What is fax? Explain in detail, what does fax mean

I've seen it somewhere else! Fax refers to: In image communication, fax is a kind that people are more familiar with.

We often see "Xinhua News Agency Fax**" in newspapers, and the news of the day can be transmitted from Beijing to all parts of the world very quickly. In addition, there are facsimile copies of handwriting, documents, and diagrams, newspaper facsimile for original newspapers, and so on. Fax is a technology that transmits still images or text symbols over a wired circuit or wireless circuit.

The principle is that the sender decomposes the image or file to be transmitted horizontally and vertically into a number of tiny units (pixels) and converts each pixel into an electrical signal in a certain order, and then transmits it to the receiver through a wired or wireless transmission system, and the receiver converts the received electrical signal into a pixel of corresponding brightness, and records it line by line and little by little in the same order, and can synthesize an image or file that is exactly the same as the original.

A way to transmit information requires a fax machine, through which it is sent to the other party.

Fax is a communication method in which text, charts, photos, etc. are recorded on the paper and other still images, which are turned into electrical signals through scanning and photoelectric conversion, transmitted to the destination through various channels, and obtained a copy of the record similar to the original sent at the receiving end through a series of inverse conversion processes, which is called fax.

A communication method in which still images such as text, charts, and photographs recorded on paper are converted into electrical signals through scanning and photoelectric conversion, transmitted to the destination through various channels, and a series of inverse conversion processes at the receiving end to obtain a copy of the record similar to that of the original being sent, which is called fax.

Fax has been the fastest growing non-phone in the past 20 years.

Telecommunications services. Static images recorded on paper, such as texts, charts, and photographs, are converted into electrical signals through scanning and photoelectric conversion, transmitted to the destination through various channels, and a copy of the record similar to the original is obtained at the receiving end through a series of inverse conversion processes.

Methods of communication. It's called fax.

Fax is the fastest growing non-telephone telecommunications service in the past 20 years.

The first step is to put the content you want to fax into the fax machine, and of course open the lid before you do it.

Generally, the fax machine will prompt you how to place the document, and the fax machine we use is to face the text down (as is the case with the general fax machine).

Just put the content you want to fax according to the prompts, and the content you want to fax is downward!

Then there is dialing, there are two ways here, the number is not written down separately when faxing, you can dial first.

Then press the monitor button, which is equivalent to pressing the speakerphone key, the fax machine will have a voiceover, or if you don't need the voiceover, you can directly lift the phone (in fact, you can dial the number first and then put the file to be transmitted, but you must grasp the speed, don't wait for the ** to connect the signal has been given, the content has not been put well, so it is bad, the general recommendation is to put the fax content first! In short, as long as you make sure to put the file away before the ** is connected, there will be no problem. ）

Some fax machines are automatic, dial through will directly give the fax signal, hear the piercing "drop" sound is a signal, generally this signal is continuous, "drop--- at this time press the "fax start" button, the fax will be automatically transmitted, don't care!

There is also a kind of**fax together, the number dialed is answered first, **after answering the tell-the-phone tell someone you want to send a fax, ask her to give you a fax signal, pay attention to also wait until you hear the fax signal to remember the sound of "drip--- before you can press the "fax start" button to start transmitting.

Another way to dial is to dial directly from the machine, that is, just like we usually call, pick up the handset to dial, and then wait for the fax signal.

After dialing, you hear the "Drip--- signal, and press the "Fax Start" button.

Hang up the handset, the fax will be automatically transmitted, don't worry about it!

Generally, the fax speed is not very fast, so wait patiently.

Wait for the fax machine to spit out the fax content and the fax will be sent, and that's it! ~

Finally, we should cover the lid of our fax machine to prevent dust and other things from entering it, which will affect the service life.

Fax (is the abbreviation of facsimile, sometimes called telecopying) refers to the transmission of scanned printed materials (text or images), usually with a line connected to a printer or other output device. The original document is scanned and converted into bits** by a fax machine, which treats the transmitted content (text or image) as a separate, deterministic image. In this digital form, the information is transmitted as an electrical signal through the ** system.

The machine receiving the fax restores the code image and prints out a copy of the document.

The fax machine is to convert the documents that need to be faxed into digital signals using Hoffmann coding through photoelectric scanning technology, and then convert them into audio signals after modulation, and then transmit them through the traditional ** line. When the receiver's fax machine receives the signal, it restores the signal and prints it out, so that the receiver receives a copy of the original sent document. To sum it up, it's when sending:

Scan the image -- > generate a data signal -- > compress the digital information -- > modulate it into an analog signal -- > send it to the ** network for transmission When receiving: receiving the analog signal from the ** network -- > demodulating it into a digital signal -- > decompressing the digital signal into an initial image signal -- > printing.

Fax is a device and communication technology that transmits electronic documents through a line or network. It can be used to transmit still images such as text, charts, etc. over long distances. The working principle of a fax machine is:

1.Place the file or ** that needs to be transferred on the file table or automatic feeder of the fax machine; 2.A fax machine uses an optical converter to convert a document or ** into an electronic signal; 3.

These electronic signals are then transmitted to the receiver's fax machine via a ** line or network; 4.The receiver's fax machine then converts the received electronic signal into a file or ** output. Fax technology is widely used for its ability to transmit documents quickly over long distances, faster and more convenient than mail, and more economical than post.

It is mainly used for the transmission of various texts, files and other information between enterprises and between enterprises and individuals. At present, with the development of Internet technology, e-mail has gradually replaced fax, but fax is still used in some demanding business environments, because fax has the following advantages:1

Safe and stable: Fax is only transmitted on a dedicated line, which is more secure and reliable than e-mail. 2.

Traceability: Each fax has a unique sender and recipient, and a fax activity report is generated for easy information verification and confirmation. 3.

Fax signature: The facsimile signature has a certain legal effect in contract documents, etc. 4.

Convenient and easy to use: the fax machine is simple to operate, the threshold for use is low, it is relatively friendly to everyone, and the computer can also be used without liquid loss. To sum up, fax is a kind of file transmission technology, which uses ordinary lines or networks to quickly transmit text, images and other information to the receiver at a distance, with safety, reliability, ease of use and other excellent combustion points, and is still widely used within a certain range.

Hopefully, the above introduction will help you understand what fax is, how it works, and the main application scenarios.

Hello, fax is a means of communication that transmits documents or images over a **line. The fax machine is bright and scans the paper document or image early, converts it into an electronic signal, and then sends it to the receiver's fax machine through the ** line, and the receiver's fax machine converts the signal into a paper document or image for printing. The emergence of fax machines has greatly facilitated people's communication and file transmission, especially in commercial and ** institutions.

The advantages of fax are fast transmission speed, low cost, no loss of information during transmission, and the operation of the fax machine is simple and easy to learn. However, with the development of Internet technology, fax machines have gradually been replaced by more efficient communication methods such as e-mail and cloud storage.
