     Proposition: A statement which is true or false, easy for people to read but hard to manipulate using logical equivalences

     WFF: An accurate logical statement which is true or false, there should be an official rigorus definition in your textbook. There are 4 rules they must follow. Harder for humans to read but much more precise and easier to manipulate

     Example:

     • Proposition : All men are mortal
     • WFF: Let P be the set of people, M(x) denote x is a man and S(x)denote x is mortal Then for all x in P M(x) -> S(x)

   • What is the difference between Algorithm and Logic?

     Wow your question took me on a voyage and I found something!! This may not stand as an answer but putting it here as a reference.

     Algorithm = Logic + Control

     An algorithm can be regarded as consisting of a logic component, which specifies the knowledge to be used in solving problems, and a control componentwhich determines the problem-solving strategies by means of which that knowledge is used.

     The logic component determines the meaning of the algorithm whereas the control component only affects its effeciency. The effeciency of an algorithm can often be improved by improving the control component without changing the logic of the algorithm.

   • What is the difference between output and output logic in Verilog?

     Top Answer

     Answered Oct 01, 2018 · 2 votes

     logic keyword was introduced in system verilog. It avoids the confusion between a reg and wire.

     input a;output reg x; //x is declared as a registeralways@(posedge clk) x <= a;

     Another way of writing above block

     input a;output logic x; //Here x is taken as a register since its used inside always blockalways@(posedge clk)x <= a;input a;output logic x;assign x = a; //Here x is taken as a wire due to assign statement

   • What is the difference between a business object and business logic

     Top Answer

     Answered May 23, 2017 · 3 votes

     http://en.wikipedia.org/wiki/Business_object

     Business Object: A type of an intelligible entity being an actor inside the business layer in an n-layered architecture of object-oriented computer programs. Whereas a program may implement classes, which typically end in objects managing or executing behaviors, a business object usually does nothing itself but holds a set of instance variables or properties, also known as attributes, and associations with other business objects, weaving a map of objects representing the business relationships.

     http://en.wikipedia.org/wiki/Business_logic_layer

     Business Logic Layer : A business logic layer (BLL), also known as the domain layer, is a software engineering practice of compartmentalizing. Within a BLL objects can further be partitioned into business processes (business activities) and business entities. Business process objects typically implement the controller pattern, i.e. they contain no data elements but have methods that orchestrate interaction among business entities.

     So basically a business object models an entity (usually a real world object such as Employee or Account) whereas business logic facilitates the interaction between business objects and between other application layers.

     I think the most appropriate answer was given by Daniel Hilgarth. His answer was don't separate the business logic from its objects, because this leads to an anemic domain model.

     While I think the following WPF MVVM solution structure proposed by Paul S Patterson is a good one I don't think it's appropriate for everyone.

     http://www.paulspatterson.com/technology/dot-net-development/mvvm-and-wpf-for-vb-net-series-2-part-1-again/

     The creation of distinct Business Logic and Business Object projects probably works best if your business objects are Data Transfer Objects (DTOs) e.g. Linq to SQL rather than a more complex object such as a composite that may have tighter coupling to the business logic.

   • What is the difference in logic and performance between LOCK XCHG and MOV+MFENCE?

     Top Answer

     Answered Jan 05, 2019 · -1 votes

     The difference is in purpose of usage.

     MFENCE (or SFENCE or LFENCE) is useful when we are locking a part of memory region accessible from two or more threads. When we atomically set the lock for this memory region we can after that use all non-atomic instruction, because there are faster. But we must call SFANCE (or MFENCE) one instruction before unlocking the memory region to ensure that locked memory is visible correctly to all other threads.

     If we are changing only a single memory aligned variable, then we are using atomic instructions like LOCK XCHG so no lock of memory region is needed.

   What is a Proposition?A proposition is the basic building block of logic. It is defined as a declarative sentence that is either True or False, but not both. The Truth Valueof a proposition is True(denoted as T) if it is a true statement, and False(denoted as F) if it is a false statement. For Example, 1. The sun rises in the East and sets in the W...

   Since we need to know the truth value of a proposition in all possible scenarios, we consider all the possible combinations of the propositions which are joined together by Logical Connectives to form the given compound proposition. This compilation of all possible scenarios in a tabular format is called a truth table. Most Common Logical Connectiv...

   What is a connective in logic?

   • Connectives can be used to connect logical formulas. For instance in the syntax of propositional logic, the binary connective can be used to join the two atomic formulas and , rendering the complex formula . Common connectives include negation, disjunction, conjunction, implication, and equivalence.

   Does Frege's system represent classical propositional logic?

   • Frege’s system is in two senses adequate for representing classical propositional logic: Because the pair \ (\ {\neg, \supset\}\) is truth-functionally complete, any formula expressible with any combination of bivalent truth-functional connectives whatsoever can be translated into a formula in Frege’s system.

   May 18, 2023 · Propositional Logic. First published Thu May 18, 2023. Propositional logic is the study of the meanings of, and the inferential relationships that hold among, sentences based on the role that a specific class of logical operators called the propositional connectives have in determining those sentences’ truth or assertability conditions.

   Simplified programs may also run faster, since they require fewer operations. In hardware, simplifying expressions can decrease the number of logic gates on a chip because digital circuits can be described by logical formulas (see Problems 3.5 and 3.6). Minimizing the logical formulas corresponds to reducing the number of gates in the circuit.
