Flow Control vs. Error Control

Controlling the data that flows during a session of online networking becomes necessary at various levels because most of the data stay sensitive and significant on different levels. Different ways of finishing all the processes exist and finding out the real issue. Flow control gets defined as the proper management of the flow of data between two computers, devices or nodes within a network for the purpose of handling the pacing efficiency. On the other hand, Error control gets defined as the management of the data flow for the purpose of detecting and solving the problems that occur when the information moves within devices.

Key Differences

Flow control gets defined as the proper management of the flow of data between two computers, devices or nodes within a network for handling the pacing efficiency. On the other hand, Error control gets defined as the management of the data flow for detecting and solving the problems that occur when the information moves within devices.
When the flow control runs successfully the data moves within the system in proper amounts without any distractions and blockage. On the other hand, when the error control runs successfully the information does not contain any problem and reaches the user just like it got sent initially.
Some of the primary process use for the flow control become the feedback based flow monitoring and rate based flow control that help with the entire flow structure. On the other hand, some of the main processes used for error control include parity checking, cycling redundancy code, binary convolution codes and density based checks.
The primary purpose of flow control is to ensure that the data reaches the user in proper order and amounts that rate as normal. On the other hand, the primary purpose of error control includes the finding of some problem and then solving it to keep the process running.

What is Flow Control?

Flow control gets defined as the proper management of the flow of data between two computers, devices or nodes within a network for handling the pacing efficiency. When data more than the required flows within the system it becomes difficult to keep track of all the activities and therefore most of the times, it has to retransmit for the purpose of reading. It not only wastes time but also causes various errors within the system such as data loss. For most cases, it becomes the fast sender and the slow receiver that communicates properly so that nothing goes to waste. Such type of control becomes critical because it is feasible for a sending PC to transmit data at a quicker rate than the goal PC can get and handle it. This action can happen if the getting PCs have an overwhelming activity stack in contrast with the sending PC, or if the accepting PC has less preparing power than the sending PC. The simplest method of controlling information comes to a stop and wait for flow control where the receiver tells if they are ready to take more data from each frame and the messages get broken down into several frames. The other method becomes the sliding window where the place only opens for new information when the old one gets used. Go Back N becomes another way of performing the same task where the data gets sent back to the transmitter until it has some use.

What is Error Control?

Error control gets defined as the management of the data flow for detecting and solving the problems that occur when the information moves within devices. The primary purpose of such kind of control becomes that the information that the sender sends comes to the receiver as the same. No changes exist, and no losses occur during the transmission, and therefore it gets considered as a complicated process. Two phases of such a system exist. Error detection that becomes the identification of mistakes created by commotion or different weaknesses amid transmission from the transmitter to the recipient. And the error correction that becomes the discovery of blunders and recreation of the first blunder free information. The general thought for accomplishing error detection and adjustment is to add some access to a message, which beneficiaries can use to check the consistency of the conveyed message and to recoup information that has been resolved to be undermined. Error discovery and amendment plans can be either orderly or non-precise: In a deliberate plan, the transmitter sends the first information and connects a settled number of check bits which come from the data bits by some deterministic calculation. Two types of error control exist, the first one called the forward error control adds the information before it gets transmitted and becomes useful data. The feedback error control helps in rechecking the information once it reaches the feed. These techniques become useful only when we know what type of error exists.
