Answer:

Timer devices is the important application in the embedded system. It basically maintain the timing of the operation which synchronize the external clock in the timer device.

Timer device is the special type of clock that is use to measure the fixed time interval in the embedded system.

Timer devices used in many applications like measure the time delay and used in generating the baud rate.

The main function of the timer device in the embedded system is that it counts from the zero upward in the stopwatch for measuring the time elapse.

Answer:

In the context of cyber security, social engineering (SE) is a deceptive practice that exploits human weaknesses by inducing victims to interact with a digital device in a way that is not in their best interest. Many of these attacks begin with spam , which is defined as unsolicited messages that are usually sent in massive numbers using electronic mail systems. A spam filter uses a set of rules to examine email messages and determine which are spam. There are four common types of spam filters. Content filters examine the content within a message for certain words or phrases commonly used in spam emails. Header filters review the email header for falsified information, such as spoofed IP addresses. Blacklist filters block mail that originates from IP addresses of known spammers. Permission  filters block or allow mail based on the sender's address. Phishing is an email scam that masquerades as a message from a(n) legitimate company or agency of authority, such as the IRS. Pharming redirects Web site traffic to fraudulent Web sites that distribute malware, collect personal data, sell counterfeit products, and perpetrate other scams. A rogue antivirus exploit usually begins with a virus warning and an offer to disinfect the infected device. Some software is not exactly malware, but it is a nuisance. A PUA takes up residence on a digital device and seems impossible to disable or remove.

Answer: The answers to all parts of this question are based on "automatic string". The condition is also provided which states that the string the machine outputs is the same string (4-digit string) which is fed to the machine as input.

Explanation: (a) The string will not remain automatic string if it contains a digit greater or equal to $5$. As we know that machine should print the same string which is fed into it. In this case the machine will insert a 0 in place of $5$. So the number is inserting a 0 when it is output by the counting machine. For example if we input $2152$ machine will print "$0120$" which shows that the digits are not the same as fed to the machine. If we take string $0702,$ which is given in the question, we see that machine prints out "$2010$" which means that number is inserting a 0 so automatic string cannot contain a digit greater than $5$

(b) The same answer as given in (a). For example the if we write $4220$ machine prints out "$1020$". So the automatic string cannot contain $4.$

(c) This is a bit tricky as machine count the digit $3$. Lets take an example string $3303$. the machine prints out "$1003$". It counts three BUT its not an automatic string because the string printed out is different from the string that was fed to the machine. So automatic string cannot contain $3.$

(d) Now we know that an automatic string cannot contain digits 3,4,5 and above. So it can contain digits 0,1 and 2 with 0 at the end as the automatic string cannot contain digit 3 or above.Lets take a few examples of strings with combinations of 0,1 and 2 to check if they are automatic strings.

$1220$ the machine prints $1120$ which is not the same as fed into machine so its not an automatic string.
$2020$ the machine prints out "$2020$". Its 2 times "$0$", 0 times "$1$",2 times "$2$" and 0 times "$3$" which is the same as fed to machine so $2020$ is an automatic string.
$1210$ is an automatic string as the machine prints out "$1210$" which is the same string fed to machine.
