A ZigBee module is a component that enables devices to communicate wirelessly using ZigBee protocol. It typically includes a microcontroller, ZigBee radio transceiver, and antenna, allowing devices to form a ZigBee network for data exchange over short distances. ZigBee is a wireless communication protocol designed for low-power, low-data-rate applications such as home automation, industrial control, … Read more
NFS (Network File System) is known for its role in facilitating distributed file access and sharing across heterogeneous networks. It allows users to access files and directories stored on remote servers as if they were local, regardless of the client’s operating system. NFS simplifies data sharing and collaboration within organizations by providing a seamless way … Read more
There are three main types of ZigBee networks: ZigBee Coordinator, ZigBee Router, and ZigBee End Device. The ZigBee Coordinator acts as the network controller and initiates the formation of the ZigBee network. It manages communication between devices and can also function as a bridge to other networks like Wi-Fi or Ethernet. ZigBee Routers extend the … Read more
IGMP (Internet Group Management Protocol) operates at Layer 3 (Network Layer) of the OSI model. Its primary function is to manage multicast group memberships within a network. IGMP enables hosts to inform routers about their interest in receiving multicast traffic for specific multicast groups. Routers use this information to efficiently deliver multicast packets only to … Read more
ZigBee is used for various applications primarily in the realm of wireless sensor networks and low-power, low-data-rate communications. It is commonly employed in smart home automation systems to connect and control devices such as smart lights, thermostats, door locks, and sensors. ZigBee’s mesh networking capability allows for reliable communication over extended distances and through obstacles, … Read more
EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path First) are both routing protocols used in computer networks, but they differ in their operation and deployment scenarios. EIGRP is a proprietary Cisco routing protocol designed for efficient routing within enterprise networks. It uses a hybrid routing protocol that combines the benefits of distance-vector … Read more
WPA2 (Wi-Fi Protected Access 2) and WPA3 (Wi-Fi Protected Access 3) are security protocols used to secure wireless networks, specifically Wi-Fi connections. WPA2 has been the standard for securing Wi-Fi networks for many years. It uses the AES (Advanced Encryption Standard) protocol for encryption and offers robust security features such as encryption keys and authentication … Read more
Network File Storage (NFS) refers to a distributed file system protocol that allows a client computer to access files over a network as if they were stored locally. NFS enables remote file sharing and access between computers in a networked environment, regardless of their operating systems. It operates on a client-server model, where the NFS … Read more
The purpose of the IDS (Intrusion Detection System) is to monitor network traffic for suspicious activities and potential threats, alerting administrators when it detects unusual or malicious behavior. The purpose of the IPS (Intrusion Prevention System) is to monitor network traffic for suspicious activities and take immediate action to block or prevent malicious activities from … Read more
Routing protocols can generally be categorized into three types: Distance Vector Routing Protocols: These protocols determine the best path to a destination network based on distance or hop count. Examples include Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP). Link-State Routing Protocols: These protocols build a detailed map of the network topology by … Read more
