More and more often in different areas we hear the term "duplex". Sometimes the context in which this word occurs is so different that you begin to doubt, but how to use it? Duplex - what is it? Each specialist will answer this question in his own way.
Variety of terms
Translated from Latin, this word means "two-way." Hence the variety in the application of this term.
This name is widely used in telecommunications. If we are talking about modems, walkie-talkies, telephones, then this word is used to indicate two-way communication.
The term is used in chess, printing, construction, medicine, metallurgy and even in marketing.
It is possible to determine what the term means in this particular situation only from the context.
Duplex and printing
Duplex in a printer - what is it? It’s easy to figure this out. In fact, this is one of the printing methods in which the image is printed on both sides automatically, without human involvement. A similar technology is preserved in the MFP.
The indisputable advantage of this technique is that as a result we get a document that reproduces text or an image from two sides, there is no need to approach the device each time and turn the sheet over.
When is it rational to use the duplex method? In case you have large volumes of bilateral documentation.
Please note that this printing method is available in both laser and inkjet printers. This means that this feature is not only present in office models, it is also available for home printers.
Duplex in MFPs - what is this function and what does the whole process look like? Do not be mistaken in thinking that the device turns over each individual sheet. In fact, the duplex function is ensured by the fact that the paper passes through a different path through the same printer.
In refilling cartridges, such devices are similar to those in which there is no print function on both sides.
How to choose a duplex printer ?
Having answered the question “Duplex - what is this?”, We will now determine the criteria for the selection of equipment. First, find out for yourself what print volumes you need and with what regularity. If a large amount of print material is expected no more than 2 times a week, then the inkjet option will suffice.
But if you often need to use a printer in large volumes, you should get a laser device. It is easier to maintain, and print quality is better.
Duplex in the world of wallpaper
With the start of repairs in the apartment often a lot of questions arise. The choice of wallpaper is also striking in its diversity. Having understood the difference between vinyl, paper and non-woven wallpaper, we decide that you can breathe out calmly. We arrive at the store fully equipped, but again we hear the question from the consultant, “what do you prefer - duplex or simplex?”.
And again, we grab hold of our heads! How are they different? Wallpaper duplex - what is it?
And this is just one of the options for paper wallpapers that are chosen most often. Their advantages are obvious. Low cost, high environmental friendliness. All these are arguments in favor of the paper version.
What to choose?
But what is the difference between a duplex and a simplex? Both options reflect the structure of the wallpaper. Simplex is a single-layer web, which explains its subtlety and low strength. When using such wallpaper, it is necessary to carefully prepare the walls, since any irregularities will be visible.
Duplex, in turn, is a multilayer option. Wallpaper stand out with higher strength and resistance to external influences.
Coarse fiber and embossed duplex - what is it? Such wallpapers differ not only in appearance, but also in the method of manufacture.
Embossed duplex - what is it? Perhaps this is the most environmentally friendly material among all types of wallpaper. In its manufacture practically no chemically aggressive substances are used. By the way, these materials are often used for processing walls, they are popular.
Real estate duplex
When choosing urban and suburban real estate, we are increasingly confronted with the concept of a duplex house. What it is? In common people, there are similar concepts regarding the apartment. What is it, try to figure it out further.
First of all, we decide what we are talking about cottages. In fact, this is a house divided into two sections, with two separate entrances, relatively independent communications.
Such buildings are designed for two families. Sometimes a duplex is considered as a private semi-detached (actually semi-detached) version of a townhouse.
Layouts can be completely different and are limited only by the imagination of architects and designers. However, most often on the ground floor there are common rooms, such as a kitchen-studio, guest rooms, utility rooms. The personal space of family members — children's rooms, bedrooms, is often taken to the second floor. Speaking about this type of real estate, one cannot help but recall the film of the same name, in which a young couple bought a two-story mansion in a decent area at a ridiculous price. The only minus of the purchase was an old woman who rented a second floor from the owners and constantly got them with her requests ...
Term in medicine
Duplex in medicine also means duality. The ultrasound scan of the same name has been widely used, which is based on a combination of Doppler and traditional research.
Classical ultrasound gives the specialist the opportunity to examine blood vessels, and Doppler ultrasound reflects the flow of biological fluids.
The most common is BCS duplex. What is this abbreviation that many patients may take by surprise? By BCS is meant a brachiocephalic stem or brachiocephalic vessels.
Research procedure
Along with duplex, a study using classical doppler is also used to diagnose disorders of intracranial cerebral circulation. This method appeared much earlier and still has not lost its significance.
The procedure for the patient is simple and painless. The main thing is to ensure the correct position of a person: with his head slightly raised. For this, the most ordinary couch is suitable.
The study itself is carried out by a sensor lubricated with a special gel, which ensures smooth movement on the skin of the subject. The information received is read by a specialist doctor from a monitor of a duplex ultrasound machine.
In the last decade, the development of technology allows the use of a modern research method at affordable prices. There are no complications or side effects after duplex scanning.
Duplex BCS: what is it?
This term means color duplex scanning of the cranial sections of the brain, brachiocephalic arteries. This is the most advanced ultrasound diagnostic method. It can guarantee the most accurate result and clarity of images.
The state of the vessels and their structure is completely scanned by a duplex apparatus. Thanks to this, the doctor can make the correct diagnosis. If you have complaints of headache, dizziness, memory loss, inability to concentrate, causeless fatigue, tinnitus, loss of consciousness, diagnosing the nature of the pathology will also help this device.
As you can see, the term "duplex" is very widespread. This word is used to describe many things, from printers and walkie-talkies to sophisticated medical equipment.
