Answer:
beacon frame
Explanation:
Beacon frame is a management frame In computer networks, known to be in IEEE 802.11 based WLANs. These frames are transmitted periodically and they contain all the information a station will require before it can rightly transmit a frame.
When it comes to announcing the presence of devices in a wireless computer network (WLAN), Beacon frames are used, and they can also be used in the synchronization of the devices and services
Explanation:
The special case that exists in linked list when we are managing them is when we are dealing with the first element of the list.
When we create a linked list we create a first node separately.
If we delete or add element in front of the first element we have to carefully handle that case.
Hence the special case is when we are dealing with the first element of the list.
The answer is IPS (Intrusion Prevention Systems)
The Intrusion Prevention Systems and Intrusion Detection Systems (IDS) are two security technologies that secure networks and are very similar in how they work. The IDS detects unauthorized user activities, attacks, and network compromises, and also alerts. The IPS, on the other hand, as mentioned, is very similar to the IDS, except that in addition to detecting and alerting, it can also takes action to prevent breaches.
Answer:
Interference of signal and the range between the user and the access point.
Explanation:
Elevators, specifically those with high voltage, are notoriously known for being a source of very strong magnetic fields. They produce a lot of harmonics that causes signal interference and noise. Whenever there is any kind of noise in a network, it causes huge intermittent connection. Also, the farther away the user is from the router or the AP, the weaker the signals and the more the intermittencies. The user is recommended to be within the edges if the range limit.
