Why should organisations back up their data?
To prevent data loss - by having multiple copies, even if one copy were to be destroyed in an accident, lost, or changed accidentally, there will still be another copy. It's also a good way to stop vandalism to data.

What 0V stands for in electronics?
Zero Volts, Ground, or Earth. All current flows to this. It stand for NO POTENTIAL. A ground can be elevated to 100v that is the return for that particular circuit sitting 100 volts from earth.
What is LCD tv principal of operation?

It probably isn't a relay- what you will most probably have is bad battery connections, a bad ground, or bad connections/w fusible link down on the starter.
You should better buy MW 3 or battlefield 3. both are too good.
How are electronic volumes measured?
electronic volume can be measured by using transducer transducer is a device which convert non electrical signal to electrical signal. First you need a microphone which is a transducer after that apply the sound vibration on this microphone it will produce a voltage the voltage is directly proportional to applied sound volume level. it measure in decibel.
Why are lead-free electronics superior to electronics manufactured with leaded solders and finishes?
Because this question is not true. One test answer the correct answer was no correct answer

Where can one buy tools for electronic calculators?

What is the benefit of wire being arranged in a zigzag pattern?
Resistance wire is sometimes arranged in a ziz zag pattern. To get the required length of wire for a given resistance, it takes up room and also gives out heat. If it were wound closely, it woould overheat and burn up. The zig zag pattern makes sure that air can pass aound easily, keeping the temperature within limits. Whether that is intentional heat, as in a 'heater' or consequential, as in a motor control resistance, the arrangement is the same.
Describe electronic storefronts and e-malls?
An electronic storefront is the Web-equivalent of a showroom or a physical store. Through the electronic storefront, an e-business can display and/or sell its products. Hundreds of thousands of solo storefronts can be found on the Internet, each with its own Internet name and EC portal. Called electronic storefronts,they may be an extension of physical stores, or they may be new businesses started by entrepreneurs who saw a niche on the Web, such as Amazon.com, CDNow, Uvine.com, and Restaurant.com. Besides being used by retailers, such as Officedepot.com, storefronts also are used by manufacturers, such as Dell.com. Retailers' and manufacturers' storefronts may sell to individuals and/or to organizations.
An electronic mall, also known as a Cybermall or e-mall, is a collection of individual shops under one Internet address. The basic idea of an electronic mall is the same as that of a regular shopping mall to provide a one-stop shopping place that offers many products and services.
Two types of malls exist. First, there are referral malls, such as hawaii.com. You cannot buy in such a mall, but instead you are transferred to a participating storefront. In the second, more traditional type of mall, such as at store.yahoo.com, you can actually make a purchase. At this type of mall, you might shop from a variety of stores, but are able to make only one purchase transaction at the end

What is Linear system in electronics?
A linear electronic device is one where output is linearly proportional, in some way, to input. An example is an amplifier. A non-linear device is one where the input drives the circuit into some kind of saturation mode. An example is a switch, such as is used in TTL IC's.
I think those are either security or safety locks. I think those are either security or safety locks.
Can a 4.5 volt ac adapter be substituted for a 5 volt ac adapter?
Generally speaking the specified voltage is for the rated current so if used at a lower current a higher voltage will be present at the output. You can expect up to a 20% drop in voltage when loaded. So.. a 4.5 volt source rated at an amp could very well still be putting out more then five volts loaded to a few hundred milliamps. More important to consider is when you are using a high current adapter for a low current device you may be burning it up even though the voltage seams to match.
Finally your device should have a voltage range in which it operates, +10,-20% is typical.
This response is for an AC adapter, DC is a little deeper since there are battery eliminators and battery chargers, and of course with both transformers get warm but smoke and fire is just wrong.
What are the following vacuum tube types - 45 - 80 - 125A - 1C5 - 5Y3 - 5U4 - 12SA6?
45 - triode power amplifier
80 - fullwave rectifier
125A - - can't find data
1C5 - pentode power amplifier
5Y3 - equivalent to 80
5U4 - higher-rated version of 80/5y3
12SA6 - - can't find data - did you mean *12sa7* pentagrid converter
What is the purpose of netbook?
Netbooks are computers that can do limited tasks, such as checking email and Internet searching. They can only run everything on low settings as they aren't designed for much more than simple tasks.
Notebooks (laptops) and tablets (like the iPad) are generally better.
Netbooks are good for surfing the Internet, playing YouTube videos, and other Internet-based things. They will play music from anything, and video too, can play games on them. Netbooks are great computers for taking anywhere or on a vacation because they are so small.
The Intel atom-based netbook is a great little piece of technology. It is lightweight and easy to take anywhere.
The advantage to using a netbook is portability. Normally a netbook is defined as a 9-inch, 10-inch, or 12-inch screen, and having a screen this small makes the overall dimensions just slightly larger than a magazine in footprint. This means that you can easily use them on an airplane in even the most cramped of circumstances and still are able to open them up completely for typing. The interesting thing is that even with these smaller dimensions, most of the manufacturers are still able to keep the keyboard almost as large as a normal laptop keyboard. Another advantage of these netbooks is their amazing battery life.
I am using an Intel atom-based netbook, as it is lightweight and easy to take anywhere you can enjoy reading ebooks, playing games, and work that is associated with your nature of job.
How do electronic document management systems make storing documents easier?
Electronic document management systems allow documents to be stored in a more convenient and paperless digital form. In their digital form, these documents are easily searchable and recoverable as well as more cost effective, as firms do not have to waste money on filing cabinets and folders.
