What is the primary distinction between wired and wireless networks?
What is the primary distinction between wired and wireless networks?
The primary distinction is that wired networks use physical cables for connections, while wireless networks utilize radio waves.
Describe a scenario where a peer-to-peer network might be more advantageous than a client-server network.
Describe a scenario where a peer-to-peer network might be more advantageous than a client-server network.
A peer-to-peer network is advantageous for small groups sharing files directly, as it simplifies resource sharing without the need for a centralized server.
Identify one advantage and one disadvantage of using a star topology.
Identify one advantage and one disadvantage of using a star topology.
An advantage of a star topology is that it allows easy addition of nodes, while a disadvantage is that if the central hub fails, the entire network goes down.

Study Notes
Computer Networks
- A computer network is a group of interconnected computers, using wired or wireless connections.
- Networks allow resource sharing, including data, printers, and applications.
- Networks are classified as wired or wireless based on their connection method.
Network Types and Topologies
- Network types include LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network), and PAN (Personal Area Network).
- Each network type serves different geographic scales.
- Common network topologies include star, bus, and ring topologies, each with unique advantages and use cases.
Network Architectures
- Client-server networks have a central server that manages resources.
- Peer-to-peer networks distribute resources among all connected nodes.
- Peer-to-peer networks are simpler and less expensive but have reduced security.
Transmission Media and Protocols
- Data transmission happens over various media: twisted-pair cables, fiber optics, and wireless technologies.
- Protocols like TCP/IP, HTTP, and FTP ensure efficient, secure communication.
Internet and WWW
- The Internet connects millions of computers globally, managed by organizations like ICANN.
- The World Wide Web (WWW) enables multimedia interactions.
- HTML and web browsers allow website navigation and creation.
