Cordless phones are a type of telephone that allows users to make and receive calls without being tethered to a wall outlet. They operate using a base station connected to a phone line, while the handset communicates wirelessly. This gives users the freedom to move around their home or office while talking, making it convenient for multitasking. Most cordless phones come with features like caller ID, voicemail, and even built-in answering machines. They typically use rechargeable batteries, so users can easily place the handset back on the base station to charge when not in use. This technology has made communication more flexible and accessible for many people.
