Information: It is the result of processing data. For example data are given as three words: Red, Auto and Richard and processing requests certain criteria to form a sentence. The sentence: 'The red car is Richard‖ is information.
Storage units: The computer stores data in binary format. This means that employs devices that have only two, corresponding to on and off states possible.
The BIT is the smallest unit of data measurement and it may be 0 or 1. For example, to store A LETTER it requires 8 bits (equivalent to 1 byte). To calculate the following units of measurement is taken at the base and an exponent rises increasing.
The higher the bit units are expressed in units of 1024 to 1024. The difference in values 1024 (rather than 1000 of the International System) is because working in binary power 2 would be 210 which is equal to 1024 and is the closest to 1000.
Examples of using the units of measurement to describe the information that is stored: A simple text document with the message "Hello world" occupies a total of 10 bytes, an MP3 music file 3.23 minute occupies approximately 3.23 Megabytes, A high-definition video lasts 0.33 seconds (depending on resolution) occupies approximately 4.14 Megabytes.
Computers and software: Computing and information technology are two sciences that complement the study of computer and activities of automated information processing.
Computing: Computare comes from Latin and means -contar‖ or -calcular‖. Although its meaning is linked to the numbers today is considered a science that studies the physical part of the computer.
Computing: It comes from the French Informatique, created in 1962 by Ph. Dreyfus as an acronym for reports (tion) and (AUTO) ticket. Informatics is the science that studies the logic of the computer.
Hardware: It refers to the physical part of the computer (HARD means -duro‖), ie, the set of parts that are assembled to form what people call computers and other devices. all The term to generalize what you can see, feel and check your física structure is used.
Types of Hardware:
Software: Is the set of programs that control the computer and the way she works. The essential software component that is available to the user is the operating system.

DEFINITIONS
Data: Every object in the universe has immersed him data, such as human beings possess innumerable data such as weight, height, skin color, age, etc. even a simple object possesses, for example a stone will have weight, width, height, level of roughness, etc.Information: It is the result of processing data. For example data are given as three words: Red, Auto and Richard and processing requests certain criteria to form a sentence. The sentence: 'The red car is Richard‖ is information.

TABLE OF UNITS OF MEASUREMENT
Unit of measure Equivalence:bit 0 or 1, byte 8 bits, Kilobyte (KB) 1024 bytes, Megabyte (MB) 1024 Kilobytes, Gigabyte (GB) 1024 Megabytes, Terabyte (TB) 1024 Gigabytes, Petabyte (PB) 1024 Terabytes, Exabyte (EB) 1024 Petabytes
Examples of using the units of measurement to describe the information that is stored: A simple text document with the message "Hello world" occupies a total of 10 bytes, an MP3 music file 3.23 minute occupies approximately 3.23 Megabytes, A high-definition video lasts 0.33 seconds (depending on resolution) occupies approximately 4.14 Megabytes.
TABLE OF CHARACTERS AND SYMBOLS
Character tables are standards adopted by the software industry in different regions of the world to standardize the representation of characters, numbers and symbols that are obtained with the keyboard. So the table has to be adopted by Windows is the ANSI table. But there are other well-known as the ASCII table. ASCII (American Standard Code for Information Interchange - American Standard Code for Information Interchange) codes includes 256 codes (0 to 255).DATA PROCESSING
Automated Data Processing (PAD) is comprised of four main stages:- Input. It is the initial stage of PAD and refers to the entry of data into the computer through input devices or means (keyboard, mouse, scanner, etc.).
- Process. For the handling and manipulation of previously entered information (microprocessor, integrated circuits, data bus, etc.) phase.
- Storage. Intermediate phase in which the data is stored in a storage device for later retrieval or processing (hard disk, flash memory, etc.).
- output. Final phase of transformed data representation also called results for what you can use devices such as monitor, printer, etc.

Types of Hardware:
- Input: Are those that allow the user to input information into the computer outside. These are: keyboard, mouse, scanner, microphone, camera, etc.
- Output: Are showing the user the result of the operations performed by the PC. In this group they are: Monitor, Printer, Plotter, etc
- Input / Output: These are devices that can simultaneously provide information outside the PC and the user, many of which are used for storing and retrieving data. Here they are: Modem (Modulator / Demodulator), ZIP, CD-ROM, DVD-ROM, HD-DVD, Blu-Ray Disc, USB Flash Memory, Hard Drive
Software: Is the set of programs that control the computer and the way she works. The essential software component that is available to the user is the operating system.
