A network-based file system is a storage system that enables files and directories to be accessed over a network by multiple clients. It allows users and applications to store, retrieve, and manage data as if it were stored locally, regardless of the physical location of the storage devices. Network-based file systems provide a centralized approach … Read more
SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols used to secure communication over a computer network, typically between a client (like a web browser) and a server (like a web server). Here’s how they differ: SSL was the predecessor to TLS, initially developed by Netscape in the early 1990s. It provided … Read more
The Session Initiation Protocol (SIP) is a signaling protocol widely used for initiating, maintaining, and terminating communication sessions over IP networks. It is commonly used for voice and video calls, instant messaging, multimedia conferences, and other real-time communication applications. SIP operates independently of the underlying transport layer protocol and is designed to be flexible and … Read more
A Transport Layer Security (TLS) session refers to a secure communication session established between a client and a server using the TLS protocol. It encompasses the entire process from the initial handshake, where the client and server negotiate security parameters, to the secure exchange of data using encryption algorithms agreed upon during the handshake. A … Read more
The purpose of IGMP (Internet Group Management Protocol) is to manage and control IP multicast group membership within a network. It allows hosts to inform multicast routers about their interest in receiving multicast traffic for specific multicast groups. IGMP ensures efficient delivery of multicast packets by enabling routers to forward multicast traffic only to those … Read more
Secure Shell (SSH) is a cryptographic network protocol that provides secure communication over an unsecured network. It is commonly used for remote login and command-line execution, allowing users to securely access and manage systems and devices remotely. SSH encrypts data exchanged between the client and server, preventing eavesdropping and tampering by malicious parties during transmission. … Read more
CDP (Cisco Discovery Protocol) and LLDP (Link Layer Discovery Protocol) are protocols used in networking for device discovery and network topology mapping. CDP and LLDP serve the purpose of enabling devices to discover and learn information about neighboring devices connected directly to them in a network. They facilitate automatic discovery of network neighbors, including device … Read more
Remote Desktop Protocol (RDP) primarily uses TCP (Transmission Control Protocol) for its transport layer protocol, specifically on port 3389. TCP ensures reliable and ordered delivery of data between the RDP client (local machine) and RDP server (remote machine), crucial for maintaining the integrity and responsiveness of remote desktop sessions. UDP (User Datagram Protocol) is not … Read more
LLDP (Link Layer Discovery Protocol) offers several benefits in network management and configuration. It provides automatic discovery of network devices and their capabilities, enabling network administrators to quickly identify and verify the physical connections and configurations within the network. This reduces manual configuration efforts and enhances network visibility, making it easier to manage and troubleshoot … Read more
Remote Desktop Protocol (RDP) and Virtual Private Network (VPN) serve distinct purposes in network communication and remote access: RDP is a protocol that allows a user to remotely access and control a computer or server’s desktop interface over a network. It enables interactive sessions where a user can view and interact with the desktop environment … Read more
