2 Technology and components This chapter details the technology and components available in the system. Topics: • DDR4 • USB features • HDMI DDR4 DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512 GB in capacity, compared to the DDR3's maximum capacity of 128 GB per DIMM.

DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation. Figure 3. Curved edge 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 3.
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 3.1 Gen 1 achieves the much higher performance by the technical changes below: • An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below). • USB 2.0 previously had four wires (power, ground, and a pair for differential data); USB 3.0/USB 3.
Compatibility The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all, while USB 3.0/USB 3.1 Gen 1 specifies new physical connections and thus new cables to take advantage of the higher speed capability of the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as before.
• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionality Technology and components 13
