Data mining is the one method of data analysis in computing world.This is done by the method of knowledge discovery and predictive data technique.Predictive analytics focus on application of statistical or structural models for predictive forecasting or classification.

Technology

Definition and Usage

In general technology is the relationship that society has with its tools and crafts, and to what extent society can control its environment. The dictionary offers a definition of the term: "the practical application of knowledge especially in a particular area" and "a capability given by the practical application of knowledge". In her 1989 "Real World of Technology" lecture, gave another definition of the concept; it is "practice, the way we do things around here". The term is often used to imply a specific field of technology, or to refer to high technology or just customer electronics, rather than technology as a whole. Technology in two ways: as "the pursuit of life by means other than life", and as "organized inorganic matter."

Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. It is a far-reaching term that may include simple tools, such as a wooden , or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material; virtual technology, such as computer software and business method, fall under this definition of technology.

The word "technology" can also be used to refer to a collection of techniques. In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfy wants; it includes technical methods, skills, processes, techniques, tools and raw materials. When combined with another term, such as "medical technology" or "space technology", it refers to the state of the respective field's knowledge and tools. "State-of-the-art technology" refers to the high technology available to humanity in any field.

Technology can be viewed as an activity that forms or changes culture. Additionally, technology is the application of math, science, and the arts for the benefit of life as it is known. A modern example is the rise of communication technology, which has lessened barriers to human interaction and, as a result, has helped spawn new subcultures; the rise of cyberculture has, at its basis, the development of the Internet and the computer.Not all technology enhances culture in a creative way; technology can also help facilitate political oppression and war via tools such as guns. As a cultural activity, technology predates both science and engineering, each of which formalize some aspects of technological endeavor.

Information Security

INFORMATION SECURITY

Definition:

Information security refers to protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. The goals of information security include protecting the confidentiality, integrity and availability of information.

All organizations, including governments, military, financial institutions, hospitals, and private businesses, gather and store a great deal of confidential information about their employees, customers, products, research, and financial operations. Most of this information is collected, processed and stored on electronically and transmitted across networks to other computers. Protecting confidential information is a business requirement, and in many cases also an ethical and legal requirement. For the individual, information security has a significant effect on privacy and identity theft.
The field of information security has grown significantly in recent years. There are many areas for specialization including Information Systems Auditing, Business Continuity Planning and Digital Forensics Science, for example. There are also specific information security technical certifications that can assist getting started in this field.

Computer Networking Information:

Computer Networking:

Computer Networking is a focus within engineering that deals with communication between computer systems or devices. Computer networking is often considered a sub-discipline of a few areas: telecommunications, computer science, information technology and/or computer engineering. Computer networks rely heavily on the theoretical and practical application of each of these engineering disciplines.
A computer network is any set of computers or devices connected to each other with the ability to exchange data. Examples of different networks are:
1) LAN
2) MAN
3) Wireless LANs (WLAN)
4) Wireless WANs

DBMS

Definition:

A database is a collection of records or data that is stored in a computer system. The structure of a database is dependent on how the data is organized, according to a particular database model. Today we commonly use a relational database model. Other models include a hierarchical model and the network model.

A computer database relies on software to organize the data and how it is stored and retrieved. The type of software used for this is called a database management system (DBMS).

Database management systems are categorized according to the database model that they support. The model, in turn, determines the query languages that are available to access the database. This determined how the data is retrieved, manipulated and then used to make business decisions. Other important issues that a DBMS addresses include managing performance, concurrency, integrity, and recovery from hardware failures.

Information Technology

We use the term information technology or IT to refer to an entire industry. In actuality, information technology is the use of computers and software to manage information. In some companies, this is referred to as Management Information Services (or MIS) or simply as Information Services (or IS). The information technology department of a large company would be responsible for storing information, protecting information, processing the information, transmitting the information as necessary, and later.

History of Information Technology:

In relative terms, it wasn't long ago that the Information Technology department might have consisted of a single Computer Operator, who might be storing data on magnetic tape, and then putting it in a box down in the basement somewhere. The history of information technology is fascinating! Check out these history of information technology resources for information on everything from the history of IT to electronics inventions and even the top 10 IT bugs.
