...Port connectors may be male or female, but female connectors are much more common. Bent pins are easier to replace on a cable than on a connector attached to a computer, so it was common to use female connectors for the fixed side of an interface. Computer ports in common use cover a wide variety of shapes such as round (PS/2, etc.), rectangular (FireWire, etc.), square (Telephone plug), trapezoidal (D-Sub — the old printer port was a DB-25), etc. There is some standardization to physical properties and function. For instance, most computers have a keyboard port (currently a Universal Serial Bus USB-like outlet referred to as USB Port), into which the keyboard is connected. Physically identical connectors may be used for widely different standards, especially on older personal computer systems, or systems not generally designed according to the current Microsoft Windows compatibility guides. For example, a female 9-pin D-subminiature connector on the original IBM PC could have been used for monochrome video, color analog video (in two incompatible standards), a joystick interface, or for a MIDI musical instrument digital control interface. The original IBM PC also had two identical 5 pin DIN connectors, one used for the keyboard, the second for a cassette recorder interface; the two were not interchangeable. The smaller mini-DIN connector has been variously used for the keyboard and two different kinds of mouse; older Macintosh family computers used the mini-DIN for a serial...

...Hardware Expander Types: Internal port 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. External port expander: An external device plugs into the existing port and then has multiple places to connect. SOME EXAMPLES AND IMAGES OF PORT EXPANDERS: * Ethernet Port Expander Hardware * FireWire Port Expander Hardware * DB-25 Port Expander Hardware * Serial Port Expander Hardware * USB Port Expander Hardware * Audio Port Expander Hardware * Video Port Expander Hardware * SATA Port Expander Hardware There are no specific types of ports for different computers now days. All the computers from PC to Mac have all the same ports on them. The advantages of using port expanders are that you get more ports more ports to use. SAS expanders take one port and make many out of them. So say you have one 6gbps, and you expand it so you can connect 8 devices. The total throughput on all 8 ports is only 6gbps, or about 80MBPS. Even in regular hard drives can do 80MBPS, so in theory you could see a bottleneck here, but in practice you probably will be fine. In Some cases SAS expanders are cheaper than getting an equal number of "real" ports. Some disadvantages are a lot of them are external and that can be annoying and get in the way could use more power and if your power source isn't good enough it could cause...

...NT1110 Claudine Estes Port Expander Port expanders is a device that allows one port on a computer system to connect to many devices. There are two forms of port expanders they are internal and external. 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...

...Unit 4 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...

...What is a Motherboard? The Motherboard is the main circuit board inside the PC. It holds the CPU and memory, provides expansion slots for peripherals, and, whether directly or indirectly, connects to every part of the PC. The essential motherboard make-up includes the chipset (known as the “glue logic”), some code in ROM and the various wired interconnections between the components know as buses. The chipset is fundamental, and controls how the motherboard interacts with everything else in the system. A good chipset can be more important than the power of CPU or the amount of RAM. The ROM code includes the BIOS, which has user-changeable options for how the motherboard operates with integral and connected devices. The buses are the electrical wires that connect everything together. Motherboard designs use many different buses to link their various components. For instance, wide, high-speed buses are difficult and expensive to produce. The signals travel at such a rate that even distances of just a few centimetres cause timing problems, while the metal tracks on the circuit board act as miniature radio antennae, transmitting electromagnetic noise that introduces interference with signals elsewhere in the system. For these reasons, design engineers try to keep the fastest buses confined to the smallest area of the motherboard and use slower, more robust buses for other parts. Types of Slots on a Motherboard Motherboards are the backbone of a computer, holding different...

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. Advantages to port expanders are that it...

...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...

...A port expander is a hardware device that will allow users to utilize multiple devices on a single port at the same time. It is the same principle as using a power strip for the power in a home or a splitter for the cable. For example, if you only have 1 Universal Serial Bus (USB) port, yet you have a USB mouse and keyboard, then you can use a USB port expander to allow one port slot to become multiple ports and plug in the mouse and keyboard. Allowing multiple devices to be able to connect to a single port is a major advantage to port expanders. However, one of the biggest drawbacks is that the speed of that port is now divided throughout all the expansion ports, an example being a 3Gbps port expanded to accommodate 4 ports will now have to split that 3Gbps between all 4 ports and not 3Gbps per expansion slot. There are two types of port expanders: internal and external. An internal port expander will usually connect to the motherboard and have an expansion plate with multiple ports along the box of the computer. An external port expander will plug into an existing port (such as a USB) and will then have multiple connections off of the port expander. Port expanders are also very generic and will allow expansion on just about any computer. There are many ports available that come with port expansion hardware. Some examples are, but are not limited to, USB Port Expander Hardware, Microphone Port Expander Hardware, FireWire Port Expander Hardware, Serial Port Expander...

...Most people who use computers are clueless to the internal ways that computers work. Here we will be talking a little about why a computer user might need to be familiar with things such as the binary system, Boolean operations, and the time it takes to transfer data. The average computer user is probably not aware that the actual operations of a computer are done with a binary system. Most of the time a typical computer user has no need to think about this aspect of computers, but every now and then the underlying binary nature will manifest itself. It’s more likely they will encounter a more compact variant of the binary system, called hexadecimal (or “hex” for short). Hex can come up on a Windows error message and the hex addresses may help pinpoint the source of trouble. Hex can also be used by spammers to hide their internet addresses. Another place where hex numbers commonly occur is in hypertext markup language (HTML) code where they are used to designate colors. Boolean Operators are simple words (AND, OR, NOT) used to combine or exclude keywords in a search, resulting in more focused and productive results. Using these operators can greatly reduce or expand the amount of records returned. They are useful in saving time by focusing searches for more ‘on-target’ results that are more appropriate to your needs. The AND operator narrows the search by requiring both terms to be in each item returned. If one term is contained in the document and the other is not, the item...
