COMPUTER MAIN PARTS

HARDWARE

The parts of the computer (physical aspect:hardware), also called devices of entry /exit (e/s), it is all that electronic gadgetrythat we observe illustrated in ourcomputer.

HARDWARE

CPU (Central Processing Unit)The CPU is one of the fundamental parts of the hardware. Contains the circuits, processors, and the memories that are running the transfers of information.

Screen or MonitorIt is a peripheral and output in its surface is luminescent in the reproduced images. The monitor is the one that

keeps the user informed of what you are doing the computer in every moment.

Mouse

It is a device of flat shape whose displacement on a flat horizontal surface is faithfully reflected in the movement

of the cursor on the screen (or monitor) display.

Floppy Drive

The floppy drives (floppy or drivers) are input and output devices that allow the load and unload massive information to the computer, as well as its storage and transportation.

Floppy Drive > Unit (or drive) CD-ROM Is the unit responsible for read an optical disc, i.e.

reading through a laser beam, non-rechargeable used for the storage of information in computer systems.

Dummy (or Recorder) CD This unit not only reads the cd's but that allows you to

record in them any kind of information, using a program especially designed for this function (Nero,

Roxio CD Creator, etc. ).

keyboard The keyboard is allows the communication with the computer

and to deposit the information.

It is fundamental to use any application. The keyboard more commonly used has 102 keys grouped in four blocks: alphanumeric keyboard, numerical keyboard, keys of function and keys of control.

Motherboard It is the printed circuit board that serves as way of connection between: the

microprocessor, electronic circuits of support, grooves to connect part or the whole RAM of the system, the ROM and special grooves (slots) that allow the

connection of cards adaptadoras additional.

SOFTWARE

The software is an indispensable ingredient computer operation. It consists of a series of instructions and data, allowing use of all

the resources that the computer has, so that it can solve many problems. A computer in itself is just a conglomerate of

electronic components; the software gives life to the computer, making its components function in an orderly manner.

Types of Software

System Software: A set of programs that manage computer resources. Examples: Central processing unit, communication devices and peripherals, software manages and controls access system hardware.

 

Application software: Programs that are written for or by users to perform a specific task on the computer. Example: text processing software to generate a spreadsheet, the application software must be on the system software to operate.

 

End-user software: The software that allow the development of some applications directly by end users, the software end user often has to work through the application software and finally through system software

Examples of software

Linux:Linux is, at first glance, an OS. It is a free implementation

of UNIX distribution for personal computers (PCs), servers, and workstations.

Microsoft WordMicrosoft Word is software intended for word processing. It was created by Microsoft, and

currently is built into the office suite Microsoft office.1

Microsoft Excel

Microsoft Excel is a distributed Microsoft Office spreadsheet application. This program is developed and distributed by Microsoft,

and is normally used in financial and accounting tasks.
