Answer:

A perimeter intrusion detection system (PIDS) is a device or sensor that detects the presence of an intruder attempting to breach the physical perimeter of a property, building, or other secured area.

the use of buried sensor for perimeter intrusion detection system, becomes very popular due to the advantage of been a discreet or even an invisible detection system and avoiding the need to build an above-the-ground fence to protect the perimeter due to costs or environmental reasons

Explanation:

<em>Description of 3 systems:</em>

Barrier-Mounted :Fence Intrusion Detection System

PIDS deployed on or in conjunction with a fence or other physical barrier (e.g. DAS cable or other motion sensors mounted on a fence).

Ground-based or Below-ground :

PIDS deployed below ground (again a DAS cable can be used or pressure sensitive cable or electromagnetic field). These do not require a physical barrier.

Free-Standing

PIDS deployed above ground that do not need to be installed on or in conjunction with a physical barrier (e.g. bistatic microwave link).

Example of one PIDS system I have seen deployed in a familiar location is the ones at the prison which is a barrier mounted or some inairports that prevent small to cause harm to small animals.

After 4th collision in ethernet, find the maximum time that the adapter waits until sensing the channel again for a 100 mbps bro
VARVARA [1.3K]

Waiting time for a 100 Mbps broadcast channel is 0.512 ms

Recall that with the CSMA/CD protocol, the adapter waits K * 512 bit times after a collision,

where K is drawn randomly. For K = 100,

The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms

The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms

Waiting time for a 10 Mbps broadcast channel is K*512*0.0001= 5.12 ms

Waiting time for a 100 Mbps broadcast channel is K*512*0.00001= 0.512 ms

<h3>What is a collision in Ethernet?</h3>
  • A collision happens on a half-duplex Ethernet network when two devices on the same network attempt to communicate data at the exact same time.
  • The two transmitted packets are "collapsed" by the network, which results in the network discarding both of them.
  • On Ethernets, collisions are unavoidable.
  • A collision is a momentary interaction between two bodies or more than two bodies at once that modifies the motion of the bodies involved as a result of the internal forces at work.
  • Collisions entail the application of force (there is a change in velocity).
