- 2. Firewall Firewall is the system that prevents computer network in organization from invading. The data that flows in the boundary with the outside so that the third party might not invade through an external network,stealing a glance, the falsification, and the destruction of data and the program be done is observed, and an illegal access should be detected and be intercepted. The system that achieves such a function is a firewall.
- 3. Intranet The intranet applied technology of the Internet to the LAN such as companies. “intra” means that internal. It uses a standard of the TCP/IP, and built networks. I use the same software that it is used on the Internet.
- 4. CGI script CGI is abbreviation of Common Gateway Interface. It is the specifications that decided the things which do transfer when we start a program. It is generally described a language called Perl. I can let both tropism last if I use a CGI script.
- 5. Videoconferences A videoconference is a live connection between people in separate locations for the purpose of communication, usually involving audio and often text as well as video. At its simplest, videoconferencing provides transmission of static images and text between two locations. At its most sophisticated, it provides transmission of full-motion video images and high-quality audio between multiple locations.
