What is the Internet?

Each definition of the Internet is a simplified statement and runs the risk of being outdated within a short time. What is usually referred to as the Internet is a network of thousands of computer networks (so called autonomous systems) run by governmental authorities, companies, and universities, etc. Generally speaking, every time a user connects to a computer networks, a new Internet is created. Technically speaking, the Internet is a wide area network (WAN) that may be connected to local area networks (LANs).

What constitutes the Internet is constantly changing. Certainly the state of the future Net will be different to the present one. Some years ago the Internet could still be described as a network of computer networks using a common communication protocol, the so-called IP protocol. Today, however, networks using other communication protocols are also connected to other networks via gateways.

Also, the Internet is not solely constituted by computers connected to other computers, because there are also point-of-sale terminals, cameras, robots, telescopes, cellular phones, TV sets and and an assortment of other hardware components that are connected to the Internet.

At the core of the Internet are so-called Internet exchanges, national backbone networks, regional networks, and local networks.

Since these networks are often privately owned, any description of the Internet as a public network is not an accurate. It is easier to say what the Internet is not than to say what it is. On 24 October, 1995 the U.S. Federal Networking Council made the following resolution concerning the definition of the term "Internet": "Internet" refers to the global information system that (i) is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons; (ii) is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols; and (iii) provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein."

What is generally and in a simplyfiying manner called the Internet, may be better referred to as the Matrix, a term introduced by science fiction writer William Gibson, as John S. Quarterman and Smoot Carl-Mitchell have proposed. The Matrix consists of all computer systems worldwide capable of exchanging E-Mail: of the USENET, corporate networks and proprietary networks owned by telecommunication and cable TV companies.

Strictly speaking, the Matrix is not a medium; it is a platform for resources: for media and services. The Matrix is mainly a very powerful means for making information easily accessible worldwide, for sending and receiving messages, videos, texts and audio files, for transferring funds and trading securities, for sharing resources, for collecting weather condition data, for trailing the movements of elephants, for playing games online, for video conferencing, for distance learning, for virtual exhibitions, for jamming with other musicians, for long distance ordering, for auctions, for tracking packaged goods, for doing business, for chatting, and for remote access of computers and devices as telescopes and robots remotely, e. g. The Internet is a wonderful tool for exchanging, retrieving, and storing data and sharing equipment over long distances and eventually real-time, if telecommunication infrastructure is reliable and of high quality.

Biometric applications: surveillance

Biometric technologies are not surveillance technologies in themselves, but as identification technologies they provide an input into surveillance which can make such as face recognition are combined with camera systems and criminal data banks in order to supervise public places and single out individuals.

Another example is the use of biometrics technologies is in the supervision of probationers, who in this way can carry their special hybrid status between imprisonment and freedom with them, so that they can be tracked down easily.

Unlike biometric applications in access control, where one is aware of the biometric data extraction process, what makes biometrics used in surveillance a particularly critical issue is the fact that biometric samples are extracted routinely, unnoticed by the individuals concerned.

Late 1950s - Early 1960s: Second Generation Computers

An important change in the development of computers occurred in 1948 with the invention of the transistor. It replaced the large, unwieldy vacuum tube and as a result led to a shrinking in size of electronic machinery. The transistor was first applied to a computer in 1956. Combined with the advances in magnetic-core memory, the use of transistors resulted in computers that were smaller, faster, more reliable and more energy-efficient than their predecessors.

Stretch by IBM and LARC by Sperry-Rand (1959) were the first large-scale machines to take advantage of the transistor technology (and also used assembly language instead of the difficult machine language). Both developed for atomic energy laboratories could handle enormous amounts of data, but still were costly and too powerful for the business sector's needs. Therefore only two LARC's were ever installed.

Throughout the early 1960s there were a number of commercially successful computers (for example the IBM 1401) used in business, universities, and government and by 1965 most large firms routinely processed financial information by using computers. Decisive for the success of computers in business was the stored program concept and the development of sophisticated high-level programming languages like FORTRAN (Formular Translator), 1956, and COBOL (Common Business-Oriented Language), 1960, that gave them the flexibility to be cost effective and productive. The invention of second generation computers also marked the beginning of an entire branch, the software industry, and the birth of a wide range of new types of careers.

David Kahn

David Kahn can be considered one of the most important historians on cryptography. His book The Codebreakers. The comprehensive history of secret Communication from Ancient Times to the Internet, written in 1996 is supposed to be the most important work on the history of cryptography.

First Amendment Handbook

The First Amendment to the US Constitution, though short, lists a number of rights. Only a handful of words refer to freedoms of speech and the press, but those words are of incalculable significance. To understand the current subtleties and controversies surrounding this right, check out this First Amendment site. This detailed handbook of legal information, mostly intended for journalists, should be of interest to anyone who reads or writes. For example, the chapter Invasion of Privacy shows the limits of First Amendment rights, and the balance between the rights of the individual and the rights of the public - or, more crudely, the balance of Tabloid vs. Celebrity. Each section is carefully emended with relevant legal decisions.
