A port replicator is a device that contains common computer ports including the USB, parallel, serial and PS/2 ports. It may also have additional features such as a headphone jack and an Ethernet controller. It allows users to easily connect their notebook computers to peripheral devices. The peripheral devices could include printer, scanner, keyboard, mouse and monitor. These are first connected to the port replicator and then to the notebook computer rather than connecting them directly to the notebook computer. The port replicator is convenient for those that travel frequently because it allows them to connect their portable computers to one device as opposed to connecting it to all the different peripheral devices.
The port replicator works by duplicating all of the ports on a notebook such as parallel and serial ports. It also contains several different types of each port making it easy to attach the peripherals. Users simply have to attach all the required devices to the port replicator after which they should close the display panel on the notebook and make sure the notebook ports are aligned to the replicator ports. After this, the notebook should be gently pressed down to make sure its securing tabs are locked into place. The display panel can now be opened and the notebook computer used. It does not matter whether the notebook is on or off when connecting or disconnecting the port replicator.
A port replicator allows users to convert their notebook computers to desktop computers. This is essential because manufacturers of portable computers usually save on space and weight by leaving out certain features such as CD/DVD-ROM burner. In this way, it is similar to a docking station. However, there are several differences between a port replicator and a docking station. For example, the docking station contains additional slots that can be used to add storage devices and expansion boards. It is also more versatile than a port replicator because it can be connected to the portable computer using a cable while the replicator has to be in direct physical contact with the computer.
However, the port replicator also has several advantages. A good example is that it increases the number of ports that one can use to attach peripheral devices to a portable computer. Another advantage is the fact that it is not necessary to unplug devices when the user travels with their notebook computer. All that is needed is to unplug the port replicator from the computer. It therefore saves a lot of time and prevents problems that are associated with constant un-plugging and plugging.
