Basic file organization technique"
before the computer, most information wis stored in paper form
when we needed information, we used to search through the papers
if we knew a date or category of the information we were
searching for, we would go to that section in the papers.
when we wanted to update or delete some data we searched
for it and modified them or struck them off. if the
data is limited, then all these tasks are easy. but imagine
libaray information, information about a student in a school, or
banking system data. how do we search for specific
required data in papers? it can be a never-ending task !
computers solve this problem, besearch the evolution
of file system data processing
discuss the evolution of file septem data processing and how it
is to understanding of the data access limitations that
databases atempt to overcome. also include your understanding
of data and information

As computers and other digital devices have become essential to business and commerce, they have also increasingly become a target for attacks. in order for a company or an individual to use a computing device with confidence, they must first be assured that the device is not compromised in any way and that all communications will be secure

Public static int mystery(int a[], int x) {     int c = 0;     for(int i = 0; i < a.length; i++) {        if (a[i] == x) c++;     } return c; }the method counts how many times an integer shows up in an integer array.the c variable is declared in the method to keep track of how many times the certain value has shown up.the for-loop loops through the entire array.the line    if (a[i] == x) c++;   checks if each element of the array is equal to the inputted integer to check. for each number in the array that is equal to the inputted integer x, the c variable will be incremented by 1. otherwise it will do nothing.then c is returned at the end of the loop.for example, if we have, in the main method with the mystery method coded in the class:     int arraytest[] = {2, 23, 23, 23, 3};     int testme = 23;     int count = mystery(arraytest, testme);     system.out.println(count); then the print out will be    3 because there are three 23s in that array.
