Describe Satellite network connections
Satellites can provide signals to cover many hundreds or even thousands of miles, including vast oceans, depending on their orbit pattern. However, the further from earth their orbit, the more they suffer from delay. They can also be disrupted by interference from weather and solar radiation.
The term ‘Cable Modem’ is best describing by …
A device that demodulates broadband frequencies into digital baseband signals
Which of the following is not a network category based on the geographic dispersion of network components?
- Campus-area network (CAN)
- World-area network (WAN)
- Metropolitan-area network (MAN)
- Personal-area network (PAN)
- Local-area network (LAN)
World-area network (WAN)
What is the most popular topology that is used on modern LANs?
Star topology has been the most popular for over two decades
Which two of the following network categories is NOT constrained by cable distance limitations?
PAN
LAN
WLAN
CAN
PAN -personal area network
WLAN-wireless local area network
It interconnects network components within a building
Local area network (LAN)
It interconnects network components that are geographically dispersed between two or more locations.
Wide-area network (WAN)
It interconnects locations scattered throughout a city
Metropolitan-area network (MAN)
A network scaled smaller than a LAN. An example might be a connection between a smartphone and a headset.
Personal area network PAN
Bus topology
single cable to which devices are connected too

single point failure
What is Network Virtualization?
Network Virtualization refers to the use of virtualized memory to create a network service that mimics what might have been a local only device.
When interconnecting multiple geographically dispersed sites with WAN links to a central site, what is this topology referred to as?
Hub and spoke topology
What IoT wireless technology is specifically useful with personal area networks (PAN) and other short distance connections?
Bluetooth — has strictly local limitations.
When creating multiple operating systems within a virtual server, the hypervisor can provide each of them with its own IP Address by the creation of a ____
vNic
A vNic is a virtual network interface card, which is actually an additional instance of the NIC diver installed and mapped to the Virtual Machine that is using it. While the vNic can be part of a vSwitch, vRouter, or VLAN, those are not required for it to function.
