1 – Worth 4 points.
Using your Windows or Linux virtual machine in terminal mode ONLY:
Download the file located at:
http://users.cis.fiu.edu/~mrobi002/databases/RAMerrors2
Each record in this file represents the location of an error found in RAM.
Assume you have a computer with 8 gigs of RAM. Each gig in one RAM chip.
One Gigabyte contains 1,073,741,824 (2^30) bytes
———decimal————-
from bit to bit
RAM chip 0 contain addresses: 0 1,073,741,823
RAM chip 1 contain addresses: 1,073,741,824 2,147,483,647
RAM chip 2 contain addresses: 2,147,483,648 3,221,225,471
RAM chip 3 contain addresses: 3,221,225,472 4,294,967,295
RAM chip 4 contain addresses: 4,294,967,296 5,368,709,119
RAM chip 5 contain addresses: 5,368,709,120 6,442,450,943
RAM chip 6 contain addresses: 6,442,450,944 7,516,192,767
RAM chip 7 contain addresses: 7,516,192,768 8,589,934,591
Create a Java program to do the following:
– Open the text file you downloaded.
– Read each record.
– Print the RAM memory chip where each error is located as in the following
example: (the data below is not part of this program, it is just an example)

2 – Worth 1.5 points. Using Linux Shell Scripting.
– Implement division by 0, with error trapping, using if and while() commands,
How:
– Append your name, current date and time to a NEW file called results.txt
– Use a while loop.
– If the user enters the value -99 for the first or the second number, you must
exit the while loop immediately.
– Ask the user to enter the first number.
– Ask the user to enter the second number.
– If the second number is ZERO inform the user and ask for a correct second number.
– If the second number is NOT a zero, do the division, display all numbers in this
computation using labels, and add them to the results.txt file.
3 – Worth 1.5 points. Do the same as question 2 using Windows Batch.
4 – Worth 1.5 points. Linux Shell Scripting.
How:
– Use a for loop from 1 to 100.
– Find the results of calculating each number from (1 to 100 mod 5) + 2.
– After the for loop ends, display the average for all previous results and
append them to the results.txt file.
5 – Worth 1.5 points. Do the same as question 4 using Windows Batch.
Program submission
==================
You need to submit:
1 LastNameFirstInitialpgm3.java ex: RobinsonMpgm3.java
1 LastNameFirstInitialpgm3.sh ex: RobinsonMpgm3.sh
1 LastNameFirstInitialpgm3.bat ex: RobinsonMpgm3.bat
The Linux sh file will contain the divide by zero and the for loop parts
The Windows bat file will contain the divide by zero and the for loop parts
Make sure to rename the bat files to ba
Zip all three files into one file and email it (the zip file).
