Africa and De viris illustribus were partially inspired by Petrarch's visit to Rome in 1337. According to Bergin and Wilson (p. ix). It seems very likely that the inspirational vision of the Eternal City must have been the immediate spur to the design of the Africa and probably De viris illustribus as well. After returning from his grand tour, the first sections of Africa were written in the valley of Vaucluse. Petrarch recalls
The fact that he abandoned it early on is not entirely correct since it was far along when he received two invitations (from Rome and from Paris) in September 1340 each asking him to accept the crown as poet laureate. A preliminary form of the poem was completed in time for the laurel coronation April 8, 1341 (Easter Sunday).
Africa is 2009 Perpetuum Jazzile album. By large most successful song from the album is a capella version of Toto's "Africa", the performance video of which has received more than 15 million YouTube views since its publishing in May 2009 until September 2013.
Africa is a 1930 Walter Lantz cartoon short featuring Oswald the Lucky Rabbit.
Oswald was riding through the Egyptian desert on his camel. The camel, though looking real on the exterior, is actually mechanical because of the two ball-shaped pistons inside which Oswald manipulates with his feet like bike pedals. One day, a lion was running toward them. To defend himself, Oswald brought out a rifle but it malfunctioned. As a final resort, Oswald fired the ball pistons from the camel like a cannon and aimed into the lion's mouth. Terrified by its lumpy back, the lion runs away in panic.
Nearby where he is, Oswald saw an oasis and a palace. Upon seeing the apes dance and play instruments, the curious rabbit decides to join the fun. As he entered the palace, Oswald was greeted by the queen. The queen asked him who he is, and Oswald introduced himself in a song as well as giving advice for a possibly better lifestyle. Pleased by his visit, the queen asked Oswald if he would like to be her king. Oswald was at first uncertain, knowing he never met a queen, but immediately accepted. It turns out momentarily that the queen still has a king who shows up then throws Oswald out of the palace and into a pond full of crocodiles. Luckily, Oswald escapes unscathed and runs off into the desert.
Business services are a recognisable subset of Economic services, and share their characteristics. The essential difference is that Business are concerned about the building of Service Systems in order to deliver value to their customers and to act in the roles of Service Provider and Service Consumer.
The generic clear-cut, complete, concise and consistent definition of the service term reads as follows:
A service is a set of one time consumable and perishable benefits
delivered from the accountable service provider, mostly in close coaction with his internal and external service suppliers,
effectuated by distinct functions of technical systems and by distinct activities of individuals, respectively,
commissioned according to the needs of his service consumers by the service customer from the accountable service provider,
rendered individually to an authorized service consumer at his/her dedicated trigger,
and, finally, consumed and utilized by the triggering service consumer for executing his/her upcoming business activity or private activity.
A server is a computer program or a device that waits for requests from other devices or software (called "clients") and responds to them. A server typically processes data. The purpose of a server is to share data or resources among clients. The clients may run on the same computer or may connect to the server over a network. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Designating a computer as "server-class hardware" implies that it is more powerful and reliable than standard personal computers or is specialized for performing the server's role. Servers may be composed of large clusters of relatively simple, replaceable machines.
The use of the word server in computing comes from queuing theory, where it dates to the mid 20th century, being notably used in Kendall (1953) (along with "service"), the paper that introduced Kendall's notation. In earlier papers, such as the Erlang (1909), more concrete terms such as "[telephone] operators" are used.
