Real-Time Systems
/ˈrɪəl taɪm ˈsɪstəmz/
noun — "systems where being late is the same as being wrong."
Real-Time Systems are computing systems in which the correctness of operation depends not only on logical results but also on the time at which those results are produced. A computation that produces the right answer too late is considered a failure. This timing requirement distinguishes real-time systems from conventional computing systems, where performance delays are typically undesirable but not incorrect.
Embedded Systems
/ɪmˈbɛdɪd ˈsɪstəmz/
noun — "computers that disappear into the machines they control."
Embedded Systems are specialized computing systems designed to perform a single, well-defined function as part of a larger physical or logical system. Unlike general-purpose computers, which are built to run many different applications and adapt to changing workloads, embedded systems are purpose-built. They exist to do one job, do it reliably, and do it repeatedly, often without any direct human interaction once deployed.
Voltage Regulator
/ˈvoʊltɪdʒ ˈrɛɡjəˌleɪtər/
noun … “Circuit that maintains a constant output voltage.”
Voltage Regulator is an electronic circuit or device that automatically maintains a stable output voltage regardless of changes in input voltage, load current, or environmental conditions such as temperature. Voltage regulators are a core component of reliable electronic systems, ensuring that sensitive circuits receive clean, predictable power even when the power source is noisy or fluctuating.
Power Supply
/ˈpaʊər səˌplaɪ/
noun … “System that provides electrical energy in usable form.”
Power Supply is an electrical device or system that delivers controlled electrical power to an electronic load. Its primary role is to convert energy from a source—such as mains electricity, a battery, or a generator—into the specific voltage, current, and stability required by electronic circuits. Power supplies are foundational to all electronic systems, from tiny embedded devices to large data centers.
Sequential Circuit
/sɪˈkwɛnʃəl ˈsɜːrkɪt/
noun … “Logic circuit whose output depends on current and past inputs.”
Integrated Circuit
/ˈɪntɪˌɡreɪtɪd ˈsɜːrkɪt/
noun … “Miniaturized electronic circuit on a semiconductor chip.”
Diode
/ˈdaɪoʊd/
noun … “Semiconductor device that allows current to flow in one direction.”
Diode is a two-terminal electronic component that permits electric current to flow primarily in a single direction while blocking it in the opposite direction. Diodes are fundamental elements in electronic circuits, used for rectification, signal shaping, protection, and voltage regulation. They are built from semiconductor materials, typically silicon, arranged to form a p–n junction.
Combinational Circuit
/ˌkɑːmbɪˈneɪʃənəl ˈsɜːrkɪt/
noun … “Logic circuit with output determined only by current inputs.”
Combinational Circuit is a type of digital logic circuit whose output depends solely on the present values of its inputs, with no reliance on past states or stored memory. Unlike sequential circuits, combinational circuits have no internal state, clock, or feedback loops. They are built entirely from logic gates and implement Boolean expressions directly.
Semiconductor
/ˌsɛmɪkənˈdʌktər/
noun … “Material with controllable electrical conductivity.”
Semiconductor is a material whose electrical conductivity lies between that of a conductor and an insulator. Its conductivity can be modified by adding impurities (doping), applying voltage, or controlling temperature. Semiconductors are the foundation of modern electronics, enabling the creation of transistors, logic gates, diodes, integrated circuits, microprocessors, and memory devices.
Transistor
/ˈtrænzɪstər/
noun … “Semiconductor device for controlling current.”
Transistor is a semiconductor component used to amplify or switch electronic signals and electrical power. It is the fundamental building block of modern electronic devices, including logic gates, microprocessors, memory, and analog circuits. Transistors control current flow through their terminals—typically called the emitter, base, and collector (for bipolar junction transistors) or source, gate, and drain (for field-effect transistors).
