A server daemon on the web server listens for http requests on port 80 and serves the page(s) requested by the user. • [1] http://whatis.techtarget.com/definition/0,,sid9_gci212964,00.html

  5. Apache Web server • An open source web server for a variety of platforms including UNIX and Windows • About 63% of web sites on the Internet run on Apache Servers • Other Web servers include Microsoft’s Personal Web Server and IBM HTTP Server

  6. Compression And Decompression • Compression is the reduction in size of data in order to save space or transmission time.[1] • This plays an important role on the Internet where we want to get things as quickly as possible; they provide a means to download information faster. • Different types of compression formats for example, tar, rar, zip • Files can be decompressed by a variety of commands such as gunzip, gzip or gtar, the method of decompression used determined by what was used to compress the files. • [1] http://searchstorage.techtarget.com/sDefinition/0,,sid5_gci211828,00.html

  7. Additional Notes • Port numbers are assigned by the Internet Assigned Numbers Authority(IANA) those ranging from 0-1023 are reserved for well known ports for example port 80 is reserved for HTTP, port 25 for smtp and port 23 for telnet.
