... GIGABIT ETHERNET :
Gigabit Ethernet là chuẩn Ethernet cung cấp tốc độ 1000Mbps. Nó sử dụng
khuôn dạng khung Ethernet và dùng công nghệ Media Access Control như tất cả
các công nghệ Ethernet ... nhất được nhận dạng bởi thiết bị hai đầu.

VLAN là viết tắt của Virtual LocalAreaNetwork hay còn gọi là mạng LAN
ảo. Một VLAN được định nghĩa là một nhóm logic các thiết ... hình native VLAN thì
