A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch. The transmitter uses a simple encoding scheme that uses a higher amplitude to encode 1 and a lower amplitude to encode 0, sending 1 bit in each bit time. The bit rate is 2000 bits per second (2000 bps). Which of the following is true on this circuit? B.
C. Layer 3 8. A. Layer 1 9. F. Layer 6 10. C. Transmission E. Internet Chapter 2 review questions 1. D. Connect each device to a centralized LAN switch using UTP cabling.

Continuity Tester - is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. 13. Category 5e/6 Cable - is a twisted pair cable for carrying signals/ is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the
Cite three advantages of a wireless network. User mobility, simple installations, no cables. 25. What are the most common types of equipment that are used to establish a broadband connection to the ISP? Cable Modem and a DSL modem.
The network layer then uses its protocol (IP) and translates that www.yahoo.com into an IP address. The network layer is also in charge for determining the best route through the network in order to get to the IP address destination. The data link layer is, unlike the other two which are virtual, a physical address with is permanently encoded to a device through its network card. The data link layer is a unique identifier to each computer in a network. Thus a MAC address is the only address that will always remain the same, transport and data layer address can change depending on the network.
