Connectivity Flashcards
(13 cards)
What does connectivity mean in networking?
Connectivity refers to the ability of computers and devices to communicate and share resources over a network, either locally (LAN) or across long distances (WAN).
What are the main types of network connectivity?
- Wired connectivity (e.g., Ethernet, fiber optics)
- Wireless connectivity (e.g., Wi-Fi, cellular, Bluetooth)
What is the role of routers in network connectivity?
Routers connect multiple networks together and route data between them, such as connecting a home network to the internet.
What is the role of switches in network connectivity?
Switches connect devices within a local area network (LAN) and forward data to the correct destination using MAC addresses.
How do access points contribute to connectivity?
Access points extend wireless network coverage by acting as a bridge between wired and wireless devices, allowing Wi-Fi-enabled devices to connect to the network.
What is bandwidth and how does it affect connectivity?
Bandwidth is the maximum rate of data transfer across a network connection. Higher bandwidth allows for faster data transmission and better connectivity performance.
What is latency in network connectivity?
Latency is the delay between sending and receiving data over a network. Low latency is crucial for real-time applications like video calls and gaming.
What is the difference between LAN and WAN in terms of connectivity?
LAN (Local Area Network) covers a small area like a home or office, while WAN (Wide Area Network) spans large geographic areas and connects multiple LANs, often using the internet.
How do ISPs support connectivity?
Internet Service Providers (ISPs) offer access to the internet and may provide additional services like email, web hosting, and DNS resolution, enabling global network connectivity.
What is a VPN and how does it affect connectivity?
A VPN (Virtual Private Network) creates a secure, encrypted tunnel between a device and a server over the internet, allowing private and safe connectivity even over public networks.
What is redundancy in network connectivity?
Redundancy involves having multiple paths or systems in place to ensure continued network access even if one connection or device fails, improving reliability.
What are some common connectivity issues users face?
Common issues include signal interference, IP conflicts, hardware failures, configuration errors, and bandwidth limitations.
