A USB-pluggable hardware true random number generator. In computing, a hardware random number generator (HRNG), true random number generator (TRNG), non-deterministic random bit generator (NRBG), [1] or physical random number generator [2] [3] is a device that generates random numbers from a physical process capable of producing entropy (in other words, the device always has access to a ...
The International Mobile Equipment Identity ( IMEI) [ 1] is a numeric identifier, usually unique, [ 2][ 3] for 3GPP and iDEN mobile phones, as well as some satellite phones. It is usually found printed inside the battery compartment of the phone but can also be displayed on-screen on most phones by entering the MMI Supplementary Service code ...

Calling codes in Europe. Telephone numbers in Europe are managed by the national telecommunications authorities of each country. Most country codes start with 3 and 4, but some countries that by the Copenhagen criteria are considered part of Europe have country codes starting on numbers most common outside of Europe (e.g. Faroe Islands of Denmark have a code starting on number 2, which is most ...
Worldwide distribution of country calling codes. Regions are coloured by first digit. Country calling codes, country dial-in codes, international subscriber dialing (ISD) codes, or most commonly, telephone country codes are telephone number prefixes for reaching telephone subscribers in foreign countries or areas via international telecommunication networks.
Mobile phone numbers are not uniquely different from land-line numbers, and thus follow the same rules for format and area code. Numbers may be ported between landline and mobile . The rarely used non-geographic area code 600 is an exception to this pattern (non-portable, and allows caller-pays-airtime satellite telephony ); some independent ...
The International Code of Signals was preceded by a variety of naval signals and private signals, most notably Marryat's Code, the most widely used code flags prior to 1857. What is now the International Code of Signals was drafted in 1855 by the British Board of Trade and published in 1857 as the Commercial Code. It came in two parts: the ...
The presentation of a telephone number with the plus sign indicates that the number should be dialed with an international calling prefix, in place of the plus sign. The number is presented starting the country calling code. This is called the globalized format of an E.164 number, and is defined in the Internet Engineering Task Force RFC 2806. [6]
