Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components. Analog circuitry is constructed from two fundamental building blocks: series and parallel circuits. Sometimes it may be difficult to differentiate between analog and digital circuits as they have elements of both linear and non-linear operation. The following list of electronic components focuses on the discrete version of these components, treating such packages as components in their own right. An organization's department dealing with the latest technology in their projects, may also be considered a high-tech microsociety within the organization's and partners' scope.
Analog electronic circuits are those in which current or voltage may vary continuously with time to correspond to the information being represented. Digital circuits therefore can provide both logic and memory, enabling them to perform arbitrary computational functions. As digital circuits become more complex, issues of time delay, logic races, power dissipation, non-ideal switching, on-chip and inter-chip loading, and leakage currents, become limitations to the density, speed and performance. Transistors interconnected so as to provide positive feedback are used as latches and flip flops, circuits that have two or more metastable states, and remain in one of these states until changed by an external input. Today, most electronic devices use semiconductor components to perform electron control.
Wires are usually treated as ideal zero-voltage interconnections; any resistance or reactance is captured by explicitly adding a parasitic element, such as a discrete resistor or inductor.

Digital circuitry is used to create general purpose computing chips, such as microprocessors, and custom-designed logic circuits, known as application-specific integrated circuit (ASICs).
