Oscilloscope _ An oscilloscope (also known as a scope‚ CRO‚ DSO or‚ an O-scope) is a type of electronic test instrument that allows observation of constantly varying signal voltages‚ usually as a two-dimensional graph of one or more electrical potential differences using the vertical or ’Y’ axis‚ plotted as a function of time‚ (horizontal or ’x’ axis). Although an oscilloscope displays voltage on its vertical axis‚ any other quantity that can be converted to a voltage can be displayed as well

Current is a flow of electrical charge carriers‚ usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere‚ symbolized by A. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current. Electrons

John von Neumann was a Hungarian-American pure and applied mathematician‚ physicist‚ and polymath. He made major contributions to a number of fields‚ including mathematics‚ physics‚ economics‚ computing and statistics. The basic concept behind the von Neumann architecture is the ability to store program instructions in memory along with the data on which those instructions operate. The von Neumann machine was developed by John Von Neumann and others in the 1940s that allow for input‚ output‚ processing
