So they can be connected to a network. If you visit a place which does not have Wi-Fi access, then you can plug it into a Cat 5 socket. Before Wi-Fi was as popular as it is now, most motels which offered internet access had Cat 5 network sockets so guests could get Internet access.

Ethernet adapter is used to connect to the internet, hard drive is used for storage of data, and the video card is used for video processing.
An ethernet adapter is the component that allows you to connect to your internet modem or computer network. Upon connecting your ethernet cable, you will be able to access the internet or computer network to which you are connected.
To enjoy the freedom of sharing a wireless network and the internet at home, the proper networking hardware needs to be installed. First, a router needs to be connected to a cable or DSL modem. A typical home networking router includes four Ethernet ports, which could be used to connect to other computers and compatible peripherals. To connect to a router without Ethernet cables, wireless network adapter devices must be used. A PCI network adapter must be permanently installed directly onto a computer's motherboard. A USB network adapter is easier to use because it could be plugged in and out of a USB port. Some laptops have built-in network adapter technology.
An Ethernet adapter is used for connecting two electronic devices together to share information. Ethernet Adapters allow one computer to receive the same information from another computer.
An RJ-45 connector is commonly used with Ethernet cables for networking applications. It connects devices such as computers, routers, switches, and network interface cards. Adapters that utilize RJ-45 connectors include Ethernet adapters, network extenders, and PoE (Power over Ethernet) splitters, which facilitate wired network connections.

Ethernet Network Card
A wired network adapter with a port that resembles a telephone jack is typically an RJ-11 connector, which is commonly used for traditional telephone lines. However, it's important to note that a wired network adapter primarily uses an RJ-45 connector, which is larger and designed for Ethernet connections. While RJ-11 connectors can be used for DSL internet connections, they are not standard for typical wired network adapters, which generally utilize RJ-45 ports for networking purposes.
An Ethernet Cable is a 8 wires cable that connects to your computer with RJ-45 Plugs (a 8 pins plug). It is mostly used with standard, cable networks to establish communication between either your computer and another network component (router, hub, other computer) or an Internet Component (modem). A usual Ethernet Cable ranges from a 10Mbps transfer to over 100Mbps. Their maximum lenght is usually 328 feet or 100 meters, even though some special cables can be longer. That little carde you slide in your laptop is probably a wireless network adapter for laptops. It usually acts the exact same way as an Ethernet Cable and establish connection between different network components. The main advantage of a wireless network adapter is that you are not limited by the cable and it often looks nicer. The main drawbacks are that the transfer rates are a bit lower and your network security may be a bit weaker. If you have to choose between one or the other, it is better to go for an Ethernet cable if you need speed and reliability. If you need to move around a lot with your laptop, you should definetly go for a wireless network adapter (that little card.)
APC USB to Ethernet cables are used to connect devices that lack an Ethernet port, such as certain laptops or desktop computers, to a wired network. This allows for a stable and reliable internet connection, improving network performance compared to wireless connections. These cables typically support high-speed data transfer and are useful in environments where a strong, consistent connection is necessary, such as in offices or for online gaming.
A network interface card is used to connect a computer to an Ethernet network
