Mobile device management is a type of security software used by an IT department to monitor, manage, and secure employees' mobile devices (laptops, smartphones, tablets, etc.) that are deployed across multiple mobile service providers and across multiple mobile operating systems being used in the organization.
Answer:
A. DDoS Attacks
Explanation:
A zombie, in computer terminology, is a hacker, computer worm, trojan horse, or virus compromised internet connected computer, which can be remotely directed to perform malicious tasks
E-mail spams and denial-of-service, DoS attacks are spread and launched by botnets of zombie computers
Botnets which are also known as "zombie army", are used by hackers mainly for spam and distributed-denial-of-service, DDoS, attacks
While a DoS attack involves one machine, while a DDoS attack consist of multiple computing devices and machines
A botherder is the originator of a botnet and common botnets include Mr Black. Pushdo, and cyclone
The answer is 5.68 Volts.
So givens are electric supply of 30 VDC and the values of 3 resistors.
Given:
E= 30 VDC
R1 = 80 Ohms
R2 = 1000 Ohms
R3= 42000 Ohms
And what we are looking for is the voltage on the second resistor.
First we have to get the current of the circuit.
I = E/(R1+R2+R3)
I = 30 / (80+1000+4200)
I = 30 / (5280)
I = 0.00568 A
Then get the voltage V = I x R
V = 0.00568 x 1000
V = 5.68 V
