Task 4-Purpose of different software utilities
The purpose of different software utilities is that it controls the computer’s hardware and it helps to run the computer’s application software and systems software’s help to save and protect the computer’s data.
Disk compression- A disk compression compresses the files on the hard disk to make more space to store your important data.
Backup- When you backup something you are making a copy of it and it is stored on a hard disk so if you accidently lose your data you can just use the data you backed up.
Disk defragments- Disk defragmentation increases the storage space on your hard disk by rearranging the files on the hard disk to free up more space.
Data compression- in data compression it compresses the files to make more storage and the file size …show more content…
Also an anti-virus can improve the performance of a computer because it keeps your computer secure from viruses destroying valuable data and slowing the computer down.
Firewalls- Firewalls are basically like brick walls and viruses cannot get past that brick wall which means your computer is protected. A firewall improves the performance by acting as a barrier to block out unauthorised access to the network.
Removal of cookies- when cookies store information they take up space and they may have adware also sometime that information can be used to track things so it is best to remove cookies. Cookies take a lot of storage and when they do they can slow down the computer so when you delete some cookies it improves the performance and speed.
Internet history- The purpose of internet history is to record which websites you visit which you can then browse or search. Internet history can improve the performance of a computer by removing the history as the internet history is stored so removing it will speed up the

1.[2 marks] In core task #1, you encrypted using AES-CBC with a fixed IV. What are the benefits of using a fixed IV? What are the drawbacks? The benefits of using fixed IV are to prevent the repetiton of encrypted messages become similar with the ciphertext. Besides, the drawbacks of using fixed IV are the failure not only happen in one block but the another block too because to create the another block it need the first block and the attacker will using dictionary attack if he have IV and ciphertext…

Nt1310 Unit 4 Data Analysis

Data Analysis I ran a Cochran’s Q test on the obtained classification data on an excel sheet. The Cochran’s Q test assumed a nominal independent variable of three or more treatments and dichotomous (binary) dependent variable, which were representative of the four independent variable treatments (KNN, SVM, CDA, and k-means pattern recognition algorithms) and two dependent variable outcomes (correctly classified and incorrectly classified) (Laerd Statistics, n.d.). The Cochran’s Q test also required…

Nt1310 Unit 4 Force Analysis

The fundamental four forces and their carrier Quarks and lepton are the building blocks of matter. But, what hold these particles together? All the forces in the universe and particles interactions are the result of four fundamental forces: 5.1. Gravitational Force: Gravitational force is the most pervasive force in the universe, it acts on everything that has a mass over extremely large distances. For example, a skier uses it to race downhill, the solar system is held together due to it and the…

Nt1310 Unit 4 Force Analysis

We want to understand the world around us. There are four theorised forces in our universe. These are: nuclear, strong, gravity and electromagnetic. These act very differently around us. the four fundamental forces of nature The weak force is responsible for; fission (radioactive decay), particles like muons, leptons and others with short lifetimes. This is the 3rd strongest force and only stronger than gravity. It counteracts the strong force. With a range is 10-18m which is smaller than an atom…

Nt1310 Unit 4 Network Analysis

network is two or more communication media enabled devices that are linked to each other. This allows the devices to communicate with each other, it allows resources, data and information to be transferred/shared amongst these linked devices. 2. List 4 components of communication networks The four components are the following: • Communication channels/media • Communication hardware devices • Communication protocols • Communication software 3. (a) What are the 2 ways in which communication network…
