Table 5.3.1: External Interface of GPIO core 5.4 UART 16550 Core The UART (Universal Asynchronous Receiver/Transmitter) core provides serial communication capabilities (the data format and transmission speeds (baud rate) are configurable) with a modem or other external devices using a serial cable and RS232 protocol. The UART core uses a shift register to convert between serial and parallel data. Using UART is advantageous as serial transmission of digital data through a single wire is less expensive

runs from all network devices. The basic form of concentrator is the hub. As shown in Figure; the hub is a hardware device that contains multiple, independent ports that match the cable type of the network. Most common hubs interconnect Category 3 or 5 twisted-pair cable with RJ-45 ends, although Coax BNC and Fiber Optic BNC hubs also exist. The hub is considered the least common denominator in device concentrators. Hubs offer an inexpensive option for transporting data between devices, but hubs

Unit 1 Exercise 1: IP Addressing Scenario 1. What subnet range/s should be used? One requirement to consider when choosing that one mask provide enough host IP addresses to support the largest subnet. Doing so the number of host bits (H) defined by the mask must be large enough so the 2h-2 is larger than or equal to the number of host IP addresses required in the largest subnet. To accommodate the growing subnet you will need at least 8 host bits. Eight host bits would be enough because 28-2=254

IP networking 12/17/2013 IP Addresses Classes and specific-Use IP Address Space An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.[1] An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: "A name indicates what we seek. An address indicates where
