3 Technology and components This chapter details the technology and components available in the system. Topics: • USB features • HDMI 1.4 USB features Universal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and peripheral devices like mice, keyboards, external drivers, and printers. Let's take a quick look on the USB evolution referencing to the table below. Table 2. USB evolution Type Data Transfer Rate Category Introduction Year USB 2.
Speed Currently, there are 3 speed modes defined by the latest USB 3.0/USB 3.1 Gen 1 specification. They are Super-Speed, Hi-Speed and FullSpeed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specification retains Hi-Speed, and Full-Speed USB mode, commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to maintain backward compatibility. USB 3.0/USB 3.
