As the name suggests, a computer modem is a device that helps modulate the digital signals passing between a computer and the Internet. It converts the computer’s digital signals into an analog form that can travel over telephone lines and vice versa. This process is necessary because the telephone network is built to carry analog signals.
A computer modem is typically installed inside the computer, in a slot PCI, Express, or USB. External modems, which plug into an open port on the computer, are also available.
Computer modems come in a variety of speeds, the most common of which are 56 kilobits per second (Kbps), 128 Kbps, 256 Kbps, and 512 Kbps. Faster modems are also available, up to 7.2 Mbps. Modems are also available that work with satellite and wireless networks.
Most modems sold today are so-called “broadband” modems, which can send and receive data at speeds much faster than the old dial-up modems. In order to take advantage of the higher speeds, you need a broadband service plan from your ISP.
To connect to the Internet using a computer modem, you need to plug the telephone cord from the modem into the telephone jack, and the Ethernet cable from the modem into the Ethernet port on your computer. (If you’re using a wireless modem, you’ll need to plug the wireless antenna into the modem and the modem into your computer.)
Then turn on your computer and the modem. The computer should automatically detect the modem and configure itself. If it doesn’t, you may need to install the drivers that came with the modem.
Once the computer is connected to the modem, you can open your web browser and start browsing the Internet.

What is a computer modem used for?
A modem is a device that is used to connect a computer to a telephone line so that the computer can access the Internet.
What is modem short answer?
A modem (modulator-demodulator) is a device that converts digital signals into analog signals and vice versa, for the purposes of sending and receiving data over telephone lines.
What are the 4 types of modem?
There are four types of modems:
1. Dial-up modem
2. Broadband modem
3. Cable modem
4. DSL modem
Dial-up modem: This is the most basic type of modem. It uses a telephone line to connect to the internet. Because it uses a telephone line, it can only transmit data at a speed of 56 kilobits per second.
Broadband modem: This type of modem uses a broadband connection, such as cable or DSL, to connect to the internet. It can transmit data at speeds of up to 100 megabits per second.
Cable modem: This type of modem uses a cable TV connection to connect to the internet. It can transmit data at speeds of up to 400 megabits per second.
DSL modem: This type of modem uses a DSL connection to connect to the internet. It can transmit data at speeds of up to 1 gigabit per second.
What are two types of modem?
There are two types of modem, internal and external.
Internal modems are installed inside the computer, while external modems are attached to the computer via a port, such as USB or serial.
Internal modems tend to be less expensive and are easier to install, but they are also slower than external modems.
External modems are generally faster than internal modems, but they are also more expensive and can be more difficult to install.
Which type of modem is best for you depends on your needs and budget.
What does a computer modem look like?
A modem is a device that helps computers communicate with each other over telephone lines. They come in different shapes and sizes, but all modems have at least two connectors – one for the computer, and one for the telephone line.
Most modems have a built-in phone jack, which allows you to use the modem to make phone calls. They also have a status light, which indicates whether the modem is turned on and connected to the network.
The exterior of a modem is usually covered in plastic, and it has a variety of buttons and ports on the front and back. The most common ports are an RJ-11 port for the telephone line, an RJ-45 port for the network, and a USB port for the computer.
Modems also come with a detachable power cord, which you can use to plug the modem into an outlet.
What are 3 types of modems?
There are three types of modems: external, internal, and PCMCIA.
External modems are the traditional modems that plug into the wall. They come in two varieties: analog and digital. Analog modems convert the digital signals of the computer into analog signals that can be transmitted over a phone line. Digital modems convert the digital signals of the computer into digital signals that can be transmitted over a phone line.
Internal modems are modems that are built into the computer. They come in two varieties: analog and digital. Analog internal modems convert the digital signals of the computer into analog signals that can be transmitted over a phone line. Digital internal modems convert the digital signals of the computer into digital signals that can be transmitted over a phone line.
PCMCIA modems are modems that are inserted into a PCMCIA slot in a laptop computer. They come in two varieties: analog and digital. Analog PCMCIA modems convert the digital signals of the computer into analog signals that can be transmitted over a phone line. Digital PCMCIA modems convert the digital signals of the computer into digital signals that can be transmitted over a phone line.
What are the two main types of modem?
There are two main types of modem – landline and wireless.
A landline modem is connected to a phone line, while a wireless modem uses a radio signal to connect to the internet.
Landline modems are generally more reliable, and are more common in rural areas, where there may not be a strong enough wireless signal.
Wireless modems are more common in urban areas, where there are more potential customers and more competing wireless networks.
Both types of modem have their pros and cons, so it’s important to consider which type is right for you before making a purchase.
