Mesh topology is a network configuration where every device in the network is directly connected to every other device, creating a fully interconnected network. In a mesh network, each device is capable of sending, receiving, and relaying data to other devices in the network. This type of topology provides redundancy, fault tolerance, and multiple communication…

IP addressing, or Internet Protocol addressing, is a system used to assign unique numerical identifiers to devices connected to an IP-based network. IP addresses enable devices to communicate with each other over a network, whether it’s a local area network (LAN) or the global Internet. In the context of IP addressing, there are two primary…

MAC addressing (Media Access Control addressing) is a method used to uniquely identify network devices at the data link layer of the networking protocol stack. MAC addresses are assigned to network interface cards (NICs) and are used for communication within a local network.MAC addressing plays a crucial role in local network communication, as it enables…

Domain names provide a human-readable and memorable way to access resources on the Internet. They play a crucial role in navigating the web and accessing websites, email servers, FTP servers, and other network resources. The hierarchical structure of domain names, along with the DNS infrastructure, ensures efficient and reliable resolution of domain names to their…

Internet Protocol (IP) is a fundamental protocol of the Internet that provides a set of rules for sending and receiving data packets between devices connected to a network. It is a connectionless protocol, meaning that it does not establish a dedicated connection before transmitting data. IP operates at the network layer of the TCP/IP protocol…
-
Transmission Control Protocol (TCP) is a core protocol of the Internet protocol suite that provides reliable, connection-oriented communication between devices over IP networks. It ensures that data packets are delivered in order, without errors, duplication, or loss. TCP is a key component of many network applications and is widely used for transmitting data across the…

The User Datagram Protocol (UDP) is a connectionless transport layer protocol used in computer networks. It provides a simple, minimalistic, and lightweight method of delivering data between devices on a network. UDP is part of the Internet Protocol Suite and works alongside the Internet Protocol (IP). Unlike the Transmission Control Protocol (TCP), UDP does not…

The Internet Control Message Protocol (ICMP) is an essential network-layer protocol within the Internet Protocol Suite. It plays a crucial role in facilitating communication and exchanging error messages between network devices. ICMP is primarily designed to provide diagnostic and troubleshooting capabilities, allowing network administrators to monitor and manage network connectivity. ICMP operates at the network…

In computer networking, an access point (AP) is a device that acts as a central hub for connecting wireless devices to a wired network. It serves as a bridge between wireless devices, such as laptops, smartphones, and tablets, and the existing wired infrastructure, typically a local area network (LAN) or the internet. The access point…

The Address Resolution Protocol (ARP) is a fundamental protocol used in computer networks to map an IP (Internet Protocol) address to a physical (MAC) address. It operates at the Data Link Layer (Layer 2) of the OSI (Open Systems Interconnection) model and plays a crucial role in facilitating communication between devices within a local network.The…
