In most of the systems, data collection is one of the major tasks to be carried out. The way of data collection can be automatic or manual. Adversity is the main cause that in many systems, manual intervention is not possible. So, opting for automated way isn't such bad idea. Depending upon the way of communication, wired or wireless, data can be collected through either wired or wireless networks...
