I/O Ports, Devices and Descriptions

Identifying the ports:

1/8-Inch Audio Mini-Jack. The 1/8-inch audio mini-jack is used by sound cards and motherboard-integrated sound for speakers, microphone, and line-in jacks, To avoid confusion, most recent systems and sound cards use the PC99 color coding listed as follows: * Pink—Microphone in * Light Blue—Line in * Lime Green—Stereo/headphone out * Brown—Left to right speaker * Orange—Subwoofer
USB Port Types, Speeds, and Technical Details
There are three standards types of USB ports you need to know: * USB 1.1 * USB 2.0 (also called Hi-Speed USB) * USB 3.0 (also called SuperSpeed USB)

VGA
VGA is an analog display standard. DVI
The DVI port is the current standard for digital LCD monitors. The DVI port comes in two forms: DVI-D supports only digital signals, and is found on digital LCD displays. HDMI
Video cards and systems with integrated video that are designed for home theater use support a unique type of digital video standard known as High-Definition Multimedia Interface (HDMI).

PS/2 (Mini-DIN)
PS/2 ports (also referred to as Mini-DIN ports) are used by PS/2 keyboards, mice, and pointing devices.

Parallel (LPT)
The parallel port, also known as the LPT (Line Printer) port, was originally designed for use with parallel printers.

Ethernet Port (RJ45)
An Ethernet port is a jack or socket on a computer that allows the use of an Ethernet connector. These ports are essential in allowing the creation of local area networks (LANs).

Removable Memory * CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. * Memory Stick is a removable flash memory card format, launched by Sony in October 1998, and is also used in general to describe the whole family of Memory Sticks. * Secure Digital (SD) is a non-volatile memory card format developed by the SD Card Association (SDA) for use in portable devices. * The microSD removable miniaturized Secure Digital flash memory cards

SCSI
SCSI (Small Computer Systems Interface) is a very flexible interface because it can accommodate many devices in addition to hard disk drives. Currently, SCSI interfaces, either on the motherboard or as add-on cards, are found primarily in servers and are used for mass storage (hard disk, tape backup), although you might encounter workstations and PCs that use SCSI interfaces for devices such as * High-performance and high-capacity hard drives * Image scanners * Removable-media drives such as Zip, Jaz, and Castlewood Orb * High-performance laser printers * Optical drives * Tape backups…...

An internal expander has a connection inside the computer, typically on the motherboard, and the only part the user sees in the expansion plate containing multiple ports. An external device plugs into the existing port and then has multiple places to connect. Now days there are no specific types of ports for different computers. Pretty much all computers from PC to Mac have all the same ports on them. One example of a port that was more specific just to Macs is the firewire, though these days firewire is rarely used. There are advantages and disadvantages of using a port expander. An advantage is that you get more ports to use. SAS takes one port and makes many out of them. A disadvantage is that a lot of the time they are external and can be annoying by being in the way. Also , if your power source isn’t good enough it could cause problems. When you add more devices it takes up more power, the power source can only handle so many extra ports.

...PORT EXPANDERS Kay Bey TB143p ITT Tech In this paper we will explore what port expanders do for your computer system. 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......

It is derived from Mac OS X, with which it shares the Darwin foundation, and is therefore a Unix-like operating system, by nature. In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The operating system uses roughly 500 megabytes of the device's storage. Version 4, announced in April 2010, introduced multitasking as well as several business-oriented features, including encryption for email and attachments. At the WWDC 2010 keynote on June 7, 2010, Apple announced that iPhone OS had been renamed iOS. Apple licenses the trademark for "iOS" from Cisco Systems (who own IOS), the same company with which Apple had earlier settled a dispute over the "iPhone" trademark. iOS 4 was......

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, it will...

Port Expanders

...research 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......

Identifying I/O Ports and Devices

...Identifying I/O Ports and Devices •Serial Port: A serial communication physical interface through which information transfers in or out one bit at a time. Once very commonly used for connecting an external modem or mouse to a PC, very few new computers will come with one unless specifically ordered that way. •PS/2 Connector: The most commonly used connection for keyboards and mice to a PC compatible computer system. •Parallel Port: Sends several data signals simultaneously over several parallel channels (as opposed to the Serial Port). Once the most common interface for connecting a printer to a computer, these are also now non-existent in a modern PC. •Game Port: The traditional connector for video game input devices on x86-based PCs. •Ethernet/RJ45: Most people consider this their network jack, internet connection or hardline. These ports are typically used to connect twisted pair (more commonly referred to as Cat5e) cable (or we could just say, "Plug in a network cable that gets you onto the internet"). •Modem/RJ11: A physical interface often used for terminating telephone wires. Once standard issue with every desktop PC and laptop, new computers will often be without a modem/RJ-11 port unless specifically ordered that way. •VGA Port: Acronym for Video Graphic Array. The most common connection for external monitors, but not necessarily the most preferred as it carries an analog signal. •S-Video: Separate Video (not Super Video) carries the video data as two......

...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. ...

Android vs. Ios

...October 25, 2014 Android or iOS, Which Will You Pick? You check your phone bill online and notice you are eligible for an upgrade. Good timing too, the Nokia 3310 that you have been using since 2000 was on its last leg. So you go and look at the new phones that are out and there are so many to choose from. But you want the best of the best, brand new phone, so you do some research. What you find is that Android and Apple are the big names in the game. You end up picking an Android phone, I will tell you why. Apple has been building computers since 1976, but they decided to try their hand at smartphones in 2007, releasing the iPhone. Microsoft, Palm, and Blackberry already had smartphones on the market by then, but the iPhone was the first to offer a touch screen. Apple focused on speed and consistency between apps. There was a lot lacking in the iPhone. It did not support 3G, you couldn’t copy and paste, it did not support third party apps, it had minimal buttons, and it didn’t have a customizable home screen. (IOS: A Visual History) However, no one seemed to care, Apple sold 3.7 million by 2008. Over 500 million iPhones have been sold worldwide, as of June 2014. (How Many IPhones Have Been Sold Worldwide) Everything Apple does is proprietary, so only Apple products will work with Apple products.
