Study Notes
Local Area Network (LAN)
- A LAN is a computer network that spans a small geographic area, typically within a building or campus
Network Segmentation
- Separating devices into different broadcast domains within a LAN can help improve network performance, security, and management
- Segmenting a network into smaller pieces contributes to network management by reducing network congestion, improving security, and enhancing troubleshooting
Drawbacks of Separate Switches
- Disadvantages of using separate switches for different broadcast domains within a LAN include increased cost, complexity, and network downtime
Inefficient Network Setup
- Inefficient network setups can lead to network congestion, security breaches, and management challenges
Purpose of Segmenting Devices
- The primary purpose of connecting devices to separate switches based on their required network access is to improve network security, performance, and management
VLAN Technology
- VLAN (Virtual Local Area Network) technology is used to virtually separate devices on the same physical switch into different networks
- VLANs allow for network segmentation without the need for separate physical switches
- The main advantage of using VLANs in a network is improved network management, security, and performance
Virtual Private Network (VPN)
- VPN stands for Virtual Private Network
- The primary purpose of a VPN is to securely connect devices over the internet
- A VPN concentrator is a device that manages VPN connections
- Routers and firewalls often integrate a VPN concentrator
- VLAN 1 typically represents the default VLAN on a switch
VPN Benefits
- Data is automatically encrypted when sent over a VPN connection
- The main purpose of using a VPN in a coffee shop is to secure internet connections
- When using a VPN, data and login credentials are automatically encrypted
