By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light

EDVAC Project origin and plan ENIAC inventors John Mauchly and J. Presper Eckert proposed the EDVAC’s construction in August 1944‚ and design work for the EDVAC commenced before the ENIAC was fully operational. The design would implement a number of important architectural and logical improvements conceived during the ENIAC’s construction and would incorporate a high speed serial access memory.[1] Like the ENIAC‚ the EDVAC was built for the U.S. Army’s Ballistics Research Laboratory at the Aberdeen

of p-type and n-type metal oxide semiconductor field effect transistors (MOSFETs) for logic functions. Two important characteristics of CMOS devices are high noise immunity and low static power consumption. Significant power is only drawn while the transistors in the CMOS device are switching between on and off states. Consequently‚ CMOS devices do not produce as much waste heat as other forms of logic‚ for example transistor-transistor logic (TTL) or NMOS logic‚ which uses all n-channel devices

first-generation computer. | The Second Generation: 1956 to 1963 Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 50s. The transistor was far superior to the vacuum tube‚ allowing computers to become smaller‚ faster‚ cheaper‚ more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the

The cost of making electronics was greatly reduced due to the integrated circuit‚ which impacted the designs of all future computers and other electronics. AMD and Intel‚ two major microprocessor companies‚ dominate computers of today. The latest available offerings from Intel as an example contains transistors into the billions

The Astable Multivibrator is another type of cross-coupled transistor switching circuit that has NOstable output states as it changes from one state to the other all the time. The astable circuit consists of two switching transistors‚ a cross-coupled feedback network‚ and two time delay capacitors which allows oscillation between the two states with no external trigger signal to produce the change
