2033. The 'Nyquist theorem' specifies the minimum sampling rate to be
| Answer : Option D |
| Explanation : |
| The Nyquist Theorem, also known as the sampling theorem, is a principle that engineers follow in the digitization of analog signals. Any analog signal consists of components at various frequencies. The highest frequency component is an analog signal determines the bandwidth of that signal. The higher the frequency, the greater the bandwidth, if all other factors are held constant. Suppose the highest frequency component, in hertz, for a given analog signal is fmax. So, according to Nyquist theorem, the sampling rate must be at least 2 fmax, or twice the highest analog frequency component. If the sampling rate is less than 2 fmax, some of the highest frequency components in the analog input signal will not be correctly represented in the digitized output. |

'Save As' lets the user make a copy of the file in a different folder or location and make a copy with a different name. |
2038. Which type of resource does have greater probability to become shared resource in a computer network ?
| Answer : Option C |
| Explanation : |
| A shared resource typically refers to a hardware or software resource that can be accessed by one or more remote systems over a network. Hardware devices such as printers and scanners are often set up on a network for use by numerous users in an organization. Printer acts as a shared resource for a set number of computers, allowing users to send documents to the print queue, which would then send those documents to the printer. This allows multiple users to share a single or more printers on a network. This is cost-effective as printers are expensive. |
