The NIC portal refers to the online platform provided by the National Informatics Centre (NIC) that offers various digital services, information, and resources to government departments, citizens, and businesses in India. The work of NIC includes developing and managing IT infrastructure, providing e-governance solutions, and offering consultancy services to government organizations. NIC supports the implementation … Read more
The BGP (Border Gateway Protocol) protocol algorithm is based on a path vector routing algorithm. Unlike traditional link-state or distance vector algorithms used in interior gateway protocols, BGP operates by exchanging routing information containing network reachability information along with path attributes. This allows BGP to make routing decisions based on policies, path attributes, and AS … Read more
The difference between FTP (File Transfer Protocol) and SMB (Server Message Block) is that FTP is primarily used for transferring files between a client and a server over a network, while SMB is used for sharing files, printers, and other resources over a local network. An advantage of SMB over FTP is that SMB supports … Read more
MPLS (Multiprotocol Label Switching) architecture is a method used in telecommunications networks to efficiently direct data packets through a network. It operates between Layer 2 (data link layer) and Layer 3 (network layer) of the OSI model, enabling faster packet forwarding by using labels to designate paths instead of traditional IP routing tables. MPLS architecture … Read more
The purpose of SMB (Server Message Block) is to enable shared access to files, printers, and other resources over a network. It allows computers to communicate with each other and share resources in a seamless manner, making it easier for users to access and manage network resources. The benefits of SMB include efficient file and … Read more
VPLS (Virtual Private LAN Service) and MPLS (Multiprotocol Label Switching) are both technologies used in networking, but they serve different purposes and operate at different layers of the OSI model. VPLS is a Layer 2 service that extends Ethernet LANs over a wide area network (WAN) using MPLS as the transport mechanism. It allows geographically … Read more
NFS (Network File System) is a distributed file system protocol that allows clients to access files over a network as if they were local files. One advantage of NFS is its platform independence, allowing clients running different operating systems to access shared files. However, NFS performance can be affected by network latency and reliability issues, … Read more
The intrusion detection system (IDS) is a security technology designed to monitor network and system activities for malicious actions or policy violations. It analyzes traffic patterns, identifies suspicious activities, and generates alerts for administrators to investigate potential security incidents. Intrusion detection system refers to a hardware or software application that automatically monitors events occurring in … Read more
EIGRP (Enhanced Interior Gateway Routing Protocol) is used primarily for routing within enterprise networks. It is designed to provide fast convergence, low overhead, and support for a variety of network topologies. EIGRP is particularly advantageous in large-scale networks where rapid and efficient routing updates are crucial for maintaining network performance and reliability. EIGRP and OSPF … Read more
A virtual private network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the internet. This ensures privacy and security for data transmitted between the user’s device and the VPN server. Virtual private network refers to a service that allows users to access the internet securely … Read more
