It can only understand binary number system which is 0 or 1 . all the information which to be processed is converted to digital after that processing done. it has several advantages like-

high speed, low noise , less error , low power consumption and high reliable.

How physics relates to video games?

Physics in Video GamesPhysics is an integral part of most modern video game design, especially if the game is in three-d. Here are some examples:-Optics (the physics of light) is used to figure out how a scene in a video game might look when lit up, what angles glassy surfaces might reflect at, at what degree a reflection on water is bent, and whether nearby surfaces reflect onto each other and to what degree. It also lets them know what parts and how intensely surfaces are lit, and how different textures and kinds of materials absorb or give off light. This can let them display objects with seemingly different textures, such as a chalky surface vs. a smooth surface.-Kinetics (the physics of movement) has been in play since Pong, although the formulas used to determine movement have grown more refined, and now might take into account gravity, air resistance, or, in a lot of games, the impact from bullets. Kinetics also has special formulas for the movement of springs, which can be useful for figuring out how a vehicle might move over bumpy terrain, or how hair might move during a movie sequence.-Acoustics, the physics of sound, has come into play recently as some games now take advantage of the Doppler effect for added realism- noisy objects getting louder as they get closer and quieter as they move away.-Some space simulations and most flight sims take gravity into account to figure out how quickly a space vehicle or plane should fall towards the surface of the nearest planet. Also, tank and mortar trajectories take these formulas into account.There is another area where physics comes into play, of course, and that is in the design of the video game system itself. Solving problems like keeping the CPU at an appropriate temperature, or storing memory at a given density can make new video games possible that weren't before.Interestingly enough, physics isn't the only science that sometimes has a hand in video game design. Materials science, mathematics, chemistry, and especially information science, all play roles.

Is telephone an electrical device or electronics?

Both. This is synonymous to asking "Is hydrogen an atom or a molecule?"

Does taking a picture take your soul?

No. Never. Never believe that is true. It's not true. Whoever told you that is lying. There is no possible thing on Earth that could take your soul.

How many applications the iPad can run from the app store?

The iPad can run only one app at a time but if you switch apps and go back to the original app (such as Safari) - it will display what you were last doing incase you need to continue that task. However, Apple announced version 4 of the OS iPad uses recently and OS 4 will have multitasking. The iPad will be getting the version 4 update this fall (around October I suspect).

---------

According to the latest Apple's statement iOS 4 for iPad will be available this coming November. With iOS 3.2 iPad is capable of running pre-installed apps such are iPod (you can listen music, while working with any other app, which doesn't play music), Clock (Timer / CountDown), App Store (app downloading and installing process).

When is electronic evidence usually inadmissible?

Electronic or digital evidence is often inadmissible if it was obtained without any authorization whatsoever. Without a warrant even solid evidence can be rendered useless.

Describe consumer electronics?

It is defined as the electronics products which is used for the daily day today life or used by the peoples most frequently used.

What are the disadvantages of electronic media explain briefly?

Television is a good medium of communication that prevents us from communicating with each other. Glued to our seats we watch this one-eyed monster leaving our guests in the room, or turning a deaf ear to our mother's call. Often our food is left uneaten and home work undone. After the Second World War, Barid invented it for us so that we might get knowledge with pleasure. But we have closed our eyes to all kinds of knowledge and have opened up our hearts to all types of vulgar pleasure. Now the children who used to hear stories from their mothers and grandmothers like to see cartoons. Mothers are not in a mood to tell stories about ghosts and fairies.

They are busy in watching Television. But all this does not mean that TV has only bad aspects. Many educational, scientific, historical and political programs that are shown on TV are very interesting and informative. We are taken to any corner of the world where any game of our interest is being played. We are taught how a particular dish is cooked, how a particular disease can be prevented or cured, how our houses can be decorated without spending much money

What would life be without batteries?

we wouldn't have portable things like sell phones

What are bundled conductors?

High-voltage transmission line conductors are 'bundled' -that is, each 'line' comprises two or more conductors, rather than a single conductor, suspended from each insulator chain.

The reason for bundling is to reduce the intensity of the electric field on the surface of the conductors (the same field is shared between the surfaces of several, rather than just one, conductors), which would otherwise result in a breakdown of the insulating property of the air immediately surrounding a single conductor.

In the UK, 400-kV transmission lines use a bundle of four conductors per line, and 275-kV transmission lines use a bundle of two.

How do you get more memory on the Samsung prevail?

When you got your Prevail it should have come with a MicroSD card. You could always try moving programs onto it. If that doesn't work, uninstall programs that are not a necessity. Samsung screwed the Prevail over with little internal memory and tried to make up for it with allowing it to hold a 32GB MicroSD. (Idiots) If neither of the above work for you, you could always try rooting your phone and getting rid of all the "bloat-ware" that came previously installed on your phone. (ie. Layar, Google Books, etc.)

Being an Electronics and Communication Engineering student what's the need for reading Thermodynamics?

Being an Electronics and Communication Engineering student the necessities for studying Thermodynamics are the followings- 1. In many engineering fields like Robotics, while designine circuits, one must take into account the heat produced in the circuit and push them away from the circuit components. 2. While designing any computer controlled air-cooling system, one is to deal with the core things of Thermodynamics. 3. Today's technology is completely turning towards automation system where all types of mechanical and applied science applications need to be converted into programming based/microchip based/wireless communication based system. If one asks to design any microchip for such application, one must have knowledge energy conversion system such as heat; and therefore requires knowledge of thermodynamics. Because, thermodynamics not only deals with heat energy, but also does with all types of energy conversions, their mathematical derivations and important ratios.

What type of soudcard has can be a home theatre receiver?

You can use any sound card that has surround sound outputs along with a surround speaker setup to watch movies in surround sound. No sound card replicates all the functions of an actual receiver, though, as a real receiver will connect your CD player, TV, DVD player and other devices and offer a AM/FM tuner for radio (that's the 'receiver' part of the description).

Is it risky to buy any electronics from niranjan store Singapore?

Very very risky to buy cos I got samsung tab 3 and note 2 three months both got repaired. ..one is having issue with tge battery and another display gone. . Lost 800 sin $ . I think he is selling low quality or rejected electronic goods

Why work at Frys electronics?

Fry's Electronics is a home grown California business. It started as a grocery store, but was changed by the owner's heirs. Not only do they sell computers, they sell components to build your own.

Difference between oscillator and amplifier?

The amplifier projects the audio signal into something we can comprehend.

The oscillator creates a fixed or variable pitch, which is fed to the amplifier.

Amplifiers are circuits which transfer an input signal into an output signal.

Oscillators are autonomous circuits powered by a constant energy source.

They produce a steady state signal e.g. a sinusoidal signal or a chaotic signal.

What is 9.0 volt battery supplying to an energy circuit?

The battery is supplying electrons by a process of chemical reaction.

What is electronic counting of platelets?

There are two types of electronic counting, voltage-pulse and electro-optical counting systems. In both systems, the collected blood is diluted and counted by passing the blood through an electronic counter.

Advantage and disadvantages of avalanche diode?

Avalanche photodiode advantages and disadvantagesThe avalanche photodiode has a number of different characteristics to the normal p-n or p-i-n photodiodes, making them more suitable for use in some applications. In view of this it is worth summarising their advantages and disadvantages..

The main advantages of the avalanche photodiode include:

  • Greater level of sensitivity

The disadvantages of the avalanche photodiode include:

  • Much higher operating voltage may be required.
  • Avalanche photodiode produces a much higher level of noise than a p-n photodiode
  • Avalanche process means that the output is not linear

Is electronics engineering a BA or BS degree?

Bachelor of Science usually. It might also be Bachelor of Engineering, Bachelor of Technology or Bachelor of Applied Science, depending on the school with the major field of study , or "major" in Electrical Engineering or Electrical and Electronic Engineering. Pay careful attention in your math and physics classes if you're interested in getting a BSEE degree Not allengineers are with a BSEE degrees An education does not substitute for experience in the field. A degree is mandatory for some company if involved with design for the government But a small company would Rather hire more on experience as opposed to education. In this field reasoning power is more valuable the formal education.

What is the use of two capacitor with crystal in 8051?

The "requirement" of using two capacitors with the crystal in the 8051 is complicated, and based on many factors, such as series resistance, the design of the parallel resonant feedback circuit, stray or parasitic capacitance, startup stability, etc. Insight can be gained from Intel's Application Note AP-155 but, in the final analysis, from a purely pragmatic standpoint, the requirement is there simply because "Intel says so". Use the circuit from the data sheet.
