The image appears to be an educational diagram explaining the basic functions and differences between three types of network devices: hubs, switches, and routers. Here’s what the image indicates about each device:
- Hub: A hub is a simple networking device that broadcasts all incoming data packets to every connected device, regardless of the destination MAC address. It’s depicted as sending the same data to devices A, B, C, and D.
- Switch: Unlike a hub, a switch is intelligent enough to filter and forward data packets based on their destination MAC addresses. This means it only sends the data to the specific device it is intended for, improving network efficiency and reducing collisions.
- Router: A router operates at a higher level than switches and hubs. It routes data packets not just based on MAC addresses but also using IP addresses. It can connect multiple networks and manage the data traffic between them using protocols like BGP (Border Gateway Protocol).
The note at the bottom of the image states that the functions of these devices are not completely separated, and higher-level equipment includes the functions of the lower-level equipment. This means routers can perform the functions of switches, which in turn can perform the functions of hubs.

The image is a diagram of a network consisting of hubs, switches, and routers. The functions of each device are as follows:
Hub: A hub is a central device that connects network devices. All devices connected to a hub can communicate with each other. When a hub receives a data frame, it transmits it to all ports.
Switch: A switch is similar to a hub, but it only transmits data to the device connected to each port. A switch uses MAC addresses to determine which port to transmit a data frame to.
Router: A router is a device that connects two or more networks. A router uses IP addresses to determine which network to transmit a data packet to.
In the image, each device is connected as follows:
- Computers A, B, C, D: Each computer is connected to a hub or switch.
- Hub: The hub is connected to a switch.
- Switch: The switch is connected to a router.
The image also includes a description of the type of data that each device handles:
- Hub: The hub transmits all data frames to all ports.
- Switch: The switch uses MAC addresses to determine which port to transmit a data frame to.
- Router: The router uses IP addresses to determine which network to transmit a data packet to.
