What is the difference between ISO and OSI?

ISO is an abbreviation for the International Organization for Standardization. This is known as an Open System Interconnection (OSI) model, or simply the OSI model.

The ISO-OSI model consists of seven layers. In a comprehensive communication system, it defines seven tiers or levels. ISO is an acronym for International Standards Organization, a multinational organization that works to standardize network communication protocols on a global scale. OSI (Open System Interconnection) is a networking communication paradigm developed by ISO.

The OSI Model includes a distinct layer for Data Link and Physical, but TCP/IP has a single Network Interface layer for both. Similarly, in OSI, there are Application, Presentation, and Session levels, which for TCP/IP are integrated into one layer (Application).

Therefore, option B is correct.

And if one of us was, what would the rest of the family do? My sister was indeed momentarily rejected; she had been so ill and had cried so much that her eyes were absolutely bloodshot, and Mother was told, "Well, we cant let her in.

ASAP: Write a Summary of the story "The Brave Little Parrot" 50 points if interested!!Passage: Once, long ago, the Buddha was born as a little parrot. One day a storm fell upon his forest home. Lightning flashed, thunder crashed, and a dead tree, struck by lightning, burst into flames. Sparks leapt on the wind and soon the forest was ablaze. Terrified animals ran wildly in every direction, seeking safety from the flames and smoke."Fire! Fire!" cried the little parrot. "To the river!" Flapping his wings, he flung himself out into the fury of the storm and, rising higher, flew towards the safety of the river. But as he flew he could see that many animals were trapped, surrounded by the flames below, with no chance of escape.Suddenly a desperate idea, a way to save them, came to him. He darted to the river, dipped himself in the water, and flew back over the now raging fire. The heat rising up from the burning forest was like the heat of an oven. The thick smoke made breathing almost unbearable. A wall of flames shot up on one side, and then the other. Crackling flames leapt before him. Twisting and turning through the mad maze of fire, the little parrot flew bravely on. At last, when he was over the center of the forest, he shook his wings and released the few drops of water which still clung to his feathers. The tiny drops tumbled down like jewels into the heart of the blaze and vanished with a hissssssssss.Then the little parrot once more flew back through the flames and smoke to the river, dipped himself in the cool water, and flew back again over the burning forest. Back and forth he flew, time and time again, from the river to the forest, from the burning forest to the river. His feathers were charred. His feet were scorched. His lungs ached. His eyes, stung by smoke, turned red as coals. His mind spun dizzily as the spinning sparks. But still the little parrot flew on.At this time, some of the devasgods of a happy realmwere floating overhead in their cloud palaces of ivory and gold. They happened to look down. And they saw the little parrot flying among the flames. They pointed at him with perfect hands. Between mouthfuls of honeyed foods they exclaimed, "Look at that foolish bird! He's trying to put out a raging forest fire with a few sprinkles of water! How absurd!" And they laughed.But one of those gods, strangely moved, changed himself into a golden eagle and flew down, down towards the little parrot's fiery path.The little parrot was just nearing the flames again when the great eagle with eyes like molten gold appeared at his side. "Go back, little bird!" said the eagle in a solemn and majestic voice. "Your task is hopeless! A few drops of water can't put out a forest fire! Cease now and save yourselfbefore it is too late."But the little parrot only continued to fly on through the smoke and flames. He could hear the great eagle flying above him as the heat grew fiercer, calling out, "Stop, foolish little parrot! Save yourself! Save yourself!"
