USBkaapeli

USBkaapeli is the Finnish term for a USB cable. A USB cable is a standard for connection, communication, and power supply between computers and electronic devices. The Universal Serial Bus (USB) interface was designed to simplify the connection of peripherals to computers, replacing a variety of earlier serial and parallel port connectors.

USB cables come in various types, most commonly USB-A, USB-B, USB-C, and various micro and mini USB connectors. USB-A is the most recognizable rectangular connector found on most computers and chargers. USB-B is typically found on larger peripherals like printers and scanners. USB-C is a newer, reversible connector that is becoming increasingly common on modern smartphones, laptops, and other devices due to its versatility and ability to support higher data transfer speeds and power delivery. Micro USB and Mini USB were common for smaller portable devices like older smartphones and digital cameras.

The function of a USB cable is to transmit data and/or electrical power. Depending on the USB standard supported by both the cable and the connected devices, data transfer speeds can range from the low speeds of USB 1.0 to the very high speeds of USB 3.2 and USB4. USB Power Delivery (USB PD) is a specification that allows for significantly higher power transfer, enabling faster charging of devices and even powering larger electronics. USBkaapelit are essential for everyday technology use, connecting everything from keyboards and mice to external hard drives and charging mobile devices.
