Answer:
C. ground antennas
Explanation:
AKA Satellite Dishes That Communicate Just Like Direct Tv dish It is focused by a bowl-shaped parabolic dish onto a device in the center called a "feed horn", which channels the signal to a "low-noise block down converter" (LNB) which filters out unwanted interference, and sometimes converts it to yet another frequency before amplifying it and sending it to the satellite receiver
Answer:
4. A Denial of Service attack (DDOS attack).
Explanation:
A DDOS attack is a malicious attempt to disrupt the normal traffic to a service.
In essence, it sends an enormous amount of requests to the service, until the server is overwhelmed because it can't handle that much traffic, and collapses in an overflow.
Thus, regular users are not able to access their services.
Usually, attackers use a botnet, a network of "zombie" computers that have been previously infected with a malware that allows the attacker to remotely control them, then the botnet starts to send a flood of traffic from different locations, and make the attacker difficult to detect or track.
You could get a laptop for like 200 that could run well and enough space for stuff.
I’d say both techies are correct.
Volatility, as applied in gasoline, is quantified by the tendency of the liquid to change to vapor at any given temperature (vaporize). This rate of change might be hard or easy, this depends on the temperature or the pressure. Technician B is also correct. RVP is defined and determined experimentally according to the ratio of the vapor volume to the liquid volume at 100 °F.
