What Is Error Control (EC)?

With proper Error Control (EC), there's no need to worry. Your message will be sent and received just like you thought it would. It can offer you calmness of mind because it works differently. Error control is the technique used to ensure that received data is identical to transmitted data. If proper error control is in place, sent and received information is guaranteed to be exact, as in many cases, communication channels can be highly unreliable. It is common for data to be corrupted or lost during transmission, so it is essential to detect and handle these cases. If data is sent and not received, or received but not used, the operation results are not the same as the initially sent data, causing an error. There are several ways to handle mistakes in programming languages, from simple try/catch blocks to more advanced options like enumerable types with a selective catch. Most modern programming languages will give you options to handle errors, but you may want to consider implementing your system. Error control techniques are primarily implemented in the Open Systems Interconnection (OSI) model; however, some network protocols also provide acknowledgment and retransmission functions at the data link layer. Error control is done in two ways: at the physical layer to reduce errors during transmission and at the data link layer to provide reliable data delivery. The physical layer, which includes the transmission media, is the most basic level of error control. It consists of the cable's electrical properties and the electromagnetic properties of the wireless signals. Protocols provide error control at the data link layer by acknowledging and retransmitting data and offering other functions. For example, the IEEE 802. 11 wireless standard includes authentication, security, and connection establishment functions. Error control is the way to ensure that all bits of data transmitted and received by two computers are identical. With proper error control in place, you can rest assured that every word, sentence, and thought your beloved would receive is precisely how you want it to be. There's no need for guessing anymore!
