Answer: Switch
Explanation:
The switch is the device that is basically use for the connection for separate segment that basically appear in the similar segment in the computer network.
Switch is the ethernet that is based on the LAN peruses approaching TCP/IP information packets containing goal data as they go into at least one info ports. The goal data in the bundles is utilized to figure out which yield ports that will be utilized to sending the information on to its proposed goal.
Therefore, Switch is the correct options.
. If the sub-expression on the left of the __________ logical operator is true, the right
sub-expression is not checked.
Answer: "║"(OR) logical operator
Explanation: "ll" logical is used for defining the OR logical condition.This condition returns a value of true or false according to given expression.This expression can work on the Boolean variables only.
In this operator if any argument turn out to be true , the value returned is true otherwise the answer returned will be false.It also features that if the left side of this operator is true then the right sub-part of it's not evaluated as it becomes true overall.
Example of expression-> x ║ y ;
Prove the following theorems using truth table (a) X + XY = X (b) X + YZ = (X + Y)(X + Z)
Answer:
I attached you the answer in the picture
Explanation:
First, let's see the relationship between the logic gates and truth tables:
The operation of logic gates in relation to one another may be represented and analyzed using a branch of mathematics called Boolean Algebra which, like the common algebra, deals with manipulation of expressions to solve or simplify equations. Expressions used in Boolean Algebra are called, well, Boolean expressions.
AND Gate:
The AND gate is a logic gate that gives an output of '1' only when all of its inputs are '1'. Thus, its output is '0' whenever at least one of its inputs is '0'. Mathematically, A∧B = A · B.
OR Gate:
The OR gate is a logic gate that gives an output of '0' only when all of its inputs are '0'. Thus, its output is '1' whenever at least one of its inputs is '1'. Mathematically, A∨B = A + B.
Having this in mind, we just need to use basic Mathematical Logic operations
What is ‘White-Box’ testing?
Answer:
The white box testing is the method in which it basically test the internal structure and working application in the software testing.
In the white box testing the programming skills are require for designing the various test cases.
White box testing is also known as open box testing and it require the specific knowledge of the programming language for examine the particular software testing output.
Answer:
The White Box test is a software test in which the developer has access to the source code, knowing the internal structure of the product. Being analyzed and allowing the choice of specific parts of a component to be evaluated, allowing a precise search of the behavior of the structure.
The white box test levels are Unit Tests and Static Test.
what are somd negetive aspects and some positive aspects of having robots as a part of workplace?
Answer and Explanation:
Some of the negative aspects of robots at work place:
Lesser flexibilityHigher maintenance and installation costFuture insecurity and risk if the system malfunctionsA decline in the opportunities for humansUnemployment as a result of automation and robot regulated work place.Some of the positive aspects of robots at work place:
Higher accuracy Higher speeds More work in less timeProductivity and hence efficiency will increaseCost of some operations is reduced.Ease of employing in dangerous and hazardous fields by using specific robots for each task
