Q. Explain Error Detection and Correction Codes?
Before we wind up data representation in reference of today's computers one should determine about code that helps in correction and recognition of errors. Computer is an electronic media hence there is a probability of errors at the time of data transmission. These kinds of errors can result from disturbances in transmission media or external environment. But what is an error in binary bit? An error bit alters from 0 to 1 or 1 to 0. One of simplest error detection codes is known as parity bit.
Define race condition. When several process access and manipulate similar data concurrently, then the outcome of the implementation depends on particular order in which the ac

For the 8-bit bidirectional register in Figure 3, verify the status of the register after every clock pulse for the LEFT RIGHT /control waveform given. A HIGH on this input permits
What happens if only one of the commands SET SCREEN and LEAVE SCREEN is used without using the other? If we use SET SCREEN without LEAVE SCREEN, the program ends processing for
What is Error detection code? It is a binary code that notice digital errors during transmission. The detected errors cannot be correct but the presence is shown.
