1. 邮编：
它是一种支持无损数据压缩和归档的文件格式。 Phil Katz 是 1989 年这种文件格式的开发者。今天，ZIP 是一种广泛使用的格式，并得到多种软件实用程序的支持，包括 Microsoft Windows 和 Mac OS X 提供的内置 ZIP 支持。最好的部分，ZIP 文件可以可以用任何创建 ZIP 文件的程序打开。
ZIP 文件是数据容器，其中包含一个或多个文件，这些文件以使用 Zip 压缩的压缩或压缩格式组合在一起。嗯，ZIP 档案不仅能够压缩文件；他们只需点击几下即可加密文件(受密码保护)和拆分档案。可以使用多种方法压缩或压缩多个文件，例如 LZMA、WavPack、PPMd、BZIP2、DEFLATE 等。
2. 压缩包：
RAR 代表 Roshal Archive Compressed file 是一种专有的存档文件格式。它包含一个或多个文件或文件夹。
但是，与硬盘驱动器上的普通文件夹不同，RAR 文件需要第三方软件才能打开和解压缩存档的内容。它是 WinRAR 存档器的原生文件格式，它以压缩形式存储多个文件——您需要做的就是解压缩其内容以访问文件。 RAR 通常比 ZIP 文件的默认支持更擅长数据压缩。
ZIP 和 RAR 的区别：
| SR.NO | ZIP | RAR |
|---|---|---|
| 1 | ZIP is an archive file format created by Phil Katz as a standard format for lossless data compression. | RAR is a proprietary archive file format for lossless data compression developed by Eugene Roshal. |
| 2 | It is free and open standard with many implementations and is supported almost everywhere. | It is not free and requires a third party tool called WinRAR archiver to compress/decompress files. |
| 3 | The rate of compression of ZIP is lower than that of the RAR format. | The rate of compression of RAR is better than that of the ZIP format. |
| 4 | ZIP offers a password based protection. | RAR doesn’t offers a password based protection. |
| 5 | ZIP files can be created with several programs such as WinRAR, WinZIP, Freebyte Zip etc. | RAR files are limited to only one program that is WinRAR. |
| 6 | ZIP uses the ZIP 2.0 encryption algorithm which is relatively weak. | RAR uses the much effiicent AES-128 encryption. |
| 7 | Filename extension are .zip and .zipx. | Filename extension are .rar, .rev, .r00, .r01. |
| 8 | ZIP uses DEFLATE compression algorithm to compress data which is less efficient than the newer compression method. | RAR uses a compression algorithm which is substantially better and efficient than the DEFLATE compression method. |
