Network

Fiber optics are used for various purposes, primarily in telecommunications and networking to transmit data signals over long distances at high speeds. They are also employed in medical imaging, industrial sensing, and automotive applications where reliable and high-bandwidth communication is essential. The purpose of using fiber optics lies in its ability to provide high-speed, reliable, … Read more

The three types of NFS (Network File System) primarily refer to different versions or protocols used for file sharing over a network: NFSv2 (Network File System version 2): This was an early version of NFS developed by Sun Microsystems. NFSv2 used UDP (User Datagram Protocol) for data transmission and lacked features such as strong security … Read more

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
