| INTERNET DICTIONARY - LETTER "O" | |
| OCLC | See: Online Computer Library Catalog |
| octet | An octet is 8 bits. This term is used in networking, rather than byte, because some systems have bytes that are not 8 bits long. |
| OEM | original equipment manufacturer - A misleading term for a company that has a special relationship with computer producers. OEMs buy computers in bulk and customize them for a particular application. They then sell the customized computer under their own name. The term is really a misnomer because OEMs are not the original manufacturers -- they are the customizers. |
| OH | Off Hook - OH is a modem indicator light that tells you the phone line is open and ready for communications. |
| offline | When a computer is not connected to a host system or the Net, it is offline. |
| OLGA | The online Guitar Archive - Orinally an FTP site and later a Web site is a collection of guitar tablature for thousands of songs. It also contains lessons, chord charts, software, information on building guitars, and many links to other guitar-related Web sites. Unfortunatley, this Internet site, as well as it's many mirrors has been shutdown because of copyright infringement. The library of files on OLGA have been sent in by internet users since 1992. It developed out of the usenet newsgroups alt.guitar.tab and rec.music.makers.guitar.tablature. OLGA is provided free of charge and is run by volunteers. It is made available worldwide thanks to the generosity of these various mirrors. Most of the files in the archive will be found in the directories a- z and 1-9; they are organized according to the first letter/number of the band's name or artist's last name, but OLGA also contains a number specialised directories, dedicated to classical music, acoustic guitar, praise songs, country music and ChordPro formatted songs (the classical, acoustic, praise_songs, cowpie and chordpro directories, respectively.) |
