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 any computer? The answer is they are all the same. In today’s modern world, any port expander you buy will work with both MAC and PC computers, making them more versatile than ever.

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......

An internal expander has a connection inside the computer. It is usually found on the motherboard, and the only part the user sees is the expansion plate containing multiple ports. An external port expander is common on desktop systems. A single expansion plate will have multiple ports, often several USB. 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. In the non-computer world, splitters are very common. Extension cords and power strips are in nearly every modern home. Both of these devices will split a single outlet to multiple devices. Cable splitters are also in many homes, allowing a single coaxial cable to provide cable television to multiple sets. Some systems may even use a A/B box, a device that connects multiple sets of devices to the same system, but switches between them by flipping between the A or B mode these devices are all doing the same basic job that a port expander does. The expander will connect to a single spot, but have multiple connections for devices.

...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.

...paper: Port Expander “A port expander is a hardware device designed to utilize more than one device on a single port at one time.” In layman’s terms, this can also be called a “splitter.” There are many different types of port expanders, but they can be narrowed down to two major groups; internal, and external. They are generic devices that will function no matter where they’re installed. Internal port expanders attach to your motherboard, and the user will only see the back plate. From a hardware standpoint, there is no difference in the type of computer. If the card fits, it will work. The first image in the appendix is an example of a port expander. External port expanders are not attached to the motherboard. They plug into a slot on the computer, and allow multiple devices to attach to that slot. The second image in the appendix is an example of an external port expander. One of the biggest advantages to using a port splitter is during multitasking. For example, most user interface devices are USB devices, mice, keyboards, printers, and even cell phone chargers can all be plugged into a USB slot. Therefore, the more ports you have, the more peripheral attachments you can use. On the other hand, with so many devices plugged into a single port the power source could get overwhelmed. Without the proper safety measures, an overloaded power source could “burn out” and cease functioning. Appendix Image 1: Internal Port Expander Image 2: External Port Expander...

...Port Expanders Port expanders is a hardware device designed to allow a user to utilize more than one device eon a single port at one time. It provides additional support for the input and output devices. Its most common slot is the PCI also known for peripheral component interconnect, AGP advanced graphics port, PCIe peripheral component interconnect express. It also cover audio modem riser AMR, and CNR communications network riser. The PCI slots can be used for many add ons such as video audio, I/O and storage adapters. The AGP slot was introduced as a high speed video in 1996, but in 2005 the PCI has been replaced for all of the new systems. The AGP has been imrpoving and have been reflecting changes through out the years. Note to this AGP slot it could be temporarily borrowed when creating 3D textures. This is a very important message, once the Pro AGP has been removed cover the extension with a sticker to prevent damge. The PCI Express slots began to replace both PCI and AGP slots in the new system, this started in 2005. PCI express has four types of slots: x1, x4, x8, x16. The most common version includes x1, x4, and x16. The PCIe sends information serially over on or more lanes. A lane is a group of signal paths that can collect and receive data. Full Duplex is when data is received and send at the same time. The max MBps is 8,000 for a PCIe x16. ...

...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.......

Port Expander

...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...
