Key Topics Covered

1. The Role of Telecommunications in Business

• Definition: Telecommunications involve the electronic transmission of data over distances.
• Business Applications:
  • Facilitate communication between employees, customers, and suppliers.
  • Support collaboration through tools like video conferencing and instant messaging.
  • Enable e-commerce, supply chain management, and data sharing.
• Impact: Telecommunications improve productivity, decision-making, and global reach.

2. Components of a Telecommunications Network

A telecommunications system consists of:

• Clients and Servers: Devices that request and deliver services (e.g., PCs, smartphones).
• Network Interfaces: Hardware like modems or network adapters.
• Connections: Communication channels, such as fiber optics, copper wires, or wireless signals.
• Switching Devices: Routers and switches that direct data through the network.
• Software: Network operating systems and protocols for data management and communication.

3. Types of Networks

• Local Area Networks (LANs): Connect devices within a limited area (e.g., a building or campus).
• Wide Area Networks (WANs): Span large geographic areas, connecting multiple LANs.
• Metropolitan Area Networks (MANs): Cover cities or regions, bridging the gap between LANs and WANs.
