It is a collection of processes that tells the sender how much data it can send before the data destroys the receiver. The receiving device has finite speed and limited memory to save the data.Thus, the receiving device should be able to instruct the sending device to stop the transmission temporarily before the limits are arrived.There is another essential problem in the data link design to manage the cost of data communication between two source and destination hosts. If the conflict between the source and destination hosts data sending and receiving speed, it will make packets drop at the receiver ... Read More

Data Link Control is the service provided by the Data Link Layer to offer reliable data transfer over the physical channel. It takes the physical layer’s bits and finds an error.This creates an error-free communications path among network nodes over the physical medium, frames messages for communication, tests the integrity of received messages, manages access to and uses the medium, ensures the proper sequence of transmitted data.Error ControlIt contains sequencing frames and transmitting control frames for acceptance. A noisy channel can avoid scanning of bits, falling bits from a frame, introducing specific bits in the frame, frames final sinking, etc.The ... Read More

DWDM represents Dense Wavelength Division Multiplexing. It is a technology in which several optical signals (laser light) of multiple wavelengths or colors are combined into one signal and are sent over the connecting channel to a lengthy area.When the optical signal transmission distance changes into thousands of kilometers, it results in loss of few signals. It can fascinate this signal loss, optical fibre amplifiers are used in the DWDM transmission system.The DWDM technology needed this gain bandwidth to share various optical signals together efficiently. DWDM can address up to 80 channels (80 optical signals) with 100 GHz (0.8 nm) spacing.Dense ... Read More

Computer Network is an interconnection of numerous computers to share an operating system, hardware, and information through a transmission mode among them. There is no condition to the location between two computers in a network.Elements of Computer NetworkA computer network involves the following elements −Nodes (Workstations) − The multiple terminals linked to the network sharing the network resources are known as nodes.Server − It can assign a specific node as a central node at a well-known and permanent address to support the network. The node supporting the service is referred to as the server.Network Interface Unit − The interpreter, which ... Read More

First, let us understand what File Transfer Protocol (FTP) is.FTPFTP represents File transfer protocol. FTP is a standard internet protocol supported by TCP/IP used for sharing the records from one host to another. FTP needs TCP as a transport protocol to help the reliable end-to-end connections and executes two types of connections in managing data transfers.The FTP clients initiate the first connection, referred to as the control connection, to well-known port 21 (the client’s port is typically ephemeral). It is on this element that an FTP server listens for it and approaches new connections. The control connection is expressed for ... Read More
