I have used malloc function in linklist for allocating dynamic memory to the pointers.In linklist nodes are at random locations.

The communication links across which computers—or parts of computers—talk to one another may be either serial or parallel. A parallel link transmits several streams of data (perhaps representing particular bits of a stream of bytes) along multiple channels (wires, printed … Continue reading →
