A time bomb virus is a virus that is triggered on a certain date. It is a malicious program that is designed to release virus unto a system. Once the time has arrived, it will automatically start working what it is programmed to do since any virus could do anything depending on what it is designed to do.
Answer:
Here is the script:
function dd = functionDMS(dd)
prompt= 'Enter angle in DD form ';
dd = input(prompt)
while (~checknum(dd))
if ~checknum(dd)
error('Enter valid input ');
end
dd = input(prompt)
end
degrees = int(dd)
minutes = int(dd - degrees)
seconds = ( dd - degrees - minutes / 60 ) * 3600
print degrees
print minutes
print seconds
print dd
Explanation:
The script prompts the user to enter an angle in decimal degree (DD) form. Next it stores that input in dd. The while loop condition checks that input is in valid form. If the input is not valid then it displays the message: Enter valid input. If the input is valid then the program converts the input dd into degrees, minutes and seconds form. In order to compute degrees the whole number part of input value dd is used. In order to compute the minutes, the value of degrees is subtracted from value of dd. The other way is to multiply remaining decimal by 60 and then use whole number part of the answer as minutes. In order to compute seconds subtract dd , degrees and minutes values and divide the answer by 60 and multiply the entire result with 3600. At the end the values of degrees minutes and seconds are printed. In MATLAB there is also a function used to convert decimal degrees to degrees minutes and seconds representation. This function is degrees2dms.
Another method to convert dd into dms is:
data = "Enter value of dd"
dd = input(data)
degrees = fix(dd);
minutes = dd - degrees;
seconds = (dd-degrees-minutes/60) *3600;

Answer: Detailed
Explanation:
SDLC consist of 7 phases. They are:
1. Planning.
2. System analysis and requirement
3. Design:
4. Coding:
5. Testing:
6. Installation
7. Maintenance
Here we are talking of the third phase. In this phase it is the design phase which consist of high and low level design. Here the preliminary design is included in high level design where it describes the required hardware, software, network capabilities and the modelling of the interface. However the detailed design in low level design will implement the coding and will finding of any errors in the implemented design as described by the preliminary design.
