The PowerBook G3 is a line of laptop Macintosh computers produced by Apple Computer between 1997 and 2001. It was the first laptop to use the PowerPC G3 (PPC740/750) series of microprocessors. It was succeeded by the Titanium PowerBook G4 line in 2001, which used the PowerPC G4 (PPC74xx) series of microprocessors.
PowerBook G3 (Kanga)
The first Macintosh PowerBook G3, code-named "Kanga," was introduced in November 1997. At the time of its introduction, the PowerBook G3 was advertised as the fastest notebook computer available (a title formerly held by its predecessor, the 240MHz PPC-603ev-based PowerBook 3400c). This model was based on the PowerBook 3400c, and was unofficially known as the PowerBook 3500. It used the same case as the 3400c, and a very similar motherboard. The motherboard was upclocked from 40MHz to 50MHz, resulting in some incompatibility with older 3400 RAM modules. Other changes to the motherboard included doubling the on-board RAM from 16 MB to 32 MB, and a faster version of the on-board Chips and Technologies graphics controller. The G3 made the Kanga more than twice as fast as a 3400c, and the improved graphics controller allowed it to refresh the screen 74 percent faster.
In computer networking, a reliable protocol provides reliability properties with respect to the delivery of data to the intended recipient(s), as opposed to an unreliable protocol, which does not provide notifications to the sender as to the delivery of transmitted data. The term "reliable" is a synonym for assured, which is the term used by the ITU and ATM Forum in the context of the ATM Service-Specific Coordination Function, for example for transparent assured delivery with AAL5.
Reliable protocols typically incur more overhead than unreliable protocols, and as a result, function more slowly and with less scalability. This often is not an issue for unicast protocols, but it may become a problem for reliable multicast protocols.
TCP, the main protocol used on the Internet, is a reliable unicast protocol. UDP, often used in computer games or in other situations where speed is an issue and the loss of a little data is not as important because of the transitory nature of the data, is an unreliable protocol.
John Wesley believed that all Christians have a faith which implies an assurance of God's forgiving love, and that one would feel that assurance, or the "witness of the Spirit". This understanding is grounded in Paul's affirmation, "...ye have received the Spirit of adoption, whereby we cry Abba, Father. The same Spirit beareth witness with our spirits, that we are the children of God..." (Romans 8:15-16, Wesley's translation). This experience was mirrored for Wesley in his Aldersgate experience wherein he "knew" he was loved by God and that his sins were forgiven.
