Binary

As the formal meaning, binary it's "composed by two units". In our particular object of study, it's related to "0" and "1", the basic unit used in the logic of computation, which 0 will be a "closed" logical and 1 will be "open"
The combination of the binary numbers -in different order- are the foundation of computing.

BIT (binary digit): A bit (short for binary digit) is the smallest unit of data in a computer. A bit has a single binary value, either 0 or 1.

                     

INFORMATICS

Branch of engineering that studies the information processing by using automatic machines. It is a broad field that includes the theoretical foundations , design , programming and the use of computers as tools for troubleshooting.

Controller

software element used in various operating systems, also called device driver, device driver or driver.

WEB

Means "world wide web" and as a spider web, it connects every computer on a link that allows to communicate each other

GIGABYTE

The gigabyte is a multiple of the unit byte for digital information.

The prefix giga means 10⁹ in the International System of Units (SI), therefore one gigabyte is 1000000000bytes. The unit symbol for the gigabyte is GB.

Keyloggers 

(Key ( key) and Logger (record) - Key Logger ) is a type of software that is responsible for recording keystrokes that are made on the keyboard, to memorize them in a file and / or send them via internet .

Web

It is a word Englishman that means "network", "spiderweb" or "mesh". The concept is in use in the technological area for naming to an IT network and, in general, to Internet (in this case, it is in the habit of being written as Web, with the capital W). The term, anyway, it has several uses. Beside naming Internet in general, the web word can serve mention to a web page, a web site or up to a web servant

Variable

In programming, a variable consists of a space in the storage system (main memory of a computer) and a symbolic name (identifier) ​​that is associated with that space. That space contains a quantity or information known or unknown, that is a value. The variable name is the usual way of referring to the stored value: this separation between name and content allows the name to be used regardless of the exact information they represent. The identifier in the source code of the computer can be linked to a value at runtime and the value of the variable can therefore change during the course of program execution. The concept of variables in computer may not correspond directly to the concept of variables in mathematics. The value of a variable in computing is not necessarily part of an equation or formula and math. In computing a variable can be used in an iterative process: be assigned a value in one place, then using it in another, later reassigned to a new value for later use in the same manera.Procedimientos of this type are known by the name iteration. In computer programming, variables, often assigned to make relatively long descriptive names for use, while the variables in mathematics often have bare names, consisting of one or two characters to brief on their transcript and handling.

The Internet

Internet is a set decentralized of interconnected networks of communication that use the family of protocols TCP/IP, which guarantees that the physical heterogeneous networks that compose it work as the logical only network, of world scope. His origins go back 1969, when there was established the first connection of computers, known as Arpanet, between three universities in California and one in Utah, The United States.

DECIMAL

Also called decimal system, numbering system is a positional numeral system in which quantities are represented using arithmetic based powers of the number ten. The set of symbols used (System of Arabic numerals) consists of ten digits: zero (0) - one (1) - two (2) - three (3) - four (4) - five (5) - six (6) - seven (7) - eight (8), nine (9).

A software developer is a person whose work is to research, analyze, design, implement and test software that was required by a specific company or client. A software developer can also create applications for anyone to use that can be distributed in many ways across the internet or platforms dedicated to distribute them. Software developers can be analysts or programmers and they normally work in groups to be able to create software faster.

INTERNET

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks for file sharing and telephony.
