Answer:

It is true, that in a management information system, the quality of information is determined by its usefulness to users, and its usefulness determines the success of the information system.

Explanation:

A management information system (MIS) is a computerized and centralized database that collects data from many different resources in the organization. And, then processes and organized the data in a way that would be useful and helpful in making a business decision. These days, for both large and small organization, collection of data and use of technology are so prevalent and these organization collecting the data from their businesses resources daily even hourly such as daily sale, daily expense, hourly wages, etc, and then managing it in a way to make a right business decision. A good MIS in an organization gives a competitive advantage because it turns the data into usable and into helpful information that can be used in making business decisions and strategy and to increase profit.

However, the information quality is based on its usefulness to the user or to the organization. Because if the MIS produces the information that is not useful to the user, the information and use of MIS are useless in the organization because the information that is required in making a business decision is not useful.

If the MIS produces the quality information to its user in making the right business decision and organization or user take the right decision that brings profit to the organization.  Then, this use of information determines the success of an information system in an organization.

For example:

In a Bakery, the MIS produce the right information in making decision e.g. MIS produce information to bakery owner that on valentine day, most people buy chocolate. Then, the owner tries to meet the demand for chocolate on valentine's day. Therefore, this is the quality of information and it is determined by its usefulness to the bakery owner and its usefulness determines the success of MIS.

write a function named list_total that accepts a list as an argument (assume the list contains integers) and returns the cumulat
lutik1710 [3]

Answer:

def listSum(mylist):

  sum =0

  for item in range(0,len(mylist)):

      sum=sum+mylist[item]

  print(sum)

Explanation:

Using the Python programming language, I defined a function as listSum that accepts a list as a parameter and returns the sum of the elements in the list.

The most important logic here is defining the range of elements in the list not to exceed the length of the list using the len function. Then using a for statement, we loop through each element and add them up to a sum variable initially assigned the value of 0.

. Suppose: x = (1111 1111 1111 1111 1111 1111 1111 1100)2 y = (0011 1011 1001 1010 1000 1010 0000 0000)2 a. Is x bigger than y i
ahrayia [7]

Answer:

a. Using 32bit unsigned binary system, x is bigger than y

b. Using 32 bit signed system, x is not bigger than y.

Explanation:

a.

x = (1111 1111 1111 1111 1111 1111 1111 1100)2

y = (0011 1011 1001 1010 1000 1010 0000 0000)2

In an unsigned system all binary digits are used up as the magnitude bits;

First, we need to convert each number to decimal

x = 4294967292 (decimal)

y = 999983616 (decimal)

4294967292 is greater than 999983616

So, x is greater than y (in 32 bit unsigned binary system)

b.

x = (1111 1111 1111 1111 1111 1111 1111 1100)2

y = (0011 1011 1001 1010 1000 1010 0000 0000)2

In a signed system, the most significant bit is used as the signed bit, the remaining bits are used in representing the magnitude bits;

The most significant bit is always the first bit.

0 represents positive (+)

While

1 represents negative (-)

First we need to separate the most significant bit from the magnitude bits.

So x = 1 (111 1111 1111 1111 1111 1111 1111 1100)2

And y = 0 (011 1011 1001 1010 1000 1010 0000 0000)2

Then, we need to convert each number to decimal

x = -2147483644

y = +999983616

From the above, y is greater than x
