Answer:
1. Clients and servers—how services such as e-mail and web pages connect using networks.
2. IP addresses—how devices on a network can be found.
3. Network hubs, switches and cables—the hardware building blocks of any network.
4. Routers and firewalls—how to organize and control the flow of traffic on a network.
Answer:
B) computeValue(10);
Explanation:
Given
Header: void computeValue(int value)
Required
Determine the valid call
To call a function from another function or from the main, the following syntax has to be used.
<em>function-name(parameter-1, parameter-2, parameter-3,.....,parameter-n);</em>
<em />
In the function header given:, the following can be observed:
- The function name is computeValue
- It has only one parameter and it is of type integer
So, to call the function; we make use of computeValue(10);
Where 10 represents the value of the parameter (i.e. argument)
Attackers frequently use ACK scans to circumvent a firewall or other filtering tools. During a NULL scan, all packet flags are enabled. The most recent versions of Nessus Server and Client are compatible with Windows, Mac OS X, FreeBSD, and the vast majority of Linux variants.
<h3>What is ack scan ?</h3>
- ACK scans are used to identify hosts or ports that have been blocked or are resistant to other types of scanning. An attacker uses TCP ACK segments to learn about firewall or ACL configuration.
- Attackers probe our router or send unsolicited SYN, ACK, and FIN requests to specific UDP/TCP ports.
- TCP ACK Scan sends an ACK message to the target port to determine whether or not it is filtered.
- On unfiltered ports, a RST reply packet will be sent for both open and closed ports. Filtered ports will either generate no response or generate an ICMP reply packet with an unreachable destination.
- The TCP ACK scanning technique attempts to determine whether a port is filtered by using packets with the ACK flag set.

Independent Component Analysis (ICA) is based on information-theory and is also one of the most widely used dimensionality reduction techniques.
When a computer restarts without a hardware power-down-power-up cycle, it is doing an update.
