Network Types Flashcards
Q: What is a Wide Area Network (WAN)?
A: A WAN, commonly referred to as the Internet, is a large network made up of many LANs. Large companies or government agencies may have an internal WAN, also called an Intranet.
Q: What is a Local Area Network (LAN)?
A: A LAN is an internal network, typically used in homes or offices, that assigns local IP addresses (e.g., 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
Q: What is a Wireless Local Area Network (WLAN)?
A: A WLAN is similar to a LAN but provides wireless connectivity, allowing devices to connect without cables.
Q: What is a Virtual Private Network (VPN)?
A: A VPN connects multiple network sites to one LAN, making users feel as if they are directly connected to a different network.
Q: What is a Site-to-Site VPN?
A: A Site-to-Site VPN connects entire network ranges between two network devices, typically used to link company networks over the Internet.
Q: What is a Remote Access VPN?
A: A Remote Access VPN creates a virtual interface on a client’s computer, making it behave as if it’s on a remote network.
Q: What is an SSL VPN?
A: An SSL VPN is done within a web browser, streaming applications or entire desktop sessions to the browser, becoming increasingly common.
Q: What is a Global Area Network (GAN)?
A: A GAN is a global network, like the Internet, but can also be private networks spanning multiple WANs and connecting computers worldwide.
Q: What is a Metropolitan Area Network (MAN)?
A: A MAN is a regional network that connects several LANs, typically using high-performance connections for high data throughput.
Q: What is a Wireless Personal Area Network (WPAN)?
A: A WPAN is a personal network using Bluetooth or Wireless USB, usually covering only a few meters, often used in IoT applications.
Q: What infrastructure do GANs use?
A: GANs use the glass fibers infrastructure of wide-area networks, interconnecting them by international undersea cables or satellite transmission.
Q: What connects the branches in a MAN?
A: MANs use high-performance routers and glass fiber connections, often provided by international network operators, to connect branches.
Q: What is a Piconet?
A: A Piconet is a WPAN established via Bluetooth, typically extending only a few meters, suitable for short-range communication.
Q: How are WPANs used in IoT?
A: WPANs in IoT communicate control and monitor applications with low data rates, using protocols like Insteon, Z-Wave, and ZigBee.
Q: How can you identify a WAN?
A: A WAN is identified by using a WAN-specific routing protocol like BGP and IP schemas not within RFC 1918 ranges.
