When parity memory detects errors what happens?

PARITY
What is the difference between ECC and parity memory?
ecc momory can detect and repair errors
A problem with parity error indicates a problem with?
Parity error indicates bad memory. Parity checks compare the memory read with what was writen.
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 the advantage of simple parity check?
Simple parity check is easy to implement and helps to detect single-bit errors in data transmission. It is a simple and fast error detection technique that adds minimal overhead to the data being transmitted. However, it is limited in its ability to detect multiple bit errors or correct any errors detected.
What happens when parity memory detects an error?
A parity error always causes the system to halt.
What component would cause a parity error?
Parity errors can occur in any device that stores data. It is usually not noticed unless the system has provisions (BIOS and software) to detect those errors. ECC memory and hard drives using certain configurations (such as RAID) are typical.
What can occur in older SIMMs and only happens when a module's parity information doesn't match information in memory?
Parity Error
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.
What types of errors will simple parity not detect?
Simple parity can not correct multiple errors. If more than one error exists at a time, then simple parity can not calculate the missing data.
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.
