Wireless access point. In computer networking, a wireless access point, or more generally just access point ( AP ), is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a router or router, but, in a wireless ...
Access Point Name. An Access Point Name ( APN) is the name of a gateway [ 1] between a mobile network ( GSM, GPRS, 3G, 4G and 5G) and another computer network, frequently the public Internet. [ 2] A mobile device making a data connection must be configured with an APN to present to the carrier. The carrier will then examine this identifier to ...
A wireless distribution system ( WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them. The notable advantage of WDS over other solutions is that it preserves ...
OPC Data Access is a group of client–server standards that provides specifications for communicating real-time data from data acquisition devices such as PLCs to display and interface devices like Human–Machine Interfaces (HMI), SCADA systems [ 2] and also ERP / MES systems. [ 3] The specifications focus on the continuous communication of data.

Rogue access point. A rogue access point is a wireless access point that has been installed on a secure network without explicit authorization from a local network administrator, [1] whether added by a well-meaning employee or by a malicious attacker.
A Service Access Point ( SAP) is an identifying label for network endpoints used in Open Systems Interconnection (OSI) networking. The SAP is a conceptual location at which one OSI layer can request the services of another OSI layer. As an example, PD-SAP or PLME-SAP in IEEE 802.15.4 can be mentioned, where the medium access control (MAC) layer ...
In computer systems security, role-based access control ( RBAC) [ 1][ 2] or role-based security[ 3] is an approach to restricting system access to authorized users, and to implementing mandatory access control (MAC) or discretionary access control (DAC). Role-based access control is a policy-neutral access control mechanism defined around roles ...
