What collision detection system is used in wireless networks?
actually in wireless networks, collision detection does not work. The radio is a half-duplex channel, so it can not send and detect for the collision at the same time. Moreover the the sender can't necessarily hear what receiver is receiving, so it can't tell if collision has occurred. Instead CSMA with collision avoidance is used. So, the sender only sends when it senses the channel is free and reserves the channel by sending RTS and CTS to avoid collisions.
Why do wireless Ethernet networks attract hackers?
Wireless networks are wireless so they flout in the air, like radio waves. Then a hacker can hook on and gain access.
Are current wireless Ethernet networks in the US are based on the IEEE 8023 standard?
no
How many different types of wireless networks are?
Wifi, Internet(wireless), Ethernet(wireless), Mifi (sounds funny but it really is a network.)
Why are wireless ethernet networks more challenging to set up than wired networks?
Mostly because of security issues and EMI.

What device connects networks?
A device with wireless connectivity or Ethernet ports, which otherwise connects a series of devices in a network topology.
Are Wireless networks faster than other network types?
No, wireless networks tend to be slower than wired networks but they offer more range and you don't need a whole lot of wires. Wireless routers normally have Ethernet ports so you can have a mix of wired and wireless if you desire. The speed difference between the two is barely noticeable, well that's my opinion.
What is a wireless sensor?
A Wireless sensor network, according to UbiBot, is a collection of devices that can exchange data gathered from a monitored field using wireless networks. The data is routed across numerous nodes and connects to other networks via a gateway, such as wireless Ethernet.
Each computer that is part of a network must have what?
Every computer that is connected to a local area network or LAN should have an Ethernet card. For wireless networks, computers should have a wireless adapter.
Which are two types of nic's?
Ethernet NIC: A network interface card (NIC) designed to connect a device to an Ethernet network using an RJ45 port. Wireless NIC: A network interface card (NIC) equipped with wireless capabilities to connect a device to Wi-Fi networks.
What does the company WiFi Networks provide?
The WiFi Networks company provides wireless internet access to mobile devices. The company allows for one to connect to the internet without the use of wires and ethernet cords.
