Study Notes
Differences Between WAN and MAN
- WAN (Wide Area Network) covers large geographical areas, such as cities, countries, or continents, while MAN (Metropolitan Area Network) spans a smaller region, typically a single city or campus.
Tunneling in WANs
- Tunneling is used in WANs to encapsulate data packets within a secure tunnel, enabling safe transmission across public and private networks.
Leased Line in WANs
- A leased line is a private telecommunication line that provides dedicated bandwidth and consistent connectivity between two points in a WAN, typically used by organizations for reliable communication.
WiMAX in MANs
- WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband technology in MANs, offering high-speed internet access across a metropolitan area.
Connecting Multiple LANs in WAN
- Routers and gateways connect multiple Local Area Networks (LANs) within a WAN to facilitate data exchange and communication.
CAN in Computer Networks
- CAN (Campus Area Network) refers to a network that connects multiple LANs within a limited geographical area, such as a university campus.
Fault Tolerance in WAN
- WANs exhibit redundancy and diversity in their infrastructure, allowing for alternative data routing in case of failures, enhancing overall reliability.
Internet Speed in WAN
- Internet speeds in WANs can significantly vary based on the technology used, ranging from several Mbps to Gbps.
Propagation Delay in WAN
- WANs may experience higher propagation delays due to the distance involved in data transmission across large geographical areas.
Congestion Level in WAN
- WANs can experience congestion depending on the volume of data traffic and the capacity of the network infrastructure.
Ownership of WAN
- WANs can be owned by various entities, including private corporations, governments, telecommunications companies, and even multiple organizations collaborating.
Scope of WAN
- WANs provide extensive coverage and connectivity, interlinking numerous LANs, MANs, and other networks across vast distances.
Main Purpose of Tunneling in Networking
- Tunneling enables the secure transmission of data over potentially insecure networks by establishing an encrypted pathway.
Networks Securely Using VPN Connections
- WANs often use Virtual Private Network (VPN) connections to enhance security and privacy for data transmitted over public networks.
IPsec in VPNs
- IPsec (Internet Protocol Security) is a suite of protocols used to secure Internet Protocol (IP) communications, providing encryption and authentication for VPNs.
Difference Between Encrypted and Unencrypted Tunneling
- Encrypted tunneling connections safeguard data privacy through encryption, while unencrypted connections send data in plain text, making it vulnerable to interception.
Network Spanning Large Geographical Area
- The term for a network that spans a large geographical area, connecting multiple countries, is a WAN (Wide Area Network).
Advantages of VPN Connections Between WANs
- The primary advantage of using VPN connections between WANs includes enhanced security, protecting data from unauthorized access during transmission.
