If two bits of a byte are in error when the byte is read from ECC memory can ECC detect the error Can it fix the error?

ECC can detect the error but cannot correct it.

If two bits of a byte are in error?
If two bits of a byte are in error when the byte is read from ECC memory, ECC can detect the error.
What is byte addressable memory?
a byte is abasic storage unit in memory. when application program instructions and data are transferd to memory from storage devices. byte addressable memory refers to memory address that is accessed one byte (8 bits) at a time as opposed to 2 byte(16 bits), 4 byte(32 bits) or 8 byte(64 bits) addressable memory.
How do you define a byte?
A byte is a unit of memory consisting of eight binary digits or bits
What is parity generation?
Add up all the bits in a "word" - usually in 7 bits of an 8 but byte, and use the top bit in the byte to store the result. If there is an even number of bits set, the "parity bit" is 0, and if it is odd, the "parity bit" should be 1. Electronic circuits can easily be made that generates this on say a COM port, that transmits one bit at a time and makes it possible to detect errors in the communication. It is also used in RAM memory - also to identify faulty memory chips. On disks they use more than 1 bit, and will here call it "ECC" - "Error Correction Circuitry". This is based on 3 bits that enables reconstructing the byte, not just detect an error. Dense storage and fast transmission is always a trade-off with the correct stored data or data transmitted. Where the errors can be corrected without reducing capacity this is used.
What is a group of 8 bits usually called?
8 bits grouped together is called a byte. A byte is a unit of digital information in computing and telecommunications that typically consists of eight bits. Bytes are often used to represent a character such as a letter, number, or symbol in a computer's memory. The size of a byte can vary depending on the computer architecture, but it is typically 8 bits on most modern systems.
In memory what is a byte?
A byte is a group of 8 bits of computer data. A bit represents either a 0 or a 1.
How many bits are stored by a 256 x 4 memory chip can this chip be specified as 128 byte memory?
256x4=1024 bits are stored.128x8=1024 ,yes this chip can be specified as 128 byte
What is a byte and how many bits does it contain?
A byte is the basic unit of information in a computer. It is usually the smallest addressable object in memory. The size of a byte is a function of the design of the computer, but nearly universally, it has come to mean 8 bits. (Octet is a more precise definition of 8 bits of memory, in case there is any dichotomy.)
How bits are in a byte?
Eight bits are in one byte
What is the address of the last byte of RAM in the Pep8 memory?
2 bytes or 16 bits
What is a byte equal to?
Basically, these are the memory units used to represent the memory of the computing devices. Bit Byte (Contains 8 bits) Kilo-byte (Contains 1024 bytes) Mega-Byte (Contains 1024 kilo-bytes) Giga-Byte (Contains 1024 Mega-bytes) Tera-Byte (Contains 1024 Giga-bytes) and so on....
How many bits are there in a byte?
Generally speaking, eight bits to a byte. There is no actual standard that defines how many bits are in a byte, but it has become something of a de facto standard.
