Detailed explanation-1: -Real-time data processing is the execution of data in a short time period, providing near-instantaneous output. The processing is done as the data is inputted, so it needs a continuous stream of input data in order to provide a continuous output.
Detailed explanation-2: -near real-time. While the absolute definition is debated, the answer is quite simple: real-time is instant, whereas near real-time is delayed (whether that’s by a few milliseconds or a few hours). This can get confusing as having real-time is close to impossible when it comes to sensors and security.
Detailed explanation-3: -There are three main data processing methods-manual, mechanical and electronic.
Detailed explanation-4: -In batch processing processor only needs to busy when work is assigned to it. In real time processing processor needs to very responsive and active all the time. Jobs with similar requirements are batched together and run through the computer as a group.
