(Universal Serial Bus) USB is a hardware interface for up to 127 peripherals that is governed by the USB Implementers Forum (see USB-IF). USB is used to attach keyboards, mice, printers, external storage, and mobile devices to the computer. It is also used for charging a wide variety of portable products (see USB power). After debuting in 1997, USB soon replaced the earlier serial port, parallel port, and Apple Desktop Bus.
Hence the option D is correct.

USB (Universal Serial Bus)
USB stands for Universal Serial Bus. It is a widely used technology for connecting devices to a computer. USB provides a standardized connection interface that allows various devices to communicate and transfer data with the computer.
Key Points about USB:
- USB is a popular interface for connecting devices such as keyboards, mice, printers, external storage devices, and many more.
- It was developed in the mid-1990s by a group of companies including Intel, Microsoft, and others to replace the older and less versatile serial and parallel ports.
- USB has become the standard interface for connecting peripherals to computers due to its ease of use, speed, and compatibility.
- USB ports are commonly found on computers, laptops, game consoles, and other electronic devices.
- USB supports hot-plugging, which means devices can be connected or disconnected from the computer while it is running without the need to reboot.
- USB cables use a unique connector design that is reversible, allowing the cable to be plugged in either way.
- The most common USB connector types are Type A, Type B, and Type C, with Type A being the standard rectangular connector found on computers and Type C being a smaller, reversible connector commonly used on newer devices like smartphones and tablets.
- USB supports multiple data transfer modes, including low-speed (1.5 Mbps), full-speed (12 Mbps), high-speed (480 Mbps), and SuperSpeed (up to 5 Gbps) for USB 3.0 and 10 Gbps for USB 3.1.
- USB also provides power to connected devices, eliminating the need for separate power adapters for many peripherals.
- USB has evolved over the years with new versions and improved features, such as increased data transfer speeds, better power delivery capabilities, and support for new device classes.
In conclusion, USB (Universal Serial Bus) is a widely used technology that provides a standardized interface for connecting devices to computers. It offers convenience, speed, and compatibility, making it the go-to choice for connecting peripherals and transferring data.
