Infrastructure refers to the fundamental physical and organizational structures, facilities, and systems needed for the operation of a society or enterprise. This can include everything from roads, bridges, and transportation systems to utilities like electricity, water, and telecommunications. In a broader sense, the term can also encompass social infrastructure like schools, hospitals, and emergency services. Infrastructure serves as the backbone of any developed society, enabling the efficient functioning of various sectors and improving the quality of life for its inhabitants. It is often funded through public investment and is crucial for economic development, as a well-maintained infrastructure can facilitate trade, support innovation, and provide employment opportunities. Due to its importance, the planning, development, and maintenance of infrastructure are often subjects of public policy and regulation.
