The ASCII code uses seven-bit patterns to denote 128 different characters.
Ten of the characters are decimal digits 0 to 9. The higher order bits have the same pattern for all 10 digits. Each digit is identified by the low-order four bits using the binary patters of these digits. Capital and lowercase letters are encoded in a way that makes sorting of textual information easy.

How binary is stored in a computer?
There are several codes. One of the older ones is the American Standard Code for Information Interchange (ASCII). It used a 7-bit code which permitted 128 characters. When that number was found to be inadequate the American Nation Standards Institute (ANSI) introduced an 8-bit version. Computers use ANSI code pages which are whole sets of ANSI codes. Then there are other systems like UNICODE.
Happiness is to 517768399 as sepinah is to what?
The relationship between "happiness" and "517768399" seems to suggest a transformation or code. If we consider "happiness" as a word that corresponds to a numerical representation or a code, then "sepinah" could be transformed similarly. Assuming a consistent method is used for both, "sepinah" would correspond to a specific code or number based on the same criteria, but without more context, it's impossible to determine the exact equivalent.
What is the Application of ASCII?
This is a language used in computers.this is low level language.it is also called machine level language sorry but your a bit confused machine language is the number equvilant of assembly (add jmp ret or clr) ascii is the format that came about with 8 bit teletype 1" paper tape the first one was baudout 5 bit tape which allows 32 different letters so in a language like English with 26 letters if you want to put a number in a message it must be in this format "twenty nine" a-z is 26 32- 26 is 6 so the '0 to 9' wont fit baudot code introduced one of the codes for a shift Figures to go back Letters so now you can do 0-9 and sixteen more codes "$%#()...,,," ascii used a fill 1" wide paper tape that has 8 holes for the unbelievable shift to 256 characters A..Z 0..9 leaves us 220 so hey add a..z %$&... keep the old six ACK NAK BEL dont need letters figures anymore this entire page is ascii up on your browser there's a button that says view page source you can see the ascii it has codes between <> that is called HTML telling your computer " big little red blue picturehere" next came unicode which is 16bit letters adds Greek Spanish Russian and maybe 40,000 Chinese characters (simplified)
How does a parity bit in ASCII code help in error detection?
A parity bit in ASCII code provides a simple method for error detection by adding an extra bit to a binary representation of a character, ensuring that the total number of 1s in the byte is either even (even parity) or odd (odd parity). When data is transmitted, the receiving system checks the parity of the received bits against the expected parity. If there is a mismatch, it indicates that an error has occurred during transmission, allowing for the identification of potential data corruption. However, parity bits can only detect single-bit errors and cannot identify which bit is incorrect or handle more complex errors.
What is the limitation of ASCII code?
Basic ASCII does not have enough bits to deal with languages with large character sets.
State the purpose of the parity track devices?
A parity bit, or check bit, is a bit that is added to ensure that the number of bits with the value one in a set of bits is even or odd. Parity bits are used as the simplest form of error detecting code.
An 8-bit byte10101111is to be encoded using Hamming code what is the result after encoding?
To encode the 8-bit byte 10101111 using Hamming code, we need to add parity bits to detect and correct single-bit errors. For an 8-bit data, we typically need 4 parity bits, resulting in a total of 12 bits. The encoded Hamming code will interleave the parity bits at positions that are powers of 2 (1, 2, 4, 8) and calculate their values based on the data bits. The resulting encoded sequence after inserting the parity bits will be 101110111111.
How can you write your name in ASCII code using 8 bit code and parity?

What is the difference between parity and non-parity memory?
Non-parity memory is memory without parity. Parity memory is memory with extra bits, sometimes one, sometimes more, that accompany the word. These extra parity bits are generated to a known value, typically to make the total number of bits on that word even or odd. When the word is retrieved, the parity bits are compared against what they should be. If they are different, then one or more of the bits in the original word or in the parity bits must have changed. This is an error condition that can be trapped. In a multiple parity bit system, the calculation of the bits allows not only for the detection of a changed bit, but also for the identification of which bit changed. This is known as ECC parity, or Error-Correcting-Code. Often, you can detect and correct any one bit error, and you can detect, but not correct, any two bit error. Since random bits changes are rare, those that do occur are usually one bit errors, making ECC parity valuable for high reliability systems such as servers.
What is Hamming Code Explain its importance with suitable example?
Hamming Code is a system involving multiple parity bits per word such that not only can errors be detected but certain types of errors can be corrected. The first Hamming Code was called (7,4) because it added 3 parity bits to 4 data bits, creating a 7 bit code. See link for example.
Original ASCII codes were 7 bit or 8 bit?
ASCII is a 7 bit code. There are many nonstandard extensions of ASCII to 8 or 9 bits by various computer companies. ASCII was developed to replace the obsolete 6 bit BAUDOT teletype code and was never originally intended for use on computers.
Which number identified by hamming code?
Hamming code is a method used for error detection and correction in digital data transmission. It identifies a number by adding redundant bits to the original data bits, allowing for the detection and correction of single-bit errors. The code works by positioning parity bits at specific intervals and calculating their values based on the binary data. This enables the detection of errors by checking the parity bits against the expected values.
What is difference between convolutional codes and linear block code?
In linear block codes we use individual registers seperately for message bits and for parity bits while transmitting where in case of convolutional codes we use only one register and here the left most bit is the message bit and remaining are parity bits
Consider even parity design a haming code for the ascii character 'A'?
The ASCII character A is a 65 in decimal. That means it is 0100 0001 in binary. The hamming code uses extra bits to encode parity information, so the character A would be: _ _ 0 _ 1 0 0 _ 0 0 0 1 where the _ indicates a parity bit * Position 1 checks bits 1,3,5,7,9,11:? _ 0_ 1 0 0 _ 0 0 01With even parity, the bit must be a 10 _ 0_ 1 0 0 _ 0 0 01* Position 2 checks bits 2,3,6,7,10,11:0 ? 0 _ 1 0 0 _ 0 0 0 1With even parity, the bit must be a 00 0 0 _ 1 0 0 _ 0 0 0 1* Position 4 checks bits 4,5,6,7,12:0 0 0 ? 1 0 0 _ 0 0 0 1With even parity, the bit must be a 0:0 0 0 0 1 0 0 _ 0 0 0 1* Position 8 checks bits 8,9,10,11,12:0 0 0 0 1 0 0 ? 0 0 0 1With even parity, the bit must be a 10 0 0 0 1 0 0 1 0 0 0 1 The encoded character is 0 0 0 0 1 0 0 1 0 0 0 1
How efficient would a 6-bit code be in asynchronous transmission if it had two parity bits (one for each nibble) 1 start bit and one stop bit.?
In asynchronous transmission using a 6-bit code with two parity bits (one for each nibble), one start bit, and one stop bit, the total number of bits transmitted per codeword would be 10 bits (6 data bits + 2 parity bits + 1 start bit + 1 stop bit). This results in a data efficiency of 60% (6 bits of actual data out of 10 total bits). This means that for every 10 bits transmitted, only 6 bits are useful data, making it less efficient compared to systems with fewer overhead bits.
