Public health informatics (PHI) denotes the logical application of computer science, information, as well as technology to the practice of public health, learning, and research (O'Carroll, 2013). PHI is an interdisciplinary vocation that uses engineering, mathematics, information science, as well as related social sciences to significant public health processes and problems.

The field of informatics has been applied and is significant in the components of public health involving public health surveillance, nursing, environmental health, emergency response, and administration. Public health informatics has provided methods or techniques for attaining goals of public health in a ...

Introduction

The report will give an overview of the careers in information technology. Information technology has grown to be a field that has many careers. Technology has changed the field so that it has many emerging careers. The report will give ...

Computer scientists often have the thought of having an important place within the society. They will strive to show everyone in the world how their views have the most positive effects on the entire globe. The use of computers has been a major boost on the current world because many activities are made simple. Communication across the world and all the bulky activities that involved the human nature to carry out have been made simply by programming a computer to take instructions from a human (Agans, 2002). The computer is programmed to carry out a multitude of activities including accepting data, processing the ...

As a discipline, computer science was evidently misnamed. The facts that supports this notion are indeed numerous and weighty to a large extent. The individuals who named the discipline wrongly projected it as a science. The discipline fails to meet the criterion and standards of a science. The name could have been coined with the aim of making the discipline get a higher status, and consequently earn more respect from the public. There are numerous facts and reasons that help in trashing the notion of this discipline as a science and relevantly link it to engineering.

Computer science is generally concerned with the making of ...

This is a computer mainly meant for use in the day-to-day operational activities in the school office. This specification note will be submitted to several suppliers such that those with the most favorable terms will supply the product. The computer should be a desktop with a stand. The desktop have ability to adjust it brightness with the LD screen.

Purpose of the computer:

The main purpose of this product is to perform the daily activities in the office like recording, processing data as well as presenting data in of graphs, tables and charts for faster decision making. The computer is also meant for storing massive data ...

Information systems (IS) is defined to be the study of complementary networks of software and hardware which individuals and organizations use in collecting, processing ,filtering, creating, and distributing data .This study of information systems merges computer science with business by employing computation and information theoretical foundations.

Before the emergence of the modern discipline of computer science in the twentieth century, there existed a coincidence between the history of computer science and information systems. Generally, information systems mainly focus on processing information within organizations, which largely incorporates the business enterprises, and sharing the benefits with modern society. The circulation of information ...

The SQL injection (SQLi) is one of the most common threats to contemporary computer security. It is also one of the most successful threats because it is easy to execute and moderately hard to detect and prevent, so the success rates are high and the damaged caused by the attack is severe. Furthermore, there are no tools that can accurately detect and stop specific SQLi attacks, so developers are required to analyze the source code and resort to code-based defense strategies if they want to prevent unauthorized access to data. In the worst case scenario, an attacker can take ...

I. Proper communication skills are very essential in everyday life activities. They must just determine your next promotion or the new contract that your client will sign for you. They might just as well find you a spouse. It is the weapon for influence one should never underestimate that. Even persuasion will rely on how effective communication is. Several attributes are required in a person in order to become a good communicator. Self confidence is among the most emphasized communication skills that many talk about. Well, it is a key trait but there is much more to just being confident for you to ...

Kohonen Network

While not the first of its kind, the Self-Organizing Map is a form of artificial neural network that became useful because of its use in visualizing and analyzing high-dimensional data on a low-dimensional scale. It gained its common name, the Kohonen Network, after a Finnish professor by the name of Teuvo Kohonen introduced it to the world .

What made it different from early neural network models is the fact that in these early neural network models, the self-organizing power was weak; thus this made the Kohonen Network crucial is that is composed no less than two interacting subsystems which are different in ...

According to Raunch (2011), two main factors make one algorithm look better than the other algorithm. Firstly, the nature of efficiency of the algorithm in terms of the time taken to complete a given calculation and generate the required results determines the suitability of one algorithm from the others. Algorithms use two main search methods, binary search and sequential search. A binary search divides entries into two and then decides which entry has the ability to give quicker results. On the other hand, the sequential search runs a one by one search until it gets the desired results of an entry. ...

Health Information Systems is a discipline that connects computing and information technology and health care practices and research. Computer hardware, software and communication equipment, forming a complex network. It entails the resources, equipment and means of obtaining, storing, retrieving and analyzing information in the health sector. This involves use of programmed systems to manage health information and securely exchange it between patients, health institutions, insurers and even government agencies. This interaction will improve value, safety and effectiveness of health delivery. These health information systems will find application in multiple healthcare disciplines including nursing, public health, pharmacy, pathology and dentistry.

One example of a large number is bits that are found in the computer hard disk. As of the year 2011, the largest hard disk has a size of 1000 Gigabytes (GB). Computer scientists make use of bits when representing data and when doing scientific computations. 1 GB is equivalent to 1024 Megabytes (MB) while 1 MB is equivalent to 1024 Kilobytes (KB). 1 KB is equivalent to 1024 Bytes. 1 Byte is equivalent to 8 bits. The latest hard disk is therefore equivalent to 1000*1024*1024*1024*8 which translates to 8589934592000 bits. In scientific notation, this is equivalent ...
