Answer:
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The term has been used in the computer industry at least since the early 1960s.
Answer:
Standard US Engineering Drawing Sizes
Drawing Size Dimensions (millimeters) Dimensions (inches)
ANSI C 431.8 x 558.8 17 x 22
ANSI D 558.8 x 863.6 22 x 34
ANSI E 863.6 x 1117.6 34 x 44
Explanation:
Technically it is not a a cell reference because it is not referring to a range of cells not just 1 sell the reference would be
Both logical AND and logical OR operators evaluate a given condition and return either true or false.
The logical AND operator returns true only when both the given conditions are evaluated to be true. For instance, c<em>ondition (10 > 5 AND 8 > 4) returns true because both the conditions with AND operator are true.</em> Now suppose the given condition is <em>(10 > 12 AND 8 > 4), it returns false because 10 is not greater than 12</em>. The AND operator returns true only when both the conditions are true; if any or both are false, false is returned.
The logical OR operator return true when either of the two conditions is true. For example, <em>the condition is (10 < 5 OR 8 > 4); it returns true because one condition is true which is 8 is greater than false</em>. It means the logical OR operator returns true if both or any of the given conditions are evaluated to be true. In case both the conditions are false in an OR statement then false is returned such as<em> (10 < 5 AND 8 < 4) returns false</em>.
