Which concept explained in the paragraph below means that data always remains consistent? Specific programs have some tasks that a computer must perform In parallel with others. These tasks (such as the performance of the same set of operations on different data sets) often work in parallel clusters. In such cases, a separate thread of execution handles each separate task You can think of a thread as a sequence of instructions that computers can manage Independently. It is possible for different threads to access the same data elements and change their values, and this can lead to an inconsistent state of Information. For instance, If multiple programs access a shared variable x and change its value, the variable will not contain the correct value at the end of the programs. We can prevent such inconsistencles by using locks. A thread puts a lock on shared data, and releases this lock only after completing its operations.

Read this excerpt from helen keller’s autobiography, the story of my life. have you ever been at sea in a dense fog, when it seemed as if a tangible white darkness shut you in, and the great ship, tense and anxious, groped her way toward the shore with plummet and sounding-line, and you waited with beating heart for something to happen? i was like that ship before my education began, only i was without compass or sounding-line, and had no way of knowing how near the harbour was. "light! give me light! " was the wordless cry of my soul, and the light of love shone on me in that very hour. . the morning after my teacher came she led me into her room and gave me a doll. the little blind children at the perkins institution had sent it and laura bridgman had dressed it; but i did not know this until afterward. when i had played with it a little while, miss sullivan slowly spelled into my hand the word "d-o-l-l." i was at once interested in this finger play and tried to imitate it. when i finally succeeded in making the letters correctly i was flushed with childish pleasure and pride. running downstairs to my mother i held up my hand and made the letters for doll. i did not know that i was spelling a word or even that words existed; i was simply making my fingers go in monkey-like imitation. in the days that followed i learned to spell in this uncomprehending way a great many words, among them pin, hat, cup and a few verbs like sit, stand and walk. based on this excerpt, which words best describe helen keller?
