(1)Computer Science. 1.

(2) Computing. 0. ION IN TRODUCCI. This is the index of the topic. See what you will learn and looking for a logical order in it.. I. THE COMPUTER. Overview.. II MACHINERY. Hardware.. 2.

(3) I N T R ODUC TION N • All we have long been living together and using computing devices: computers. And not just desktop computers we have at home, with your monitor, your printer etc. Also video game consoles, MP3 players, portable CD and DVD, a mobile phone .... These are all computing devices! And it all started with huge machines to handle large amounts of data automatically faster.. In this issue you'll know computers inside and out, and its main programs.. 3.

(4) I N T R ODUC TION N • Such were the first computers. They occupied entire rooms. And they had much less power than the worst today. Gradually, with the miniaturization of electronic components, they have been reduced to have computers that fit in your hand.. In the photo, computer Eniac, 1940.. 4.

(5) I N T R ODUC TION N • •. Originally, "computing"(reportsautoma tiontica) Is the part of dedicated technical teams, programs and processes for automatic data processing. • The data is numeric or alphabetic. • •. In practice, the computer has evolved into true MULTIMEDIA WORKSTATIONS (Sound, image, paper, internet ...) and its MULTIMEDIA PROGRAMS, that allow us to perform many activities with data: • TextEdit • database management • numerical calculations • graphic design • Image processing • music editing • Internet connection • contact by email, chat, video ... • Industrial process control manufacture. • Leisure: games .... • 5.

(7) THECOMPUTER We have already said that they are multimedia workstations, with their programs. From a more technical point, the computer is an apparatus for performing operations on the data automatically. We can consider it as a COMPUTER SYSTEM formed by: •. CENTRAL UNIT Data input devices. Processes the data and stores. Memoirs Data. Software. 1-MACHINERY. • •. 2-DATA. • •. Peripheral s Data output. 3-PROGRAMMES. 7.

(8) THECOMPUTER • We explain a little better this: - 1) MACHINERY (HARDWARE): They are the physical parts of the system that can be touched. Example: Printer, the tower, the monitor ... includes 3 types: -PERIFÉRICOS INPUT: They are devices that allow data entry (and programs) to the central unit. A unit CENTRAL: Are computer parts that process data. It also has memories that store data and programs. -PERIFÉRFICOS OUT: They are devices that allow data output of the central unit. -STORAGE DEVICES: They are disks and other external devices to store data. - 2) DATA: There are all sorts of information: Mathematical, alphabetical, musical, graphic ... Ex: photos, songs, jobs, numbers ... - 3) SOFTWARE (SOFTWARE): Are instructions for handling data with machinery. They are not tangible, you can not touch. They are written in computer languages Example: operating system, program text editor program program a computer game. • •. 8.

(9) THECOMPUTER interacts with the outside The computer is a tool, interacts with people or with other machines. Depending on the task will ask to be provided with the data and can ask any decision. Once this operation will automatically performed, giving a result data.. People. People CENTRAL UNIT. hines Data input. Data input devices. Processes data. Peripheral s DataData from output output.

(13) II.1. PERIPHERALSFROMENTRY. Data input devices. We have already said that they are those devices that allow data entry (and programs) to the central unit. NOTE: Some are also, simultaneously, output devices. -KEYBOARD: It is similar to a typewriter device. -THE MOUSE. It is a graphic pointer to interact with on-screen menus monitor. -PIZARRA DIGITAL OPTICAL AND PENCIL Lets note, writing, drawing ... -THE INTERNET MODEM: Provides data to other computers, especially the server computers that form the Internet. -DVD READER CD-DVD-drive. Equipment entering the data from these devices external optical storage to the central unit. The FDD was the reader of magnetic disks.. 13.
