Answer:
multiplexing
Explanation:
Multiplexing is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource.
Therefore, multiplexing feature will allow different communication streams to occur at the same time, without having a single data stream using all available bandwidth

Answer: MS-DOS
Explanation:
There are two methods of file compression: lossless and lossy compression. Lossless compression preserves all data but has a lower compression ratio, while lossy compression achieves higher compression ratios but introduces some loss of quality.
In digital media, there are two main methods of file compression: lossless compression and lossy compression.
Lossless compression is a method that reduces the file size without any loss of data. It works by removing redundant or unnecessary data from the file.
One advantage of lossless compression is that the original file can be perfectly reconstructed from the compressed file, which is beneficial when the integrity of the data is important.
However, a disadvantage is that the compression ratio is typically lower than that of lossy compression.
Lossy compression, on the other hand, allows for higher compression ratios by removing both redundant and non-essential data.
This results in a smaller file size but at the cost of some loss of quality. One advantage of lossy compression is that it can achieve much higher compression ratios, making it suitable for multimedia files.
However, a drawback is that the decompressed file will not be identical to the original.
