Power is supplied as a common-mode signal over two or more of the differential pairs of wires found in the Ethernet cables and comes from a power supply within a PoE-providing networking device, such as an Ethernet switch, or by a PoE injector, a PoE power source that can be used in combination with a non-PoE switch.
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
Solid core cable is intended for permanently installed runs (permanent link). It is less flexible than stranded cable and is more prone to failure if repeatedly flexed due to work hardening. Stranded cable is used at patch panels and for connections from wall ports to end devices (patch cord or drop cable), as it resists cracking of the conductors.
PSLV Orbital Experiment Platform (POEM) also known as PSLV Stage 4 Orbital Platform (PS4-OP) [1] is an orbital micro-gravity test bed based on spent fourth stage of PSLV.By adding modular subsystems for power generation, communication and stabilization like photovoltaic cells, Telemetry and Telecommand (TT&C) package, attitude control system, data storage etc to the PSLV fourth stage, it can ...
A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys. A TPM 2.0 implementation is part of the Windows 11 system requirements. [1]
The pintle injector is a type of propellant injector for a bipropellant rocket engine. Like any other injector, its purpose is to ensure appropriate flow rate and intermixing of the propellants as they are forcibly injected under high pressure into the combustion chamber , so that an efficient and controlled combustion process can happen.

The injector is located in the combustion chamber, inlet manifold or – less commonly – the throttle body. Fuel injectors which also control the metering are called injection valves , while injectors that perform all three functions are called unit injectors .
