...Port Expander A port expander essentially allows one to become two. What I mean by that is it allows more than one device to connect to a single port. Expanders are equivalent to splitters or extension cords in everyday life. They are usually inside the computer on the motherboard, with the only visible part of it being the extension plate showing multiple ports. Some example of the type of ports that we’ve covered and that I’m familiar with are: Ethernet Port Firewire Port Serial Port VGA Port Audio/Video Ports SATA Port DVI Port USB Port DB-25 Port Microphone Port Port expanders are pretty generic, meaning that they’re compatible for almost any PC. There is not a specific expander made for the numerous number of computer brands on the market today. The advantages and disadvantages sort of go together when talking about port expanders. They do allow you to connect more devices at one time but it also slows those devices down. Depending if the port has a 3GBps or 6GBps, all the devices had to share that speed, rather than being used individually and using all of the particular speed for one device. In most cases, buying port expanders are more convenient than trying to find a computer that comes with that many ports for a decent price. The only true downside you could run into would be the amount of power you have available on your computer. There are only so many ports you can use at one time before you overload your computer. Once it overloads...

There are two 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 that contains multiple ports. As for an external device, it plugs into the existing port and then has multiple places to connect. The most common versions are used for USB and Ethernet ports. There are numerous types of ports that have available port expanders for them. Here is a list that I have compiled: * Ethernet port expander * Firewire port expander * DB-25 port expander * Serial port expander * USB port expander * VGA port expander * DVI port expander * SCSI port expander * Audio port expander * Video port expander * Microphone port expander * RS-422 port expander * Modbus serial port expander * SATA port expander * SAS port expander * SSD port expander Port expanders are generic devices that can be used with any computer as long as the computer has the port for which you are trying to use and expander for.

...Port Expander I had never heard of a port expander before this class, but after much looking, I’ve found out what a port expander is and what it does. “ A port expander is a hardware device designed to allow a user to utilize more than one device on a single port at one time. For example, the device may allow seven devices to connect to one serial port.”(Computer Hope, 2016) It still didn’t make much sense to me, even after reading about it. As I went along finding more information, the more sense it made. What I found about this item is that additional ports receive and send data into a parallel format, which means it needs to be converted to a serial format. I found on the internet sixteen different port expanders, those would be SCSI port expander, audio port expander, VGS port expander, SATA port expander, Ethernet port expander, Modus Serial port expander, SSD port expander, SAS port expander, DB-25 port expander, USB port expander, VDI port expander, Microphone port expander, Video port expander, and Serial port expander (termpaperwarehouse, 2016). As far as if the port expanders are made for specific types of computers, what I’ve found are mixed answers online for this one. So for my own conclusion, I’m going to say they are generally basic, but doesn’t mean it will work with all computers, because a port expander doesn’t actually introduce any new hardware, just introduces a connection. It seems there are advantages and disadvantages to using a port expander...

...Aaron Boggs NT1110 Mr. Greene Unit 4 Research Paper 1: Port Expanders With such a wide variety of port expanders it is easier to say that pretty much every port is expandable. There are big port expanders that require racks to be put in, small ones that look like toys, some will let you use more than one monitor and others that can be expanded over a hundred times. I will take about a couple of these ports that have surprised me with their ability. One of the things I have learned is about the USB port expanders. The computer can have up to 127 USB ports. Not only can they do that but you can get all types of expanders for cheap. You can get one that holds four more ports and also looks like a doll or other toys from a small car to skateboards. You can also get one that more grown up that is just a regular black case, and with the ability to link so many together they are a great tool. No to mention that the speed of a USB port can be real fast and their popularity makes them easy and cheap to get. SCSI can be expanded also this is called a Daisy Chain. The amount you expand depends on the type of SCSI you use. Even though more and more of the hardware used today uses newer technology like the USB and wireless networks this technology the SCSI is still a useful tool in the IT world. Wireless routers are an amazing port expander. You can have your printer, game consuls, tablet, laptop and home computer all connected with wireless technology. These are not the...
