Answer:
Correct answer is option (2) that is "return".
Explanation:
In any programming language, a variable name can be made up of letters (lower and upper case) and digits. we can also use "_" underscore character for declaring the variables but we cannot use any special character like “$”.We cannot use digits in the beginning of variables name. And we also cannot use reserved keywords of the language like "new","return","while" etc. There should not be space between the variable names. Options 1, 3 and 4 are not violating any of these properties. But in option (2), "return" is a reserved keyword. That is why it is not a valid variable name.
Some example of valid variables name:
foo
BAZ
Bar
_foo42
foo_bar
Some example of invalid variables name:
$foo ($ not allowed)
while ( keywords )
2foo (started with digit)
my foo (spaces )
Answer:
SO-DIMM DDR3
Explanation:
Based on the information provided within the question it can be said that the module that Jenny needs to order is known as SO-DIMM DDR3. This is the type of module that would work on her laptop computer. DDR3 is the most common generation of these RAM modules and SO-DIMM are rams that support 72, 100, 144, or 204 pins and is alot smaller than regular DIMM modules, coming in at about 3 inches.
Pattern recognition is used for similarities between concepts or problems in an algorithm.
What is meant by pattern recognition?
Pattern recognition is a data analysis method that uses machine learning algorithms to automatically recognize patterns and regularities in data. This data can be anything from text and images to sounds or other definable qualities. Pattern recognition systems can recognize familiar patterns quickly and accurately.
An example of pattern recognition is classification, which attempts to assign each input value to one of a given set of classes (for example, determine whether a given email is "spam" or "non-spam").
Therefore, Pattern recognition is used.
