Information Systems:

Information systems encompass the software, hardware, data, processes, and people that work together to manage and process information within an organization. These are integrated systems that manage and process information. They include databases, software applications, and hardware infrastructure that support data storage, retrieval, and manipulation. These systems can range from simple databases to complex enterprise resource planning (ERP) systems. Information systems are crucial for decision-making, data analysis, and overall business operations.

Satellite Communications:

Satellite communications involve the use of satellites to transmit signals over long distances. This technology is particularly valuable for global communication and broadcasting, as it enables coverage in remote areas and across oceans. Satellite communications support various services, including television broadcasting, internet connectivity, and navigation systems. This involves transmitting signals to and from satellites in orbit to facilitate long-distance communication. It's widely used for broadcasting, navigation (e.g., GPS), and remote sensing.
