How is a video represented on a computer?

Do you want a low-level analysis of how video images are stored in files, or are you just asking how it's going to look in My Computer/Windows Explorer?

Let's hope it's the latter.......video files are recognisable by their extensions (.AVI, .MP4, .MOV, .MPG, etc.)......there are a great many of them, and those examples in brackets there are just some of the more popular ones. If you've found a file and don't know whether it's a video file or not, you can (a) double-click on it just to see what happens, or (b) google-search for the extension and you'll get some info back on what sort of file it is (particularly if you include the word 'extension' in your search).

What is the difference between mechatronics and electronics and instrumentation engineering?

Hi

i am an alumni of IIT- Kanpur (electronics and instrumentation ). I'm now in imperial college , London pursuing my MEng in artificial intelligence . well basically , there is NO difference between instrumentation and mechatronics . in India , institutes like the IIT's and BITS , NIT's and the VTU affiliated institutes call it instrumentation tech . some prestigious institutes affiliated to Anna university call it mechatronics . other deemed , private and under achieving universities like manipal , srm etc call it mechatronics . regarding the scope of instrumentation , there is not much scope for instrumentation there in India . but here in the UK and other countries like the US , Germany etc , the scope is intense . so for all those who might tend to give it a second thought , please don't . the scope is just too good .

Can you store a 12v battery on the ground?

yes but they should not be left out in cold weather

and keep them away from any heat source or sparks like from welding etc

if charging the battery the acid caps should be loosened to allow excess gas vent

The terms listd on the left are commonly used in reference to electronic records management?

rights - the authority to carry out a particular action permissions - granted or denied by the owner of a file or folder child - subfolder, which usually inherits rights and permissions from the parent folder parent - the root (promary) folder in a structure

What is rt in electronics?

I believe that is resistor transistor technology TTL transistor transistor logic

What is relationship between load and frequency?

Speaking in plain english:

as load increases, frequency decreases and vice versa.

To understand it technically, you need to know what lenz's law and faraday's law of electromagnetic induction is.

For a generator, as load (current drawn) increases, opposing (len's law) electromagnetic induced emf (faraday's law) in generator windings increases and hence it opposes the movement of prime mover. Thus the speed (rpm) of rotor decreases and hence the frequency of generated power output.

Is Breitling A13050.1 watch battery operated?

No, it is a manually wound or automatic (kenetic) movement.

What is the difference between a electronics engineering technology occupational associate's degree and a electronics engineering associate's degree?

Typically, the occupational associates is designed to give the student all the expertise necessary to enter the workforce in entry level positions immediately after completion of the degree. The engineering associates is designed for transfer to a four year college or university for the bachelor's degree. However, it depends on the institution their approach and intent particular to each degree.

What is derating factor of battery?

batteries derating factor will change ,depends upon the temperature& cable size which arelinked with batteries bank.

How much should lemonade be at a lemonade stand if the cause is to gather money to make a electronics show?

Even though its not that much people aren't going to but it if it's too much.

You are going to get more customers if the cost is less.

How many transistors used in core 2 quad and in core 2 duo?

From an AnandTech article the answer appears to be 582 million transistors for the Quad, 291 million for the Duo. Reference: http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2866

What are K maps in digital electronics?

k map is karnaugh map . it is just a method to simplify or minimize the boolean equations so that it becomes easier to realize a circuit using minimum no. of gates.

Can the use of a violet wand cause damage to other electronic equipment with in a home?

Being a device that discharges voltage (even a small amount of electon flow, commonly called amperage) can disrupt or damage electonics. Extent would depend on the amount of VA (voltamps) as well as the particular electronics in question (how well it is grounded, shielded, what sensitive components exposed and other variables). Even without direct current flow any electronic 'generator' creates EMF (electromagnetic force) which can affect (such as RF (radio frequency)) or any component within a certain area that is susceptible to EMF. All this said, with 'normal' usage (read: no direct contact or extreme close proximity) MOST (read: well designed and produced) electronics are not affected within a building (household). I wouldn't use one on myself if I had a pacemaker though (disclaimer: I am not a doctor or engineer). Always use common sense and care when using any electronic device that could potentially injure or damage!

How can you make an electronic device that will buzz only if you separate it from the base unit to a distance after 3 meters probably work using frequency?

To create a device such as this one would chose a freguency is of a clear band width (avoid the upper frequency FM range) and mke the transmitter sufficiently weak that the signal would practically fade out in 3 meters. It is also possible to check the signal strength on the receiving circuit though this is prbably more sophisticated then need be as if you sufficiently under power, via gues nd check you should obtain the desired range.

What are those packs found inside electronics boxes that warn Do Not Eat?

A chemical used to absorb moisture. It is silica gel. It absorbs moisture. The following is from a poison control site: ''Question'': What is harmful about silica gel? ''Answer'': Silica gel is not toxic to humans. There is a warning sign on the packaging because it is considered a choking hazard. If children accidentally ingest silica gel, gently wipe out their mouth and give them something to drink to take away the bad taste. It's called desiccant. Do not eat iPod Shuffle. (sorry, BS answer, I know, but couldn't resist) Actually, it's a desiccant of some sort. A desiccant absorbs moisture so that whatever it's packed with will have reduced exposure to said moisture, thus helping to keep metal from rusting, pills from ruining, and electronics from shorting out. (Wikipedia) A desiccant is a substance that adsorbs water. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture

Why would a car be completely dead with no lights electronics or ignition after it was just running fine?

The only thing that comes to mind in a situation where a car that was running a short time ago and now is COMPLETELY DEAD is a failure of the battery or the primary cables/connections. I'd begin by checking the cable connections at the ends on the battery. The ends at the battery are more prone to failure than the other ends, but check both ends of the cables starting at the battery side. One would be wise to do this with caution, or, if lacking sufficient expertise, with some help.

Is it worth to study CIMA as an additional qualification for an electronic engineer?

Not worth just studying it, but if you can pass it through, you will have feather in your cap. CIMA syllabus is robust and specifically designed for business need, which will definitely add value to your career.

Are Passive reflectors used in both Active and passive Satellite system?

Yes. The most common antenna for satellite systems is the 'Dish'.
The dish is a parabolic , passive, reflector.
It merely reflects and concentrates the signal to the LNB receiver.
Transmission also works this way, bouncing the signal off the dish, to concentrate it in one direction, in a narrow beam.
