Detailed explanation-1: -Unlike relative references, absolute references do not change when copied or filled. You can use an absolute reference to keep a row and/or column constant. An absolute reference is designated in a formula by the addition of a dollar sign ($) before the column and row.

Detailed explanation-2: -An absolute cell reference in a spreadsheet application is absolute, which means that they remain consistent regardless of the size or shape of the spreadsheet or if the reference is copied or moved to another cell or sheet. For spreadsheets that contain constant values, absolute cell references are essential.

Detailed explanation-3: -If you want to maintain the original cell reference when you copy it, you “lock” it by putting a dollar sign ($) before the cell and column references. For example, when you copy the formula =$A$2+$B$2 from C2 to D2, the formula stays exactly the same. This is an absolute reference.

Detailed explanation-4: -There are two types of cell references: relative and absolute. Relative and absolute references behave differently when copied and filled to other cells. Relative references change when a formula is copied to another cell. Absolute references, on the other hand, remain constant no matter where they are copied.
