What is interfacing, how does it apply to your technology?

Interfacing refers to the ability or capacity of two objects or items to be brought together to form a function together or a surface forming a common boundary between two adjacent regions, forms, bodies, etc.In the computer science and technology fields, interfacing refers to the point of interaction or communication between two devices or a user and a device.In our world of the constant whirring and buzzing of mobile phones, PDA's and laptop computers, interfacing is something that people and devices take part in perhaps thousands of times in a day without realizing the significance of it all and how seamlessly it all pulls together.For our purposes, there are mainly two types of interface in the technology world: user interfaces - or the interaction between humans and a device such as a computer and physical interfaces - or the interfaces between the actual hardware components.

Some of the most often used and most common physical interfaces (each of which will be discussed) are: USB, Firewire, CAT5 (Ethernet), printer, coaxial cable, and more recently, high definition interfaces like HDMI and DVI.Other forms of non-physical interfaces include wireless connections such as Bluetooth and Wi-Fi.


USB - USB is a form of interface available on most computers now.It allows for high speed transfer of data (video, audio, and others) from a portable device such as a digital camera or camcorder, PDA or handheld, and many others.USB 2.0 is a USB interface that allows the data transfer to occur more quickly and accurately than previous versions.

Firewire - Firewire is used mostly for getting high quality video and audio signals from a digital camera or camcorder to a computer for proper editing and usage.It is much faster than USB and is intended for the audio and video files to remain together so that there are no problems with timing once the information has been put on the computer.

CAT5 - CAT5 or more commonly known as Ethernet is used for most hard (not wireless) high speed internet connections to computers.This interface allows for rapid data transfer and allows information to be downloaded from the World Wide Web and even through networks containing many other computers.Some newer houses even have built-in networks that allow them to connect many computers to each other to transfer information and share files.This interface allows for more efficient and useful home and office computer networks.

Printer Cable - Printer cables are also a common interface and allow users to connect computers to their printers to print materials from the computer.These are however, becoming scarcer and are being replaced by USB cables that take up less space and allow for quicker data transfer.

Coaxial Cable - This is also a very common form of interface that is used in television, satellite and cable connections.It allows the information to come into the home through a receiver of some type or a modem.The receiver or modem then transfers the signal into another type and allows it to be transferred to the device through another interface.

HDMI and DVI - HDMI and DVI are newcomers to the interface team and are used in high quality high definition video and television sources.They allow the device playing the video or receiving the television signal to transmit the digital signal to the high definition receiver, television or projector.

There are other types of interfaces that are important in our modern world..Among these are newer wireless connections that achieve the same result as other types of interface but without the wires needed to connect them.These include wireless internet connections, Bluetooth phones, PDAs and other devices and computers with Wi-Fi connection capabilities.All of these things allow for our daily activities to run more smoothly and function they way we want them to.
