An access device with built-in basic routing protocol support, specifically designed to allow remote network access to corporate backbone networks. Access routers are not designed to replace backbone routers or to build backbone networks. They usually have limited protocols, few ports, and low speed. Access Routers are the first step towards building a better technical support network for your Tampa business.

A high-bandwidth transmission technology that uses light to carry digital information. One fiber-optic cable carries hundreds of thousands of voice or data circuits. These cables, or light guides, replace conventional coaxial cables and wire pairs. Fiber transmission facilities occupy far less physical volume for an equivalent transmission capacity. Optical fiber is also immune to electrical interference.

An application or entire computer, such as an Internet gateway server, that controls access to a network and monitors the flow of network traffic. A firewall can screen and keep out unwanted network traffic and ward off outside intrusion into a private network. This is particularly important when a local network connects to the Internet. Firewalls have become critical applications as use of the Internet has increased.
To have a Firewall or other anti-virus and spyware software or equipment installed in Tampa, FL, call our business IT consulting and tech support firm.

A server designed to transform data streams to better match device capabilities. For example, Wireless Application Protocol gateway servers convert HTML to Wireless Markup Language for wireless devices, and a number of products can reformat HTML for devices, such as mobile phones and smart phones. Today, HTML-based gateway servers predominate. While HTML can be made aware of a unique device requesting content, more often “shadow” Web server applications are created to draw off and reformat the native content.

The primary or controlling system in a multiple-computer network operation. Typically, the term specifically denotes a network-connected computer that hosts services, facilities, or applications used by the other computers or terminals on the same network. For example, a Web host is a computer on which a Web site’s pages are stored.

A methodology for developing an integrated information system based on the sharing of common data, with emphasis on decision support needs as well as transaction-processing requirements. It assumes logical data representations are relatively stable compared with the frequently changing processes that use the data. Therefore, the logical data model, which reflects an organization’s rules and policies, should be the basis for system development.

A geographically limited communication network that connects users within a defined area. A LAN is generally contained within a building or small group of buildings and is managed and owned by a single enterprise. The shorter distances within a building or campus enable faster communications at a lower cost than wide-area networks (WANs). Although an increasing number of LANs use Internet standards and protocols, they are normally protected from the public Internet by firewalls.

Any number of computers (such as PCs and servers) and devices (such as printers and modems) joined together by physical or wireless communications links. In the enterprise context, networks allow information to be passed between computers, regardless of where those computers are located. Networks provide the roads for information traffic (such as sending files and e-mails) within a corporate environment and allow users to access databases and share applications residing on servers. If a network does not go outside of a company building, or campus, then it is known as a Local Area Network (LAN). If it has a bridge to other outside networks, usually via lines owned by public telecommunications carriers, then it is known as a wide-area network (WAN).

An Internet security standard developed by Netscape Communications. SSL offers session-level security — that is, after a secure session has been initiated, all information transmitted over the Internet during that session is encrypted. SSL also offers features such as server and client authentication as well as message integrity.
