A self-extracting archive created using 7-Zip. A self-extracting archive (SFX or SEA) is a computer executable program which combines compressed data in an archive file with machine-executable code to extract the information. Running on a compatible operating system, it does not need a suitable extractor in the target computer to extract the data.

If you have a codec (Zip, 7Zip,etc) and compress files into a format and you want to give the files to someone who doesnt have the Zip codec, you can use an SFX which any PC/Mac can run. But atleast they reworded it so that is more understandble, I think all the concepts are still covered. Just in case I kept the original text up there..
A compressed executable can be considered a self-extracting archive, where a compressed executable is packaged along with the relevant decompression code in an executable file. Some compressed executables can be decompressed to reconstruct the original program file without being directly executed.
Thus, when a ZIP file is viewed in a text editor the first two bytes of the file are usually "PK". (DOS, OS/2 and Windows self-extracting ZIPs have an EXE before the ZIP so start with "MZ"; self-extracting ZIPs for other operating systems may similarly be preceded by executable code for extracting the archive's content on that platform.)

It can create and view archives in RAR or ZIP file formats, [6] and unpack numerous archive file formats. To enable the user to test the integrity of archives, WinRAR embeds CRC32 or BLAKE2 checksums for each file in each archive. WinRAR supports creating encrypted, multi-part and self-extracting archives. WinRAR is a Windows-only program.
