Function of digital computer A typical digital computer system has four basic functional elements: (1) input-output equipment. (2) main memory. (3) control unit. (4) arithmetic-logic unit. Any of a number of devices is used to enter data and program instructions into a computer and to gain access to the results of the processing operation. Common input devices include keyboards and optical scanners; output devices include printers and cathode-ray tube and liquid-crystal display monitors

Difference between Analog and Digital Technologies: Analog and digital signals are used to transmit information‚ usually through electric signals. In both these technologies‚ the information‚ such as any audio or video‚ is transformed into electric signals. The difference between analog and digital technologies is that in analog technology‚ information is translated into electric pulses of varying amplitude. In digital technology‚ translation of information is into binary format (zero or one)

Electrical Interview questions Electrical interview question: What is electric traction? Answer: Traction means using the electric power for traction system i.e. for railways‚ trams‚ trolleys etc. electric traction means use of the electricity for all these. Now a day‚ magnetic traction is also used for bullet trains. Basically dc motors are used for electric traction systems. Electrical interview question: How can you start-up the 40w tube lite with 230v AC/DC without using any choke/Coil

control. In this circuit‚ the temperature sensor used is an NTC thermistor‚ i.e. one having a negative temperature coefficient. The value of thermistor resistance at 25°C is about 1 kilo-ohm. Op-amp A1 essentially works as I to V (current-to-voltage) converter and converts temperature variations into voltage variations. To amplify the change in voltage due to change in temperature‚ instrumentation amplifier formed by op-amps A2‚ A3 and A4 is used. Resistor R2 and zener diode D1 combination is used for

Wireless Network A wireless network‚ as its name would suggest‚ is a network of computers and computer peripherals that are connected to each other without wires. This enables ease of communication‚ especially for mobile computing platforms. Further‚ there are a number of other advantages to a wireless network that make them increasingly common in both the workplace and at home. Nearly all wireless networks in the world work on a standard set up by the Institute of Electrical and Electronics

Final draft The significant air pollution problem in the Los Angeles Basin has been one of the most severe environmental issues that concerned the society. Due to the American tradition‚ public transportations are not so commonly used; therefore‚ a majority of the individuals owned a car. The most commonly used transportation is the convenient motor vehicles that are driven everywhere. With the high volume of traffic daily‚ the tremendous amount of air pollution that is produced by highly-polluted
