Wireline or cabling is like a long rope that carries information from one place to another. Just like when you use a string to talk to someone far away, wireline is used to send important messages or data from one device to another. It's like the Internet's superhighway, carrying information between computers and devices so that we can send emails, watch videos, or connect to the world wide web. These "ropes" are made of metal or plastic and can be thin as a strand of hair or as thick as your arm. They are very important for modern communication, allowing people to stay in touch with each other from across the globe.
