Page encoding is a method of transmitting data from server to your browser (the client). Most simple case is plain transmission with no special encoding used. Most other encodings are various types of compression.
Most used output compression (encoding) on PHP sites is GZIP which can be turned on by a single line of PHP code:
PHP
ob_start('ob_gzhandler');
GZIP compression allows to shrink most HTML pages down to 30% of original size. Of course, extra CPOU processing power is necessary as a trade-off (but usually it's small enough).
