Network Topology is the physical and logical arrangement of the nodes and links in a Computer Network. Nodes are the compute devices that connect to the network and links are the medium that connect the nodes. The network topology depicts that structure of the network along with the nodes and links. Network Topology application of…

Graph Theory
Graph Theory is a branch of Discrete Mathematics and is the study of graphs that are mathematical structures which depicts model of vertices (nodes) and edges (links) and the relationship between them. Graph theory is used in Computer Science for modeling structures of nodes and links with the relationship between them. The following is a…
Carrier Sense Multiple Access
CSMA (Carrier Sense Multiple Access) technology is used in LAN devices to prevent collision. Collision happens when devices connected in a network of collision domain transmits at the same time which will cause interruption of data flow between devices. Carrier Sense enables the network devices to listen for traffic and if the channel is free, transmission…
Switching
A switch in a Local Area Network (LAN) is a hardware device that connects multiple devices through a process known as Switching which happens at the Data Link Layer (Layer 2) of the OSI layer. Data Link layer is where a system starts placing data in the transmission medium (wired or wireless) by adding a…
Collision Domain
A LAN is network segment (wired or wireless) connecting multiple devices which becomes a network domain. If two devices are transmitting data at the same time in a network domain, they will collide and cause transmission failure due to the collusion of data. This network segment where all devices connecting to it and when transmitting…
Computer Network
A Computer Network is a connection of multiple devices which can be wired or wireless that provides communication between various devices that is connected to the network. The network can within an organization or home or across a geography. “Computer” denotes here any Compute System that has a CPU, ALU, Memory and Storage. Thus, a…
Local Area Network (LAN)
A Local Area Network (LAN) is a network that connects multiple devices and users within a single building or a small campus or a home. LAN provides connectivity between devices and users, so that they can communicate between each other. LAN compromises devices like routers, switches, desktops all connected to a network which can b…
Link-Local Multicast Name Resolution (LLMNR)
Link-Local Multicast Name Resolution (LLMNR) is a Network Protocol that is used for Name resolution based on DNS packet format operating in Layer 2 (local link) specified in RFC 4795. It is a fall-back mechanism when DNS fails. The system which needs to resolve a hostname will send out a multicast query using LLMNR and the…
Simple Network Management Protocol (SNMP)
SNMP is a protocol that is used to manage and monitor devices in IP based networks. It is used for Network Management and Network Monitoring. It collects information about the devices in a hierarchical structured way using Management Information Base (MIB). SNMP consists of the three following components: Managed Devices are the devices like server,…
Network Basic Input/Output System (NetBIOS)
NetBIOS is Network Basic Input Output System which is an API used for communication between systems over LAN (Local Area Network) like Ethernet and Token Ring. It was initially developed for IBM’s machines to communicate on LAN and later on was mostly used in Windows environment for Server Message Block (SMB) for file sharing, printing…
