In this error detection method, a block of bits is organized in a table with rows and columns. Then the parity bit for each column is calculated and a new row of eight bits, which are the parity bits for the whole block, is created. After that the new calculated parity bits are attached to(…)

The simplest and oldest error detection method. A binary digit called parity is used to indicate whether the number of bits with “1” in a given set of bits is even or odd. The parity bit is then appended to original data. Usually used to detect transmission error . Sender adds the parity bit to(…)

In a bit-oriented protocol, the data to send is a series of bits. In order to distinguish frames, most protocols use a bit pattern of 8-bit length (01111110) as flag at the beginning and end of each frame. Here also cause the problem of appearance of flag in the data part to deal with this(…)

A named pipe is really just a special kind of file (a FIFO file) on the local hard drive. Unlike a regular file, a FIFO file does not contain any user information. Instead, it allows two or more processes to communicate with each other by reading/writing to/from this file. Creating FIFO File You can create(…)
