A crystalline solid held together by covalent bonds
Silicon dioxide (silica), the main ingredient in sand, is a network solid, also called a giant covalent lattice. Another example is diamond.
C in a diamond or SiO2 (quartz).

Network solid
Sand (SiO2) is a network covalent solid. It's considered to be extremely strong with relatively high melting points (>1550'C). It is made by atoms making multiple bonds with other atoms in the "network". To compare, another example of a network covalent solid is diamonds.
An example is the boron nitride. Another is silicon dioxide.
steel is the example of solid in solid
A grain of sand is a network solid (covalent network solid).
An example of a solid, is a rock.
network solid
Breaking covalent bonds throughout the solid would be required to melt a network solid.
It is a network solid, a lattice of many covalent bonds (like diamond, except that it is black rather than transparent).
