Vertical Redundancy Check (VRC) is a simple error detection technique used in by the TCP/IP protocol suite to identify errors caused by the flipping of a single bit during network transmission. It is also known as parity check. Vertical Redundancy Check (VRC) adds a one bit to the data that to be sent. This bit …
Error detection and correction are techniques used in data communication to ensure the integrity and reliability of transmitted data. Suppose A is sending some data to B via some transmission media. This data may be corrupted during transmission. This simple means that a 0 bit may change to 1 or a 1 bit may change …

Selective Repeat Protocol is a sliding window protocol used in the data link layer for efficient data transmission in computer networks. It is used to transmit data over noisy channels. Unlike it’s counterparts, Stop and Wait ARQ and Go-Back-N ARQ, Selective Repeat ARQ Protocol allows: Basically, if a frame is lost or damaged, the receiver …
Go-Back-N (GBN) ARQ Protocol allows the sender to send multiple frames before receiving individual acknowledgments. It is a flow control protocol used in the data link layer to achieve reliable and efficient data transmission between a sender and a receiver over a noisy channel. Sender Window Size and Sequence Numbers Go-Back-N ARQ is a sliding …
A Sliding Window Protocol is a flow control mechanism used in TCP/IP protocol to efficiently transmit data between a sender and a receiver. It allows the sender to send multiple data frames at the same time. This maximizes the efficiency while ensuring reliable delivery of frames. Unlike the Stop-and-Wait Protocol, which transmits a single frame …
Stop-and-Wait ARQ(Automatic Repeat Request) is one of the fundamental protocols used for achieving reliable data transfer. It is a flow control protocol used by the data link layer to regulate the transmission of data between a sender and a receiver. The primary purpose of the Stop-and-Wait ARQ Protocol is to ensure that each data packet …
Stop and Wait protocol is a data link layer protocol for transmission of data over noiseless channels. It is a flow control protocol used in noiseless channels. Features: Working: Sender Side: The sender sends only 1 data packet at a time. The sender would wait for acknowledgement of the packet sent. It would send the …
Flow control is a speed matching mechanism used to regulate the flow of data between devices. It ensures smooth and efficient communication. It is a responsibility of the data link layer of the TCP/IP protocol. We live in a information based world where data is constantly exchanged between various devices. This makes ensuring efficient and …
