Device

/swɪtʃ/

noun — "the network’s smart connector that keeps data flowing to the right place."

Switch is a network device that connects multiple devices within a LAN and forwards data frames only to the intended destination device, improving efficiency and reducing collisions compared to hubs. Switches operate at the data link layer (Layer 2) and can also function at the network layer (Layer 3) for routing capabilities.

/ˈraʊ.tər/

noun — "the traffic director of a network."

Router is a network device that forwards data packets between computer networks, determining the optimal path for information to travel from a source to a destination. It connects different networks such as LANs, WANs, and the Internet Protocol, managing traffic efficiently to prevent congestion and ensure reliable communication.

/ˌsiː.piːˈiː/

noun — "the device at your home that connects you to the network."

CPE, short for Customer Premises Equipment, refers to the hardware located at the subscriber’s location that interfaces with the service provider’s network. This includes devices such as modems, routers, set-top boxes, and VoIP adapters, enabling end-users to access broadband services, voice, and multimedia delivered via technologies like G.fast, VDSL, or fiber-optic connections.

/ækˈsɛl.əˌrɒm.ɪ.tər/

noun — "the sensor that measures motion and tilt."

Accelerometer is a sensor that measures acceleration forces acting on an object, including both dynamic forces from motion and static forces like gravity. These measurements are used to determine velocity changes, orientation, vibration, and tilt in devices ranging from smartphones to inertial navigation systems. Accelerometers are fundamental components in robotics, aerospace, consumer electronics, and automotive safety systems.

/ˈmɒs ˌfɛt/

noun — "the switch that drives modern electronics."

MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled transistor widely used in digital and analog circuits, including microprocessors, memory devices, power electronics, and RF amplifiers. MOSFETs are a subtype of field-effect transistors (FET) that use an insulated gate to control current flow between the source and drain, offering high input impedance, fast switching, and scalable performance.

/ˈdʒiː ˌɛf ˈiː ˈtiː/

noun — "the voltage-controlled transistor for analog circuits."

JFET (Junction Field-Effect Transistor) is a type of field-effect transistor (FET) that uses a reverse-biased p-n junction to control current flow through a semiconductor channel. Unlike bipolar junction transistors (BJTs), JFETs are voltage-controlled devices, offering high input impedance, low noise, and simple operation, making them ideal for amplifiers, switches, and analog signal processing.

/ˈsiː ˌɛm ˈoʊ ˌɛs/

noun — "the backbone of modern digital circuits."

CMOS (Complementary Metal-Oxide-Semiconductor) is a semiconductor technology widely used for constructing integrated circuits, including microprocessors, memory chips, and analog devices. CMOS circuits utilize complementary pairs of p-type and n-type metal-oxide-semiconductor field-effect transistors (FET) to achieve high efficiency, low static power consumption, and scalability for complex digital logic.

/ˌɡæl iəm ˈɐr səˌnaɪd/

noun — "the high-speed semiconductor of choice for RF and optoelectronics."

GaAs (Gallium Arsenide) is a III-V compound semiconductor widely used in high-frequency, high-speed, and optoelectronic devices. Its direct bandgap of approximately 1.42 eV allows efficient light emission, making it ideal for LEDs, laser diodes, photodetectors, and solar cells. Additionally, its high electron mobility and saturation velocity outperform silicon in radio frequency (RF) and microwave applications.

/ˌæl ɡæ əˈs/

noun — "the tunable semiconductor for optoelectronics."

AlGaAs (Aluminum Gallium Arsenide) is a compound semiconductor formed by combining aluminum arsenide (AlAs) and gallium arsenide (GaAs). By adjusting the relative composition of aluminum and gallium, engineers can precisely control the material’s bandgap, lattice constant, and optical properties. This tunability makes AlGaAs widely used in high-speed electronics, light-emitting diodes (LED), laser diodes, and photovoltaic devices.

/ɡæn/

noun — "the semiconductor powering high-efficiency electronics."
