HTTP - Hypertext Transfer Protocol (HTTP) is a method used to transfer or convey information on the World Wide Web. Its original purpose was to provide a way to publish and retrieve HTML pages.
Telnet - TELNET (TELetype NETwork) is a network protocol used on the Internet or local area network (LAN) connections. It was developed in 1969 beginning with RFC#0015 and standardized as IETF STD 8, one of the first Internet standards. It has limitations that are considered to be security risks.
ftp - FTP or File Transfer Protocol is used to transfer data from one computer to another over the Internet, or through a network.
ftp software - Core FTP LE - site to site transfers, FTP transfer resume, drag and drop support, file viewing & editing, firewall support, custom commands, FTP URL parsing, command line transfers, filters.

Work For Today... Modem
What is a modem? A modem (from modulate and demodulate) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used over any means of transmitting analog signals, from driven diodes to radio. Experiments have even been performed in the use of modems over the medium of two cans connected by a string.[citation needed].
Speed: The speeds of modems can vary. For example, modems remained at 300 and 1200 bit/s into the mid 1980s.
What is the most recent standard of traditional modems? The lastest version is V.92.
What is ADSL? Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. It does this by utilizing frequencies that are normally not used by a voice telephone call, in particular, frequencies higher than normal human hearing. This signal will not travel very far over normal telephone cables, so ADSL can only be used over short distances, typically less than 5 km. Once the signal reaches the telephone company's local office, the ADSL signal is stripped off and immediately routed onto a conventional internet network, while any voice-frequency signal is switched into the conventional phone network. This allows a single telephone connection to be used for both ADSL service and voice calls at the same time.

DNS - Domain Name System (DNS) stores and associates many types of information with domain names; most importantly, it translates domain names to IP addresses.
DNS server - and server for the DNS.
WINs - Windows Internet Name Service (WINS) is Microsoft's implementation of NetBIOS Name Server (NBNS) on Windows, a name server and service for NetBIOS computer names.
DHCP - DHCP is a set of rules used by communications devices such as a computer, router or network adapter to allow the device to request and obtain an IP address from a server which has a list of addresses available for assignment.

Protocol - is a convention or standard that controls or enables the connection, communication, and data transfer between two computing endpoints.
communications protocol is the set of standard rules for data representation, signalling, authentication and error detection required to send information over a communications channel.
TCP/IP - set of communications protocols that implements the protocol stack on which the Internet and many commercial networks run.
NIC - A domain name registry, also called Network Information Centre (NIC), is part of the Domain Name System (DNS) of the Internet which converts domain names to IP addresses.
Peer-to-Peer Network Connection - in a peer-to-peer network there are no dedicated servers or hierarchy among the computers. All of the computers on the network handle security and administration for themselves. The users must make the decisions about who gets access to what. Beyond that there are more similarities between the types of network than differences. All of the computers must have network cards. You also use the same cables, the same hubs and switches, and the same protocols as you would with a client-server model. The only difference is that there isn't a server. Since there isn't a server, there are some things to think about before you go down the peer-to-peer path

Work For Today...ERD Commander & Configsafe
ERD Commander - When your server or workstation won't boot, you need ERD Commander 2005. ERD Commander 2005 boots dead systems directly from CD into a Windows-like repair environment. You'll have full access to the dead system's volumes, so you can diagnose and repair problems using tools located on the ERD Commander 2005 Start menu. And you'll have built-in network access to safely move data off of, or on to, the dead system. With ERD Commander 2005 you can repair a system quickly and easily, saving you time and rescuing your critical data.
Configsafe - The schwizex.exe process will monitor your system, watching for changes to your system's registry, ini files, hardware and installation of software. It will periodically keep a copy of your systems configuration so that you can restore the system, should changes cause your computer to become unstable. It can be stopped if causing problems, however if possible you should leave it running.
schwizex.exe is an application that does NOT appear to be a security risk
The Process Server database currently registers schwizex.exe to Imagine.
This is part of ConfigSafe.
The Process Manager database is updated often, but inaccuracies may still exist, often caused by viruses named after valid files such as ConfigSafe. Always verify your results just to play it safe.
