Hardware, Software and Brainware

Hardware and Software Computer

Information technology up to now developed rapidly along with the discovery and development of science in the field of information and communication. This can create equipment that supports the development of information technology, ranging from communications systems to the direction of communication tools as well as two-way (interactive)

Basically, information technology equipment includes 3 main tools:

a) Computer Systems;
b) Network Communication System;
c) Net Tools

A.    Computer System

Computers are electronic devices capable of receiving, processing, and storing data, and produce output in the form of text, images, symbols, numbers and sounds. In operation, forms, systems and functions, the computer consists of 2 (two) parts of the hardware and software.

a.    HARDWARE:

To meet the needs of kinds of information, people always to develop the hardware to support it. To accommodate these interests, people create various tools that support these desires. Computer hardware devices can be classified into input devices (among others: Keyboard, Scanner), the device processes (such as: CPU), the output device and data storage (such as: Monitor, and Printer), and a data storage device (such as: CD-ROM, Compact Disk, Floppy Disk, Hard disk). More in-depth explanation about computer devices you will have also the module 3.

                          i.   

Keyboard

The keyboard is a tool to enter data or commands to the CPU (Central Processing Unit). Keyboards usually consists of a series of letters and numbers.

                         ii.   

Scanner

Scanner is a tool for entering data in the form of images / graphics and turn it into a digital form that can be processed and combined with the data in the form of text.

                        iii.    Central Processing Unit

Central processing units (CPU) is a tool that serves as a processing (processing) data. CPU is a series circuit which stores instructions instructions-processing, and temporary data storage

                       iv.   

Monitor

Monitor is a tool that can display text or images from the processed data in the CPU.

                        v.   

Printer

Printer is a tool to produce the output data (output) print the form, whether it be text or pictures / graphics.

                       vi.    CD Rom

CD Rom is the additional equipment (peripheral devices) capable of storing and writing data and programs through the media Compact Disk (CD). The tool is designed to be able to write and read data or programs through the system optics

                      vii.    Compact Disk

Compact Disk (CD) is a storage medium made of plastic materials. The process of storing and reading data using the optical system.

                     viii.   

Floppy disk

Floppy Disk is an additional tool to store or write data to disk or vice versa. Commonly used measure is the size of 3.5 inches.

                       ix.   

Hard disk

Hard Disk is an additional tool for storing data in a large capacity which is magnetically coated

b.    SOFTWARE

Software is a computer program that contains a set of instructions created by using a special language. These programs provide commands to the computer to perform various operations / processing of the data contained in the program or data entered by computer users. In short the software is the 'soul' while the hardware is functioning as the 'body' in a computer.

In general, the software can be classified into 2 (two) classes of systems software and application software. The discussion specifically about the software you'll get the module 3.

B.   Network Communication System

Communication network is a system that can connect and combine several points of communication as one that can interact with each other.

C.   Net Tools

Different ways humans use to facilitate and maintain the quality of the connection through the internet. Since then the tools that support the ability of the network (net tools) developed rapidly. Network system that had only limited use by the very populist now even to the household level.

a.    Server

A computer that works as a data provider, the provider of software and data storage is the server. Even a server able to manage information in a network path is arranged.

b.    Client

Client is a personal computer (PC) in a communication network that has the ability to process data and can request information to the server.

c.    Router

Router is a device used in a network capable of sending data to another network through a more rapid, precise and efficient.

 

d.    Modem

Modulator / demodulator is a device that allows a PC, Mini Computer, or Mainframe to receive and send data in digital form through Telephone channels
