Answer: No
Explanation: Spread spectrum transmission is the wireless transmission technique for the wide channel that helps in decrement of the potential interference.The transmission of signal is based on the varying the frequency knowingly to achieve larger bandwidth.
The use of spread spectrum transmission in the WLAN(wireless local area network)is used for the regulatory purpose The regulation is the controlling of the area through policies.Thus,security is not the service that is provided to WLAN by spread spectrum transmission.
A is wrong because a folder can have any name.

Answer: star
Explanation: A star network topology is an implementation of a spoke–hub distribution paradigm in computer networks. In a star network, every host is connected to a central hub. In its simplest form, one central hub acts as a conduit to transmit messages. The star network is one of the most common computer network topologies.
Answer:
laser
Explanation:
These are well known printer types now. Let's review how they work to determine in which does heat plays a role.
inkjet: inkjet printers are printer throwing ink at the paper in the form of little drops. No heat involved here.
impact: That's the oldest technology, where a printing head is moving left and right to punch a printing ribbon and transfer ink onto the paper. No heat involved.
3D: 3D printers don't usually use paper... as they use other materials to create a 3D representation of a model. Heat is involved in the melting of the material before it's placed on the building model. But no paper involved here.
laser: laser printers are working very much like a photocopier machine... memorizing the pattern to be printed, then transferring it onto paper... using heat.
I think it's right.
