Questions and Answers

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.

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.

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.

What role does ICANN play in the context of the Internet?

ICANN (Internet Corporation for Assigned Names and Numbers) coordinates the domain name system and facilitates the allocation of IP addresses globally. Signup and view all the answers

Explain the significance of TCP/IP in data transmission.

TCP/IP is a fundamental protocol suite that ensures reliable communication over the Internet by managing how data packets are transmitted and assembled. Signup and view all the answers

What is the primary difference between a LAN and a WAN?

A LAN (Local Area Network) covers a limited geographic area, while a WAN (Wide Area Network) spans large distances, connecting multiple LANs. Signup and view all the answers

How do fiber optics compare to twisted-pair cables in terms of data transmission?

Fiber optics provide higher bandwidth and faster data transmission speeds than twisted-pair cables, making them preferable for long-distance communication. Signup and view all the answers

Why might a small business choose a peer-to-peer network over a client-server architecture?

A small business may choose a peer-to-peer network due to its lower cost and simpler setup, making it more suitable for limited budgets and resources. Signup and view all the answers

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.
