Answer:
In Windows 7, there are four default libraries: Documents, Music, Pictures, and Videos. All the default libraries include two standard folders: the user folder specific to each library and the public folder specific to it.
Explanation:
Answer:
To avoid collision of transmitting frames.
Explanation:
CSMA/CA, carrier sense multiple access is a media access control protocol of wireless networks that allows for exclusive transmission of frames and avoidance of collision in the network. When a frame is not being sent, nodes listening for an idle channel gets their chance. It sends a request to send (RTS) message to the access point. If the request is granted, the access point sends a clear to send (CTS) message to the node, then the node can transmit its frame.
Many nodes on a wireless network are listening to transmit frames, when a frame is transmitting, the node has to wait for the access point to finish transmitting, so it sends a RTS message again to exclusively transmit a second frame.
Most email clients contain a "subject" that allows the user to read an email message without actually opening it.
Answer:
Option c: Heuristic
Explanation:
Heuristic scanning is a form of computer virus detection analysis that screen for the suspicious characteristic of the program which maybe a virus. Heuristic scanning is designed to detect those new computer virus, unknown virus or the modified version of the known virus.
To perform heuristic scanning, a weigh-based evaluation algorithm will be adopted to estimate the likelihood of the current scanned program behaves like a virus which can pose a computer threat. If it exceeds a threshold level, an alarm will be triggered.
