TestOut Networking Pro ch 3 Exam Questions and Answers 100% Solved Network Adapter (also called a network interface card or NIC) - answerconnects a host to the network medium. It is responsible for converting binary data into a format to be sent on the network medium Network adapter is responsible for - answerfor converting binary data into a format to be sent on the network medium. Which are Transceiver and a modem Transceiver - answeris responsible for converting digital data into digital signals to be sent on the medium. The type of signal the transceiver sends depends on the type of network. A fiber optic NIC sends light signals, a wired NIC sends electronic signals on a wire, and a wireless NIC sends radio signals. To receive signals, the transceiver converts digital signals from the network to digital data for the PC. Modem - answerconverts binary data to analog waves (modulation) on the sending end, and then converts the analog waves back to binary data (demodulation) on the receiving end. Network adapters are Layer 1 devices - answerbecause they send and receive signals on the network medium. They also Layer 2 devices because they must follow the rules for media access, and because they read the physical address in a frame Network adapters you choose - answermust match the network architecture you are connecting to Older network adapters - answerused an external transceiver to connect to the network media. However, all modern network adapters use a built-in transceiver. Transceiver Module - answeris used to change the media type of a port on a network device, such as a switch or a router. The following are the most common types of transceiver modules: • A GBIC (gigabit interface converter) is a larger-sized transceiver that fits in a port slot and is used for Gigabit media including copper and fiber optic. • An SFP (small form-factor pluggable) is similar to a GBIC but is a smaller size. An SFP is sometimes called a mini-GBIC. • An XFP transceiver is similar in size to an SFP but is used for 10 Gigabit networking. Media Converter - answeris used connect to network adapters that are using different media types. For example, a media converter could be used to connect a server with a fiber optic Ethernet NIC to a copper Ethernet cable. • Media converters work at the Physical layer (Layer 1). Media converters do not read or modify the MAC address in any way. • Media converters only convert from one media type to another within the same architecture (such as Ethernet). A media converter cannot translate between two different architectures. (This must be done using a bridge or a router. Converting from one architecture to another would require modifying the frame contents to modify the Data Link layer address.) MAC Address - answeris a unique identifier burned into the ROM of every Ethernet NIC. • The MAC address is a 12-digit (48-bit) hexadec
