Laptop docking stations usually contain drive bays, ports, expansion slots and connectors that enable users to easily connect their laptop to several peripherals. Some are also equipped with a Network Interface Card (NIC) for LAN (Local Area Network) connections.
By providing a single point of connection, docking stations enable laptop users to utilize a monitor, full-sized keyboard, mouse and printer when they are not on the move, thereby converting their laptops into full-fledged desktop computers. Laptop manufacturers typically design custom docking stations for each of the laptops they produce. This means that docking stations are not standardized and have to be purchased based on specific laptop models.
