• Principles of receiving - transmitting data: Computers on the network
will be connected to the central device called a hub.
• Connected computers should be less than 100 meters cable long.
• The system extension: Each hub can be connected 4, 8, 16 to 24
computers.
• Advantages: Network installation and maintenance is easy. If there is
any damage, it can be easily checked and the center can cut off the
damage computer in the network without affecting the network.
• Disadvantages: It is a lot of cost network. System expansion in the
future is difficult. Each time of the extension is associated with other
computers in the system.
