A "call" is a way to communicate with someone using a phone. When you make a call, you dial a number, and if the person answers, you can talk to them in real-time. This is a quick and direct way to share information or catch up with friends and family. In addition to regular phone calls, there are also video calls, which allow you to see the person you’re talking to. Apps like Zoom and Skype make it easy to connect with people anywhere in the world. Video calls are especially useful for meetings or staying in touch with loved ones.
