Study Notes
- Devices can connect to different networks in various ways, configurable in Windows' Network and Sharing Center
Connecting to Networks
- Windows offers customized, step-by-step wizards for different network types
- Connecting to the internet, setting up a new network, or connecting to a workplace are options
VPN Connections
- Connecting to a workplace involves setting up a dial-up or VPN connection
- Many organizations use a virtual private network (VPN) concentrator for secure remote access to private devices
- VPNs create an encrypted tunnel between a device and the VPN concentrator, securing data transmitted over the internet
- The VPN concentrator decrypts incoming data and encrypts outgoing data
- Organizations may use their own VPN software, or utilize the built-in Windows VPN client
Configuring VPN
- Configuration options include specifying the internet address of the concentrator and giving the connection a name
- Smart cards can provide added authentication for VPN connections with a card reader
- Connectivity to the VPN concentrator can be enabled or disabled via the network status icon on the Windows taskbar
Wireless Networks
- Wireless networks are widely used and Windows has a wizard to assist connections
- Configuration requires providing the network name (SSID)
- Specifying the security type (e.g., WPA2, WPA2 Enterprise), the encryption type, and the security key
Wired Ethernet
- Wired Ethernet connections are simpler, requiring only plugging in the cable
- Systems can connect to multiple network types simultaneously
- Windows prioritizes connections based on performance
Modifying Network Configuration
- Network configurations for wired and wireless networks can be modified by right-clicking the network adapter and selecting properties
- IPv4 information like IP address, subnet mask, and default gateway can be configured
- DHCP server use and alternate configurations can be specified
WWAN (Wireless Wide Area Network)
- WWAN allows connection to a cellular provider's network
- WWAN typically requires specialized hardware and sometimes an extra antenna can improve performance
- Wireless WAN access is possible via USB-connected adapters or 802.11 hotspots
- WWAN usually requires third-party software from the wireless provider for internet access where Ethernet or 802.11 networks are unavailable
