  • Topologies: Ring Network

    In networking, the ring topology represents a structure where nodes are connected in a closed-loop or circular arrangement. Each node is connected to exactly two neighboring nodes, forming a ring-like structure. Data travels in one or both directions around the ring until it reaches its intended destination. This topology is particularly known for its simplicity…

  • IP stack : CIDR

    Classless Inter-Domain Routing (CIDR) is a modern addressing scheme used in the Internet Protocol (IP) stack to optimize the allocation of IP addresses and improve routing efficiency. Introduced in 1993, CIDR replaced the traditional class-based addressing system (Class A, B, C, etc.) by allowing for more flexible and efficient use of IP address space. It…

  • IP Stack : Loopback

    The loopback interface is a fundamental component of the IP stack, enabling internal network communications within a device. It provides a mechanism for testing and debugging network services without requiring physical network hardware. The loopback interface is identified by the IP address 127.0.0.1 for IPv4 and ::1 for IPv6, both of which are reserved specifically…

  • IP stack : Localhost

    The IP stack, also known as the Internet Protocol Suite, is the fundamental architecture that governs how data is transmitted across networks. It consists of four layers: the Link Layer, Internet Layer, Transport Layer, and Application Layer. Within the context of IP stack communication, “localhost” refers to the standard hostname for the local computer or…

  • Topologies : Bus Network

    Bus topology is one of the simplest forms of network architecture, where all devices (nodes) are connected to a single central communication line known as the “bus” or backbone. This linear structure is often used in smaller networks due to its simplicity and cost-effectiveness. Data travels along the bus, and each node checks whether the…

  • Topologies: Mesh Network

    Mesh network topology is a robust and decentralized network design where each device (or node) is interconnected with one or more other nodes. This architecture ensures multiple paths for data transmission, promoting reliability, redundancy, and efficiency. Mesh networks are commonly used in critical systems such as wireless networks, IoT applications, and military communications due to…

  • Topologies : Star Network

    Star network topology is one of the most commonly used architectures in modern networking. In this design, all devices (nodes) are connected to a central hub or switch, which acts as the primary point for communication. This centralized structure simplifies management, improves performance, and ensures efficient data routing, making star topology ideal for both small-scale…

  • CIDR Block

    A Classless Inter-Domain Routing (CIDR) block is a method for allocating and managing IP addresses in a flexible manner, reducing wastage of IP space. In cloud environments like AWS, CIDR blocks define the range of IP addresses that can be allocated to resources within a Virtual Private Cloud (VPC) or subnet. Mastering CIDR configuration is…
