Computer manufacturing plays a significant role in the global economy and has numerous economic impacts on both local and global economies. Some of these impacts include:

1. Job Creation: Computer manufacturing creates employment opportunities for millions of people around the world. It stimulates both skilled and unskilled jobs in every stage of production, including research & development, designing, manufacturing, testing, sales, and support.

2. Economic growth: The computer manufacturing industry directly contributes to the economic growth of the countries where they are established. The computers and parts manufactured by factories drive demand, and through sales, the industry supports the local economy.

3. Exports: Computer manufacturing generates significant export revenue for countries that produce them, such as China, the United States, and Germany. Computer manufacturing is a significant contributor to their balance of trade.

4. Technological Innovation: The computer industry is known for its constant innovation, which attracts investment and contributes to the growth of the industry. This innovation spurs new technologies that create new business opportunities and the birth of new industries.

5. Environmental Impact: Like any industry, computer manufacturing has an environmental impact. On the one side, E-waste products generated through this sector threaten the environment. On the other hand, recycling E-waste products also generate employment opportunities for many people globally and generate significant revenue.

In conclusion, computer manufacturing has a significant contribution in terms of job creation, economic growth and technological advancement, and also, poses significant risks primarily because of improper disposal of e-waste products.
