A range check is often used when a person works with data consisting of numbers, dates and times, or currency, ensuring that a number is within a specific range.

Explanation:

Range checks allow a person to set suitable boundaries.
In microsoft (example) : Accept letters (a - z) only : Is Null OR Not Like "*[!a-z]*" : Any character outside the range A to Z is rejected. (Case insensitive.)
An example of a range check is checking to see if the value of a 16-bit integer is within the capacity of a 16-bit integer. When a range check is performed, upper and lower boundaries are specified.
Range check is a validation check which can be applied to numeric fields. This is done to ensure that only numbers within a certain domain can be entered into a field. Remember that this does not necessarily mean that the data entered will be correct. But it will certainly lie within reasonable limits.
A method of validation which checks that data falls between an upper and lower acceptable value.

When a linked chain contains nodes that reference both the next node and the previous node, it is called a(n)?

Nuetrik [128]

Doubly linked chain

When a linked chain contains nodes that reference both the next node and the previous node, it is called a doubly linked chain. This type of chain is often used in data structures because it provides a way to easily traverse the data in both directions. However, because each node must reference both the next node and the previous node, doubly linked chains require more memory than singly linked chains.
