Port FireWire was adopted in 1995 as an official industry standard IEEE1394. FireWire widely used in digital video recorder camera (DV camcorder), external hard drives and external DVD writer.
An earlier version of FireWire is a FireWire IEEE-1394a or commonly known as FireWire 400, and also called iLink that has a transfer speed of up to 400 Mbit per second. While the latest version of FireWire is a FireWire IEEE-1394b or commonly referred to as FireWire 800 which has 2 times the speed of FireWire 400.
FireWire can be used to connect the FireWire hard drive that has a high capacity, and product CD / DVD FireWire, and is often used to transfer digital audio and high quality Digital Video.
Universal Serial Bus or commonly referred to as USB is designed to allow peripherals to be connected via a standardized interface socket and to improve plug-and-play which allows the device to be connected and disconnected without rebooting the computer.
Features of the USB is included to provide power for devices that consume low power without the need for external power supplies and allows various devices can be used without having to install special drivers for certain devices from certain manufacturers.
With the USB port is the number of parallel and serial ports for connecting a computer with a mouse, keyboard, joystick, scanner, printer via a computer cable. USB 1.0 specification was introduced in November 1995 which was promoted by Intel, Microsoft, Philips, and U.S. Robotics. Actually intended to replace the many USB connectors on the back of the computer. USB 1.1 appeared in September 1998 to address the issues raised in previous versions.
USB 2.0 specification was released in April 2000 and standardized by the USB Implementers Forum (USB-IF) at the end of 2001. Here is some data transfer rates supported by USB:
- Low Speed (Low Speed) with a speed of 1.5 Mbit per second (187 kB per second) which is used for keyboard, mouse and joystick are supported by USB 1.1 and USB 2.0.
- Full Speed (Full Speed) with a speed of 12 Mbit per second (1.5 MB per second). Full Speed is the fastest rate before the USB 2.0 specification emerged. Now all types of USB support Full Speed.
- High speed (Hi Speed) with a speed of 480 Mbit per second (60 MB per second) which is used for keyboard, mouse and joystick are supported by USB 1.1 and USB 2.0.
