In fact, IEEE 802 splits the OSI Data Link Layer into two sub-layers named Logical Link Control ( LLC ) and Media Access Control ( MAC ), so that the layers can be listed like this:

Logical controls ( also called technical controls ) use software and data to monitor and control access to information and computing systems.

It defines Logical Link Control ( LLC ), which is the upper portion of the data link layer of the OSI Model.

* At the Data Link Layer: The IEEE 802. 2 protocol at the Logical Link Control sublayer of the data link layer may provide both connectionless and connection-oriented services.

* Logical data model

* Logical schema: describes the semantics, as represented by a particular data manipulation technology.

Boolean operators are a subclass of logical operators ( Logical operators are binary operators that manipulate data at the bit level .).

Logical topologies are bound to network protocols and describe how data is moved across the network.

Logical block addressing ( LBA ) is a common scheme used for specifying the location of blocks of data stored on computer storage devices, generally secondary storage systems such as hard disks.

To satisfy the data modeling enhancement requirements that were identified in the IISS-6202 project, a sub-contractor, DACOM, obtained a license to the Logical Database Design Technique ( LDDT ) and its supporting software ( ADAM ).

LVM tools will allow implementation of data striping in conjunction with mirroring ; however, LVM1 will not allow adding additional disks to a striped Logical Volume ( LV ).

Rule 9: Logical data independence:

Logical data independence is more difficult to achieve than physical data independence.

Though some engineers programmed PAL devices by manually editing files containing the binary fuse pattern data, most opted to design their logic using a hardware description language ( HDL ) such as Data I / O's ABEL, Logical Devices ' CUPL, or MMI's PALASM.

; Logical data modeling

The NDIS forms the Logical Link Control ( LLC ) sublayer, which is the upper sublayer of the OSI data link layer ( layer 2 ).

* Logical volume management, a method of transparently storing computer data spread over several partitions

* IEEE 1284. 4-2000: Data Delivery and Logical Channels for IEEE 1284 Interfaces-allows a device to carry on multiple, concurrent exchanges of data

Logical data models represent the abstract structure of a domain of information.

Logical data models should be based on the structures identified in a preceding conceptual data model, since this describes the semantics of the information context, which the logical model should also reflect.

Logical and physical data models are very different in their objectives, goals and content.

Some years after the 1900-1901 publication of his main work, the Logische Untersuchungen ( Logical Investigations ), Husserl made some key conceptual elaborations which led him to assert that in order to study the structure of consciousness, one would have to distinguish between the act of consciousness and the phenomena at which it is directed ( the objects as intended ).

The problem of free will is especially salient now with Logical Determinism: how can choices be free, given that propositions about the future already have a truth value in the present ( i. e. it is already determined as either true or false )?

An illustration of some important differences between " analytic " and " continental " styles of philosophy can be found in Rudolf Carnap's " Elimination of Metaphysics through Logical Analysis of Language " ( Originally published in 1932 as " Überwindung der Metaphysik durch Logische Analyse der Sprache "), a paper some observers have described as particularly polemical.

The Compatibilist will often hold both Causal Determinism ( all effects have causes ) and Logical Determinism ( the future is already determined ) to be true.

Windows 2000 and later do not use, they have the Logical Disk Manager feature, as well as DiskPart.

Logical names do not have a close equivalent in POSIX operating systems.

Some have drawn comparisons to the dispute resulting in the creation of Lojban, wherein Loglan creator James Cooke Brown attempted to assert copyright over the language, a claim contested by the creators of Lojban, the Logical Language Group.

Multiple host operating systems have been modified to run as guest OSes on Sun's Logical Domains Hypervisor.

She is the first female to have climbed the grade 9a / 5. 14d ( Bain de Sang in 2002 and Logical Progression ).

Other protocols that have announced their intention to use WiMedia's UWB radio platform include Bluetooth and the WiMedia Logical Link Control Protocol.

Some years after the publication of the Logical Investigations, Husserl made some key elaborations that led him to the distinction between the act of consciousness ( noesis ) and the phenomena at which it is directed ( the noemata ).

Apart from a host of bugfixes, V4. 1 added some new features, including Sidechaining, Free Group Routing, Project Logical Editor, and Recording from Sum Objects.

* Logical schema: describes the structure of some domain of information.

* Logical shift right, an operator used in some computer languages

Logical Unit Number Masking or LUN masking is an authorization process that makes a Logical Unit Number available to some hosts and unavailable to other hosts.

Logical formulas are discrete structures, as are proofs, which form finite trees or, more generally, directed acyclic graph structures ( with each inference step combining one or more premise branches to give a single conclusion ).

* Supervisory format PDUs, or S-format PDUs, with a 16-bit control field, which are intended to be used for supervisory functions at the LLC ( Logical Link Control ) layer.

His time at the University of Chicago resulted in four essays collectively entitled Thought and its Subject-Matter, which was published with collected works from his colleagues at Chicago under the collective title Studies in Logical Theory ( 1903 ).

Logical positivism, in the formal sense, began from discussions of a group known as the First Vienna Circle which gathered during the earliest years of the 20th century in Vienna at the Café Central.

In 1896, theologian J. H. Worman identified seven categories of pantheism: Mechanical or materialistic ( God the mechanical unity of existence ); Ontological ( abstract unity, Spinoza ); Dynamic ; Psychical ( God is the soul of the world ); Ethical ( God is the universal moral order, Johann Gottlieb Fichte ); Logical ( Hegel ); and Pure ( absorption of God into nature, which Worman equates with atheism ).

* The Logical framework approach, which is popular in international development organizations.

In " The Elimination of Metaphysics Through Logical Analysis of Language " ( 1932 ), Rudolf Carnap accused Heidegger of offering an " illusory " ontology, criticizing him for committing the fallacy of reification and for wrongly dismissing the logical treatment of language which, according to Carnap, can only lead to writing " nonsensical pseudo-propositions.

# Logical blocks 0 and 1 of the volume are the Boot Blocks, which contain system startup information.

# Logical block 3 is the starting block of the Volume Bitmap, which keeps track of which allocation blocks are in use and which are free.

Initially, two additional levels of representation were introduced ( LF — Logical Form, and PF — Phonetic Form ), and then in the 1990s Chomsky sketched out a new program of research known as Minimalism, in which Deep Structure and Surface Structure no longer featured and PF and LF remained as the only levels of representation.

< li > 會意 / 会意 huìyì: Logical aggregates, in which two or more parts are used for their meaning.

* Data Management, consisting of supervisor support for Physical IOCS, and macros for Logical IOCS which could be incorporated into the user's processing programs.

IBM produced PC DOS 7. 10 which was based on PC DOS 2000 and added support for Logical Block Addressing ( LBA ) and FAT32 partitions.

Logical analysis shows that there are two different kinds of statements ; one kind includes statements reducible to simpler statements about the empirically given ; the other kind includes statements which cannot be reduced to statements about experience and thus they are devoid of meaning.

In Logical progressive chess ( by Paul Byway, Variant Chess 18, automne 1995 ) there's no castling or pawn two advance ( hence no en-passant capture ) since these rules were added to speed up the game, which is not relevant in progressive form.

Logical positivism, a movement begun as a small circle which grew around the philosopher Moritz Schlick in Vienna, inspired many philosophers in the English speaking world from the 1930s through the 1950s.

They start with physical volumes ( PVs ), which can be either hard disks, hard disk partitions, or Logical Unit Numbers ( LUNs ) of an external storage device.
