When it comes to data transmission, parity is the name of the game. The process ensures that the number of bits with the value one, or ones, equals the total number of bits. It can be used in both hardware and software. In hardware, the parity bit is appended to the original data bits to create an even or odd bit number, the number of bits with one value. For example, if there are three bits with value one, it would be represented as a binary string (0 1 1). If only two bits with value one, it would be described as (1 0 0). In software, a parity check is performed on a character string using modulo-two addition (XOR) and bitwise AND operations. If an odd number of characters have been received, the parity check fails; otherwise, it succeeds. Sending data from one place to another is much like sending a package through the mail. First, you must decide whether to send it by plane or train. Then, you need to put all the information into an envelope with lots of stamps so it can get there safely. Once it reaches its destination, someone has to check whether or not all of the parts are accounted for and ensure they are in good shape. If they miss anything important, like a stamp, they'll re-send it until they get everything right. Once everything is verified as accurate (and complete), your package will be delivered! The only thing more annoying than a modem is a memory malfunction. If you're using parity checking to check the integrity of your data, you're probably not having fun. If you're not having fun, someone needs to fix it. Luckily for you, It's the future of memory checking. It can be done anywhere and doesn't require complex hardware or software installations. You plug it in and go!
