Is it a computer problem or a cat problem?

is a software windows hlp to rtf related file, it is a windows help file (*.HLP to RTF format so that RTF files can be processed with Word 97 2000 XP 2003.

And the disconnection is not its problem, it should be the problem of the server, you find your service provider, seek a solution, if it is several people at the same time with the route to access the Internet, it is your ** business blocked the route, just find them directly.

There is also a possibility that there is a problem with your network cable, or that the network cable connection is false. You can carefully check the network cable, network card, and cat. (Please check whether there is a problem with the network card, it is stable and unstable, and the quality of some work package network cards is not up to standard).

The situation you mentioned should not be a problem with the system, it should be a problem with your line that causes frequent drops.

Find a maintenance worker to check the outside line for you, and check the line connector in your room yourself should be able to solve the problem you said, so act quickly.

Check the ** line to see if the line with the cat is broken, I have encountered this problem. As for the windows help file, ignore it, it means that the words are missing this file, and you can't view the help.

Hoho, what's wrong with this?See you head-on.

The cat's light should be power, DSL and LAN on.

As for the drop?Hehe, is it a system problem?If it's a cat given by a broadband provider, the drive shouldn't be a problem. I think you should try reinstalling the system.

If there is a problem with the system, it is recommended to reinstall.

Is the account and password correct? And is the network cable plugged in correctly? Restart the cat.

Cat is a homonym for modem, short for i.e. modem .

A modem is a kind of computer hardware, which can translate the digital signals of the computer into analog signals that can be transmitted along the ordinary ** line, and these analog signals can be received by another modem at the other end of the line, and translated into a language that the computer can understand. This simple process completes the communication between the two computers.

Modem is the abbreviation of modulator and demodulator, Chinese called modem (Hong Kong and Taiwan call it a modem), according to the homonym of modem, affectionately called "cat".

External modem.

The so-called modulation is to convert the digital signal into an analog signal transmitted on the first line; Demodulation, i.e., the conversion of an analog signal into a digital signal. Collectively known as modems.

The English word for modem is modem, and its role is to act as a "translator" of analog and digital signals. There are two types of electronic signals, one is"Analog signals", one is"Digital signals"。The ** line we use transmits analog signals, while the PCs transmit digital signals between them.

So when you want to connect your computer to the Internet through a ** cable, you have to use a modem"Translation"Two different signals. After connecting to the Internet, when the PC sends information to the Internet, because the ** line transmits an analog signal, it is necessary to use a modem to send the digital signal"Translation"into an analog signal before it can be transmitted to the Internet, a process called"Modulation"。When the PC obtains information from the Internet, because the information transmitted from the Internet through the ** line is an analog signal, the PC wants to understand them, and must also use the "translation" of the modem, which is called "demodulation".

In general, it is called "moderation".

The scientific name is modem, and it is used for broadband dial-up Internet access.

1. All cats are modems, which are used to access the Internet through ** line (including ADSL broadband and ordinary** line Internet access), while routers are used to set up a local area network (including wireless and wired), and can also be used with cats to achieve a ** line and multiple computers to access the Internet at the same time.

The router is used to divide a network cable into several computers on the device, if you are ** line to the Internet, you need to use a cat, if several computers use a ** line to connect to the Internet then connect to the cat and then connect to the router. If it's broadband, you'll need a switch! The specific self will understand it when you use it!

Cat - professional name: modem - router for digital-to-analog conversion - to implement data routing and **.

Low voltage (your power strip).

There are two possibilities, one is the problem of the motherboard voltage; One is that there is a possibility of power connection between the cat and the computer.

You can find a multimeter to test it, and you're good to go.

"Cat" is the colloquial name for a modem.

So what is a modem?

Modem (i.e., modem) is a device for signal conversion between the computer and the first line, consisting of two parts: the modulator and the demodulator, the modulator is the digital signal of the computer (such as files, etc.) is modulated into a device that can transmit the sound signal on the first line, and at the receiving end, the demodulator converts the sound signal into a digital signal that the computer can receive. Data communication between computers can be realized through a modem and a ** line.

At present, there are two main types of modems: built-in and external.

The built-in modem is actually a computer's expansion card, which can be used by plugging into an expansion slot in the computer, and it does not occupy the computer's serial port. Its connection is quite simple, insert the ** cable connector into the "line" socket on the card, and the other interface "phone" on the card is connected to the ** machine, when the modem is not used at all, the ** machine is not affected at all.

The external modem is a cassette device placed outside the computer, it needs to occupy a serial port of the computer, and it also needs to be connected to a separate power supply to work, there are several status indicators on the external modem panel, which can be convenient for you to monitor the communication status of the modem, and the external modem is easy to install and disassemble, easy to set up and maintain, and easy to carry. The connection of the external modem is also very convenient, and the connection of the phone and line is the same as that of the built-in modem. However, an external modem must use a serial cable to connect one of the serial ports of the computer to the serial port of the modem, and this serial cable is usually shipped with the external modem.

An important performance parameter of the modem is the transmission rate, which is currently available in both 56k modems on the market, and 56k modems have become the mainstream products in the market. However, due to the limitation of domestic communication lines, as well as the fact that there are too many users and too few international exports, it is difficult to achieve the above rates in normal use, so if the transmission rate is only a few kilobytes per second or even lower when you use it, you don't need to wonder if there is something wrong with your computer or modem.

Computer cat, a common name for a modem. It is a kind of computer hardware, which can translate the digital signals of the computer into analog signals that can be transmitted along the ordinary ** line, and these analog signals can be received by another modem at the other end of the line, and translated into a language that the computer can understand. This simple process completes the communication between the two computers.

The commonly said modem (cat) is actually the abbreviation of modulator (modulator) and demodulator (demodulator), which is called modem in Chinese. There are also people who affectionately call it "cat" according to the homonym of modem. We know that the information in the computer is composed of digital signals composed of "0" and "1", while the transmission on the ** line can only be analog electrical signals.

Therefore, when two computers want to transmit data through the first line, a device is needed to be responsible for the conversion of digital to analog. This digital-to-analog converter is the modem we're going to talk about here. When a computer sends data, the modem converts the digital signal into the corresponding analog signal, a process called "modulation".

Before the modulated signal is transmitted to another computer through the carrier wave, the receiver's modem is responsible for restoring the analog signal to a digital signal that the computer can recognize, a process we call "demodulation". It is through this digital-to-analog conversion process of "modulation" and "demodulation" that remote communication between two computers is realized.
