Originally, the World-Wide Web was designed as information medium for(71) research teams. A deliberately simple implementation model was chosen to make it as simple as possible for authors to(72) documents to the web, and to(73)these in the sense of updating content. This implementation model is centered around the notion of resources, usually file-based. For the (74)intended use of the web, resources presented a useful abstraction, as they related to relatively self-contained chunks of information such as research publications and (75) pages. Such chunks of information typically could be set up and maintained independently of other resources, so that resources were the appropriate abstraction for composition and modification.

● A glue that holds the whole Internet together is the network layer protocol,(71). Unlike most older network layer protocols, it was designed from the beginning with internetworking in mind. Its job is to provide a -(72) way to transport datagrams from source to destination, without regard to whether these machines are on the same network or whether there are other networks in between them.
Communication in the Internet works as follows. The (73)layer takes data streams and breaks them up into datagrams. Each datagram is transmitted through the Internet, possibly being fragmented into smaller units as it goes. When all the pieces finally get to the destination machine, they are reassembled by the
(74) layer into the original datagram. This datagram is then handed to the transport layer, which inserts it into the receiving process' input stream.
An IP datagram consists of a header part and a text part. The header has a (75) part and a variable length optional part.

Why is (1) fun? What delights may its practitioner expect as his reward? First is the sheer joy of making things. As the child delights in his mud pie, so the adult enjoys building things, especially things of his own design. Second is the pleasure of making things that are useful to other people. Third is the fascination of fashioning complex puzzle-like objects of interlocking moving parts and watching them work in subtle cycles, playing out the consequences of principles built in from the beginning. Fourth is the joy of always learning, which springs from the (2) nature of the task. In one way or another the problem is ever new, and its solver learns something: sometimes (3), sometimes theoretical, and sometimes both. Finally, there is the delight of working in such a tractable medium. The (4), like the poet, works only slightly removed from pure thought-stuff. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures.
Yet the program (5), unlike the poet's words, is real in the sense that it moves and works, producing visible outputs separate from the construct itself. It prints results, draws pictures, produces sounds, moves arms. Programming then is fun because it gratifies creative longings built deep within us and delights sensibilities we have in common with all men.
