A digital communication system consists of a transmitter and a receiver

To use the analog telephone system for sending digital data, you must also use a modem. A modem converts digital data into analog signals for transmission and converts received signals back to digital data.

To use the analog telephone system for sending digital data, you must also use a modem. Here’s how it works:

Digital Data Conversion: Digital data, which consists of binary ones and zeros, needs to be converted into analog signals. A modem (short for modulator-demodulator) accomplishes this task. It modulates digital data into analog signals for transmission over telephone lines and demodulates the received analog signals back into digital data at the receiving end.

Analog Signal Transmission: Analog phones transmit data over a continuous range of frequencies. The modem converts binary ones and zeros into analog frequency tones that can be reliably sent over these frequencies.

Noise Reduction: Digital systems, including those using modems, handle noise better than pure analog systems. Any error that a small amount of noise introduces can be effectively detected and corrected.

For example, when sending computer data over an analog phone line, a sending modem translates the digital data into analog signals. At the receiving end, another modem converts the analog signals back into digital data for the computer to process.

The best method for collecting information involves summarizing, paraphrasing, or directly quoting the source material, always with proper citations to avoid plagiarism and maintain credibility.

The best method for collecting information from a source is multifaceted and depends on your research objective. When considering the notes from your sources, you have the choice to summarize, paraphrase, or directly quote the information. Summarizing involves conveying the general idea of a text in a shorter form, without detailed specifics. Paraphrasing is close in length to the original text but rephrased in your own words. Direct quoting maintains the exact wording from the source and is placed inside quotation marks. Regardless of the choice made, proper in-text citation is crucial in order to credit the original author and avoid plagiarism. This practice preserves the integrity of your work and provides a pathway for readers to verify your sources.

When collecting information, it's essential to keep meticulous notes, ensuring that you clearly distinguish between your ideas and those borrowed from sources. Effective note-taking allows you to refer back to the original texts which aids in accurate quoting and paraphrasing. Moreover, the organization of source material and notes will assist in accurately citing your information sources, thus upholding your professional credibility.

Alternatively, drop to command prompt type cd\

dir /s/o:s to get a listing in ascending order.

for descending order dir /s/o:-s

Since there might be a lot of files you might want to pipe it into a text file, simply add > largefiles.txt

dir /s/o:-s  > c:\temp\largefiles.txt    (the c:\temp directory must exist, if not the command will fail. Once you're on the root with cd\ just create the temp directory with md c:\temp or via the GUI, alternatively, again add & md c:\temp into the dir command)

If you want to get fancy you can also just open the results with the & 

dir /s/o:-s  > c:\temp\largefiles.txt & notepad c:\temp\largefiles.txt
