AVideo Graphics Array (VGA) connectoris a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.

DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it from the older and less flexible DE-9 connector used on some older VGA cards, which has the same shell size but only two rows of pins).

VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. In the original version of DE-15 pinout, one pin was keyed and 4 pins carried Monitor ID bits which were rarely used; VESA DDC redefined some of these pins and replaced the key pin with +5V DC power supply.

The VGA interface is not engineered to be hotpluggable (so that the user can connect or disconnect the output device while the host is running), although in practice this can be done and usually does not cause damage to the hardware or other problems. However, nothing in the design ensures that the ground pins make a connection first and break last, so hotplugging may introduce surges in signal lines which may or may not be adequately protected against. Also, depending on the hardware and software, detecting a monitor being connected might not work properly in all cases.

Computers are all about connectivity and are loaded with cables--both internally and externally--that allow data to be exchanged between the computer's components and peripherals.

• Desktop computers typically use a universal power cord for power, while laptops use power adapters, often made to the specifications of the manufacture.

• VGA and DVI cables use a series of pins to transfer video signals between devices, such as a monitor and the computer. VGA is analog, and DVI is digital.

• IDE and SATA cables transfer data between the computer's internal components and the motherboard. The cables are pretty much the same as far as speed is concerned.

• USB and FireWire cables allow peripherals to connect to your computer and transfer data at high speeds. FireWire cables can send and receive data at the same time, while USB cables cannot.

• Ethernet cables are used to join two network devices. The cable contains four thin wires that allow data to be transferred at high speeds between the devices in the form of a series of electrical pulses.

Laptop Power cables are used in laptop adapters.

All types of power cables are available:-

Also, depending on the hardware and software, detecting a monitor being connected might not work properly in all cases.

Cable quality

The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 640400px @70Hz (24MHz of signal bandwidth) to 12801024px (SXGA) @85Hz (160MHz) and up to 20481536px (QXGA) @85Hz (388MHz). There are no standards defining the quality required for each resolution, but higher-quality cables typically contain coaxial wiring and insulation which make them thicker. A quality cable should not suffer from signal crosstalk which occurs when the signals in one wire induce unwanted currents in adjacent wires, ghosting which occurs when impedance mismatches cause signals to be reflected (note that ghosting with long cables may not be the fault of the cable but may instead be caused by equipment with incorrect termination or by use of passive splitters), and other signal degradation effects; shorter VGA cables are less likely to introduce significant degradation. Some higher-end monitors and video cards featured 5 separate BNC connectors for RGBHV signal, allowing highest quality connection using five 75 ohm coaxial cables.

There are HDMI to VGA and DVI to VGA adapters, and VGA to SCART converters. For a simple VGA to SCART adapter cable to be viable, the display card must have sufficient features. Namely the ability to provide interlaced output and adjust the frequency, number of total scan lines and number of visible lines (the actual resolution) to match those of the prevailing TV standard.Signal incompatibility rises from the fact that SCART uses composite sync, so either display card must be able to do so too, or sync signals must be summed with a simple circuit. Additionally some TV sets may require 1 volt voltage on SCART pin 16 as explicit signal to use component instead of composite signal. Likewise, three conductor analog RGB signal uses composite sync on green, but a converter circuit for to achieve that is simple as well.

1. HDMI/DVI to VGA adapters do not carry the audio channel. Separate audio cables are used.

2. HDMI to VGA adapters generally won't be useful as most displays can't read analog over the HDMI port.

In today's technology-centered world, it is necessary to be able to connect your consumer electronics, such as keyboards, speakers, printers and more, to your computer. You can attach these devices to your PC using universal serial bus (USB) interface technology.USB cablesestablish communication between technological devices and allow you to transfer information as fast as 480Mbps (mega bits per second).

USB cables rely on ports and connectors to establish a connection between your PC and USB-enabled devices. The connectors on both ends of the flexible cable include contacts, which slide in easily to the receptors located on the computer and on the source device. This simple technology improves communication between devices and is essential to maximizing the use of your PC. USB cables provide quick device communication and information transfer up to 5 meters without delay. USB extension cables can establish additional device connection over 5 meters.

Not all USB cables are created equal. Multiple shapes and sizes of connectors outfit USB cables, so you must purchase the correct cable to connect your devices. Cables can be made with Type A or Type B connectors in mini, micro or standard size, and the connectors can be male or female. USB cables also come in many different lengths, so it's best to have a general idea of the distance between your devices so you can buy the right length of cable. The best cable companies also provide great help and support and supply a cable warranty.

FeaturesUSB 2.0 cables are the second generation of USB technology and are the most widely used. Double shielding technology protects these high-speed data transfer cables and blocks out interfering signals from other devices. These cables also come with different connectors. Because many consumer electronic devices include a port for a Type A connection, and most PCs include USB ports that need a Type B connection, it makes sense that the most commonly used cables consist of a Type A connector on one end and a Type B connector on the other. This standard type of USB cable will connect most devices to your PC.

Length Options

The universally supported 2.0 version of the USB cable functions optimally at or under a length of 5 meters, or around 16 feet. These cords are available in lengths of 3 feet, 6 feet, 10 feet, 15 feet and 16 feet. Depending on what you are connecting, it is best to purchase the shortest available cable to ensure fast and easy data transfer and to reduce the possibility of interference. A USB extension cable provides additional connection between devices that are separated by over 16 feet.

Help & SupportNot all connections are perfectly smooth, and not all USB cables are flawless. It is essential for USB cable companies to provide a warranty and a method of communication in case you need to return a product. Some manufacturers also provide live chat assistance, which we have found to be a very useful tool.

Printer cablerefers to thecablethat carries data between acomputerand aprinter.

There are many different types of cables, for example:

• Serial:RS-232, EIA-422
• Parallel
• FireWire
• USB

Parallel port printers have been slowly phased out, and are now difficult to find for the most part, being considered as an obsoletelegacy porton most new computers.

Those who have printers and scanners with only parallel port may still be able to connect the devices via the use of USB adapters a.k.a. Parallel-to-USB cable. Generally, FireWire's very high speeds of up to 800Mbit/s are excessive for printers.

USB 2.0 cable connects PCs or laptops to USB peripherals such as printers and scanners.
