History of Computer science The early foundations of what would become computer science predate the invention of the modern digital computer. Machines for calculating fixed numerical tasks, such as the abacus, have existed since antiquity. Wilhelm Schickard built the first mechanical calculator in 1623. Charles Babbage designed a difference engine in Victorian times. Around 1900, punch-card machines were introduced. However, all of these machines were constrained to perform a single task, or at best some subset of all possible tasks. During the 1940s, as newer and more powerful computing machines were developed, the term computer came to refer to the machines rather than their human predecessors. As it became clear that computers could be used for more than just mathematical calculations, the field of computer science broadened to study computation in general. Computer science began to be established as a distinct academic discipline in the 1950s and early 1960s, with the creation of the first computer science departments. Since practical computers became available, many applications of computing have become distinct areas of study. Although many initially believed it impossible that computers themselves may actually be a scientific field of study, in the late fifties it gradually became accepted among the greater academic population. It is the now well-known IBM brand that formed part of the computer science revolution during this time. IBM (short for International Business Machines) released the IBM 704 and later the IBM 709 computers, which were widely used during the exploration period of such devices. "Still, working with the IBM [computer] was frustrating...if you had misplaced as much as one letter in one instruction, the program would crash, and you would have to start the whole process over again". During the late 1950s, the computer science discipline was very much in its developmental stages, and such issues were commonplace. Time has seen significant improvements in the usability and effectiveness of computer science technology. Modern society has seen a significant shift from computers which were used solely by experts or professionals to a more widespread user base.

Discuss the advantages and disadvantages of keeping animals in zoos

On Sunday afternoons in every major city many families go to the zoo with kids. They always have a lot of fun, see many rare animals, funny monkeys, tall giraffes, huge elephants and cute koalas. But what is going on with animals? On the one hand, animals are safe in zoos, which means they cannot be hurt in their cages. Secondly, animals have enough food, for example, they can always eat in a zoo, while they may be starving in nature. Furthermore, many poachers kill animals for their skin, fur and meat, but they cannot do it to animals in zoos. What is more, there are many species that are almost exterminated, but zoos help them reproduce and keep their species existing. The last but not least, if the natural habitat of some species is destroyed, ruined or is no longer for living in, zoos make cages that look exactly like the natural habitat. On the other hand, animals are kept away from their natural place of living. For instance, lions can never live in Berlin. Another major disadvantage of keeping animals imprisoned is too much noise and stress for them. Many people come to see them. For example, kids come near the cages and tease them, so they have a very stressful life unlike their natural way of living. Not to mention the fact that animals are not free. They are trapped in their cells like in prisons. In conclusion, there are many advantages and disadvantages of keeping animals in zoos and everyone is to judge by himself. However, before that think about yourself being kept in a cage and being seen just as an amusement!

One Saturday last winter, my best friends Amy, Maria, Greg, Andy and I decided to spend the weekend in my uncle's house. The weather was bad, so we sat in the living room and talked to each other,but,suddenly, the lights went out and we weren't frightened and started to tell scary stories in the dark. There was a bright flash of lightning and we understood that Andy missed. We were very scared, but than listen to a loud snore from the corner of the room. When the lights came back on, we saw that it was

asleep Andy,then we were all very relieved.
