General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and 3G cellular communication system's global system for mobile communications (GSM). GPRS was originally standardized by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP).
GPRS usage is typically charged based on volume of data. This contrasts with circuit switching data, which is typically billed per minute of connection time, regardless of whether or not the user transfers data during that period.
GPRS data is typically supplied either as part of a bundle (e.g., 5 GB per month for a fixed fee) or on a pay-as-you-use basis. Usage above the bundle cap is either charged per megabyte or disallowed. The pay-as-you-use charging is typically per megabyte of traffic.
GPRS is a best-effort service, implying variable throughput and latency that depend on the number of other users sharing the service concurrently, as opposed to circuit switching, where a certain quality of service (QoS) is guaranteed during the connection. In 2G systems, GPRS provides data rates of 56–114 kbit/second.2G cellular technology combined with GPRS is sometimes described as 2.5G, that is, a technology between the second (2G) and third (3G) generations of mobile telephony. It provides moderate-speed data transfer, by using unused time division multiple access (TDMA) channels in, for example, the GSM system. GPRS is integrated into GSM Release 97 and newer releases.
Green are the rashes, O;
Green are the rashes, O;
The sweetest hours that e'er I spend,
Are spent among the lasses, O.
There's nought but care on ev'ry han',
In every hour that passes, O:
What signifies the life o' man,
In hands of lasses, O.
The war'ly race may riches chase,
An' riches still may fly them, O;
An' tho' at last they catch them fast,
Their hearts cannot enjoy them, O.
But give me cannie hour at night,
My arms about my dearie, O,
An' war'ly cares an' war'ly men
May a' gae tapsalteerie, O!
For you sae douce, ye sneer at this;
Ye're nought but senseless asses, O;
The wisest man the warl' e'er saw,
