Internet
There is a wealth of information online about everything you could possibly imagine. Search engines such as Google, Bing and Yahoo can direct you to relevant information in seconds. Some websites can provide detailed statistics and facts about your research subject, providing you with hard evidence. Other sources on the web can provide expert opinions on subjects that can give your piece a different critical viewpoint and form new arguments that you might not have thought of. Take care to confirm what you are reading is accurate before trusting it as fact.

Use of computers in education and research has completely changed the way things were made before. For example, a lecture to the students or the presentation of a paper to a Congress are completely different with respect to those of only a few decades ago, when blackboard, transparencies or photographic slides were used.

On the other hand as any other appliance it has its own minuses. Let’s face the problem that computer becomes old – fashioned very fast after buying it and needs to be replaced. The point is that replacing a computer is quite expensive. The newer the computer is the more you have to pay for it. Not to mention, the costs you have to pay for fixing the computer if it breaks. In any case, not many people can fix computers so they demand quite a lot of money for repairing them. And computer may have to be fixed if it catches a virus for example. Viruses are all over the Internet; in fact your computer can easily get infected by simply entering some insecure web site. Viruses may cause lots of harm to your computer. They can even destroy all information stored on the computer. That’s why it is very dangerous and you have to...
