port expander essay
What is a Port Expander? What does a Port Expander do? After extensive research, I have learned quite allot about Port Expanders in general and what they are used for. A Port Expander is a device that allows a single port on a computer to operate multiple devices but there are two basic types of port expansions (Internal and External). The Internal expansion slot is a single expansion plate inside the computer with multiple ports often including several USB ports and are all part of a single card that will plug into a pre-designated slot on the motherboard. The External expansion would usually be a cable that will run from the computer to a secondary box, which will have several spots that are identical to the one on the main system. The different I/O ports that are included on a port expander include: Ethernet Port, FireWire Port, DB-25 Port, Serial Port, USB Port, VGA Port, DVI Port, SCSI Port, Audio Port, Video Port, Microphone Port, RS-422 Port, Modbus Serial Port, SATA Port, SAS Port, SSD Port. After more research, I found out that there is no specific type in expander for different computers because all computers mostly have the same type of ports. The only advantage that I could come up with for using a port expander is just having multiple slots for a specific type of slot. As far as disadvantages, some port expansions only have expansions for one type on I/O port and sometimes specific expansions require more GB in the hard drive which means that the more devices that you have plugged in can result in the devices running slowly.

    A port expander is a device that allows one port on a computer system to connect to multiple devices. There are two basic forms of port expanders: internal and external. An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees is the expansion plate containing multiple ports. An external device plugs into the existing port and then has multiple places to connect. When not part of a computer system, these devices are commonly known as splitters.…

    There are no certain types of ports for the many different types of computers now days. Port expanders are computer hardware that allows more than one device to be able to connect to a single port on a computer. The two basic types of pot expanders are the internal and the external. I found that there was a girl on this website by the name of “Cameron head geek”. He is a person that she was able to talk to about the port expanders and at that time he told her that “Well……. MAC’s and PC’s have the same ports. FireWire used to be super popular with MAC’s, but a lot of PC’s had it as well. FireWire is pretty much phased out now days though”.…
