Wireless networks have limited range. Network range depends on the type of 802.11 protocol, strength of the device transmitter and the architecture of the surrounding area. Some structures, such as walls and metal frames, reduce the range of a WLAN by 25%. However, users can extend the range of a WLAN. Repeaters forward the wireless signal to access points or routers and increase the range of a network. Speed Bandwidth and latency are the measures of computer network speed, or data transfer rate. Bandwidth is the maximum throughput of data in bits per second. Some modems support 100 Gbit/s but speed depends on the hardware and software used. Latency is the delay that network creates during the transfer data. Users have no, or very little, control over bandwidth and latency. 1 How many things does network range depend on? 2 What can reduce network range? 3 What can improve network range? 4 What two things affect speed?

A sequential circuit has one input X and four outputs Z₁ Z₂ Z3 Z4. Z1 Z2 Z3 Z4 represents the gray code encoded number equal to the number of pairs of adjacent 1's that have been received as inputs. Use the gray code that is on page 22 of the textbook. For example, if the circuit had received 7 pairs of 1's as inputs, Z₁ Z2 Z3 Z4 = 1011. In addition, the circuit resets when the circuit receives 5 pairs of 1's. Find a Moore state graph and table for the circuit.
