Dual band phones tend to work in the UK and Europe and most of the world (GSM 1800 and GSM 900), whilst in America you need a phone that can take GSM 1900 so most often a Tri band or Quad band phone is the best option.

Tri band refers to the physical frequencies which your mobile phone can operate on. The three international frequencies ranges or bands reserved for GSM are 900MHz, 1800MHz and 1900MHz. In Australia, as at the time of publication, most GSM networks still use only the 900MHz frequency band. Soon, GSM carriers will be upgrading their networks to support the 1800MHz band also.

These terms define the working frequencies of GSM cellular phones on particular networks. There are 3 working frequencies - 900/1800/1900. GSM phones that work on 2 frequencies are called dual band while those that work on 3 frequencies are called tri-band. This facility allows the user to use his/her cell on different networks, and beneficial for international roaming. See similar questions...

A tri-band phone operates at three supported frequencies, such as 900/1800/1900 MHz or 850/1800/1900 MHz. A dual-band phone operates at two frequencies, such as 850/1900 MHz or 900/1800 MHz. See similar questions...

Oi! means "hey" and came from a greeting term among the working class of England in the late '60s and soon became our style of music, since it represents the white working class. One of the most legendary bands is Skrewdriver founded by Ian Stuart, the grandfather of all skinheads. By a tragic twist of fate, he died in '93, but his music lives on now & forever and can be pretty much be found anywhere they sell WP CD's & tapes. See similar questions...

For the programs that select students on the basis of ENTER alone, a two stage process of selection occurs: The selection officer for the program looks at all of the applicants and identifies applicant whose ENTER indicates that they are 'Clearly-in'. These applicants are selected. Next, they identify those whose ENTER clearly indicates they are 'not of a suitable standard'. They are 'Clearly-out'. Between these groups is another group of applicants neither clearly-in nor clearly-out. See similar questions...

This refers to Mirage’s deployment model: not physically in-line. Despite this out-of-band connection, its behavioral algorithms allow Mirage NAC to function as effectively as in-line threat mitigation devices. By deploying out-of-band, Mirage NAC installs and configures easily without complicated network reconfigurations and without introducing a risk of latency or failure in the network.

The Bands are two groups of countries based loosely on GNI per capita (World Bank figures). Institutions in countries with GNI per capita below $1000 (OARE Band 1) are eligible for free access. OARE will launch Band 2, providing low cost access to institutions in Band 2 countries, by 2008. See similar questions...

The band's stage area requirements vary, depending on the type of event and the size of band you request. We do realize that some venues are not able to provide a great deal of area. We work within the available space provided. If the event is a large ballroom, usually the stage is 16' deep by 24' to 30' wide. Prior to your parties' arrival, most large equipment (lights, music stands, speakers, and so forth) is usually set up. See similar questions...

Well apparently it has to do with something called gene expression, which refers to the pattern in which genes are switched on and off. And gene expression has a major effect on your body's biological processes. Each cell in your body contains a 'power-factory' that produces energy, called the mitochondria. See similar questions...
