Before the introduction of USB, various devices were connected with the help of serial and parallel ports of computers to transfer data.

All the peripheral devices like keyboards, mouse, scanner, printers contain a unique port of its own. The major issue of these ports was the slow speed when connected to computers. The speed of data transfer between them was 120 kB/s to 500 kB/s.

Other than these problems, there are some other issues like incompatibility and multiple interfaces. That was the reason to develop USB to overcome these problems.

  • By using USB hub, length as well as number of USB ports are changed depending on the usage.

Disadvantages of Using USB

  • USB cable’s length is not sufficient.
  • An optimum speed is needed for some modern peripheral devices which is not available in the USB devices.
  • You can use USB with certain limitations.
  • At a certain time, only one message will transfer between devices.
  • USB is not supported with broadcasting.

Conclusion

USBs are the devices that are most used to build connection in different devices with laptop or computer. Most of the operating system supports this device to perform various operations.
