Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which network has the strongest security?
A
LAN
B
WAN
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -LANs are certainly more secure, less costly and easier to maintain, but only a WAN traverses multiple geographical areas. LANs can still cover larger areas than a single building, but never as large as WANs.

Detailed explanation-2: -A LAN is a private network which makes it quite secure and reliable for use in companies and businesses. It can hold off any outside interference with the network. A LAN can operate at a comparatively higher level than other kinds of wide area networks.

Detailed explanation-3: -LAN supports significantly faster data transfer than WAN In comparison, WAN is significantly slower (approximately 150 Mbps) due to several reasons: There is a loss in speed as data packets travel through a long distance. Internet service providers (ISPs) typically cap the maximum speed in publicly owned WAN.

Detailed explanation-4: -An Ethernet connection is much more secure than a WiFi connection. Data on an Ethernet network can only be accessed by physically attaching a device to the network, while data on a WiFi network travels through the air and can be more easily intercepted.
