advanced features have been added to mail programs and many have been released at low cost Eudora Pro is an example. Email is a low-cost instant information carrier. It can be used internally or on the Internet and will continue to expand in usage. 2. Telnet--This program allows the user to log onto other computers in distant locations and to operate those computers from their own terminal, running systems or downloading data. This defines how omputers speak to each other for login applications. Of course, most computers require a password to be able to access their information. The use of telnet to open other computers has spawned a rash of hacking, which attempts to forge passwords for unauthorized access. These can be criminal acts and are the very situations seen on occasional newscasts! Telnet is available on a public domain basis and can operate with almost all computer hardware. 3. FTP-This allows you to transfer files from one computer to another or from one remote site to another remote site. The user has the ability to download files from shareware servers or from private files using a password for entry. FTP can download small files and huge databases. It is the primary method for those doing research or fact finding to acquire massive amounts of information in a very short time. as was mentioned previously, the time it takes to download files is directly related to the speed of your modem, or direct connection. This can take a very long time in the case of large files 4. Client/server--Much of the current use of the Internet is to share information. This can happen when one computer accesses another that operates separately and serves information to the client who has logged in. You request another computer to send files to you, the client. In the early days of the Internet, most of these were text files only. One such text-based browse is Lynx, developed at the University of ansas for exploration of the documents on the Internet and the World wide Web(www)Web, for short. www is a system for finding and accessing Internet resources. The Web's most innovative feature is the ability to "point and click"on a text word or graphic to hypertext link you to another Web site holding the information you request. This process allows you to move from one computer to the next hop-scotching across the globe to find the information you seek. By using hypertext-based protocol, the world is at your fingertips in an instant. The Lynx program is only text-based, but later developments brought graphics to the Web search vehicles. In order to search the vast reserves of information, browsers were developed. An early public domain browser, developed by the National Center for Supercomputing Applications, is Mosaic. Mosaic is all you need for Web site access. Later, Netscape Navigator was commercially developed with lots of bells and whistles for quick and easy access. There is a cost for Send/Receive Capacity Computers function using binary numbers. This series of 0 or 1 format exists at the smallest level as a bit. This digital system is transmitted over modems or direct connections in a series of 8-bit packets called bytes. Th number of bits per second that can be transmitted or received equates to the speed at which you can send receive information over the Internet. This bandwidth of the transmission line is expressed in bits per second, normally in metric form. Early computer connects were made at 56 bits per second(56 bps). As the speed of machine and systems proved, rates of transmission have increased to kilobits( kbs), megabits(mps), gigabits(gbs), and so on. Early modems operated at 14.4 kbs(14,000 bps), more modern modems function at 28.8 kbs(28, 800 bps) Higher capacity"pipelines"include Integrated Services Digital Network(ISDN) lines that can now be installed at home or business that operate at 56 kbs, direct Ethernet connections(a technology that can connect computers at a 10 Mbps). Higher capacity lines such as T-1(1.54 Mbs)and multiples of those, T-2, and T-3 lines are now being used for extremely high capacity systems. The T-1 and higher lines are very expensive to install and maintain but offer extremely quick Internet work speed Logi In order to begin the process of logging in, you will need an account of some kind.
