Solution

Glycosidic linkage:
“The two monosaccharides are joined together by an oxide linkage formed by the loss of a water molecule. Such a linkage between two monosaccharide units through oxygen atom is called glycosidic linkage.”
Example of Glycosidic linkage:
Sucrose which on hydrolysis gives an equimolar mixture of $D - (+) - glucose$ and $D - (-) fructose$ .
These two monosaccharides are held together by a glycosidic linkage between $C_{1}$ of $α - D - glucose$ and $C_{2}$ of $β - D - fructose$ .
The formation of sucrose is shown below:
