Key Characteristics of High-Speed Networks
1. Data Rate: High-speed networks typically offer data rates ranging from hundreds of megabits per second (Mbps) to several gigabits per second (Gbps).
2. Low Latency: These networks minimize delays in data transmission, which is crucial for real-time applications such as video conferencing and online gaming.
3. Scalability: High-speed networks can be easily scaled to accommodate growing data traffic and user demands without significant infrastructure changes.
4. Reliability: High-speed networks often include redundancy measures to ensure continuous service and minimize downtime.
Types of High-Speed Networks
High-speed networks can be categorized into several types, each serving different purposes and environments:
- Local Area Networks (LANs): Common in residential and office environments, LANs connect computers and devices within a limited geographical area.
- Wide Area Networks (WANs): Cover larger distances and connect multiple LANs, often using leased telecommunication lines.
- Metropolitan Area Networks (MANs): Span a city or a large campus, combining features of both LANs and WANs.
- Wireless Networks: Utilize radio waves to transmit data, offering mobility and convenience for users.
Technologies Enabling High-Speed Networks
