A port expander is a device that allows one port on a computer system to connect to multiple devices. 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. Now pretty much every computer from PC to MAC has all the same ports on them. It used to be that MAC was the only one using Firewire, but then it became available on the PCs. However, even since it became available on PCs, it has now been mostly phased out. There are advantages and disadvantages to using a port expander. The main advantage to using a port expander is that you can get more available ports to use and plug things into. I would say that using an external port expander would have an advantage of being able to be unplugged from one computer and being plugged in on another computer. The disadvantages of using a port expander are

...Motherboards The motherboard is what it says it is, the mother tied to all the systems within itself that enable the computer to communicate the data going in and out to each and every component integrated, connected, or built into the board such as, the CPU, the RAM, North Bridge, South Bridge, System Bus, Hard Drives, Cd Drives etc.   Chipsets Motherboards are commonly known to be called chipsets or their type of chipset (form) is referred by the company who manufactured them. They are composed of two main components: Memory Controller Hub (MCH) and the I/O or Input Output Controller Hub (ICH). The MCH, is the communication bridge between the CPU the RAM and some PCI Express Devices, it is also known as the Northbridge located near the top of the Motherboard. It requires a high amount of data to be transferred via the system bus. You will notice a heat sink to allow the chip to cool down otherwise it will burn through the motherboard itself. For the ICH provides data to transfer to the secondary systems, such as the USB, Audio, Mouse, Keyboard, Hard Drives etc. The ICH is also known as the Southbridge which is located near the bottom of the motherboard. System Bus The motherboard bus is also called the system bus are tiny etched lines on the motherboard and is the traffic of all data, power, control, and address that is being sent throughout the entire system.

...ISMINUR KAPUKAYA LEVEL 3 HEALTH AND SOCIAL CARE EXTENDED DIPLOMA UNIT 14 M1: Assess possible difficulties involved in the diagnosis of the disorders from their signs and symptoms. Diabetes (type 1 diabetes and type 2 diabetes) There are many different possible difficulties which can be involved in diagnosing Diabetes (type 1 diabetes and type 2 diabetes) and Stroke from their signs and symptoms. Firstly, there may be difficulties when diagnosing physiological disorders such as Diabetes and Stroke due to the signs and symptoms of both of the disorders being similar to other types of disorders. Therefore, this means that when a patient goes to their General Practitioners with the signs and symptoms of Diabetes, the doctor will need to make a few investigations before the disorder is diagnosed. They do this so that the doctor does not get the signs and symptoms of the patient mixed up with other physiological disorders. Difficulties in diagnosing Type 1 diabetes The signs and symptoms of type 1 and type 2 diabetes are having blurry vision. When a patient goes to their GP with the signs and symptoms of having blurry vision, the doctor may think that the patient has another physiological disorder. This may include having an eye disease as the signs and...

...A port expander is a hardware device that can allow multiple devices to be attached to one port on a computer via either internal or external. An internal port expander is one that is already inside of a computer or one that you can physically put inside the computer yourself, also can be located on the mother board of the CPU. An external expander is one that you can buy and just attach to the outside of the computer in an I/O port to allow the use of multiple devices as well. The advantages of this hardware is that one can use multiple devices through just one port just like one could use a multi plug extension cable to attach many different items. The disadvantage is the running speed isn’t changed at all and depending on the amount of items you have connected can run the speed down on such an expander, another disadvantage could also be the price while some expanders are quite cheap others can be very costly as well. Port expanders can be often generic, however, there are few that are computer specific the reasoning behind this is that with computer specific expanders one would have to know the type of motherboard inside the computer that would be having the expander put inside, external expanders would be the ones that are generic because they can run through ports already in the computer such as the I/O port. Different types of ports available in expander hardware are the addition of Ethernet cable ports, also ports for additional mice if needed, there is also...
