What are the differences between verification and validation?
Validation is the checking of data before processing to ensure that it is acceptable for it or not. E.g. When entering a date, the validation for month is 1-12, you cannot enter 13, its out of range. Similarly a telephone number cannot contain letters.Verification is the checking of data that has been copied from one place to another to ensure that is replaces the original one. E.g. PASSWORD. When you sign up in a site, just like WIKIANSWERS, you have to enter your password twice, the second entry being compared with the first.Example in an a paper if a teacher asks us to cross xheck thats validation and when the teacher checks it again orr a re-check thats verification
What is negative one plus negative eleven?
negative twelve of coarse, just take of the negative out and just say 11 plus 1
What does a negative plus a negative means?
It's just a word-description of the process of adding two negative numbers. It's really easy to do. Just add the two numbers and write the answer with a negative sign.
What do you do when the input and output is a fraction?
If it is a fraction, then it is a fraction. You just have to deal with it!
Is the product of an even number of negative numbers negative?
No. Just try it out with 2, or 4, negative numbers.
Explain why validation cannot stop incorrect information from being entered into a database?
Because it just checks if the wrong data has been entered in the wrong field.
How does javascript validate input?
Since JavaScript is a client-side language, all input will be validated on the client-side. This could be simple validation of forms such as checking if the user-submitted e-mail is actually an email, or if the submitted name doesn't have special characters (!#%) etc. These validations can easily be bypassed by manipulating the javascript, so it's not safe. Typically you would do some validation on the server-side just to be safe when storing to a database.
My dazzle says theres no input signal?
i had this problem maybe you should just check your wires or buy new or just buy new cap
What is a data validation on a data base?
Basically its used normally at point of input. I.e when the user enters data. The field is set to accept a certain type of data for example a date. the format is dd/mm/yyyy (European format). In most systems you can set the date input format automatically however, the validation is the the date in a programmed field can be the format entry and if its different to that shown for instance 12/03/15 the entry is not valid and a warning can be shown. . The validation would also be =>DATE. date being the day of use. Again the validation would fail if I tried to input yesterdays date. Common ones are inputs which cannot be greater than a certain figure, start dates must not be greater than end dates to name just some. inputs masks such as the dat format are also used to great effect for telepone numbers, zip/post codes and of course dates
If the input resistor is 3k ohms and the feedback resistor is 33k ohms in an inverting amplifier what is the voltage gain?
If the input resistor is 3k ohms and the feedback resistor is 33k ohms in an inverting amplifier the voltage gain is -11, the ratio of 33 over 3. Consider this... The negative input terminal is a virtual ground, assuming that the positive terminal is tied to ground (usually) through a resistor. That means you have a simple voltage divider between output and input, and the output will be whatever it takes to get the common point (the negative input) to be zero. From there, its all just Ohm's law.
How is science different than religion?
Science requires objective validation, not just words.
When you enter your password for the first time you are asked to enter it twice What is this process called and why do you do it?
THEY DO THAT SO THEY CAN VERIFY YOUR PASSWORD. jUST THINK OF IT THIS WAY THE COMPUTER IS TRYING TO SAVE YOUR PASSWORD IN THE HARDRIVE SO IF YOU CHANE COMPUTERS NOT HARDRIVES IT WILL BE IN THERE, ALSO THE COMPUTER IS NOT FAMILIER WITH IT. Its called validation. The page or program is validating one to the other to make sure they match, which means that you didn't mistype it. Passwords are usually unreadable when you input them. Because of this, if you mistype it you cannot tell. Validation help to prevent this.
How a serial parity generator and checker works?
We check the weather the number of bits at the input are odd or even and assign the parity bit to 1 or 0. And we do the same to check weather the output is the same as the input. Now as the probability of 2 bits going wrong and we may be confident enough just by checking one bit .
What if you take a pregnancy test and its negative but you think you have pregnancy symptoms?
You should consider waiting for your period or just go to the doctor to check it out
How do you reset the check engine light on a 1999 Chevrolet Metro?
If it's like the 1997, you just have to discontinue the negative cable from the battery.

Is a trackball an input or output hardware?
its an input hardware just like a mouse or keyboard
