FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Data compression can dramatically decrease the amount of storage a file takes up. For example, in a 2:1 compression ratio, a 20 megabyte (MB) file takes up 10 MB of space. As a result of compression, administrators spend less money and less time on storage.

Detailed explanation-2: -The main advantages of compression are reductions in storage hardware, data transmission time, and communication bandwidth. This can result in significant cost savings. Compressed files require significantly less storage capacity than uncompressed files, meaning a significant decrease in expenses for storage.

Detailed explanation-3: -Compression reduces the size of a file, often without appreciable loss of information. It can be either lossless or lossy. A smaller-sized compressed file can be restored to its larger form–in its entirety or with some data loss, depending on the compression type–by decompression.

Detailed explanation-4: -What is compression? ( A) To compress something by pressing it very hardly (B) To minimize the time taken for a file to be downloaded (C) To reduce the size of data to save space (D) To convert one file to another Answer Correct option is C.

Detailed explanation-5: -Compression methods like ZIP and RAR scan a file from top to bottom in order to recognize similar or repetitive patterns. Duplicates are replaced with a unique identifier much smaller than the original word, so the overall size of the file is reduced.
