Study Notes
Networking Overview
- Global connectivity empowers collaboration and community through the "human network."
- Advances in networking have transformed communication and connectivity over the last two decades.
- The Internet fosters a boundary-less world and encourages the formation of global communities.
Network Components
- Networks can range from simple connections (e.g., two computers) to complex global structures.
- Three main categories of network components are Devices, Media, and Services.
- End Devices: Originate or receive messages, marking the start and end points of data flow.
- Intermediary Devices: Include switches, routers, and firewalls; manage data flow, regenerate signals, and notify about errors.
Network Media
- Data travels through various media which facilitate communication from sources to destinations.
Quality of Service (QoS)
- Network Bandwidth: Maximum data-carrying capacity, measured in bits per second (bps).
- Network Speed: Rate at which data is transmitted.
- Network Throughput: Actual successful data transfer over time.
- Network congestion can degrade performance, leading to packet loss and delayed connections.
Emerging Trends in Networking
- Bring Your Own Device (BYOD): Empowers users to utilize personal devices for work, enhancing flexibility with laptops, tablets, and smartphones.
- Online Collaboration: Tools like Cisco WebEx facilitate real-time teamwork and are essential in business and education.
- Video Communication: Cisco TelePresence enables effective remote collaboration, increasing productivity.
- Cloud Computing: Allows storage and backup of data on online servers, promoting ease of access.
Network Security
- Critical for protecting data and ensuring services in networks of all sizes.
- Requires implementation of various protocols, technologies, and techniques to defend against threats.
- External Threats: Include viruses, spyware, hacker attacks, and data interception.
- Internal Threats: Often caused by users; BYOD policies can increase vulnerabilities within corporate data.
