Answer
Timekeeping has been a part of society since Ancient Egypt. The use of spring-powered mechanisms allowed clocks to be made smaller ... Essentially, the church bells and the mechanical clock now became the monitor of the working day.

Explanation:
In an educational setting, standards-based assessment is assessment that relies on the evaluation of student understanding with respect to agreed-upon standards, also known as "outcomes". The standards set the criteria for the successful demonstration of the understanding of a concept or skill -WIKIPEDIA

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.
Answer:
double x = 2.5;
double y = -1.5;
int m = 18;
int n = 4;
string s = "Storm";
string t = "Watch";
The output of the expression "x + n*y - (x+n)*y" is "6.25".
and the output of expression "m/n + m%n" is "6".
Explanation:
for the first expression,
x + n*y - (x+n)*y ,put value of every variables in it.
=2.5+4*(-1.5)-(2.5+4)*(-1.5)
=2.5-6.0-(6.5*(-1.5)
=-3.5+9.75
=6.25
for the second expression,
m/n + m%n, put value of every variables in it.
=18/4 +18%4
=4+2 ("/ will give quotient and % will give remainder")
=6
