The protocol commonly used for remote login is SSH (Secure Shell). SSH is a cryptographic network protocol that allows secure communication and data transfer over an unsecured network. It provides a secure alternative to traditional remote login methods such as Telnet by encrypting data transmitted between the client and server, preventing eavesdropping and tampering. SSH … Read more
In CCNA (Cisco Certified Network Associate) certification and networking terminology, the routing table refers to a critical component within a router’s operating system that stores information about available routes to different network destinations. It is maintained dynamically by routing protocols or configured manually by network administrators. The routing table is fundamental to the router’s decision-making … Read more
The routing table method refers to the process by which routers and layer 3 switches construct and maintain routing tables to facilitate packet forwarding across interconnected networks. This method involves dynamically learning and updating routing information using routing protocols such as RIP, OSPF, EIGRP, or BGP. Routers exchange routing updates with neighboring routers to build … Read more
Mirroring, technology, typically refers to the process of replicating or duplicating the display of one device onto another. For example, screen mirroring allows you to display the screen of a smartphone, tablet, or computer onto a larger screen like a TV or projector. In network or server contexts, mirroring involves duplicating network traffic from one … Read more
Port forwarding and VPN (Virtual Private Network) serve different purposes in networking but can sometimes complement each other depending on the specific use case. Port forwarding involves redirecting incoming network traffic from one port on a router or firewall to another port on a different device or server within a private network. It is commonly … Read more
STP (Spanning Tree Protocol) in routing and switching is a network protocol used to prevent loops in Ethernet networks where multiple paths between switches could cause broadcast storms and network instability. STP operates by dynamically selecting a single “root bridge” among interconnected switches and then disabling redundant paths to ensure a loop-free topology. It accomplishes … Read more
Port forwarding is used to redirect incoming network traffic from one port on a router or firewall to another port on a different device or server within a private network. It enables external users or devices to access specific services or applications hosted on devices behind the router or firewall. Common applications include hosting websites, … Read more
VLAN tagging offers several benefits in network management and operation. It allows network administrators to logically segment a physical network into multiple virtual LANs (VLANs), each representing distinct broadcast domains. By assigning VLAN tags to Ethernet frames, switches can identify and forward traffic based on VLAN membership, regardless of the physical port the traffic enters. … Read more
The functions of MAC (Media Access Control) encompass several key roles in computer networking and communication protocols. Firstly, MAC addresses uniquely identify devices within a network, serving as their physical address. This allows devices to communicate with each other over Ethernet or Wi-Fi networks, ensuring data packets are correctly routed to their intended destinations based … Read more
VLAN tagging is essential for segmenting and organizing network traffic within a single physical network infrastructure. It allows network administrators to logically group devices into separate broadcast domains, or VLANs, regardless of their physical location on the network. By assigning VLAN tags to network frames, switches can direct traffic more efficiently, improving network performance and … Read more
