In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the CSMA/CA protocol for a second frame

at step 2, rather than at step 1. What rationale might the designers of CSMA/CA have had in mind by having such a station not transmit the second frame immediately (if the channel is sensed idle?

Answer:

There could be a collision if a hidden node problem occurs.

Explanation:

CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.

If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.

1. Why is it important to evaluate the website on which you plan to shop? (1 point)
UkoKoshka [18]
Hi there!

For #1 the answer is the site may not be trustworthy, and you risk identity theft. If you are not sure a site legit then don't trust it. Some sites can easy to tell if they can be trusted by the amount of detail put into the site itself, but others are not so easy to tell. In general, if a site does not have https:// in the web address, but instead has just http:// (no "s" in it) then don't trust it.

For #2 the answer is to use<span> a secure browser. If the browser you are using is insecure then the info you put into a site can be compromised and stolen by the browser itself because it reads all info put on it.

For #3 the answer is i</span><span>t has a secure payment page. Again going back to the https:// vs. the http:// if the page that you pay on is not secured then your credit card info can be stolen when put in because the site without a secured page will allow others with access to see your info.
