Hello Zoe,
What is a hub?
A hub in general terms refers to a central point of connection or activity. It can be used in various contexts such as transportation hubs, where different modes of transportation intersect, or social hubs, which are central places for social interactions.
What is a hub in computer networks?
In the context of computer networks, a hub is a basic networking device that connects multiple computers or other network devices together. Hubs operate at the physical layer (Layer 1) of the OSI model and are considered to be simple devices that lack the intelligence and functionality of more advanced networking equipment like switches and routers.
When a device connected to a hub sends data, the hub broadcasts the data to all other devices connected to it. This means that all devices on the network receive the data, regardless of whether it was intended for them or not. This broadcasting nature can lead to network congestion and inefficiency, especially in larger networks.
Hubs are often used in small home or office networks where simplicity and cost-effectiveness are prioritized over performance and security. However, due to their limitations, hubs have largely been replaced by switches in modern network setups.
In summary, a hub in computer networks is a basic networking device that connects multiple devices together at the physical layer and broadcasts data to all connected devices.

Alright, imagine you have a bunch of friends, and you all want to share and play together. Now, think of a hub as a friend who loves to pass messages. When one friend has something to say, they tell the hub, and the hub tells everyone else.
In a computer network, a hub is like that messenger friend. It takes information from one device (like a computer or printer) and sends it to all the other devices connected to the network. It's a simple way for devices to talk to each other.
But here's the thing: the hub doesn't really understand what the messages mean. It just takes whatever it gets and sends it to everyone. It's like shouting to all your friends in the playground, and they all hear you, but only the ones you're talking to actually pay attention.
So, a hub is like a central point where devices can share information, but it's not smart enough to understand what the information is about – it just helps in passing it along to everyone connected.

Just like an airport hub links various airlines, allowing passengers to switch flights and reach their final stop, a network hub operates in a similar way. It links multiple physical tech parts, which are usually located in different places, and functions as a coordinator to make sure all messages or data reach the right place. It brings together distributed systems, enabling them to communicate with each other.

Generally, a hub serves as a central linking point for numerous devices or systems.
In the realm of computer networks, a hub is a basic network component that links multiple devices, enabling them to interact with each other. When a device transmits data to the hub, the hub disseminates this data to all connected devices, permitting them to access the information. However, this implies that every device linked to the hub receives every transmission, even if the data is meant for just one device. This can cause network traffic jams and diminish performance.
In contemporary networks, switches have mostly taken the place of hubs. This is because switches have the ability to selectively route data to the designated receiver, which enhances network efficiency and minimizes data collisions.

Generically speaking a network hub is a device, place, or virtual entity where many connections come together. For Ethernet, a hub was traditionally a device to connect multiple Ethernet connections, forming (or extending) a LAN. It didn’t route or switch. It was a pretty dumb electrical device. By the early 2000’s the network switch was commonplace, and replacing hubs. The problem with hubs was that they didn’t control traffic. Think of a crowded Zoom call where you’re trying to have a conversation with 3 others but 20 other people in the same call are trying to have their own clusters of conversations! Switches came along and could identify who was talking to who (ie which computers were trying to connect to other computers via the switch) and dynamically separate those conversations. Switches are still a commonplace device in wired Ethernet networks. The hub, as an Ethernet device, is virtually obsolete.
