To establish a network, there are several hardware components that are required. These include:
1. Network Interface Card (NIC): A NIC is a hardware component that is installed in a computer to allow it to connect to a network. It provides the physical connection between the computer and the network.
2. Switches: A switch is a networking device that connects multiple devices together on a network. It allows devices to communicate with each other and facilitates the transfer of data between them.
3. Router: A router is a networking device that connects multiple networks together. It directs traffic between networks and provides a gateway to the internet.
4. Cables: Cables are used to connect devices to the network. There are different types of cables, such as Ethernet cables, which are used to connect devices to switches and routers.
5. Wireless Access Points: Wireless access points are devices that allow wireless devices to connect to a network. They provide wireless connectivity to devices such as laptops, smartphones, and tablets.
6. Servers: Servers are computers that provide services to other devices on the network. They can provide services such as file sharing, email, and web hosting.
Overall, these are some of the hardware components that are required to establish a network. The specific components required will depend on the size and complexity of the network.
