What is Wildcard Mask? A wildcard mask is a sequence of numbers that streamlines packet routing inside a proprietary network’s subnets. It is also referred to as an inverse mask. The main reason behind this is that unlike a subnet mask in which, binary 1, is equal to a match, and binary 0 is not…

What is Subnetting? Subnetting is the practice of dividing a network into two or smaller networks. It increases routing efficiency, which helps to enhance the security of the network and reduces the size of the broadcast domain. IP Subnetting designates high-order bits from the host as part of the network prefix. This method divides a…

What is Layer 2 switching? The term Layer 2 is adopted from the Open System Interconnect (OSI) model, which is a reference model for explaining and describing network communications. It is the process of using devices and MAC addresses on a LAN to segment a network. Switches and bridges are mostly used for Layer 2…

What is IP routing? IP Routing is a process that sends packets from a host on one network to another host on a different remote network. It helps you examine the destination IP address of a packet, determine the next-hop address, and forward it. IP routers use routing tables to determine the next-hop address to…

What is STP? STP is a link management protocol designed to support redundant links that stops switching loops in the STP network. It is a Layer 2 protocol that runs on bridges and switches, which should be enabled on the switch interfaces. IEEE standardized STP protocols as IEE 802.1D. The full form of STP is…

What is Domain? A domain is a type of computer network in which all user computers, printers accounts, and other devices registered. It is a central database located on single or multiple clusters of central computers, that is known as domain controllers. What is Collision Domain? The collision domain defines the set of devices on…

What is an Error? Transmitted data can be corrupted during communication. It is likely to be affected by external noise or other physical failures. In such a situation, the input data can’t be the same as the output data. This mismatch is known as “Error.” The data errors may result in the loss of important…
