what is ascii value?

Answer 1

Of what?

Answer 2

Have you ever tried to find a simple ASCII value table on the web? I did, and it wasn't easy! So I put this one together for myself. I thought others might find it useful too - so here it is.

Answer 3

ASCII - American Standard Code for Information Interchange

Computers do not understand English. They understand only binary codes (that is streams of 0's and 1's). So when we want to use the computer to do deal with text having English characters we cannot expect the computer to understand it. So what we do is, we will change the alphabets to the binary language that computers understand. This is just like translation from one language to another.

The ASCII table gives the values to which each character has to be mapped. For eg, the lower case 'a' has an ASCII value of 97. This means the letter 'a' will be treated by the computer as the value 97.

(Now do not get confused as to how 97 is a binary stream. 97 is converted to it's binary form as 0110 0001)

Our texts do not contain just letters. They also include numbers and special characters. So these also are included in the ASCII code list.

Apart from ASCII, there is also the "extended ASCII" - which handles other language characters like those from Greek / Latin etc, apart from all characters supported by the standard ASCII set!

And I am not repeating the ASCII table. Others have already mentioned sources.

Answer 4

The numerical value, or order, of an ASCII character. There are 128 standard ASCII characters, numbered from 0 to 127. Extended ASCII adds another 128 values and goes to 255. The numbers are typically represented in decimal or in hexadecimal

Answer 5

All the data in computers feeds in ascii value format i.e. 0 1

Answer 6

ASCII stands for American Standard Code for Information Interchange.

Computers dont understand simple English which we speak or write. For this reason the data which we provide to the computer has to converted in the form of bits and bytes. Bits and bytes consists of 0 and 1.(8bits=1 byte) and Hexa-decimal nos.
The codes interchanges the value which you have typed or entered in ASCII values and passes to the computer. The computer in return passes bits and bytes value to us which is again interchanged to plain English by ascii code and returned back to us.

Answer 7

Here is a complete explanation of the ASCII code, including a table of the codes and the values.

Answer 8

ASCII-American code for Information Interchange.

1)acode that represents letters, numerals, punctuation marks and control signals as seven bit groups. It is used as a standard code by the transmission of data. The values range from hex value 00 to hex value 7F.

2)American Standard Code for Information Interchange) -- This is the de facto world-wide standard for the code numbers used by computers to represent all the upper and lower-case Latin letters, numbers, punctuation, etc. There are 128 standard ASCII codes each of which can be represented by a 7 digit binary number: 0000000 through 1111111.

3) Pronounced AS-key

hope i too participate to clear ur doubt!!

Answer 9

ASCII Value is a unique 8 bit number assigned to each characters. For e.g A - 65 , B - 66 ... 0 - 48 , 1 - 49

You can find more @ http://www.neurophys.wisc.edu/comp/docs/ascii.html

Answer 10

all letters and symbols have an ASCII number 0-255

Answer 11

the value of ascii code is to generate other characters into 1s and 0s... that is how...

example, it is long write 00010000 instead of using character example A10B...
