A LAN (local area network) is a network of computers and other devices that are connected together and located in a relatively small geographical area, such as a home, office, or school. The purpose of a LAN is to enable devices to communicate and share resources, such as printers, files, and internet connectivity.
In terms of structural networking, this refers to the physical layout and configuration of the devices and connections within the LAN. This can include the type of cables or wireless technologies used to connect the devices, the placement of devices, such as routers and switches, and the overall architecture of the network. Proper structural networking is important to ensure that the LAN is efficient, reliable, and secure. It can also help to ensure that the network is scalable, meaning that it can easily be expanded or modified as needed to accommodate additional devices or changes in usage patterns.
A WiFi access point (AP) is a device that allows wireless devices to connect to a wired network and access the internet. It acts as a bridge between the wireless devices and the wired network infrastructure, and it is typically used to provide wireless connectivity in areas where it is not possible or practical to run Ethernet cables.
Wi-Fi access points typically have one or more Ethernet ports for connecting to the wired network and one or more antennas for transmitting and receiving wireless signals. They may be standalone devices that can be plugged into a wall outlet or network port, or they may be integrated into other devices such as routers or switches.
When a device such as a laptop, smartphone, or tablet wants to access the internet over WiFi, it sends a request to the access point, which then forwards the request to the wired network. The access point also handles the transmission of data between the wired network and the wireless device, ensuring that the data is delivered to the correct destination. WiFi access points can be configured with various settings such as the wireless network name (SSID) and security settings, and they can also be managed remotely through a web interface or other means.

A PoE (Power over Ethernet) switch is a network switch that is equipped with the ability to provide power to devices over an Ethernet connection. This allows devices such as IP cameras, wireless access points, and other network devices to be powered through the same cable that is used to transmit data.
PoE switches use the standard Ethernet cables and connectors to transmit both data and power, and they are designed to comply with the IEEE 802.3af and 802.3at standards for PoE. They typically have a number of ports that can be used to connect devices, and each port can provide a certain amount of power, depending on the capabilities of the switch and the requirements of the device. PoE switches are commonly used in networks where it is not practical or cost-effective to install separate power cables for each device. They are also useful in situations where it is desirable to be able to remotely power on and off devices, such as in security camera systems or wireless networks.

A media converter is a device that is used to convert the physical form or signaling of a network communication channel. It is typically used to connect two different types of networking equipment or to connect a device to a network that uses a different type of media than the device is capable of using.For example, a media converter might be used to convert a copper Ethernet connection to a fiber optic connection, or to convert a Gigabit Ethernet connection to a Fast Ethernet connection.
edia converters can also be used to convert between different types of fiber optic cables or to connect devices that use different networking protocols, such as Ethernet and Token Ring.
Media converters are often used in situations where it is not practical or cost-effective to replace existing networking equipment, or when a device needs to be connected to a network that uses a different type of media. They are commonly used in enterprise networks, data centers, and other situations where flexibility and compatibility are important.
