Answer:
A. Helps prevent a system from being fingerprinted by port scans.
B. Can restrict a computer from receiving network traffic.
D. Stop a process or application from launching.
Explanation:
The "host-based firewall" is an important type of<em> firewall software </em>that is being installed into a computer/device in order to allow it to control the network traffic. This enables the host to protect itself from any malware or viruses that may attack. It, primarily, provides a customized protection. Thus, it is more commonly used by <em>small businesses</em> or<em> individual people</em>.
Host-based firewalls allows "packet filtering." This controls the network access which makes it hard for attackers because of the little information that it provides. So, this explains option A. This then prevents a system from being fingerprinted by port scans.
Host-based firewalls can protect the device from unwanted network traffic, so this explains option B. This then restricts the computer from receiving the network traffic.
It can disable programs that are malicious, thereby stopping the launching of those programs. This explains option D.
Answer:
11001100 = 204
11111111 = 255
Explanation:
For 11001100:
1*2⁷ + 1*2⁶ + 0*2⁵ + 0*2⁴ + 1*2³ + 1*2² + 0*2¹ + 0*2⁰ = 204
Just replace 1's by 0's in the following calculation to do it for every 8 bit number:
1*2⁷ + 1*2⁶ + 1*2⁵ + 1*2⁴ + 1*2³ + 1*2² + 1*2¹ + 1*2⁰ = 255
If you don't want to do the calculation yourself, you can set the windows calculator in programmer mode, then select binary and key in the number.
