Answer :
In the accelerated hub architecture, the fast end of the hub is called the "uplink port."
An uplink port on a hub is designed to handle higher bandwidth or provide connectivity to other network devices or network segments. It allows for faster communication between the hub and other devices, such as switches or routers.
They operate at the physical layer of the network and simply replicate incoming data to all connected ports without any intelligence or network segmentation. As a result, hubs do not have a concept of uplink ports that provide higher bandwidth or connect to other network devices.
Hubs have multiple ports that are essentially equivalent, and any of these ports can be used to connect to devices within the same network segment. The data received on one port is replicated and sent to all other ports, resulting in all connected devices receiving the same network traffic.

Final answer:
In an Accelerated Hub Architecture, the Northbridge is the fast end of the hub. It facilitates faster data transfer for high speed peripheral buses. The Northbridge also handles communication to the southbridge which controls slower peripheral buses.
Explanation:
In Accelerated Hub Architecture or AHA, the fast end of the hub is often referred to as the Northbridge. The Northbridge is a chip that controls high speed peripheral buses.
It facilitates faster data transfer and overall improved performance. To understand this better, picture the motherboard as a city where the CPU is the city center and the buses are the highways. The Northbridge is essentially like a highway interchange facilitating swift data transfer.
The term Northbridge is derived from the way that the chip is portrayed in schematic diagrams of a motherboard where it is often located to the 'north' of the PCI bus.
Remember, the purpose of the Northbridge is isn't just to link the CPU to the memory, but also to handle communications to the 'southbridge' which controls slower peripheral buses. Therefore, the 'Northbridge' and 'Southbridge' are part of the same system, but function at different speeds and handle different types of data.
