The routing table in networking serves several critical uses. It provides routers and layer 3 switches with a comprehensive list of known network destinations and corresponding paths or next-hop addresses. This information is essential for: Packet forwarding: Routing tables enable routers to determine the optimal path for forwarding data packets from source devices to their … Read more
The purpose of secure file transfer is to ensure the confidentiality, integrity, and authenticity of files being transferred between systems over a network. Secure file transfer protocols and methods use encryption to protect data from unauthorized access or interception during transmission. By encrypting files, secure file transfer prevents eavesdropping and data tampering, ensuring that only … Read more
The purpose of a route table in networking is to provide routers and layer 3 switches with a centralized database of network destinations and the best paths or next hops to reach them. Route tables are essential for: Packet forwarding: Routing tables enable devices to make intelligent decisions about how to route data packets across … Read more
The use of NTP (Network Time Protocol) service is to synchronize the time of devices within a computer network to a precise and accurate standard time reference. NTP ensures that all devices across the network maintain consistent timekeeping, which is essential for various operations and applications that depend on accurate time synchronization. By using NTP, … Read more
ARP (Address Resolution Protocol) operates at Layer 2 (Data Link Layer) of the OSI model. Its primary function is to map IP addresses to MAC addresses within a local network segment. When a device wants to communicate with another device on the same network, it uses ARP to resolve the destination IP address to the … Read more
Address Resolution Protocol (ARP) is a protocol used in TCP/IP networks to dynamically map IP addresses to MAC addresses. When a device on a network needs to send data to another device, it uses ARP to discover the MAC address associated with the destination IP address. ARP operates at the Data Link Layer (Layer 2) … Read more
TCP (Transmission Control Protocol) offers several key features that make it a reliable and widely used protocol for transmitting data over networks. One of its primary features is reliability. TCP ensures reliable data delivery by using sequence numbers to reorder incoming packets and acknowledge received data. It includes mechanisms for error detection, retransmission of lost … Read more
SNMP (Simple Network Management Protocol) Cisco devices refers to the implementation of SNMP for network management and monitoring purposes using Cisco networking equipment. SNMP is a widely adopted protocol that allows network administrators to manage and monitor network devices, including routers, switches, firewalls, and servers. Cisco devices support SNMP as a means to gather operational … Read more
EIGRP, or Enhanced Interior Gateway Routing Protocol, is a Cisco proprietary routing protocol used in computer networks, particularly in IP networks. It is designed to support multiple network layer protocols and facilitate efficient routing within a network. EIGRP operates within a single autonomous system (AS), allowing routers within the same AS to dynamically share routing … Read more
The purpose of the POP (Post Office Protocol) protocol is to enable email clients to retrieve emails from a mail server. POP operates in a client-server model where the email client connects to the POP server to download messages from the server to the client’s local device. Once downloaded, emails are typically removed from the … Read more
