Wide Area Network (Lesson 4) Flashcards
is a telecommunications network that extends over a large geographical area, typically spanning cities, states, countries, or even continents.
Wide Area Network (WAN)
Key Components of WAN (4):
- Transmission Lines
- Networking Devices
- Protocols and Standards
- Point of Presence (POP)
WANs utilize various transmission media to transmit data over long distances. These include fiberoptic cables, microwave links, satellite connections, and even traditional copper wires.
Transmission Lines
WANs incorporate a variety of networking devices such as routers, switches, and modems to facilitate data transmission and manage network traffic efficiently.
Networking Device
WANs rely on standardized protocols and technologies for communication between devices
Protocols and Standards
are key locations within a WAN infrastructure where multiple telecommunication carriers and network connections converge.
Point of Presence (POP)
Characteristic of WAN (4)
- Geographical Coverage
- High Bandwidth
- Public and Private Networks
- Reliability
Types of WAN Connections (4)
- Leased Lines
- Virtual Private Networks
- MPLS Networks
- Satellite Links
WANs cover large geographical areas, often spanning across multiple cities, states, or countries.
Geographical Coverage
WANs typically offer higher bandwidth compared to LANs to accommodate the long-distance data transmission requirements.
High Bandwidth
WANs can be implemented using both public and private network infrastructures.
Public and Private Networks
WANs are designed with redundancy and failover mechanisms to ensure high reliability and uptime.
Reliability
provide dedicated point-to-point connections between two locations, offering consistent bandwidth and reliability.
Leased Lines
utilize private networks such as the internet to establish secure connections between remote locations.
Virtual Private Networks (VPN)
networks offer efficient routing and traffic management capabilities, making them suitable for large-scale WAN deployments.
MPLS Networks (Multiprotocol Label Switching)
