Unauthorized Access is the act of gaining entry to a computer system, network, application, or data without the owner’s permission. It can occur through stolen passwords, hacking, malware, or exploiting security vulnerabilities, putting sensitive information and systems at risk.

Switch Configuration is the process of setting up a network switch to enable efficient communication between devices in a Local Area Network (LAN). It includes configuring switch ports, VLANs, security settings, management access, and other network features to ensure reliable and secure data transmission.

Router Configuration is the process of setting up a router to enable communication between different networks. It involves assigning IP addresses, configuring routing protocols, securing the device, and ensuring data packets are forwarded correctly between networks.

VLAN (Virtual Local Area Network) Configuration is the process of dividing a physical network into multiple logical networks. It allows devices to communicate as if they are on the same network, even when connected to different switches, while improving security, performance, and network management.

A Wide Area Network (WAN) is a computer network that connects devices, offices, or local area networks (LANs) over large geographic distances, such as cities, countries, or even continents. Unlike a Local Area Network (LAN), which covers a small area like a home or office, a WAN enables communication between networks that are far apart

A Trunk Port is a network port on a switch that carries traffic from multiple VLANs over a single physical connection. It is commonly used to connect switch-to-switch, switch-to-router, or switch-to-server links while preserving VLAN information.

VRRP (Virtual Router Redundancy Protocol) is a network redundancy protocol that provides high availability for the default gateway. It allows multiple routers to work together as a virtual router, ensuring continuous network connectivity if the primary router fails.

• Router: Connects different networks and provides Internet access.
• Switch: Connects devices within the same network and enables them to communicate efficiently.

A network switch is a networking device that connects multiple devices, such as computers, printers, and servers, within a Local Area Network (LAN). It intelligently forwards data only to the intended device using MAC addresses, improving network speed, security, and efficiency.

“DHCP automatically assigns IP addresses to devices, enabling fast, efficient, and error-free network connectivity.”
