👉 "Digital Dial Up Internet Relay Chat," refers to a type of network where internet is accessed via dial-up modems, allowing users to communicate over a wired or wireless connection over a local area network (LAN). Typically, dial-up modems use a modem in your home or office for data transfer. The "IR" stands for Interface Revision (referencing the software interface) and "conf," which is commonly used to specify configuration files and settings for the device. This term often refers to a configuration file that describes how a system should behave when configured, including interfaces like IP addresses, protocols, and more.
