Answers

1. A network is a group of interconnected devices (such as computers, printers, and servers) that can communicate and share resources.
2. A LAN (Local Area Network) is a network that covers a small geographic area, while a WAN (Wide Area Network) covers a much larger geographic area.
3. The OSI (Open Systems Interconnection) model is a conceptual model used to describe and understand the communication functions of a network. It consists of seven layers, including the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer.
4. IP addresses (Internet Protocol addresses) are used to identify devices on a network and enable communication between them.
5. A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predefined security rules. Its purpose is to protect a network from unauthorized access and cyber attacks.
