What is the purpose of hardware x and y on the network

Hardware X (e.g., a Network Switch):
A network switch's primary purpose is to connect multiple devices within the same local area network (LAN). It receives data packets from one device and forwards them to the specific destination device on the same network segment, based on their MAC addresses. This allows for efficient communication between devices like computers, printers, and servers within a building or campus.

Hardware Y (e.g., a Network Router):
A network router's main purpose is to connect different networks and forward data packets between them. It uses IP addresses to determine the best path for data to travel from a source network to a destination network, such as connecting your home network to the internet, or connecting different departments within a large organization. Routers are essential for inter-network communication and managing traffic flow across larger networks.
