What is a hub?
In networking, a hub is a device that links multiple computers and devices together. Hubs can also be referred to as repeaters or concentrators, and they serve as the center of a local area network (LAN). In a hub, each connected device is on the same subnet and receives all data sent to the hub. The hub then forwards that data out to all other connected devices, creating an efficient system for sharing data between users.

Mạng trung tâm hoạt động như thế nào?
Mạng trung tâm là một loại mạng máy tính kết nối nhiều thiết bị hoặc nút để chia sẻ tài nguyên, thông tin, và dịch vụ. Một mạng trung tâm bao gồm một hoặc nhiều trung tâm (điểm kết nối trung tâm) và tất cả các thiết bị được kết nối khác. Mỗi thiết bị trên mạng được kết nối trực tiếp với hub, đóng vai trò là điểm trung tâm để truyền dữ liệu. Dữ liệu được gửi từ thiết bị này sang thiết bị khác thông qua trung tâm và có thể được trao đổi giữa hai thiết bị bất kỳ được kết nối với trung tâm. Trong mạng trung tâm, tất cả các thiết bị chia sẻ băng thông với nhau, nghĩa là tất cả tài nguyên đều có sẵn cho mọi thiết bị được kết nối vào bất kỳ lúc nào. Tuy nhiên, điều này cũng có nghĩa là có ít dung lượng tổng thể trên mạng hơn vì mỗi nút phải cạnh tranh để có quyền truy cập vào cùng một tài nguyên. Như vậy, điều quan trọng là phải đảm bảo rằng mạng của bạn có đủ dung lượng để đảm bảo hiệu suất tối đa. Ngoài ra, Kiểu kiến ​​trúc mạng này thường phù hợp hơn với các mạng nhỏ hơn vì các mạng lớn hơn có thể nhanh chóng trở nên quá tải và làm chậm hiệu suất tổng thể.
