An extranet is a controlled private computer network that allows communication with business partners, vendors and suppliers or an authorized set of customers. It extends intranet to trusted outsiders. It provides access to needed services for authorized parties, without granting access to an organization's entire network.
A network interface controller (NIC) is computer hardware that connects the computer to the network media and has the ability to process low-level network information. For example, the NIC may have a connector for plugging in a cable, or an aerial for wireless transmission and reception, and the associated circuitry.
Computer networks engineering is the field dedicated to the design, development and management of interconnected computer systems that facilitate data communication and resource sharing. It encompasses protocols, hardware, and software to ensure reliable and secure connectivity.
An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
A cross-domain solution (CDS) is an integrated information assurance system composed of specialized software or hardware that provides a controlled interface to manually or automatically enable and/or restrict the access or transfer of information between two or more security domains based on a predetermined security policy.
Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
Planners may also consider whether the input of new data and updating of existing data is to be centrally controlled or devolve. These decisions sit alongside to the hardware and software considerations (like content management systems), participation issues (like good taste, harassment, confidentiality), and features to be supported.
