The first version returns the size of the specified data type, and the second returns the size of the specified value. As you can see, if you want to know the size of a data type, such as int, you must enclose the type name in parentheses. If you want to know the size of a value, no parentheses are needed, although you can use them if you want. To see how sizeof works, try the following short program. For many 32-bit environments, it displays the values 1, 4, 4, and 8.

unavoidable ISI. However, there are no power overshoots so these filters allow the use of more efficient amplifiers, with less power back-off, than the raised cosine filters discussed above. It is important to note the difference between the filtering that takes place in each modulator/demodulator leg, as opposed to the rest of the analog radio sections. Since the I and Q signals at the input to the quadrature modulator are filtered separately in each I and Q input leg, then each of the I and Q legs of the modulator will low-pass-filter at BW symbol rate (0.5 ). But when the I/Q stream is modulated onto the IF thus creating a double-sideband signal this will cause BW symbol rate (1 ). So the actual shaping of the digital QPSK (or QAM) signal will take place in these modulator sections (usually composed of a modem), with the rest of the radio design merely used to maintain the modulator-generated spectral shape, while adding as little distortion as possible to the already predefined signal. Thus, the actual analog filtration that occurs within the IF and RF sections of the analog transmitter and receiver units may be significantly wider than BW symbol rate (1 ), especially in block up- and down-converter designs. 2.5 Designing with Modulator/Demodulator ICs

3-D acceleration hardware Specialized chips and boards designed to accelerate the display of three-dimensional environments by taking over computing tasks from the CPU. They include a specialized graphics processor, a microprocessor specifically designed for rendering 3-D scenes, and extra memory to store geometry, fonts, textures, and other building blocks of 3-D graphics. The current generation of high-speed 3-D games would not be possible without it. 3-D graphics

// A simple map demonstration. #include <iostream> #include <map> using namespace std; int main() { map<char, int> m; int i; // put pairs into map for(i=0; i<26; i++) { m.insert(pair<char, int>('A'+i, 65+i));

As it applies to a generic interface, covariance is the feature that enables a method to return a type that is derived from the class specified by a type parameter. In the past, because of the strict type-checking applied to generics, the return type had to match the type parameter precisely. Covariance relaxes this rule in a type-safe way. A covariant type parameter is declared by preceding its name with the keyword out. To understand the implications of covariance, it is helpful to work through an example. First, here is a very simple interface called IMyCoVarGenIF that uses covariance:

2. Enter the router command to delete your configuration file in NVRAM: __________. 3. You have executed the show startup-config command and see the following message: %%Non-volatile configuration memory is not present . Which of the following answers are correct about these two things (choose two) A. B. C. D. E. F. This command displays the running configuration in NVRAM. This command displays the saved configuration in NVRAM. This command displays the saved configuration in flash. The message indicates that flash needs to be reformatted. This message indicates that NVRAM needs to be reformatted. This message indicates that there is nothing stored in this memory location.
