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.
Data Stream and Instruction Stream The term 'stream' refers to an order or flow of either data operated or instructions on by the computer. In the complete chain of instructi
Parallelism Conditions As discussed earlier, parallel computing needs that the segments to be implemented in parallel must be free of each other. Thus, before implementing para

Is it possible to pass data to and from include programs explicitly? No. If it is needed to pass data to and from modules it is needed to use subroutines or function modules.
Digital versatile disk (DVD) This is an optical system for storing data. It's similar to CD though typically can hold 4.7 Gbyte of data compared to only 700 MB of data on a CD.
