By the beginning of the 21st century, approximately 360 million people, or roughly 6 percent of the world’s population, were estimated to have access to the Internet.
The Internet provides a capability so powerful and general that it can be used for almost any purpose that depends on information, and it is accessible by every individual who connects to one of its constituent networks.
It supports human communication via electronic mail (e-mail), “chat rooms,” newsgroups, and audio and video transmission and allows people to work collaboratively at many different locations.
These ideas were first realized in United States, and it soon became a critical piece of infrastructure for the computer science research community in the United States.
Tools and applications—such as the simple mail transfer protocol (SMTP, commonly referred to as e-mail), for sending short messages, and the file transfer protocol (FTP), for longer transmissions—quickly emerged.
Time-sharing systems allowed a computer’s resources to be shared in rapid succession with multiple users, cycling through the queue of users so quickly that the computer appeared dedicated to each user’s tasks despite the existence of many others accessing the system “simultaneously.” This led to the notion of sharing computer resources (called host computers or simply hosts) over an entire network.
Host-to-host interactions were envisioned, along with access to specialized resources (such as supercomputers and mass storage systems) and interactive access by remote users to the computational powers of time-sharing systems located elsewhere.Kim Jameson is a student at a prominent university while Kate Jameson also known as Dominique, Kim's twin sister, is a troubled model working for the House of Shambertin in Paris.
