graphene, superconductivity, 2D materials and colossal magnetoresistance at Boston in November 2017.

The persons with 'O' blood group do not have antigens in the red corpuscles. So that blood will not cause agglutination of corpuscles if mixed with any type of blood. So group 'O' persons are called universal donors.
