All
about Linux - translated into Europeanese!
The operating systems can be to
have or they were abrieron. Mainframesysteme was in the majority
that it has, he pays attention proivoditelem of computers. In the
supplies of maykrosoft of zone PK their own systems Windows, mac of
the apple to the OS for their line of the computers of Macintosh
presented/displayed, and other some there elections. The known open
system was UNIX by itself, turned initially by the bell by the
laboratory, also, in the universities freely fixed. In his of the
linuxvariante it stops great PK, the works and OF IBM recently
universal selection of which they are present.
The software of a source of opening in the protected matters of the
reserved rights, but their gifts of the author leave outside towards
the advantage, frequently including the right to change it, when the
advantage is reduced by the new version. Linuks puts the free
software of foundation' it is protected; license GNU of the public
of „s, “as whole another software in extensive project GNU and this
protection does with the possible one to change to the user, Linuks,
also, them copies to even sell, when this right of the free
advantage in copies is preserved.
The consequence of the right of the free advantage that
mnogochislenn of NP the authors contributed the work Linuks to the
GNU and the main system of many valuable components added. Although
the quality control obrashchannyy dobrovets and surely foretells
that Linuks did not maintain commercial the use heavy, he, they are
which zamechateln successfully and seems of the best way in its UNIX
version of the way in the universal one and PK, that are used like
the operators of the Internet.
The diverse versions of the UNIX system; some, the majority to
teperteper noncommercially of used freely, at least have. All
kind-hearted of the delivery is graphical using interface. Although
mac would be in favor of its own OS, its version that used, OS x of
mac, was established in UNIX. In order to have systems like
Microsoft' Windows of 9$8$ s, 2000 and gives XP to the integrated
systems of high level. All the operating systems provide to the
maintenance the enumeration of the document, for example
nevertheless the system of maykrosoft could the same declaration of
the window for the enumeration as far as the advantage of the world
of the web browser. This integrated approach will form more with the
difficulty so that of nonproprietary of the advantage of the
capacities Windows of software, the characteristic, against which
Maykrosoft was cost in Antitrustprozessen.
the connection of the network.
The connection of the computer can happen by the wires, fiber
glasses or the transmissions of radio. The networks connected with
the wire can use the protected coaxial cable, that is so to the
wire, that it holds the television to the recorder of the video tape
or the antenna. With the modular pieces of connection can also use
more simply the installation of nezaslonennuyu, the shipment-offs of
the telephone are similar. The fiber glasses can put more signals
than they send-offs; they are more and more used greatly for the
more distances of dlinnikh frequently to connect the buildings with
Hochschulcampus or the place of the company of the aggregate and,
until the telephone companies refine their networks. The radio of
the microwave also takes the signals of the network of the computer,
generally like the part of the systems of dalniya of telephone.
Niederleistungsmikrowellenradio will be common for the radio
networks within the building.
Of inhausnetze.
Computers of the fixation of the building of the interior of
inhausnetze (LANs) or the small group in the composition of the
building. LAN, according to the indications of the illustration, is
possible in proportion with (1) the tire to collect, to which the
points of the front channel of zero or channel in structure subject
that extends, (2) to the ring secondly, in which each computer
subjects to friendly computer 2, to form the closed electrical
circuit, or (3) to the star, in which each computer is connected
immediately with the central computer and only indirectly with the
mutuum. Each of these has advantages, although the adjustment of the
tire got to be more generally.
Even if only 2 computers subject, must follow directories or the
minutes, are located in the connection. For example one could
indicate „is prepared, sent “and to hope that another one indicated
„that it prepares to him, to obtain. “If dividing the reticulada one
of many computers, was able minute the cover of the consideration of
„of the directory, later only if his return “, or „, later you do
not say, if somebody still speaks. “To the minutes is necessary also
to do I sketch k, to process the line of interference.
The most common LAN of the project under the form in fact of which
the center of 70 years of iger he was the tire connected the local
network, initiate initially with Xerox PARC. Each computer or
another instrument in the local network have the exceptional
direction of small piece 48. Each possible computer, that it wanted
would be to transfer, hears in the signal raise the motor, that
demonstrates that the transference he is constant. If it does not
determine, later it begins to transfer and it sends by the receiver
of the direction from the start of his transference. Each system in
the network obtains, each report nevertheless that did not pay
attention to, that they were not tried to him. Until the moment the
passages of the system, also hear, and if he determines simultaneous
transference, later it stops, waits for time at random and tries
again. The retardation at random before it tries again, diminishes
the probability that they enter conflict again. This project admits
like multiaccess of Kollisionserkennung (CSMA/CD). It acted very of
the best way, while the network is not loaded moderate heavy, and
after this one diminishes it, until the collisions are more
frequent.
