IP 56 is a rating for enclosures that are subject to a variety of weather conditions. This is a standard developed by the International Electrotechnical Commission (IEC) and is a worldwide standard. In the U.S., the National Electrical Manufacturers ASsociation (NEMA) sets similar standards.

IEC Ingress Protection Standards
The IEC has a published standard 60529, which defines Ingress Protection using a two digit code. This standard has all the information about testing and applications.
The first digit indicates the protection against access to hazardous sections and whether solid objects can get into the encolosure. In other words, how hard is it to stick your finger in there and cause some trouble.
The second digit indicates the amount of protection against water.
Here are the designations for the first digit - Hazardous Parts:
0 - Non-protected
1 - Protected against access with the back of the hand (50mm size object)
2 - Protected against access with jointed finger (12 mm x 80 mm)
3 - Protected against acess with a tool (2.5 mm)
4, 5, 6 - Protected against access with a wire (1.0 mm)
Here are the designations for the first digit - Solid Foreign Objects:
0 - Non-protected
1 - Objects greater than 50mm
2 - Objects greater than 12.5 mm
3 - Objects greater than 2.5
4 - Objects greater than or equal to 1mm
5 - Dust protected
6 - Dust tight
Protection designation for the second digit - Ingress of Liquids
0 - Non-protected
1 - Water dripping vertically
2 - Water dripping, enclosure tilted up to 15d
3 - Spraying water, upt to 60d angle from vertical
4 - Splashing water, any direction
5 - Jetting water, any direction
6 - Powerful jetting water, any direction
7 - Temporary immersion in water
8 - Continuous immersion in water
You can see that an IP56 rated enclosure is protected against dust (and other small particles) and is water tight against jetting water from any direction.
Technology can refer to material objects of use to the humanity such as, machines, hardware or utensils. It also encompasses broader themes, including systems, methods of organization, and techniques. This term can be applied either generally or specifically: like construction technology, medical technology and computer technology.
The use of technology by human race began with the conversion of natural resources into simple tools. The pre-historic discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in traveling and controlling their environment. Recent technological developments, including the printing press, the media, the telephone, and the internet have lessened physical barriers to communication and allowed humans to interact on a global scale.
Information technology and computers have attained a vital position in today's world which is turning to a global village. The field of computers is a vast sea and there are many features and options available to choose from. Internet remains a constant and rapidly growing source of information on a broader spectrum. Now people don't just use web browsers to gain information but can get any piece of required knowledge from any part of the world by just a few clicks on the web sites. As information is becoming much easier to access, the need of more web sites and knowledgeable sources is on the rise. New trends of web hosting, web publishing and content blogging are taking a more important place in the world of internet.
The term Information Technology was first used in November 1981, modernizing the outdated old phrase "data processing". IT covers a broad area and is not just the domain of science related professionals but even professionals from arts and aesthetics utilize the splendors of this newly hyped source.
The early general purpose computers were made in such a way that they could easily be reprogrammed to carry out different tasks which involved plugging of switches and rerouting wirings. A number of early software designs comprised of circuits and ensured that the wires didn't fuse. The necessity for convenience eventually allowed programmers to evolve and build basic punch-card systems. Even then, teams of technicians worked together to determine where holes were to be punched to appropriately determine change of function of the hardware of the computers.
Now software development programmers produce more complex applications by utilizing microprocessors, the cycle of more power full soft-ware and capable hardware with increasing amount of memory storage and processing powers.
Over the past decades, computing has become a model of technology usage that covers various services. These include office productivity applications to process and maintain documents and records, different web portals to view and share images videos and songs, social networking sites to interact with other net users across the globe and even net instant messaging services to communicate in real time. This list simply continues to grow.
Today, information technology forms the crux of modern society and development and at its core stands software development, iPhone 12 gebraucht kaufen steering entire operations by individuals or groups of challenging professionals.
