Which of the following is a lossless compression algorithm?A. PNGB. Run-length encodingC. Compression artifactD. MP4

B. (Run-length encoding)

Explanation:

Run-length encoding compresses data by reducing repeating data. For example, in a text file, if there are 20 instances of the word "is", the program will store the value 20, as well as all the positions where it appears. The file can be fully reconstructed using this stored data when required, so no data is lost.

Both PNG and MP4 are lossy compression formats that reduce file sizes by irretrievably removing some part of the file, and Compression artifacts are noticeable distortions in a file caused by lossy compressions. So A, C, and D are not correct options.

Hope this helps!

some have built technology like spoofed call blockers into their networks, so there's nothing you would even have to install.

this happens because the number is known for scamming, they don't want it to me known as "scam likely." perhaps it's just a telemarketer. maybe it's an identity thief. it might even be a scam artist.  

either way, "scam likely" is probably not an old friend whose number you forgot that you saved. it's your wireless carrier's way of letting you know: answer at your own risk.

explanation:

to combat the seemingly rising epidemic of spam callers in the u.s., the nation's four major wireless carriers have been trying out new methods to reduce the number of unsolicited calls americans receive each day.

hope this . mark me brainliest.
