PAN (Personal Area Network) is a close-knit network that allows your devices to communicate. Consider it your digital campfire, where devices like smartphones, computers, and wearables congregate for smooth data exchange. PANs utilize Bluetooth or Wi-Fi to provide a convenient, immediate link for sharing files, information, or even music without the hassle of a large ...
At the heart of modern connectedness, a computer network is a web of interconnected devices communicating and exchanging resources in real time. It is a virtual highway connecting computers, smartphones, and other devices to enable collaboration, information exchange, and access to shared data. Consider it a digital neighborhood where information flows like a conversation, whether ...
The simplest protocol is a data link layer protocol used for noiseless channels. The simplest protocol is also known as the Elementary Data Link Protocol. As the simplest protocol is used in noiseless channels, it has no error control and no flow control. In the simplest protocol, we assume that the receiver is always ready to ...
The selective repeat ARQ is one of the Sliding Window Protocol strategies that is used where reliable in-order delivery of the data packets is required. The selective repeat ARQ is used for noisy channels or links and it manages the flow and error control between the sender and the receiver. In the selective repeat ARQ, we only resend the ...
The Link State Routing Algorithm is an interior protocol used by every router to share information or knowledge about the rest of the routers on the network. The link state routing algorithm is distributed by which every router computes its routing table. With the knowledge of the network topology, a router can make its routing table. The ...

A device uses the IP address to communicate with the other devices present on the network. The two of the most commonly used IP addresses are namely IPv4 (Internet Protocol version 4) and IPv6 (Internet ...
The stop and wait ARQ is one of the Sliding Window Protocol strategies that is used where reliable ordered delivery of the data frames is required. The stop and wait ARQ is used for noisy channels or links and it manages the flow and error control between the sender and the receiver. The stop and ...
