Answer:
<u>vecCont.capacity()</u> returns the maximum number of elements that can be inserted into the vector container vecCont without reallocation.
Explanation:
Consider the provided information.
vecCont.capacity() is a function that returns the maximum number of elements(without reallocation) that can be inserted into the container.
<u>vecCont.capacity()</u> returns the maximum number of elements that can be inserted into the vector container vecCont without reallocation.
Answer:
First we understand what is hash function.A hash function is mostly used in Hashmaps. It maps different keys to a set of values.There may occur a case when we have same key but different values.This case is called collision.So we have to use different collision handling techniques that are open addressing and separate chaining.
A perfect hash function maps key-value pair such that there are no collisions.

Answer: combine, control, and route audio signals from inputs to outputs
Explanation:
A audio mixer is refered to as the sound mixer or the mixing console and it's an electronic device that's used for mixing, and combining several audio signals and sounds.
The input to the console is the microphone. The audio mixer can also be used in controlling digital or analog signals. These are then summed up in producing output signals.
Therefore, the function of the audio mixer is to combine, control, and route audio signals from inputs to outputs.
Answer:
a) Viruses
Explanation:
Vulnerability assessment is performed by variety of tools and these can be protocol analyzer, vulnerability scanner, Honeypots, port scanners, honey nets and banner grabbing tools.
Port scanners : they are used to scan the ports which can be exploited by attackers. Most of TCP/IP applications communicate using different ports and attackers can exploit these ports if they are found vulnerable. for example : ports like 80 and 443 are commonly used for HTTP and SSL communication. 22 is used for SSH and if they are open to world then it will allow attackers to use those to get the entry into the system.
Protocol Analyzers : They are used to analyze the packet captures. tools like wireshark, tshark, these tools will help user to decode HTTP/SSL/HTTPS/FTP/RSTP or any application protocols communication. this will help user to understand any unwanted or non-anticipated traffic.
Vulnerability Scanners : They are used to detect the vulnerabilities in the network or systems. these will help administrators to get the alerts whenever there are unanticipated activity. It will have two types of scanners one is active scanner and other is passive scanner. Active scanners will keep on sending probes at the fixed time slots and passibe scanners will be in listening mode all the time. These scanners will alert when a new nodes comes up or goes down or if any system gets compromised.
Honeypots and Honey nets : They are devices or softwares which are having limited security. These devices are made vulnerable purposefully so that attackers can try and attack. This will help softwares to detect the attackers when they try to exploit these open vulnerabilities. They are deceptions created with purpose.
Banner grabbing Tools : These are tools which will capture the banner information like HTTP protocol version, underlying operating system, open ssl versions being used, server software and similar information. these are important as it will open up potential vulnerabilities in the underlying software. for ex : SSLv3 has a vulnerability known to world and can be exploited by anyone.
