Which are more secure, wired or wireless networks? Explain.
Wired networks are always more secure because they're not advertising themselves to the world; e.g. you need to have physical access to connect to a wired network. Wireless networks can be secure; but the fact of the matter is they're advertised to any passer-by and are susceptible to having their keys cracked.
Leaving aside ways to attack a network that wired and wireless networks are equally vulnerable to: Wired networks can be protected with physical security (i.e. people generally have to break into a building to get access to a wireless network). Wireless networks can only be protected with encryption (although a properly configured one will have all the traffic encrypted, whereas that isn't the case with a typical wired network). So, generally speaking, wired networks are more secure.
