Question

Which statement is true about parity in RAM?

The first bit must be a 1
The last bit must be a 1
There needs to be an even number of 1 bits
There needs to be an odd number of 1 bits

Answer 1

There needs to be an odd number of 1 bits

Step-by-step explanation:

In memory, parity checking method is used to test the memory. There are two parity conditions. Either the parity is even or the parity is odd.

Odd parity means, number of 1's in eight bits of data. If the number 1's are odd it means parity is odd. In case of the memory testing result the parity should be odd.

So, In case of Parity of RAM, the parity should be odd, if the data is stored in the RAM.
