History of internet

The first internet connection take place in 1957 when everything began, before this year, computers only work on one task at a time, called batch processing. The aim of the first internet systems is time sharing which consists in a good work directly on the computers and the fisrt idea was to share the processing on one computer with a lot of uses. One of the concepts of the Network called Arpanet was Rand corporation in America, the comercial network in England called NPL National Physical Laboratory and the scientific network called Cyclades in France.
Packet switching is an union of IMP, NCP and TCP which control the network activities and verification of the fail transfer and it was necesary because design other comercial bases, had a lot of uses and fail transfers. In 1962 American scientist discovered teh meddle and long ranges in cuba which was be able to rich the United States. In France was born the word inter-net in Cyclades in the comunication with other networks.
By 28 of February in 1990 Arpanet was removed and internet up and running was born.

Are the exams now too difficult?

In Catalunya, the exams are more difficult than other parts of Spain.
In my opinion, doing catalan language is much more difficult than the majority of languages.

First of all, there are a lot of words which people have problems. In addition, the marks of people who went to catalan centers of Batxillerat are better than the other Spanish parts, this is not a coincidence.

Secondly, a lot of people who begins batxillerat, later they failed them and it's too difficult because only point the exams. Furthermore, poeple who have doing scientifics are very stressed every day. Maths, chemestry,... and others.

To sum up, I think that the exams are excessive and very difficults, if anyone studied the last day before the exam, he will probably fail the exam.
