Flow Control vs Error Control

Difference Between Flow Control and Error Control


Flow control and Error control are the control mechanism at data link layer and transport layer. Whenever the sends the data to the receiver these two mechanisms helps in proper delivering of the reliable data to the receiver. The main difference between the flow control and error control is that the flow control observes the proper flow of the data from sender to receiver, on the other hand, the error control observes that the data delivered to the receiver is error free and reliable.

Basis for ComparisonFlow ControlError Control
BasicFlow control is meant for the proper transmission of the data from sender to the receiver.Error control is meant for delivering the error-free data to the receiver.
ApproachFeedback-based flow control and rate-based flow control are the approaches to achieve the proper flow control.Parity checking, Cyclic Redundancy Code (CRC) and checksum are the approaches to detect the error in data. Hamming code, Binary Convolution codes, Reed-Solomon code, Low-Density Parity Check codes are the approaches to correct the error in data.
Impactavoid overrunning of receivers buffer and prevents the data loss.

Conclusion:

Both the control mechanism i.e. Flow control and Error control are the unavoidable mechanism for delivering a complete and reliable data.

Process Vs Thread

The Process and Thread are the essentially correlated. The process is an execution of a program whereas thread is an execution of a program driven by the environment of a process. Another major point which differentiates process and thread is that processes are isolated with each other whereas threads share memory or resources with each other. Key Differences Between Process and Thread : All threads of a program are logically contained within a process. A process is heavy weighted, but a thread is light weighted. A program is an isolated execution unit whereas thread is not isolated and shares memory. A thread cannot have an individual existence; it is attached to a process. On the other hand, a process can exist individually. Each thread has its own stack, so if a thread dies its stack is reclaimed. In contrast, if a process dies, all threads die including the process. Conclusion: Processes are used to achieve execution of programs in concurrent and sequential manner.

Reasoning Vs Inference

Inference: Inference is a general term representing the derivation of new knowledge from existing knowledge and axioms (i.e., rules of derivation) within a single step, and can be one of many kinds, such as, induction, deduction and abduction. For example, "modus tollens" is a rule of inference. Thus, one inference is the derivation of new knowledge using a single step using modus tollens. Inference is about taking in data and trying to draw a conclusion based on the limited information you have in a situation where not all the data is given. Reasoning: Reasoning is in context of a goal (e.g., decide whether a propositional formula is satisfiable or not)  and is carried out via a search process involving multiple inferences. Choices during such search have to be made such as which axiom to "fire" along with which knowledge in order to derive new knowledge. Resolution is a particular kind of reasoning involving the "resolution rule". Reasoning is

Frame vs Packet

Image
Difference Between Frame and Packet     The crucial difference between frame and packet is that frame is the serial collection of bits, and it encapsulates packets whereas packets are the fragmented form of data and it encapsulates segment. Data link layer performs framing process. On the other hand, Network layer performs fragmentation of the data and create smaller chunks known as packets. Another major difference is that a frame includes device’s MAC address while a packet includes device’s IP address. Basis for comparison Frame Packet Basic Frame is the data link layer protocol data unit. Packet is the network layer protocol data unit. Associated OSI layer Data link layer Network layer Includes Source and destination MAC address. Source and destination IP address. Correlation Segment is encapsulated within a packet. Packet is encapsulated within a frame. Conclusion: Frames and Packets function as protocol data units utilized on the
