Summary
This chapter began with an introduction to the computer memory subsystem, the MOSFET, and the capacitor. We examined the circuitry that implements the DRAM bit cell. We reviewed the architecture of DDR4 memory modules and the operation of multichannel memory controllers. Other types of I/O devices were introduced, with a focus on high-speed differential serial interfaces and their ubiquitous use in connection technologies such as PCIe, SATA, USB, and video interfaces.
Popular video standards were presented, including VGA, DVI, HDMI, and DisplayPort. We looked at the Ethernet and Wi-Fi networking technologies as well. We concluded with a discussion of standard computer peripheral interfaces including the keyboard and mouse. The chapter concluded with a description of an example modern motherboard, highlighting some of its interesting features.
With the information presented in this chapter, you should have a solid general understanding of modern computer components from...
