1.1 Definition Digital describes electronic technology that generates, stores, and processes data in term of two states which positive and nonpositive. Positive is expressed or represented by the number one while non-positive by the number of 0. Thus data transmitted or stored with digital technology is expressed as a string of 0’s and 1’s. Each of these state digits is referred to as a bit. Literacy is the quality or state of being literate, especially the ability to read and write, to…

Task 9 For this task I must compare the usefulness of maintaining a database with MySQL compared with if I were to use the query language (QBE). For this task I will need to evaluate the advantages for both the languages, as well as the disadvantages, to find a conclusion which is evenly presented for both of the languages. Advantages and Disadvantages Although the two languages interlink in many different ways they have many different features that must be noticed by the user before the use of…

a) The Zipf discrete distribution derives from Zipf’s law which states that popularity of ith-most popular object is proportional to i-α, (α: Zipf coefficient). When applied to the words in English language, it means that the frequency of occurrence of a word is inversely proportional to its place in the frequently occurring words table ranked accordingly. Or…

Summary of research and outcome: My investigation focused on exploring the effects of anxiety on the cognitive functions of the body and establishing some effective treatments. The topic was inspired by my interest in medicine and mental disorders that affect large proportions of the contemporary populace. A vast array of research processes was conducted to in order to determine the various effects of anxiety on the functions of the brain. More specifically, a series of literature reviews,…

The literature that is reviewed in this piece was compiled from a variety of online databases and resources. Using Husson University’s library, I found there were many different databases available to use for the research. I selected from the following online databases; PubMed, Medline, Academic Search Complete, EBSCOHost, and the American Psychological Association. The original terms included physical therapy, gross motor skills, and cerebral palsy. However, as I narrowed the broad subject of…

The rules of Logic specify the meaning of mathematical statements, it is the basis of all mathematical reasoning (Rosen, 2012). Its application in the area of computer science is very vast that even the computer itself defends on it, True or False, 1 or 0, and the presence or absence of bit. The study of Logic will increase your knowledge in formulating logically statements for the reason that program statements and expressions is built from repeated application of logical operators. This module…

digital images by means of a digital computer. It is subcategory or field of digital signal processing. Digital image processing has many advantages over analog image processing. It is the act of examining the image for the purpose of identifying the object and judging their significance. Computer vision and image analysis are two examples of related areas to image processing. We can differentiate between them by the input and the output. In image processing the input and the output are…

Non parametric tests It is a hypothesis test which does not need population distribution. For instance there are numerous hypothesis tests which depend upon assumptions that population must be normally distributed along with the parameters. Main advantages of non- parametric tests are that they do not rely on assumptions, so they can be easily used where population is non-normal. One thing to be kept in mind, that these tests may have few assumptions related to the data. They might not be…

D1 - Discuss how potential errors in the design and construction of a database can be avoided. Accidental deletion of fields When a database is being used you might find it easy to accidently delete data which could mean a lot of stress if it is something which is very valuable. One main way to avoid this would be to make sure that back-ups are made of the data, so whatever the matter the data will not be completely lost. Back-ups can be stored on anything like a memory stick or an external…

Nelson Mandela once said, “Education is the most powerful weapon which you can use to change the world.” However, in Woody Allen’s, “The Rejection,” the writer satirizes the ideals of the education system that acknowledges only the intelligent students. This is seen in the character of Boris through his exaggerated reaction towards the failure of his son. During the time of Woody Allen, he believed that education was only for the smart and intelligent people. Woody Allen satirizes the education…
