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 01
With even parity, the bit must be a 1
0 _ 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 1
With even parity, the bit must be a 0
0 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 1
With 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 1
With even parity, the bit must be a 1
0 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 does longitudinal parity works?
Longitudinal parity, sometime it is also called longitudinal redundancy check or horizontal parity, tries to solve the main weakness of simple parity.The first step of this parity scheme involves grouping individual character together in a block, as fig given below 1.1fig.Each character (also called a row) in the block has its own parity bit. In addition, after a certain number of character are sent, a row of parity bits, or a block character check, is also sent. Each parity bit in this last row is a parity check for all the bits in the Colum above it. If one bit is altered in the Row 1, the parity bit at the end of row 1 signals an error. If two bits in Row 1 are flipped, the Row 1 parity check will not signal error, but two Colum parity checks will signal errors. By this way how longitudinal parity is able to detect more errors than simple parity.
Would you expect that the inclusion of a parity bit with each character would change the probability of receiving a correct message?
The inclusion of a parity bit extends the message length. There are more bits that can be in error since the parity bit is now included. The parity bit may be in error when there are no errors in the corresponding data bits. Therefore, the inclusion of a parity bit with each character would change the probability of receiving a correct message.
Given the character 0110101 with bit will be added to support even parity?
0.
What is parity interrupt?
There is no parity interrupt on the 8085 or 8086/8088. If you mean a memory parity interrupt, that is a function of system design, not a function of the particular microprocessor involved. Generally, a memory parity error is fatal, so one would typically place it on a non-maskable interrupt, such as TRAP on the 8085, or INT 2 (NMI) on the 8086/8088. This assumes, of course, that the memory parity error does not just crash the processor.
Types of parity bits?
There are two types of parity bits.they are even and odd parity.
When parity detects an error what happens?
A parity error always causes the system to hault. On the screen, you see the error message parity error 1 (parity error on the motherboard) or parity error 2 (parity error on an expansion card)

what is meant by the terms odd parity even parity marking parity?
Odd parity and even parity are error detection schemes used in digital communication and computer memory. In odd parity, the number of bits set to '1' in a binary sequence is always odd, while in even parity, it is always even. Marking parity refers to a specific implementation of even parity where a binary '1' is added as a parity bit to ensure that the total number of '1's is even. These methods help identify errors in data transmission or storage by providing a simple means of checking integrity.
How are parity errors in memory detected?
Parity errors in memory are detected using a simple error-checking mechanism that involves an additional bit known as the parity bit. This bit is added to a group of bits (like a byte) to ensure that the total number of 1s is either even (even parity) or odd (odd parity). When data is read from memory, the system recalculates the parity and compares it to the stored parity bit; if there's a mismatch, a parity error is flagged, indicating that the data may be corrupted.
