When we talk about building things, there are two main ways people do it: the old-fashioned way and the modern way.

Old-fashioned Building:

• Materials Used: People used clay, wood, and stones.
• Methods: They often had to do a lot of the work by hand, which took more time. This includes things like putting bricks together (masonry) or making wooden structures (carpentry).

Modern Building:

• Materials Used: Now, builders use stronger stuff like steel, glass, and concrete. These materials last longer and are very sturdy.
• Methods: Today, a lot of buildings are made using prefabrication and modular construction. This means parts of the building are made ahead of time and then put together quickly on site.

For example, when building a university building, they might use special concrete panels that are made in a factory. This makes it faster to put everything together than using traditional bricks.
