A cable is a bundle of wires used to transmit electricity or data.
They can carry electrical power, internet signals, or television broadcasts.
Cables are made with metal conductors (like copper) and insulated coverings.
There are many types, including power cables, coaxial cables, and fiber optics.
They vary in thickness, flexibility, and purpose depending on their use.
Cables are essential in homes, industries, transportation, and communications.
Fiber optic cables use light to send data at high speeds over long distances.
Modern wireless technology still often depends on wired cable infrastructure.
History
↓↓
The concept of the cable dates back to early electrical experiments in the 18th century.
In the 19th century, cables were used for telegraph communication across continents.
The first transatlantic cable was laid in 1858, connecting Europe and North America.
With electrification, power cables became key for delivering electricity to homes.
Coaxial cables were developed in the 20th century for radio and television.
Later, fiber optic cables revolutionized telecommunications in the 1970s and beyond.
Today, undersea cables connect the global internet across oceans.
Cables continue to evolve with new materials and faster transmission capabilities.
