Answer:
D
Explanation:
The answer is D because if you're looking for lightweight materials, you'll be dealing with chemistry, and chemistry is sience.
Answer:
a) 255
b) 61602
c)
d)
Explanation:
You need to understand the decimal equivalent of hexadecimal numbers, <em>from 0 to 9 numbers are represented the same way, from 10 to 15 we use the alphabet, meaning 10 equals A in hexadecimal base, 11-B, 12-C, 13-D, 14-E, and 15-F.</em>
For your first exercise you'll enumerate the number's positions fromright to lef begining with 0:
a. F F
position 1 0
Now you'll multiply your hexadecimal number (using the decimal equivalent for your letters) for the base (16) elevated to the number of the position:
Finally, you'll add your results:
240+15=255
FF=255
b. F 0 A 2
position 3 2 1 0
F0A2=61602
c. F 1 0 0
position 3 2 1 0
0F100=61696
d. 1 0 0
position 2 1 0
100=256
I hope you find this information useful! Good luck!
Answer: (D) Distributed denial- of- service (DDoS)
Explanation:
The distributed denial of service attack is one of the type of attack that occur when the multiple system are basically flooded with the resources and the bandwidth.
- Botnet is one of the example of DDoS as it caused the DOS (denial of service) for the users.
- This type of attack is more substantial as compared to the DoS attack as they use the multiple system for attack the single target simultaneously.
Therefore, Option (D) is correct.
You'll need a helper variable for this, so depending on your programming language, the solution becomes:
int helper;
helper = arr[i];
arr[i] = arr[j];
arr[j] = helper;
Explanation:
Windows Firewall
Windows Firewall is a packet filter and stateful host-based firewall that allows or blocks network traffic according to the configuration. A packet filter protects the computer by using an access control list (ACL), which specifies which packets are allowed through the firewall based on IP address and protocol (specifically the port number). A stateful firewall monitors the state of active connections and uses the information gained to determine which network packets are allowed through the firewall. Typically, if the user starts communicating with an outside computer, it remembers the conversation and allows the appropriate packets back in. If an outside computer tries to start communicating with a computer protected by a stateful firewall, those packets are dropped automatically unless access was granted by the ACL.
