The document provides a history of immigration to the United States from the 15th century to present day. It describes the various reasons different ethnic groups immigrated, including Germans escaping poverty and religious persecution, Italians fleeing natural disasters and overpopulation, and Chinese migrating during the California Gold Rush of 1848. Ellis Island served as the primary immigration station from 1892 to 1954, where all arrivals were interviewed and given medical exams, with around 2% being denied entry. The Statue of Liberty has long symbolized freedom and opportunity for immigrants arriving in New York Harbor.
Computer and network surveillance involves monitoring computer activity, data stored on hard drives, and data transferred over networks like the Internet. This monitoring can be done covertly by governments, corporations, criminal groups, or individuals, and may or may not be legal depending on authorization. While surveillance allows authorities to maintain control and investigate crimes, many civil rights groups argue increasing surveillance could limit personal freedoms and have led to lawsuits against mass surveillance programs.
The Internet originated in the 1960s from the visionary ideas of researchers who wanted to enable computers to share information. J.C.R. Licklider first proposed a global network in 1962. In 1965, Lawrence Roberts connected two computers over telephone lines, confirming Kleinrock's theory of packet switching. Four computers were connected as ARPANET in 1969 under a DARPA contract, and it continued expanding to include more universities and research organizations. The TCP/IP protocols developed in the 1970s established the Internet's architecture. In the 1980s, NSFNet provided a national backbone and popularized email, FTP, and other services for non-technical users.
The Internet is a global network of interconnected computer networks that uses TCP/IP protocols to connect billions of devices worldwide. It can be accessed almost anywhere using stationary devices like personal computers or mobile devices like phones and game consoles. The immense connectivity of the Internet now makes educational information easily accessible at any level, with both the Internet and World Wide Web playing a major role in formal and informal education.
The document discusses the Internet as a global network of interconnected computer networks that allows thousands of users around the world to access and share information digitally. It describes the Internet as a single, global system that enables anyone with an Internet address to connect to other people, organizations, and websites to engage in various online activities and services. Further, the document states that the Internet allows all users to both transmit and receive information, ideas, and opinions interactively without geographical boundaries or limitations.
The World Wide Web was invented by Tim Berners-Lee in 1989 while working at CERN, a particle physics laboratory based in Switzerland. He proposed a global hypertext project which allowed information to be shared across international networks between scientists. The Web was originally conceived and developed to meet the demand for automated information-sharing between scientists in universities and institutes around the world.
The document defines the Internet as a set of computer networks around the world that are linked together through TCP/IP protocols, allowing thousands of users to access and share binary information. It is commonly described through analogies like a system of interconnected local and national telephone networks. The word "Internet" comes from combining the words "inter" and "net", referring to the connections between networks via gateways that allow any computer on one network to communicate with computers on other networks. To access the Internet, a user connects their computer to a modem and telephone line, which connects them to their provider's computer. The provider's modems are then linked to a host computer that functions as a server, allowing the user's computer to become part
The document defines the Internet as a set of computer networks around the world that are linked together through TCP/IP protocols, allowing thousands of users to access and share binary information. It is commonly described through analogies like a system of local and national telephone networks that form a huge international network. To connect to the Internet, one must first connect their computer to a telephone line via a modem, which then connects to their Internet provider's computer through another modem. The provider's computers are in turn connected to large host computers that function as servers, allowing the client computer access to all the services of the Internet once connected.

15. Non si è mai felicemente sposati..
O si è felici o si è sposati.
16. Il matrimonio non è pretendere, ma dare;
è dimenticarsi, ma non dimenticare;
è vivere fuori di sé, pur rimanendo in sé;
è riservarsi le spine e offrire le rose.
