The message contains a few paragraphs of text. Which of the following will be important to the process of making sure that Bob receives this email? B. Bob's incoming email server 3. According to this chapter, which of the following concepts happens in a modern-day, end-to-end voice call between two business telephones sitting in the same office building in the Unitied States?
Use short answers to explain the difference between: 1. Synchronous and asynchronous Synchronous and asynchronous describe how data bits are transmitted and received particularly when discussing modems. Asynchronous communication refers to a communication method that is not dependant on particular timing scheme. The sending modem transmits each data bye into ones and zeros using start and stop bits to differentiate between the data bytes. The receiving modem uses the start and stop bytes to interpret the different data bytes.
Crosstalk - Undesired transfer of signals between communication channels. Waveguides - An electromagnetic feed line used in microwave communications. FTTH - “Fiber to the Home”, means that delivery of communication signal over fiber from the operator’s switch to a home or business. Simplex - A communication mode where only one signal is transmitted and always goes the same direction. Half-Duplex - A communication mode where data can be transmitted both directions on a signal carrier but not at the same time.
All NICs in the WLAN transmit their packet to the AP and then the retransmits the packet over the wireless network to its destination-or retransmits the packet over the wired network to its destination. Wireless NICs never communicate with each other directly; they always transmit through the AP. 3. Compare and contrast the two types of antennas. The two types of antennas that can be used on APs are omnidirectional antennas and directional antennas.
For a network address, what does the host portion of the address appear as in binary representation? The host portion of the address has 0 for each host bit in the host portion of the address. The network address is usually a standard way to refer to a network. 14. For a broadcast address, what does the host portion of the address appear as in binary representation?
In general, a given sensory neuron carries only one modality. 3. The classes of sensory modalities are general senses and special senses. a. The general senses include both somatic and visceral senses, which provide information about conditions within internal organs.
Encoding a signal for transmission permits the switching of an analog signal into a digital signal. A Codec converts an analog signal to a digital one for transmission over a data network (Goleniewski, 2007). There are various types of Codec (coder-decoder) to apply an analog-to-digital conversion. DIGITAL/ANALOG CONVERSION Modems (modulator-demodulator) convert digital signals into analog signals. There are different ways in which a modem converts digital signals into analog signals.
