These are the types of modems that are widely used today
The role of modular and demulator alias modem is quite vital in this digital age. Especially, in sending data online. The modem itself apparently has a number of types based on how it is installed, the type of connection it contains, as well as the network it has.
Although different, each type of modem has the same function, which is to send data boldly. In this article, we will mention all the types of modems that exist one by one. Who knows, you need one of these to send come boldly based on the specific conditions you are experiencing.
Want to know what are the types of modems? Let's see directly below.
Based on the Installation
The modem can be installed in two ways. First, installed in a computer or laptop. And secondly, installed in the outer area of ??the laptop or computer CPU. The installation method makes the modem divided into two types. The two types of modems are
Based on the Modem Network
Based on the network it has, modems are divided into two types. The two types of modems are wireless modems and cable modems. Both types of modems have their own special features. You can see the special features of both below
A GSM modem is a type of modem that supports 3G HSDPA networks. In his day, this form of modem was usually in the form of a USB stick that needed to be plugged into a USB port on a computer. This modem was quite popular at the time but is now starting to be abandoned as people switch to 4G network. In the market, these modems are sold at varied prices, starting from Rp. 60 thousand up to Rp. 100 thousand.
In addition to fast, this modem is also equipped with special protection. The protection makes this type of modem difficult to accept. Another advantage of this modem is the separation between the data and mobile connection lines. The separation makes internet and mobile connections more stable and does not interfere with each other. This type of modem is no longer used in line with the loss of CDMA network in Indonesia because it is focused on 4G LTE network
This is a type of modem commonly used for computers aka PCs. The internet connection that this modem produces is so fast, surpassing the dial-up internet connection. In addition, this modem can also be used to talk on the phone, without having to disconnect the internet connection in it.
This one modem is further divided into two types, namely ADSL and SSL. ADSL aka Asymmetric Digital Subscriber Line is a DSL modem that is commonly installed with Ethernet cards. This type of modem is very suitable for downloading, because the download speed is very high.
Meanwhile, SDSL alias Symmetric Digital Subscriber Line is a type of DSL modem that is capable of transmitting digital data via copper cable and telephone network. This modem has a very high speed, either when loading or unloading data. This type of DSL modem is usually sold to those from the business class.
Before using this modem, make sure your computer has an Ethernet card installed. Also make sure the cable on your cable TV uses a coaxial cable that is attached to a cable splitter. The use of the cable will make the internet connection flow smoothly, either from the modem to the computer or vice versa.
The role of the modem is very important in this internet age. That is apart from the advantage of this thing being able to send data boldly. The modem itself has a number of types based on certain criteria. Starting from how it is installed, the network of the modem, to the type of connection.
Nine of them are already listed above. Although both can send data, using the above modem has its own advantages and special features. You can wear one of them according to your needs. Hope this article is useful, yes
Definition of Modem
Modem stands for Modulator Demodulator. Where these two words have the meaning that the Modulator is the part that serves to convert the information signal into a carrier signal that is ready to be sent, while the meaning of the Demodulator is the part to separate the information signal from the carrier signal received well. In other words, a modem is a type of two -way communication device.
External Modem
An external modem is a device used for a computer to access the internet where data coming from a computer in the form of a digital signal will be converted into an analog signal. So that if the modem receives data in the form of analog signals will be converted into digital signals and then will be processed better by the computer. These analog signals can be transmitted using telecommunication media such as telephones and radios
Analog Modem
As the name suggests, the function of this analog modem is as a tool to form an analog signal and then converted into a digital signal
ADSL modem
ADSL modem comes from the abbreviation Asymetric Digital Subscribe Line is a device to access the internet and use analog phones simultaneously. Where how to use it is assisted using a connecting tool called Splitter. The function of the splitter in ADSL is to eliminate interference so that the results can run simultaneously, that is, can use the internet and can also use a regular telephone. But do not collide with each other.
The Meaning of Modem Is
What is a modem (modulator demodulator). In general, the definition of a modem is a communication device that serves as a two -way communication tool so that the Internet network can be accepted by computer/ mobile devices better.
In this case the modulator is the part of the modem that serves to convert the information signal into a carrier signal that is ready to be transmitted. While the demodulator is part of the modem that serves to separate the information signal from the carrier signal so that it can be received properly.
From the explanation of the definition of modem above we can know that the function of the modem in general is as hardware that changes two -way communication. The functions of the hardware are as follows:
Hardware that can convert digital signals into analog signals, and vice versa.
Hardware that serves to connect devices to a network.
Hardware that serves to perform modulation and demodulation activities.
Hardware that serves to compress data sent through signals.
A tool that serves to check data packets and communications.
