What are the key goal, performance, and risk indicators?
Answer:
KRIs are a way to quantify and monitor the biggest risks an organisation (or activity) is exposed to. By measuring the risks and their potential impact on business performance, organisations are able to create early warning systems that allow them to monitor, manage and mitigate key risks.
Effective KRIs help to:
Identify the biggest risks. Quantify those risks and their impact. Put risks into perspective by providing comparisons and benchmarks. Enable regular risk reporting and risk monitoring. Alert key people in advance of risks unfolding. Help people to manage and mitigate risks.While KPIs help organisations understand how well they are doing in relation to their strategic plans, KRIs help them understand the risks involved and the likelihood of not delivering good outcomes in the future.
A _____ is used by a host to forward IP packets that have destination addresses outside of the local subnet.
Ip packets are forwarded using the default gateway that is being used by the host.
Explanation:
Ip packets are forwarded using the default gateway that is being used by the host, where it has placed their destination addresses on the outside of the local subnet. The default router is another representation of the default gateway. It is also known as the default router. The computer sends the packets to the default router when it wishes to send to any other subnet. In-network this device is being a point of access to the other networks.
Many organizations have policies that require users to: a. retain their passwords for a minimum of 30 days. b. include at least three consecutive letters of part of their name in their passwords. c. change their passwords on a regular basis. d. share their passwords with the administrator.
Answer:
Explanation:
Answer is C. Change their passwords on a regular basis.
Many organizations have policies that require users to retain passwords, include their name in passwords, change passwords regularly, and not share passwords with administrators.
Explanation:Many organizations have policies that require users to:
Retain their passwords for a minimum of 30 days.Include at least three consecutive letters of part of their name in their passwords.Change their passwords on a regular basis.Do not share their passwords with the administrator.These password policies are aimed at enhancing security and reducing the risk of unauthorized access to sensitive information. By enforcing password retention, organizations ensure that users regularly update their passwords, which makes it harder for hackers to guess or crack them. Additionally, requiring users to include part of their name in their passwords increases the complexity and uniqueness of the passwords, further strengthening security.
how might computers have a negative effect on the enviroment
Answer:
The negative effects of computer use on the environment There are several effects computer use has on the environment. Not only does it affect the environment but also human health.
Explanation:
First of all, sometimes people (especially in businesses) print unnecessary large amounts of files, emails or things from the internet which wastes paper and harms trees. People who use computers never really turn off the device which wastes electricity that could have been saved and reduce the amount of burning of fossil fuel.
Secondly, computers are made of heavy metals and dangerous chemicals. Heavy metals including Lead, Mercury,Beryllium,Cadmimum, PCV e.t.c
These metals and chemicals contribute to global warming because from these discarded computers it causes water contamination and air pollution.
Computers have negative effects on the environment, as heavy metals like lead and toxic chemicals found in computers contaminate groundwater and the environment.
What are the effects of computer?The harm that using computers causes to the environment The use of computers has a variety of negative environmental effects. It has an impact on both the environment and human health.
First off, printing excessive amounts of files, emails, or other content from the internet can sometimes be done by people (especially in businesses), which wastes paper and puts a strain on the environment. People who use computers rarely turn them off, wasting energy that could have been saved and lowering the amount of fossil fuel burned.
Therefore, due to the contamination of groundwater and the environment by toxic chemicals and heavy metals like lead found in computers, computers have a negative impact on the environment.

Consider a hypothetical hard drive that has 400,000 cylinders, 8 heads, and 128 sectors per track. Demonstrate, in writing, how you would calculate the total capacity of this drive. Assume a sector size of 512 bytes and express your answer in GBytes, to the nearest whole GByte, as defined in computer Science.
Answer:
The approximately capacity of a hard disk drive is 195 GB
Explanation:
sector = 512 B
Sector per track = 128 = 64 KB
cylinder = 8 * 128 (512 KB)
cylinders = 400,000 * 512 KB = 195.3 GB
Describe an application or a situation in which it is not convenient to use a linked list to store the data of the application
Answer:
A linked list is a linear data structure. In which elements are not stored at contiguous memory location. The element in a linked list using pointers.
Explanation:
"It is not convenient in case of more memory use than array because pointer storage, second it is incontiguous so it increased time period required to access individual element within the list, specially CPU cache. Third problem is that when we reverse traversing linked list."
Final answer:
Linked lists are not convenient for frequent insertions or deletions of elements, such as in a messaging application. Linked lists also do not support random access to elements based on an index.
Explanation:
An application or situation where it is not convenient to use a linked list to store data is when frequent insertions or deletions of elements are required. Linked lists have a constant time complexity for accessing elements based on their position in the list, but the time complexity for inserting or deleting elements is linear. If an application requires frequent modifications to data, using a dynamic array or a binary search tree may be more efficient.
For example, in a messaging application where new messages are constantly added and old messages are removed, using a linked list may result in slower operations to insert or delete messages compared to using a dynamic array or a binary search tree.
Another situation where a linked list may not be convenient is when random access to elements is needed. Linked lists do not support direct access to elements based on an index. If an application needs to access elements by their position in the list efficiently, using an array or an indexed data structure would be a better choice.

What is multiprogramming?
Answer:
Multiprogramming is a rudimentary form of parallel processing in which several programs are run at the same time on a uniprocessor. Since there is only one processor, there can be no true simultaneous execution of different programs. Instead, the operating system executes part of one program, then part of another, and so on. To the user it appears that all programs are executing at the same time.
Explanation:
Final answer:
Multiprogramming refers to a computer system running multiple programs at the same time by allocating system resources to multiple processes, maximizing CPU usage. It should not be confused with multitasking, which often relates to individuals performing several tasks simultaneously, a practice that can decrease efficiency if the tasks are complex.
Explanation:
Multiprogramming is a concept in computer science where a computer system runs multiple programs at the same time. This is achieved by having the operating system allocate resources to multiple processes in such a way that it maximizes CPU usage by switching between them. Each program is given a slice of the processor's time and then it is swapped out for another program, ensuring that the right amount of attention is given to each program without any one of them monopolizing the processor. This switching happens so quickly that it gives the illusion of programs running simultaneously.
While multiprogramming increases the efficiency of system resource utilization, it requires careful management of memory and CPU allocation to ensure that all programs get the necessary resources to operate effectively. It is different from multitasking, which generally refers to an individual performing several tasks at once, and often with variable success depending on the complexity of the tasks involved.
Moreover, in an agency or business context, multitasking can refer to an employee being given various roles or tasks and the need for incentives to guide not only the total effort of the employee but also the distribution of their time and effort across these tasks. This differentiation is important in designing incentives that are effective without negatively impacting the performance of the individual tasks.

A file named data.txt contains an unknown number of lines, each consisting of a single integer. Write some code that creates two files, dataplus.txt and dataminus.txt, and copies all the lines of data1.txt that have positive integers to dataplus.txt, and all the lines of data1.txt that have negative integers to dataminus.txt. Zeros are not copied anywhere.
Answer:
I am doing it with python.
Explanation:
nums = '9 -8 -7 -6 -5 -4 -2 0 1 5 9 6 7 4'
myfile = open('data.txt', 'w')
myfile.write(nums)
myfile.close()
myfile = open('data.txt', 'r')
num1 = (myfile.read())
num1 = num1.split()
print(num1)
print(type(num1))
for x in num1:
x = int(x)
if x < 0:
minus = open('dataminus.txt', 'a')
minus.write(str(x) + ' ')
minus.close()
elif x>= 0:
plus = open('dataplus.txt', 'a')
plus.write(str(x)+' ')
plus.close()
Answer:
#section 1
data = open('data.txt', 'r')
num = (data.read())
num = num.split()
data.close()
#section 2
for x in num:
x = int(x)
if x < 0:
minus = open('dataminus.txt', 'a')
minus.write(str(x) + ' ')
minus.close()
elif x > 0:
plus = open('dataplus.txt', 'a')
plus.write(str(x)+' ')
plus.close()
Explanation:
#section 1
A file data.txt containing an unknown number of lines each containing a single integer is opened.
The data is read from it and split to form a list from which the code will iterate over with a FOR loop and some conditional statements will be used to determine if the number is positive or negative.
#section 2
In this section two new files are created/ opened dataplus.txt and dataminus.txt and all the positive integers are stored in the dataplus.txt and the negative integers in the dataminus.txt.
The IF statement and elif statement used ensures that zero(0) is not captured ensuring that the code fulfills all the requirements in your question.
