...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...

...Research Paper 1 : Port Expander A port expander is a device that allows one port on a computer system to connect to multiple devices. There are two basic types of port expander: internal and external. The internal expander has a connection inside the computer, typically on the motherboard. The external device plugs into the existing port and then has multiple places to connect. When not a part of the computer system, these devices are commonly referred to as splitters. For example, the device may allow seven devices to connect to one serial port. Types of ports available on the expander hardware 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 There are no specific types of ports for different computers in technology today. That being said, all the computers from PC to Mac have all the same ports so one type of port expander should connect to that specific port on any type of computer. Port expanders offer the advantage of allowing more devices of a particular port type to be utilized at the same time. The downside or disadvantage to this is that all those devices will share the output for that single port that the expander was connected to. For example, a 3 Gbps port would then...

...Port Expander “Port expanders are devices that allow one port on a computer system to connect to multiple devices. There are two basic forms of port expander: internal and external. An internal expander has a connection inside the computer, while the external connects to the outside the computer through an existing port via USB.”(What Is a Port Expander?) The use of a surge protectors or aka splitters is used to connect multiple devices so that they can get power from the wall outlet in order to work. While on the other hand port expanders get there power from the computer instead from a wall outlet. There are different types of port expanders: Ethernet port expander hardware, FireWire port expander hardware, DB-25 port expander hardware, Serial port expander hardware, USB port expander hardware, VGA port expander hardware, DVI port expander hardware, SCSI port expander hardware, Audio port expander hardware, Video port expander hardware, Microphone port expander hardware, RS-422 port expander hardware, Modbus Serial port hardware, SATA port expander hardware, SAS port expander hardware and SSD port expander hardware. Some port expanders can work on all computers while other port expanders can only work on some computers it is depended on what kind of motherboard that computer is using. “The advantages of using port expanders are that you get more ports to use. SAS expanders take one port and make many out of them. SSD are so much faster, often capable of reading 200MBPS or...

...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...

...Port Expanders Roydrick L. Rogers ITT Technical Institute 17th April 2014 Port expander is a device that allows a port on a computer to connect to multiple devices. There are two basic types of port expanders, internal and external. An internal port expander has a connection on the inside of a computer, connected to the motherboard and the only part the user sees is the expansion plate containing multiple ports. External port expander has connections on the outside of the computer and is more obvious, a cable plugs into the existing port on the computer and has multiple places to connect other devices on an external hub or similar device. The advantages of using port expanders are that you have more ports then normal to use. For example SAS expanders take one port and make many more out of them. If you have one at 6gbps and you expand it to connect 8 devices, throughout all 8 ports the total is only 6gbps or about 80MBps. Some of the disadvantages of port expanders are external port expanders, not only do you have to buy them at a local store or online, but you also have the cable that has to be plugged into one of your USB ports. The cable itself can be annoying, some other factors are; the loss of one of your USB ports (depending on what type of expander you are using this might limit your abilities to plug in other USB devices). As for the question of; are port expanders made for specific types of computers or if they are generic devices that will work with...

We will explain whether or not port expanders are specific to a computer or generic in nature. We will also analysis the advantages and disadvantages are when using port expanders for your computer. What is a port expander? A port expander is a device that allows your computer to be connected to many other devices at one time. (What is a port expander, 2014) There are two basic forms of port expanders; internal and external. The internal port expander is an expander the normal computer user cannot see. It is located inside of the computer and it is normally connected to the computer’s motherboard. The only identifier that this type of port expander is connected to your computer is the expansion plate displaying multiple ports. This plate is normally located on the back of your computer and allows you to pull in your external devices. The external port expander is an external device that is plugged into an existing port that allows you to connect multiple additional ports to your computer. Since these ports are not a part of the computer system itself, they can also be known or classified as splitter. Splitters are common in the world that is not filled with computer language; for instance an extension cord or cable boxes that us an A/B switch to convert from one set of channels to another. Port expanders work the same way; they allow your computer...

...According to Webster’s a port expander is computer hardware that allows more than one device to connect to a single port on a computer. Some port expanders are internal and some are external. The internal ports are inside the computer normally attached to the motherboard. As for external port expanders, they plug into the existing ports. On a port expander you may have several ports. These ports may be as follow: PS2 port, Serial port, parallel port, and video port. Some may even have more, it varies by brand. You may also purchase expander ports that have only video and audio. There are several different types, it all depends on your need. Port expanders are largely generic but will not necessarily work with any computer. Compatibility varies based on the existing ports of the computer and the operating system used. Well, depending on what you are using it for there are different kinds of advantages and disadvantages. There can be an advantage as well as a disadvantage to using port expanders. If you are using it on a desktop or home computer one of the advantages is the ability to allow more devices of a particular port type to be utilized at the same time. One disadvantage is if you have a 3Gbps port, with a port expander installed that can support up to seven devices, only has a max of 3Gbps throughput bandwidth divided by each device; or however many are plugged in and being used. The more devices you have plugged in the less throughput bandwidth that port can use. Here are three...

Port expander are hardware device designed to allow a user to utilize more than one device on a single port at one time. It’s able to connect several devices to one serial port, for example connecting mouse, and keyboard when you only have one USB slot to use, you would use a port expander to fix this problem. There are several different types of port available for expander hardware, but to list a few we have USB, Ethernet, Audio, SAS, VGA, Microphone, DVI, and Video ports.( see pictures below). Port expanders are made generic so it’s compatible with most computers if not all, as long as the computer has the ports for which you are trying to expand for. With anything there are always disadvantages, and advantages. Disadvantages to port expanders are that whenever you have it fully connected it takes away performance from all devices since they all share the same bandwidth. Example if you have a 6GBps port expander which can connect up to 8 devices, when all connected creates a traffic jam making the performance slow creating a bottle neck effect. Also most are external, requires a lot of power, for this reason you possibly overload/ruin the power supply, or PC may not start till all is disconnected.

The internal expander has a connection inside the computer, most likely on the motherboard the only part the user will see in the expansion plate with many ports. The external device plugs into the existing port and then it has multiple places to connect. When they are not a part of the computer system they are known as splitters. Internal port expander is common on desktop systems. With single expansion plate will also have multiple ports, often serval USB ports. Now on the inside the computer ports are all part of a single card that will plug into predesignated spots on the motherboard. These ports on the motherboard are programed to handle a single port, but the card will connects to the external ports that handles the routing so the system is not over loaded. External port expander is much more obvious. On commercial systems there are large numbers of different types of port expanders. Servers often have different power and load requirements than standard user system. Which will commonly use external devices to route and monitor usage through various ports. These systems range from one similar to a home system all the way to specialized internal hardware that is built to connect to external expander.

...PORT EXPANDER In this research paper I will give a brief description along with an in-depth understanding of port expanders. For starters, it’s best to have some sort of mental picture of what a port expander actually looks like. Take for example, an external hard drive that has a USB 2.0 male port cord coming from it, now remove the external hard drive end from the cord and replace it with a 4-in-1 USB 2.0 female port end. What you’re left with in the end is a cord similar to Fig. 1-1 located in the index section of this paper. So as you can see, instead of having a device on the other end, a port expander would have several female USB 2.0 ports. These female ports allow for other devices to be plugged in all while utilizing one USB 2.0 computer port. Which proves to be convenient when having to work with several external devices and a computer with only one port. Another advantage of port expanders is that, not only are they made for specific brands of computers, but generically made as well. These generically made port expanders allow for a universal fit for all computers. The downside is that for one, port expanders are dividing the bandwidth/data from that computer port into however many devices connected to it. Unfortunately this in turn is reducing the overall speed and performance of your computer.

...Port ExpandersA port expander is a device that allows you to use one port of your computer to connect many more devices to your computer. There are two basic forms of port expanders: internal and external. An internal expander has a connection inside the computer. An external device plugs into the existing port and then has multiple places to connect. The way they work is, you basically plug the expander to one of the ports on your laptop or desktop and then you have multiple copies of that port on the other end, which you can use to connect more devices at the same time. Port expanders exist for many different devices and not only for computers. Outside the computer world they are known as splitters, extension cords, cable splitters, etc. They are usually generic and made to fit various types of devices or computers. One of the advantages in using a port expander is that you can use more devices even if your computer does not have the required ports for them. I’m not sure there are too many disadvantages in using one, they may overwhelm the motherboard with too much energy consumption, and that could mess with your power source. Their prices usually range from a couple of dollars to thousands, depending on what your needs is. USB Port Expander for PS3. It expands the 2 USB ports in the PS3 to 5. TOSHIBA I/O EXPANDER.
