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.
This type of infection is this a characteristic of a computer worm
For better understanding, lets explain what computer Worms means.
- Computer Worm are commonly referred to as an independent program that often replicates or double itself by copying a fraction of itself onto another computer. They often exit in two forms. They are:
- Network Worm is a type of computer worm that replicates or copies different fraction of itself to computers linked together in known network.
- Host Worm is a type of computer worm that replicates or copies itself to another computer in a network and later on remove or deletes itself completely from the previous computer in which it was in.
- Computer worm are capable of replicating themselves without human intervention.

Answer:
The benefits of relying on System Development Standards is explained below.
Explanation:
There are many benefits of having a Well Defined Systems Development. It helps in having a pre - planned and well defined structure before the project starts. It helps in having a Clear view of the whole project and also each phase of the whole System Development. It helps in having an understanding of cost required and the revenues generated at each phase of the whole system development. It helps in having an understanding of the goal of each phase and procedures need to be followed for that particular goal. It also helps in having the quality checked and the improvements need to be made for the desired quality.
