CN Tutorial

Routing in Computer Networks Routing is the process of determining the optimal path for data to travel from a source to a destination in a network. Think of it as a GPS system for data packets, where routers act as the guiding waypoints along the route. The primary objectives of routing are to minimize latency, […]

Network addressing in CN Network addressing refers to the methodology of assigning unique identifiers to devices within a computer network to facilitate communication. These addresses enable devices to locate and exchange data with each other across the network. Network addressing is a fundamental aspect of networking and plays a crucial role in ensuring the proper

ALOHA in Computer Network The Multiple-access protocol ALOHA allows data to be exchanged over a common network channel. It works on the medium access control sublayer of the open systems interconnection (OSI) architecture. (Mac sublayer). Using this protocol, multiple data streams from different places are delivered over a multi-point transmission path. Norman Abramson and colleagues

What is IP Address? Types of IP Address An IP address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses serve two main purposes: identifying the host or network interface and providing a means for location addressing. IP addresses

Flow Control in Computer Networks Flow control in computer networks is a mechanism used to regulate the flow of data between sender and receiver to ensure efficient and reliable communication. It manages the rate at which data is transmitted to prevent data overflow, congestion, and loss. Flow control mechanisms are essential in preventing the receiver

Error Control In Computer Networks Error control in computer networks refers to the techniques and mechanisms used to detect, manage, and correct errors that occur during data transmission. It plays a critical role in ensuring the reliability and integrity of data communication across networks. Error control includes both Error Detection and Error correction strategies, which

Error Correction in Computer Networks Error correction in computer networks refers to the process of identifying and rectifying errors that occur during data transmission or storage. It aims to ensure the integrity and reliability of data by automatically detecting and correcting errors without the need for manual intervention. Error correction techniques are essential for maintaining

Error Detection in Computer Networks An error is a mistake, inaccuracy, or divergence from a set of rules. An error happens in computer networks when the message received at the receiver’s end differs from the message sent. Many factors, like as noise or crosstalk, can cause digital signals to create errors in the binary bits

Switching in Computer Networks Switching in computer networks refers to the process of directing data packets from a source device to a destination device within a network. It involves the selection of an appropriate path or route for data transmission based on the destination address contained in each packet. Switching plays a fundamental role in

Multiplexing in Computer Networks Multiplexing is a technique used to combine multiple signals or data streams into a single signal over a shared medium for transmission. This allows for the optimization of bandwidth utilization and the efficient use of network resources. Think of multiplexing as a way to pack more data into the same channel
