The technological rampage taking place in the 21st century surely is a maddening one. With new gadgets and devices hitting the shops it is important to understand how they all connect and function to provide you with an experience like never before. All so that, they are more pleasant than they are burdensome. The cables, connectors and wires have simultaneously evolved to support such technological advancement and it becomes important to know them too.
Data cables are formed with two or more wires running together, braided, twisted or bonded to from a single unit. The function of data cables is to transmit information between systems such as personal computers, servers and other electrical hardware. Different electronic devices require a specific set of wires and cables that support their functions and characteristics.
We have the DVI (digital visual interface) cables that are designed for carrying uncompressed digital video data. This interface uses a digital protocol in which pixels are transferred through binary data. It reads the number specified in a binary and provides brightness accordingly to that pixel. In this way, each pixel in the output device corresponds to each pixel in the display device. A DVI cable consists of four twisted pairs of wires. There is no packetisation, no compression and no support to transmit only the changed parts in the image.
A DVI cable advanced from the VGA (Video graphics array) connector cable. A VGA cable is a lead used for transmitting video signals. It is most commonly used to link computers with monitors. However, it is now used on some high definition televisions only.
And the most advanced of all cables happen to be the
HDMI cables. HDMI stands for high definition multimedia interface. Various new companies like wireworld are producing these cables that offer an audio and visual interface for the transmission of uncompressed digital data. It connects digital audio/video sources like set top boxes, DVD players, camcorders, gaming consoles etc to compatible digital video devices like monitors and televisions. HDMI supports, on a single cable, any uncompressed TV or PC video format, including standard, enhanced, and high-definition video. They revolutionized the way technology worked since their inception in 2003. The best thing about them is that they are compatible with DVI signals. So if you wish to use an HDMI with a device that uses DVI, you can easily do so and enjoy a quality experience.
