Programs You Need

If you are new to downloading programs over the Internet, you probably have never heard of file compression. In order to speed up the process of downloading programs, many software publishers compress their programs for transfer over the Internet. All of the downloads posted in the TeAch-nology.com Download Center are in one of three formats:

1. .exe (PC);

2. .hqx (Mac);

3. .zip (Compressed File).

.hqx and .exe files will be ready for installation immediately after they are downloaded, but .zip files must be decompressed with a decompression utility. Here are the most popular, free decompression utilities available.
