Benefits of a USB to Serial Cable
Most devices such as computers and other computer peripherals have switched over from serial ports to USB. For people who still have devices with serial ports a USB to Serial Cable is needed. This cable is essential for those who need to connect their devices when one is equipped with only USB and the other, only with a serial port. If this cable were not made available, those consumers with older devices would not be able to use their computer with other non-USB computer peripherals.
Serial ports used to be the USB of today. A serial port transfers data through serial communication, which means that it only transfers one bit each time. Less than 2 years ago, serial ports were the communication bus for connecting modems, mice, keyboards or other devices. The main reason why the serial ports are not being manufactured on equipment is simply due to wanting to save money on the unit. Many industrial products and network equipment continue to manufacture devices with serial ports since they are less expensive and are compatible with older equipment.
The Universal Serial Bus (USB) works similarly to the serial port but allows more and easier plug-and-play. With USB connections, users can change out devices with ease and can plug in more as opposed to the serial ports. The USB also consumes less energy, which helps with longer battery life when using a laptop without power supply. The USB can be found on any computer and computer peripheral such as, cameras, PDAs, mice, scanners, printers. Anything that is being manufactured now, that can be used with a personal computer, will have a USB port.
