Dialer, also known as a dialing system, is a computer program or device used to set up and control a connection between two computers. It is commonly used to connect computers to the Internet, but it can also be used to establish local area network connections. In telecommunications, it is used to initiate an outgoing call or establish an incoming connection.
There are several types of dialers: software-based, hardware-based, and portable. Software-based dialers are programs that run on the user’s computer and enable them to control the connection and dial up numbers. Hardware-based dialers are physical devices that allow users to connect multiple computers and manage the connection. Portable dialers are designed to be easily carried and used with laptop computers.
A dialer may contain a number of features such as automatic redial, modem configuration, automatic modem-detection, setting speed and customizing the dial-up connection. These features make it easier to connect to the Internet, without having to manually configure it each time.
Dialers are typically used to connect to the Internet with a low speed dial-up connection. This type of connection is becoming less common as broadband and wireless technologies become popular. Some dialers include a feature for Voice over IP (VoIP) making them suitable for use in VoIP applications.
Dialers have been in use for many years and are used in various industries, such as banking, telecommunications, and medical. In medical applications, a dialer may be used to monitor and control a medical device such as an x-ray machine or a ventilator. In banking, a dialer is used to verify customer information without the need to call the customer directly.
Dialers are still widely used in certain markets where low-speed access is available and VoIP is not. They are also used in areas with limited access to broadband. The dialing programs are usually small and depend on the operating system to dial and create the connection, making them easy to use for the majority of users.
